How Plastic Injection Molding Contract Manufacturing Works?

The process begins much before production commences. Successful contract manufacturers will usually adhere to a number of key steps.

Product Design Evaluation

Manufacturer’s review of client’s design and specification. Engineers examine geometry and material specifications, and feasibility for manufacturing. Suggestions may be made for the design to enhance moldability and/or lower production costs. This step is sometimes referred to as Design for Manufacturability (DFM). It is useful for pinpointing potential problems prior to tooling.

Selectarea materialului

It is important to choose the correct plastic material. Various properties are required for various applications.

Common materials include:

• Polipropilenă (PP)
• Polietilenă (PE)
• ABS
• Policarbonat (PC)
• Nylon
• Acrilic
• PEEK
• PVC

The properties of each material are different including strength, flexibility, heat resistance, chemical resistance, etc. The manufacturer is involved in the selection of the appropriate material for the application.

Proiectarea matrițelor și a sculelor

One of the most crucial parts in the injection molding process is the mould. Engineers make a custom mould according to the requirements of the product. The mold will then be produced by precision machining. The expense of moulds might be considerable, however, a quality mould can make hundreds of thousands or even millions of components.

Production Setup

The mold is finished and then put into an injection molding machine.

The production parameters (such as:

• Injection pressure
• Temperatura
• Cooling time
• Cycle time
• Material flow rate

These settings have been optimized to guarantee quality.

Manufacturing Process

Injection Molding Machine: Plastic pellets are added to the machine. The material is melted by heating it up. Under pressure, the melted plastic is forced into the mold cavity. The mold is then cooled, opened and the product is ejected. This process is repeated continually until the production need is satisfied.

Inspecția calității

In plastic injection molding contract manufacturing, quality control is an important aspect. Manufacturers check/inspect parts during manufacturing to verify compliance with specifications.

Inspections may include:

• Dimensional verification
• Visual inspection
• Material testing
• Functional testing
• Surface finish evaluation

This helps in maintaining the consistency of the products as well as satisfaction of the customers.
