Engineering Validation & DFM Analysis
Successful molding begins with engineering validation. Before tooling release, our engineers perform detailed DFM analysis and feasibility evaluation.
- Product structure and functional analysis
- Material behavior evaluation for PMMA, PC, and engineering plastics
- Risk identification for warpage, sink marks, and optical distortion
Engineering-Driven Mold Design Approach
Our mold designs are engineered for stability and repeatability, not just dimensional accuracy on drawings.
- Mold structure optimization for durability
- Cooling layout design for thermal balance
- Process-focused design for long-term production stability
Mold Flow Analysis & Process Simulation
Mold flow analysis is applied to optimize gating, runner layout, cooling balance, and filling behavior before machining begins.
- Reduced trial-and-error during mold testing
- Early detection of filling imbalance and air traps
- Improved surface quality and dimensional consistency
Precision Mold Manufacturing Capability
All molds are manufactured in-house using precision CNC machining, EDM processing, and optical-grade polishing.
- CNC machining for complex mold structures
- EDM for fine and optical features
- High-polish cavities for optical clarity
Mold Steel Selection & Performance
Proper mold steel selection directly impacts mold life, surface quality, and production consistency.
- S136 stainless steel for optical-grade finish
- NAK80 steel for excellent polishability
- Pre-hardened steels or aluminum for prototyping
Cold Runner & Hot Runner Mold Solutions
We design both cold runner and hot runner molds based on production volume, material usage, and cost targets.
- Cold runner: lower initial tooling cost, flexible adjustment
- Hot runner: reduced material waste, faster cycle times
- Balanced system design for stable mass production
Prototype, Quality Control & Production Readiness
In addition to mass production molds, we provide flexible tooling solutions for small batch and prototype molding.
- Dimensional inspection and surface quality verification
- Trial molding and process validation
- Documentation for long-term production tracking
