Injection Mold-Making Process

Modern manufacturing depends on injection mold making to produce many plastic parts at high quality. A mold maker creates the tool by developing the mold design and then processing it into a testable shape for molten plastic products. A reliable Chinese injection mold maker follows established steps to produce molds that work well and save money.

1. Product and Mold Design

Product designers at the start of mold-making develop a complete 3D model of the plastic part for engineering purposes. The final product design determines how the mold will be created.

• The part’s dimensions, material, and production volume.
• The number of cavities (single-cavity or multi-cavity molds).
• Our system includes ways to cool and push out molded parts effectively.

Mold design optimization becomes easier through advanced CAD and CAE software systems. Experienced plastic mold maker China companies examine mold flow patterns to find any production issues in advance.

2. Mold Material Selection

The selection of suitable mold materials directly affects how well your product will work and stay intact. An experienced injection mold maker in China works with these standard mold materials:

• Hardened Steel serves best for production lines that create many parts because it stays strong under heavy use.
• Pre-Hardened Steel: Easier to machine but suitable for medium production runs.
• Aluminum provides an economical solution for prototype making and small batch production due to its lightweight properties.

The mold selection process depends on production needs, plastic type ,and how long the mold needs to last.

3. CNC Machining and EDM Processing

After approving the mold design our production team uses advanced machines to start manufacturing.

• The CNC System controls the precision cutting of metal blocks through Computer Numbered Control for industrial production.
• The EDM machine generates intricate details through electrical sparks that CNC machines cannot match.

The top mold manufacturer in China uses their experience to machine every mold part perfectly which decreases the chance of product defects in the finished plastic parts.

4. Heat Treatment and Surface Finishing

Applying heat treatment strengthens the metal parts to make the mold more durable and effective. The heat treatment process makes the mold parts stronger and better able to withstand production cycles.

The mold gets final processing through surface treatments after heat treatment.

• Polishing: Creates a smooth, high-quality finish.
• Texture: The molding process includes texturing operations to add specific surface designs to finished plastic items.

5. Mold Assembly and Fitting

All mold parts that have been machined and treated are put together to make a finished mold system. This includes:

• The mold system contains both the plastic forming tools core and cavity units.
• The molded product can be taken out through ejector pins.
• The system includes channels that control mold temperature and speeds up production cycles.
• The guide pins and bushings help the mold parts stay correctly aligned during production.

Mold fitting needs to be done correctly to produce quality results during injection molding. Specialist engineers from China’s professional injection mold-making company check and refine each mold part until it fits perfectly.

6. Mold Testing and Trial Runs

The mold manufacturer tests the mold using initial injection molding operations ahead of starting regular production. This step ensures that:

• The mold proves its ability to work properly without any issues.
• The plastic components match quality requirements for size, surface quality, and material strength.
• Manufacturers make necessary changes to enhance product quality before starting mass production.

Plastic mold maker China companies test molds with various plastic materials during trials to check their performance and production effectiveness.

7. Mold Modifications and Final Approval

Our team makes required changes when testing finds problems with performance or operations. These may include:

• The cooling system needs adjustments to remove heat better.
• The mold maker adjusts the ejector pin positions to make part removal easier.
• We improve the cavity surface by smoothing or reshaping the mold parts.

After the mold meets all quality standards during inspections it becomes ready for large-scale manufacturing.

8. Mold Delivery and Production Start

The approved mold travels to the injection molding facility where production workers install it into an injection molding machine. A top-tier Chinese mold maker supplies technical help and maintenance guidelines to keep your mold running well into the future.

The Factors that Affect the Costs of Injection Molding

The cost of plastic molds and plastic injection molded parts is an important factor that determines the overall success of a manufacturing project. There are several things that affect the injection molding costs; part complexity, size, surface finish, material selection, mold cavities and production volume. This can be studied by businesses to optimize their designs and cut down on the expenses to engage with professional mold manufacturers.

Complexity of the Design

Mold manufacturing costs depend directly on the complexity of a component. More advanced tooling, required engineering, additional processing, contribute more toward a higher mold price. In order to minimize costs additional, unnecessary features, sharp angles and details should be simplified where possible. If some of the design can be kept simple, the part can be very cost effective without sacrificing its function.

