04 -- Design DFM
Structural Design Requirements.
To optimize moldability and performance, product structure should follow these key design-for-manufacturing principles.
Wall Thickness
Keep uniform wall thickness between 1.0mm - 6.0mm to avoid shrinkage and under-cure defects.
Draft Angles
Add 1°-3° draft on all vertical walls to ensure smooth demolding without tearing.
Rounded Corners
Minimum R0.5mm inner fillets reduce stress concentration and extend mold life.
Parting Line
Place parting lines on inconspicuous edges; flash is natural at these seams.
Textures & Logos
Embossed logos ≥0.3mm height; debossed engravings keep crisp detail.

07 -- Quality
Quality Control Focus Points.
Every batch undergoes multi-stage inspection following ISO 9001 SOPs, ensuring compliance with FDA, LFGB, CE, and RoHS standards.
Visual Inspection
Check color consistency, flash, air bubbles, scorch marks and surface defects.
Dimensional Check
CMM & caliper measurement of critical dimensions to ±0.1mm tolerance.
Physical Testing
Tensile, tear resistance, hardness Shore A, aging & temperature cycling.
Safety Compliance
FDA 21 CFR 177.2600, LFGB §30/§31, EN71 and migration testing.
