Sprøjtestøbning af aluminium

The aluminum injection mold is a key part of the manufacturing industry today due to its speed, efficiency and affordability. With the need for faster production cycles and flexibility of design, industries have found aluminum molds to be useful. The plastic pieces are created by injecting the melted plastic material into a cavity precisely made, and the plastic material assumes the shape of the cavity while cooling. Aluminum molds have a much shorter lead time, are easier to machine and are significantly lighter in weight than steel molds. This is a great option for prototypes and low and medium production runs. This is a preferred method for companies, since it saves them time in constructing their application and guarantees that the routine is developed with high quality. With the improvement of technology, the application of aluminum injection molds is rapidly increasing in various industries including automotive, medical, electronics and consumer goods.

What is an Aluminum Injection Mold?

An aluminum injection mold is a mould that is utilized to form plastic parts. It is made out of aluminum and not steel. In this, the plastic is melted and then injected into a mold cavity. The material cools then replicate the shape of the mould. After it’s cooled, the final product is removed. Occurs in numerous repetitions in production process. The greatest benefit is that it cools faster and produces faster than other materials, such as plastic. The most important benefit is that it cools down quickly, and produces faster than plastic materials. That’s why today, aluminum injection molds are used.

How Aluminum Molds Work in Injection Molding?

Aluminum injection molding molds need to have a specific procedure to undertake and they are fairly efficient. Every step is dependent on the others and is crucial to producing high quality plastic components in a fast and reliable manner.

Step 1: Material Selection and Preparation

The first thing to do is to select a suitable plastic. ABS, polypropylene and polyethylene are typical materials used. There are a number of materials with different characteristics, such as strength, flexibility and resistance to heat. This is normally given in the pellets form in a hopper above the machine. Prior to use the material must be clean and dry, otherwise moisture can cause defects in the product.

Step 2: Feeding the Plastic into the Machine

Then the mould is set up and plastic pellets are placed in the injection molding machine. These are fed into the hopper where they are heated in a barrel. A screw which rotates inside the barrel pushes plastic forward. While moving, the material starts to heat up which begins to melt the material.

Step 3: Melting the Plastic

The heat and pressure generated by the screw, melts the plastic in the barrel. As time goes on, solid pellets will slowly be converted into a thick substance known as “molten plastic”. It is very important to have control on temperature here. Too hot could cause damage to material while too cool could cause a problem with melting.

Step 4: Injection into the Aluminum Mold

When it is completely dissolved, the plastic will be injected. The screw imparts a high pressure on being pushed. The molten plastic is forced into the aluminum injection mould with the help of a nozzle. The shape of the mold cavity is determined by the shape of the product to be produced, in order to get accurate results.

Step 5: Filling the Mold Cavity

The plastic is melted and poured into the mould to completely fill in all of the spaces. Fills out all the information and forms, and makes all the shapes completely. To prevent an air bubble and void, the proper pressure is applied. This step is very significant as it is otherwise the product will be faulty.

Step 5: Filling the Mold Cavity

After being filled, the cooling process begins. Aluminum has a very high heat transfer, thus the plastic cools rapidly. The temperature is kept constant by using cooling channels. The plastic hardens and the shape of the mold is created as the plastic cools. The colder the metal, the quicker will the cycle take and the quicker will production be.

Step 7: Mold Opening

When the plastic material is completely set, the mould is carefully and slowly removed from the plastic. This is to ensure that there will be no damage to the mold. At this stage the mold consists of two parts which separate. Once the part is molded, it is easily ejected from the mold. This process is very time sensitive. It is important that the mold is not opened too early, as the product could bend or lose its shape. Manufacturers always wait until the plastic is solid before opening the mold that is why.

Step 8: Ejection of the Finished Part

When the part is molded, the ejector pins act to eject the molded part from the mold. Careful removal of component – no damage. It is then to be taken away for the next procedure. If you have a well-designed ejection system, then no marks or defects will be left on the surface.

Step 9: Inspection and Finishing

They are quality checked after being removed from the plant. Manufacturers test for any shape defect, bubbles or cracks. Some finishing (cutting and/or smoothing) is done as needed (minor). Aluminum moulds provide a good surface quality, and generally require minimal finishing.

Step 10: Repeat the Cycle

The mold will be ejected and the cycle repeated when the mold is closed. This allows for parts to be produced from one-off to mass production. Faster cooling of aluminum results in reduced cycle time, which makes the process more efficient and helps to reduce production costs.

