FAQ
Q: Why choose a cold runner system over hot runner?
A: Cold runner systems are generally more cost-effective for certain volumes and are easier to maintain, making them ideal for many electronics parts.
Q: Can you achieve a high-gloss finish without post-processing?
A: Yes—polished mold cavities and precise processing ensure smooth, glossy surfaces straight from the mold.
Q: Which plastics work best for smooth surface finishes?
A: ABS, PC, and PMMA are excellent for glossy finishes, while PP and PA can also achieve smooth results with proper tooling.
Q: What’s the minimum order quantity?
A: Standard MOQ is around 500 units, but we can accommodate smaller runs for prototypes.
Q: Are your materials RoHS compliant?
A: Yes, we can provide RoHS-compliant materials upon request.
Q: How do you ensure surface quality?
A: Through precision tooling, controlled molding parameters, and thorough visual inspections.