Size of the Component

Naturally, a larger component requires a larger mold, which in turn uses more raw material and machining time. The total cost increases with the increase in the mold size. In the case of injection molded parts, one of the essential aspects of designing is that the size of the part can be optimized without affecting the performance. Reducing unnecessary bulk (in this example, reduction of vanilla pods) can help lower production costs with product integrity.

Choice of Material

Material and mold costs are strongly affected by the type of plastic that is used in the molding process. Such plastics like reinforced or high performance polymers have higher cost because of their durability and specialized properties. In addition, if abrasive or heat resistant plastics are used, such as hardened steel are required to withstand wear and as a consequence you increase the overall cost. It’s important to select a material that is of good quality but which won’t break the bank on performance.

Surface Finish Requirements

Molded part surface finish will affect part aesthetics as well as part cost. Manufacturers have the option of a lower grade finish, SPI Finish B-3, or C grade finish for the component not being part of the visible part of the final product. But if a nice, kind of nice quality finish is what you want, you are going to need to do additional process steps, additional cost, on the production process.

Cavity Count and Production Volume

Consequently, cost considerations are highly dependent on mold cavity configuration. This means that the single cavity mold would be cheaper to make, but the per part costs are higher because production is inefficient. However, multi cavities molds or family molds present a faster run time and a lower per unit cost but higher initial mold cost.

In this case, single cavity molds for small production runs maybe the most cost effective option. Despite that, for large production, multi-cavity molds can significantly lower long term costs through an increase in production output and efficiency.

Methods for Estimating Plastic Injection Molding Costs

When planning an injection molding project, depending on what manufacturers provide for pricing may not provide a complete picture of how a project might really cost. There are many ways to estimate plastic injection molding cost behaviours to help businesses make a better decision. There are following methods which help in calculating the expenses for different production volumes in an organized manner.

Low Volume Injection Molding Cost Estimation 

Feature-based cost estimation is quite effective for small-scale production. The cost of mold influences the price of this part greatly, therefore for this part, low-volume injection molding often uses rapid tooling techniques to quickly have the mold produced so that a small number of molds can be produced.

Material prices are estimated accurately according to the part’s geometry shape and the design requirements. As well, the right injection molding machine must also be selected from a database with a column of available machines that will optimize cycle time based on component geometry, material properties, and machine specifications.

Another important step in the cost estimation is the choice of a mold base. Standard mold sizes from well known mold suppliers can be used to select the most efficient mold configuration. When the manufacturing and cost of material are calculated for different cavity arrangements, the most economically feasible arrangement can be determined.

Feature-Based Cost Estimation for Mass Production

A feature cost estimation method is best for high-volume manufacturing. Due to the large number of units manufactured in a given production run, mold expense is spread over higher numbers of units and more durable, high-precision molds can be used, even though they are more expensive upfront.

Based on current raw material prices, estimates of material costs are made based on part geometry. Another factor is selection of the most appropriate injection molding machine in order to reduce the production expense also to shorten cycle time.

The mold base needs to be selected using the sizes and categories of standard mold to be able to calculate mold expenses. Immediately thereafter, the needed mold setup is worked out according to part geometry and production requirements. Mathematical evaluations of multiple cavity configurations allow businesses to determine the most cost effective cavity that combines material, manufacturing and mold costs.

Plastic Mold Cost Estimation

The cost of manufacturing the mold itself might also be determined using another cost estimation method based on features. Part dimensions and required features such as cavities count should dictate the intent standard mold size. Processing requirements and overall price depend on the type of mold, the SPI standard mold or the rapid-prototype type for low-volume production.

A quick mold manufacturing approach can be used to produce molds within shorter timeframes which can shorten the lead time of low-volume products. But in the case of mass production high-precision molds made for durability will turn out to be a less costly option at a later time.

Average Cost Estimation Approach

An injection molding cost calculator will give a basic idea of what an injection molding job would cost without part geometry. Additional process parameters, such as material selection, runner count, number of components, etc, are also needed for this method of stepwise process transition.

A pricing database will help deduce the material cost of parts but customizable parameters like cycle time, machine rates and labor cost will breakdown production expense. A detailed cost summary of materials, manufacturing, and mold production is generated once mold costs are taken into consideration, and it helps firms to plan their budget in a very systematic manner.
