FAQ – Precision Injection Molding
What is precision injection molding?
Precision injection molding is a process that produces plastic parts with extremely tight tolerances, consistent dimensions, and high repeatability. It’s essential for industries like medical, aerospace, and telecom.
How does it differ from standard plastic molding?
Unlike regular molding, precision injection molding involves stricter process control, specialized tooling, and high-precision machines to meet tight dimensional requirements.
What materials are best for high precision plastic injection molding?
Engineering plastics like PEEK, PPS, PC, and LCP are commonly used due to their dimensional stability, mechanical strength, and thermal resistance.
Do you support low-volume production?
Yes. We support both prototype and low-volume production for testing and pilot runs, in addition to full-scale manufacturing.
Can you help with design for manufacturability (DFM)?
Absolutely. Our engineers work with your team early in the process to optimize part design, reduce tooling costs, and ensure successful precision injection molding outcomes.
What are the precision injection molding tolerances?
Precision injection molding typically achieves tolerances of ±0.01mm, and in some cases even tighter if part geometry and materials allow. It’s ideal for components that require exact fit, like medical or telecom parts. Consistency and tooling accuracy are key.
What is the accuracy of injection molding?
Injection molding accuracy depends on the process type. Standard molding holds around ±0.05mm, while precision injection molding can reach ±0.01mm or better. Factors like mold quality, material behavior, and machine calibration all influence final part accuracy.
