Technical FAQ

Q: How do you handle the venting issues in injection mold components?

A: We provide specialized venting pins and porous metal inserts that allow gas to escape while preventing flash, significantly reducing gas burn defects in plastic parts.

Q: Can you manufacture custom components according to our 3D CAD files?

A: Yes, we specialize in non-standard components. We can process STP, STEP, or IGS files and maintain tolerances as tight as 0.002mm for custom cores and cavities.

Q: What is the recommended maintenance for moving mold parts?

A: We suggest regular inspection of lubrication channels. For cleanroom applications, we provide DLC-coated or self-lubricating graphite components that operate without oil to prevent product contamination.
