Stage 01
Product Structure & Mold Feasibility.
Every mold begins with careful engineering review. We analyze product geometry, wall thickness, draft angles and parting lines to ensure manufacturability and perfect demolding.
DFM Analysis
Design · Review · Approve
3D Geometry Review
We evaluate product 3D files, assess wall thickness uniformity, undercuts and curvature complexity.
Draft & Parting Analysis
Optimal parting line placement and draft angle recommendations for smooth demolding without defects.
Food-Grade Validation
Material compatibility review ensuring compliance with FDA, LFGB and infant safety standards from day one.

Stage 02
Mold Solution Design.
Our senior engineers craft tailored mold architectures -- from runner systems and gate locations to cooling channels and ejection mechanisms -- optimized for silicone injection flow.
Cavity Layout Strategy
Single, multi-cavity or family mold recommendations based on production volume and part complexity.
Runner & Gate System
Cold runner, hot runner or cold deck design for liquid silicone -- minimizing waste and ensuring flow balance.
Cooling & Ejection
Precision-engineered cooling channels and ejection pins to maintain cycle time and part integrity.
Stage 03
Mold Materials & Structure.
We select premium tool steels and precision components to guarantee durability, dimensional stability and extended mold life -- essential for silicone's demanding thermal cycles.
Mirror Steel S136
High corrosion resistance, perfect polishability for transparent silicone parts.
Pre-hardened NAK80
Excellent machinability with uniform hardness, ideal for mid-volume production.
Tool Steel P20
Cost-effective for standard silicone molds with reliable dimensional stability.
Hardened H13
Premium heat-resistant steel for high-volume LSR production, 1M+ shots.

Stage 04
Mold Processing & Manufacturing.
Our in-house workshop combines CNC machining, EDM, wire-cutting and precision grinding -- manufacturing molds with micron-level accuracy and consistency.
CNC Machining
5-axis precision milling for complex contours and cavity profiles.
EDM Processing
Electrical discharge machining for fine details and sharp inner corners.
Wire-cutting
Slow-wire EDM for ejector holes, inserts and precision contours.
Mirror Polishing
Hand polishing to Ra 0.025 for food-grade silicone finish quality.
Stage 05
First Trial & Sample.
The first shot validates every design assumption. We produce T1 samples with full documentation -- process parameters, visual inspection and dimensional reports.
Trial Shot
Initial injection to verify flow pattern, filling, venting and demolding behavior.
- ✦Process parameter log
- ✦Visual defect check
Dimensional Report
Full CMM measurement against product drawings and tolerance requirements.
- ✦CMM / caliper check
- ✦Deviation analysis
Sample Delivery
Approved T1 samples shipped to customer with complete process documentation.
- ✦Packaged safely
- ✦Shipped within 7 days
Stage 06
Issue Analysis & Mold Modification.
Every detail matters. Our engineering team identifies root causes of defects and executes precise mold modifications -- iterating until perfection is achieved.
Flash & Burr Defects
Root cause analysis of parting surface, venting and clamping pressure adjustments.
Short Shot & Bubbles
Venting optimization, gate resizing, and injection speed/pressure recalibration.
Dimensional Deviation
Cavity re-machining, shrinkage compensation and precision polishing adjustments.
Surface Quality
Weld lines, flow marks and texture issues addressed through polishing & texturing.
Iterative Refinement Guarantee
Up to 3 rounds of free mold modification are included to meet customer sample approval standards.