Termoplast er de materialer, der kan smeltes og støbes igen og igen, uden at deres egenskaber forringes. Det betyder, at de er meget alsidige og kan tilpasses andre anvendelser.

Fremstillingsproces for termoplastisk sprøjtestøbning

1. Valg af materiale

Det første trin i sprøjtestøbning af termoplast er processen med at vælge det rigtige materiale, f.eks. polypropylen, ABS, polycarbonat, normalt termoplastiske pellets. Sådanne materialer vælges afhængigt af deres egenskaber såsom styrke, plast, varmebestandige egenskaber og pris. Den sprøjtestøbte termoplast er det passende materiale, der giver optimal funktionalitet og styrke til delen.

2. Smeltning af termoplast

Dette indebærer smeltning af termoplasten for at opnå den nødvendige form og volumen til at fylde støbemaskinen. Smeltning af termoplast: Det gøres for at smelte termoplasten til den ønskede form og volumen og hælde den i støbemaskinen.

I en varm tønde på sprøjtestøbemaskinen anbringes de rå plastpiller. Blandingen af pellets i tønden er homogen og tyktflydende. Temperaturen i denne fase er meget relevant, så nedbrydningen og den jævne afvikling af støbeprocessen kan sikres.

Formen bruges til at sprøjte det nye produkt ud på markedet.

3. Indsprøjtning i formen

Når termoplasten udsættes for den rette temperatur, presses den ind i et formhulrum af den ønskede størrelse. Emnets form og karakter bestemmes af formen. Porte, åbninger og kanaler konstrueres på den rigtige måde, så det smeltede materiale strømmer jævnt ind i formen og minimerer defekter. Dette er en af de nødvendige operationer ved indsprøjtning af termoplast.

4. Nedfrysning og genfrysning

Når plasten er i formen, smelter den og størkner. Den tid, der kræves til afkølingsprocessen, bestemmes af materialet, væggenes tykkelse og komponentens kompleksitet. Afkølingen skal være ensartet, så den ikke bliver skæv, synker eller krymper.

5. Formåbning og udstødning af emner

Derefter størkner delen, formen åbnes, og det færdige produkt skydes ud. Dette gentages derefter gennem kontinuerlig produktion. De moderne maskiner er automatiserede, og de har computerstyring, som sikrer, at den samme del bruges i de forskellige kørsler, som giver den samme del af høj kvalitet.

6. Forarbejdning og efterbehandling

Selv termoplastiske komponenter, der er sprøjtestøbt, kan have brug for yderligere efterbehandling, f.eks. trimning, maling eller samling. Det er processer, der gør emnet funktionelt og æstetisk acceptabelt.

Almindelige fejl i termoplastisk sprøjtestøbning og hvordan man undgår dem

Det er en ekstremt effektiv proces, som kan blive defekt, når produktionsprocessen finder sted. Sprøjtestøbning er termoplastisk og er kendt for at have skævheder, synkemærker, korte skud og flash. Når emnet afkøles i en anden hastighed, bliver det skævt og bøjer derfor emnet. Gode kølesystemer kan bruges til at minimere dette. Sinkmærker er små prikker på overfladen, som normalt skyldes forkert tryk eller afkølingstid.

Korte skud udføres, når formen ikke er fyldt helt op, hvilket er almindeligt på grund af lavt indsprøjtningstryk. Men det overskydende, der hældes ud af formens hulrum, blinker. Sådanne problemer kan forhindres ved at designe passende forme og maskinkonfiguration under sprøjtestøbning af termoplast.

Vigtigheden af formdesign i sprøjtestøbning af termoplast

Design af støbeforme er meget afgørende for, om sprøjtestøbning af termoplast bliver en succes. En god form giver et godt materialeflow, nem afkøling og nem udstødning af den færdige del.

Overvejelserne om formens design er placeringen af porte, køling og udluftning. Materialet kan fylde formen jævnt op og skabe minimale defekter, når portene er placeret korrekt. Kølekanalerne anvendes til at opretholde de homogene temperaturer, og det forbedrer produktkvaliteten.

En sprøjtestøbt termoplast har en form af høj kvalitet, der ikke kun forbedrer effektiviteten, men også forbedrer produktionslængden.

