Every plastic part has different requirements. Material, wall thickness, tolerance, appearance, strength, assembly method, and production volume can all affect the final result.

That is why we do not treat injection molding as simply putting material into a machine.

At Shun-Tung, each custom plastic injection molding project starts with understanding how the part will actually be used. Our team reviews the product design, structure, material requirements, molding feasibility, and production needs before moving into tooling and mass production.

We work with a wide range of thermoplastic materials, including commonly used engineering plastics such as ABS, PC, PP, PS, and other materials selected according to product requirements.

Our plastic injection molding capabilities are suitable for:

  • Consumer electronic housings and components

  • Automotive interior and plastic components

  • Industrial automation parts

  • Aviation-related plastic components

  • Medical and wearable device components

  • Datacom and telecom equipment parts

  • Custom plastic enclosures

  • Precision plastic components

  • OEM and ODM plastic products

For customers, the goal is simple: produce a part that works properly, fits correctly, looks right, and can be manufactured consistently when production volume increases.
