Custom Plastic Molded Parts Manufacturer for OEM Applications
Precision injection molded plastic components for automotive, electronics, medical, industrial, and consumer products.


What is Plastic Injection Molding?
Plastic injection molding is a highly versatile manufacturing process that produces custom plastic parts by injecting molten plastic material into a precision mold. This process enables mass production of identical components with complex geometries, tight tolerances, and consistent quality.
The standard workflow includes five core steps:
- Plastic pellet melting and homogenization
- High-pressure injection into mold cavities
- Complete cavity filling and packing
- Controlled cooling and solidification
- Part ejection and post-processing trimming

Injection Molding vs. CNC Machining for Plastic Parts
Choosing the right manufacturing process depends on your production volume, part complexity, and cost requirements. Here’s how they compare:
Frequently Asked Questions
What plastics are commonly used in injection molding?
We work with a wide range of materials including ABS, PC, PA/Nylon, POM, PEEK, PP, PE, and many more. We can help you select the best material based on your part’s performance requirements, environment, and budget.
What tolerance can your injection molding achieve?
Our precision molding capabilities allow us to achieve tolerances as tight as ±0.01 mm for critical components, with standard tolerances ranging from ±0.01 mm to ±0.05 mm depending on part size and material.
How long does injection mold tooling take?
Standard mold lead time is 2-5 weeks, depending on the complexity of the part and mold. For urgent projects, we can offer expedited tooling services to meet your timeline requirements.
What is the difference between ABS and PC plastic?
ABS offers good impact resistance and machinability at a lower cost, making it ideal for general-purpose parts like enclosures. PC provides higher strength, heat resistance, and transparency, making it better for safety-critical or high-temperature applications.
Do you offer DFM analysis for my design?
Yes, we provide free DFM (Design for Manufacturability) analysis for all new projects. Our engineering team will review your CAD file, identify potential manufacturing issues, and provide recommendations to optimize your design for cost and quality.
