Custom electrical and auto parts plastic injection mold molding services

The dimensional repeatability of injection molded products is very high, and the accuracy is usually 0.01 ~ 0.001mm.

Injection mold design and mold manufacturing requirements are very high, and manufacturers with rich experience in precision plastic injection molding can be competent.

Plastic raw materials used for plastic molding manufacturing must meet the following requirements:
High mechanical strength, stable size, good creep resistance, a wide range of environmental adaptation.

Plastic Injection Molding

Plastic injection molding is a versatile manufacturing process that utilizes high-pressure injection of molten plastic into a mold cavity to produce a wide range of complex and durable plastic products. This is an ideal process for producing large volumes of standardized parts with excellent mechanical properties.

Insert Molding

Insert molding involves the injection of molten thermoplastic around a pre-placed insert to create strong, durable parts. This technique offers advantages like reduced assembly time, improved product reliability and the ability to combine multiple materials in a single part.

Overmolding

Overmolding is a process in which multiple shots of thermoplastic are injected over or around a substrate to create highly customizable parts. This technique offers versatility and customization options, allowing for the creation of complex and multi-material products with enhanced performance and visual appeal.

Micro Molding

Micro molding is a specialized variation of the injection molding process used to produce small parts with complex geometries. This process allows for the creation of extremely small shot weights, making it a popular option for medical devices, electronics and automotive applications. Micro molding can produce components as small as 0.00025 cc with high quality and repeatability and is compatible with a variety of materials such as PEEK, ABS, Pebax and polypropylene.

Repeatability

In the automotive industry, repeatability - or the ability to consistently produce the same parts - is critical. Because automotive plastic injection molding typically relies on sturdy metal molds, the final molded automotive parts produced using molds are virtually identical. Some factors can affect injection molding, but if the mold is well designed and finished, injection molding is a highly repeatable process.

Material Availability

A significant benefit of using injection molding for automotive production is the wide range of rigid, flexible, and rubber plastics the process is compatible with. Manufacturers use a wide range of different polymers for various applications in the automotive industry, including ABS, polypropylene, acrylic, acetal, nylon, polycarbonate, and more.

High precision and surface finish

Injection molding is ideal for the production of plastic parts with relatively simple geometry and high surface finish. Manufacturers have many surface treatment options when producing parts, including a variety of surface textures - such as smooth, rough or matte - that are applied directly to the mold rather than the molded part. However, different plastic materials can also affect the final surface finish.

Rapid prototyping and quick tools

Although injection molding is widely used by automakers to mass-produce auto parts, they also use it as a prototyping tool. With rapid mold manufacturing fast, low-cost aluminum molds - usually through additive manufacturing or CNC machining - automotive mold manufacturers can complete short-term production of prototype molded automotive parts much faster than traditional (steel) molds.