Temperatur- og trykreguleringens rolle

Temperatur og tryk er nogle af de vigtigste parametre, der er involveret i processen. Når termoplast sprøjtes ind, vil den rette temperatur sikre, at stoffet flyder ordentligt, og at det fylder formen helt ud. Uønsket varme kan ødelægge materialet. Med lave værdier er der sandsynlighed for, at der opstår defekter, fordi materialet ikke flyder som forventet. På samme måde kræves der et tilstrækkeligt tryk for at sikre, at formen har en ensartet fyldning.

Disse variabler kontrolleres nøje for at forbedre produktkvaliteten og reducere spild under sprøjtestøbning af termoplast.

Fordele ved sprøjtestøbt termoplast i produktdesign

Den termoplastiske sprøjteplast er meget gavnlig i produktdesign. Designere kan også finde på komplicerede former, tynde vægge og detaljerede funktioner, som ville have været vanskelige at opnå på andre måder. En anden fordel ved sprøjtestøbt termoplast er, at der er mulighed for at tilføje flere dele i en enkelt komponent. Det sparer tid på samlingen og øger produkternes holdbarhed.

Designet er tilpasningsdygtigt, så en virksomhed kan blive kreativ og opfinde unikke produkter, der kan differentiere sig på markedet.

Sammenligning af sprøjtestøbning af termoplast med andre plastprocesser

Der er forskellige processer til fremstilling af plast, men termoplast gennem sprøjtestøbning er effektivt og præcist. Form- og detaljekontrollen ved sprøjtestøbning er bedre end processer som blæsestøbning og ekstrudering. Det er mest hensigtsmæssigt, når det drejer sig om hårde materialer med komplekse profiler.

På trods af at sprøjtestøbning af termoplast måske ikke egner sig til nogle af anvendelserne, er det velegnet til produktion af store mængder, hvor kvaliteten af de anvendte emner skal være konstant.

  • Let i vægt sammenlignet med metaller.

Produktionen af sprøjtestøbning af glasfyldt nylon garanterer ikke kun holdbarheden af delene, men gør dem også omkostningseffektive, når det drejer sig om masseproduktion.

Fysiske, kemiske og mekaniske egenskaber

Artiklen med titlen Sprøjtestøbning af glasfyldt nylon er en blanding af nylon, som har en høj grad af fleksibilitet, og glasfibre, som har høj styrke og giver unikke egenskaber. Viden om disse hjælper med at skabe troværdige komponenter.

Fysiske egenskaber

  • Tæthed: 1,2 -1,35 g/cm 3, hvilket er lidt tungere end ufyldt nylon.
  • Absorption af vand: 1-1,5% (30% glasfyldt) falder, når indholdet af fibre øges.
  • Termisk ekspansion: Lav dimensionel stabilitetskoefficient (1535 µm/m -C)

Kemiske egenskaber

  • Modstandskraft: Høj i forhold til brændstoffer, olier og de fleste kemikalier.
  • Brandfarlighed: A V-2 til V-0, afhængigt af klasse.
  • Korrosion: Ikke korroderbar som metaller, perfekt i ugunstige miljøer.

Mekaniske egenskaber

  • Trækstyrke: 120-180 Mpa, og det afhænger af fiberindholdet.
  • Bøjningsstyrke: 180-250 MPa.
  • Modstandsdygtighed over for slag: Medium, og reduceres med en stigning i fiberindholdet.
  • Stivhed: Stivheden er høj (5 8Gpa), hvilket giver stive bærende komponenter.
  • Modstandsdygtighed over for slid: Det er overlegent i gear, lejer og bevægelige elementer.

Sprøjtestøbningsprocessen

Sprøjtestøbning af glasfyldt nylon sker ved at smelte kompositmaterialet og derefter sprøjte det ind i en form under højt tryk. Proceduren kan opdeles i flere trin:

  • Forberedelse af materialet: Sammensætningen af den rette mængde glasfiber og nylonpiller blandes.
  • Smeltning og injektion: Materialet opvarmes, indtil det er smeltet, hvorefter det presses gennem en form.
  • Køling: Det er en størkningsproces, hvor fibrene fikseres.
  • Udstødning og efterbehandling: Rudimentet af det faste stof tages ud af formen og vil sandsynligvis blive trimmet eller poleret.

Glasfibrene i den glasfyldte nylon til sprøjtestøbning hjælper emnet med ikke at miste sin form og styrke, når det er kølet ned. Det er især nødvendigt ved snævre tolerancer og meget komplekse designs.

