Manufacturing Excellence
Our micro-feature mold making capability is built on high-speed CNC milling and advanced EDM sinker technology. We use specialized micro-tooling down to 0.2mm diameter and custom-ground graphite electrodes for deep rib EDM. Each micro mold undergoes comprehensive Moldflow simulation before machining to ensure perfect filling of thin-wall sections.
Frequently Asked Questions
Q: What is the smallest feature you can mold?
A: We can achieve molded part features as small as 0.05mm wall thickness with our high-speed CNC and precision EDM technology.
Q: Do you make connectors with 0.4mm pitch?
A: Yes. We manufacture precision connector molds with 0.4mm and finer pin pitch, requiring extreme precision in electrode manufacturing and EDM processing.
Q: How do you prevent short shots in thin-wall parts?
A: We use Moldflow analysis to optimize gate location and size, combined with high injection speeds and precise temperature control to ensure complete filling.
Q: Can you add conformal cooling to micro molds?
A: Yes. We design and machine conformal cooling channels that follow the part geometry, providing uniform cooling for micro-feature parts and reducing cycle time.
