APPLICATION & INDUSTRY SOLUTIONS

Precision Mold Bases for Demanding Mold Applications

🚗 Automotive

Automotive Connector & Sensor Molds

IATF 16949-certified bases for TE Connectivity and Amphenol connector programs — PPAP-ready, critical features to ±0.002 mm.

🩺 Medical

Medical Device Molds

S136H / STAVAX ESR stainless plates with ground mirror faces for syringe and IV-component tools, cleanroom-safe.

🔌 Electronics

3C Electronics & High-Density Connectors

📦 Packaging

Thin-Wall & High-Cycle Packaging Molds

Multi-cavity high-cycle bases with hardened guide systems for caps and closures, rush 24–72 h support.

Key Mold Performance Challenges We Resolve:

Plate Parallelism & Flatness Drift

Double-disc ground A/B plates hold flatness ≤ 0.01 mm / 300 mm so cavity and core inserts seat without shimming.

Guide Misalignment & Mold Shifting

H7/g6 and H7/f7 guide fits with hardened SUJ2 pillars keep the two halves aligned cycle after cycle.

Plate Deflection Under Injection Pressure

Stepped support pillars with H7 shoulder bores plus rigid support plates eliminate deflection and flash.