Sprøjtestøbningsprocessen

Fordele ved at bruge glasfyldt nylon

I det hele taget gør udtrykket sprøjtestøbning af glasfyldt nylon det muligt for producenter af højtydende dele at skabe deres dele effektivt og imødekomme behovene i den moderne industri.

Tips til forarbejdning af glasfyldt nylon

Når Indsprøjtning af glasfyldt nylon, er det vigtigt at være opmærksom på materialets opførsel og maskinens indstillinger. Flow, køling og termiske egenskaber ændres af tilstedeværelsen af glasfibre. Når de korrekte instruktioner følges, kan sprøjtestøbning af glasfyldt nylon resultere i robuste, præcise og fejlfri komponenter.

Tips til forarbejdning af glasfyldt nylon

Forberedelse af materiale

Glasfyldt nylon er let at bruge som et fugtabsorberende materiale. Vådt materiale kan føre til bobler, hulrum og dårlig overfladefinish. Tør materialet ved 80-100 °C i løbet af 46 timer. Sørg for, at glasfibrene ikke klumper sig sammen i nylonet for at opnå en ensartet styrke.

Smeltetemperatur

Hold den anbefalede smeltetemperatur for nylonkvalitet:

  • PA6: 250-270°C
  • PA66: 280-300°C

For høj temperatur kan ødelægge nylonet og ødelægge fibrene, mens for lav temperatur forårsager dårligt flow og utilstrækkelig fyldning ved sprøjtestøbning af glasfyldt nylon.

Indsprøjtningstryk og -hastighed

Moderat indsprøjtningshastighed og tryk: 70 -120 Mpa er normalt. Hurtig indsprøjtning kan deformere fibrene og forårsage stress i fibrene. En passende hastighed giver ikke kun et jævnt flow, men også en ensartet fiberorientering, hvilket giver stærkere dele.

Formens temperatur

Overfladefinish og målnøjagtighed afhænger af formens temperatur. Oprethold 80-100 °C. Lave temperaturer i formen kan give skævvridning og synkemærker, mens høje temperaturer forbedrer flowet og reducerer cyklustiden.

Køletid

Vægtykkelsen skal være lig med afkølingstiden. Hvis den er for kort, bliver den skæv, og hvis den er for lang, bliver den mindre effektiv. Korrekte kølekanaler er med til at sikre en ensartet afkøling og nøjagtige dimensioner i sprøjtestøbningen af glasfyldt nylon.

Dette er, hvad der sker med den, når den bliver skubbet ud og efterbehandlet

Brug 1-2 graders udkastningsvinkel for at opnå en jævn udstødning. Det er vigtigt at undgå for stor udstødningskraft, der kan trække i fibrene eller knække emnet. Efter bearbejdningen kan der være tale om trimning, polering eller udglødning for at løse indre spændinger.

Overvejelser om fiberindhold

Indholdet af glasfiber er normalt 30 50% i vægt. En stigning i fiberindholdet øger styrken, stivheden og varmetolerancen, men mindsker slagsejheden. Kontrollér forarbejdningsparametrene for at undgå defekter ved at justere fiberindholdet.

Potentielle erstatninger for glasfyldt nylon

Selv om glasfyldt nylon med sprøjtestøbning er stærkt og holdbart, er der nogle gange bedre materialer at bruge til visse krav.

  • Ufyldt nylon (PA6/PA66): Nylon er let, billigere og enklere at arbejde med, og det anbefales til arbejde med lav belastning, men det er ikke så stift som glasfyldt nylon.
  • Polykarbonat (PC): Slagstyrken og varmebestandigheden er høj, og stivheden er mindre end ved sprøjtestøbning af glasfyldt nylon.
  • Polyphenylensulfid (PPS): Det er meget stærkt i både kemisk og varmebestandighed og kan bruges i applikationer med høje temperaturer på bekostning af.
  • Acetal (POM): Dimensionsstabilitet, lav friktion og svag varmebestandighed og stivhed.
  • Fiberforstærkede kompositter: Forstærkningsfibre af kulstof eller aramid er stærkere, stivere, mere komplicerede og dyrere at bearbejde.

Egenskaber for glasfyldt nylon

Glasfyldt nylon i form af sprøjtestøbning foretrækkes på grund af de gode mekaniske og termiske egenskaber, det har, og som kvalificerer det til at modstå de krævende anvendelser. Tilsætningen af nylon med glasfibre øger materialets styrke, stivhed og dimensionsstabilitet. Her er de vigtigste egenskaber:

Høj trækstyrke

Nylonholdige glas er modstandsdygtige over for store træk- og strækkræfter. Det gør sprøjtestøbning af glasfyldt nylon velegnet til strukturelle komponenter i bilindustrien og industrien.

Fremragende varmebestandighed

Glasfibre forbedrer den termiske stabilitet, så delene kan være stærke ved høje temperaturer. Det er afgørende for de elementer, der udsættes for motorvarme eller elektronisk udstyr.

Dimensionel stabilitet

Glasfibrene minimerer sammentrækningen og deformationen under afkøling. Processen med sprøjtestøbning af glasfyldt nylon skaber dele, der ikke mister deres form og nøjagtige mål, selv i komplekse designs.

Forbedret stivhed

Glasfyldt nylon er stivere end almindelig nylon og bøjer ikke, når det udsættes for tryk. Det gør det velegnet til tandhjul, beslag og mekaniske huse.

Mode og friktionsmodstand

Glasfibre øger også slidstyrken og mindsker dermed sliddet på de bevægelige dele. Komponenternes levetid forlænges ved at bruge sprøjtestøbning af glasfyldt nylon, som især kan anvendes i miljøer med høj friktion.

Letvægt

Selv om det er kraftigt, er glasfyldt nylon betydeligt lettere end metalprodukter, og det bruges derfor i bilkomponenter, rumfart og elektroniske produkter, hvor vægtreduktion er vigtig.

Kemisk modstandsdygtighed

Nylon er glasfyldt og kan modstå olier, brændstoffer og de fleste kemikalier og er derfor velegnet i barske miljøer. Det garanterer holdbarhed i industrien eller i bilindustrien.

Typer af glasfyldt nylon

Glasfyldt nylon har flere typer, der hver især er beregnet til at blive brugt på en bestemt måde i sprøjtestøbning af glasfyldt nylon og sprøjtestøbning af glasfyldt nylon.

Typer af glasfyldt nylon

PA6 med glasfyld

Nylon 6 (PA6), der er forstærket med glasfibre, er stærkt og stift og slidstærkt. Det anvendes mest i industri- og bildele.

PA66 med glasfyld

PA66 (Nylon 66) er mere varmebestandig og har lidt bedre mekaniske egenskaber end PA6. Det vil være perfekt i højtemperaturanvendelser som motorkomponenter eller elektriske huse.

PA6/PA66-blandinger med glasfyld

Blends kombinerer PA6's hårdhed og PA6,6's varmebestandighed, hvilket giver en balance mellem styrke, stivhed og dimensionsstabilitet.

Specialiserede karakterer

Retningslinjer for design af sprøjtestøbning af glasfyldt nylon

Komponenter, der skal bruges i en sprøjtestøbning af glasfyldt nylon, skal designes med stor omhu for at sikre, at komponenterne er så stærke som muligt, præcise og samtidig holdbare. 

Retningslinjer for design af sprøjtestøbning af glasfyldt nylon

Væggens tykkelse

  • Har samme vægtykkelse for at undgå at synke og vride sig.
  • De fleste dele af glasfyldt nylon bør anbefales med en tykkelse på 2-5 m, afhængigt af belastningskravet.

Meget fine sektioner bør undgås, da de kan føre til svækkelse af fiberstrukturen, og tykke sektioner bør undgås, da de kan føre til ujævn afkøling og indre spændinger.

Hjørneradier

  • Skarpe hjørner bør erstattes af afrundede.
  • Spændingskoncentrationen minimeres med en radius på mellem 0,5 og 1,5 gange vægtykkelsen.
  • Sprøjtestøbning af glasfyldt nylon har skarpe kanter, der kan forårsage fiberbrud eller revner.

Rib-design

  • Ribber tilføjer ikke materiale, og de gør produktet stivere.
  • Vedligeholdelse af ribber 50 til 60% på den tilstødende væg.
  • Højden på ribberne må ikke være mere end 3 gange væggens tykkelse, ellers vil der opstå synkemærker og skævheder.

Korrekt ribbedesign forbedrer styrke og dimensionsstabilitet i nylonsprøjtestøbning, der er fyldt med glas.

Boss Design

  • Skruefastgørelserne er lavet med bosser.
  • Har et forhold på tykkelse 1:1 af væggen og fileter i bunden.

Man skal undgå lange, tynde knaster, fordi de kan blive skæve under hærdningen ved sprøjtestøbning af glasfyldt nylon.

Udkast til vinkler

  • Undlad aldrig at lave en trækvinkel, så de let kan skubbes ud af formen.
  • Lodrette vægge skal have et træk på mindst 1-2 grader på hver side.

Ridser, deformation og udtrækning af fibre under afformning kan undgås ved korrekt udformning.

Orientering af fiberfleksibilitet.

  • Glasfibrene i sprøjtestøbt glasfyldt nylon er så orienterede, at de bevæger sig nedad i strømningsretningen, når de sprøjtes ind.
  • Få designdetaljer, så stressbanerne er parallelle og normale til fiberen for at opnå maksimal styrke.

Funktioner, der fører til, at fibrene samles eller forskydes, bør undgås, da de kan resultere i en forringelse af den mekaniske ydeevne.

Krympning og vridning

Glasfyldt nylon krymper også mindre sammenlignet med ufyldt nylon, men uens tykkelse på væggen kan føre til skævvridning.

Varierende vægtykkelse, ribber og utilstrækkelige kølekanaler bør anvendes for at sikre minimal dimensionsvariation.

Overfladefinish

  • Det kan medføre, at overfladen bliver lidt grovere på grund af tilstedeværelsen af glasfibre.
  • Anvend polerede forme eller efterbehandling, hvis en glat finish er meget vigtig.
  • Polér ikke for meget for ikke at forvirre fibrene i sprøjtestøbning af glasfyldt nylon.

Populære komplikationer og løsninger

Selvom den sprøjtestøbte glasfyldte nylon er effektiv, giver den nogle udfordringer:

  • Fiberbrud: sker, når der er for meget klipning i blandingen.
  • Afhjælpning: Juster blandingstiden og hastigheden på opløsningsskruerne.
  • Forvrængning af dele: Dele kan blive forvrænget på grund af ujævn afkøling.
  • Afhjælpning: Finjuster temperaturen i formen og formens design.
  • Overfladernes ruhed: Fibre kan give ujævne overflader.
  • Løsning: Polering af forme og processer.
  • Indtagelse af vand: Nylon absorberer vand, og det påvirker kvaliteten.
  • Løsning: Før støbning skal materialerne fortørres.

Producenterne vil være i stand til at udnytte det maksimale af glasfyldt nylon ved at løse disse problemer.

Hensyn til miljø og omkostninger

I visse tilfælde, hvor der anvendes metaller, er sprøjtestøbning af glasfyldt nylon mere miljøvenligt:

  • Mindre energiforbrug: Lettere materialer vil minimere energiforbruget i produktionen.
  • Mindre materialespild: Skrot minimeres ved nøjagtig støbning.
  • Forlænget produktlevetid: Holdbare dele kræver færre udskiftninger og har derfor en lav miljøpåvirkning.

Der er også fordelen ved at sænke omkostningerne gennem øget hastighed og mindre spild, hvilket betyder, at sprøjtestøbning af glasfyldt nylon vil være et gunstigt valg i den store produktion.

Bedste praksis fra producenterne

De bedste metoder til at gøre brugen af sprøjtestøbning med glasfyldt nylon vellykket omfatter:

  • Tør de fortørrede materialer af for at undgå fugtrelaterede defekter.
  • Jævn fiberfordeling Brug passende skruedesign.
  • Maksimer temperaturen i formene og indsprøjtningshastigheden.
  • Kontrollér afkølingen af skærmen for at sikre, at den ikke er skæv.
  • Der bør anvendes overflader af højkvalitetsforme.

Det er ved at følge denne praksis, at man opnår ensartede dele af høj kvalitet med fremragende ydeevne.

Fremtidige tendenser

Anvendelsen af sprøjtestøbning af glasfyldt nylon er stigende på grund af:

  • Større behov for letvægtsdele til biler.
  • Forbrugerelektronik har høj ydeevne. Varmebestandige komponenter, der bruges i industriel automatisering.

Der forskes stadig i at kunne justere fibrene bedre, sænke cyklustiden og øge den tid, hvor dette materiale kan genbruges, så det kan blive endnu mere fordelagtigt i fremtiden.
