Jerry Zou is a CKMOLD technical content contributor and project contact. His editorial scope covers injection mold manufacturing, plastic-part design for manufacturability, material selection, tooling cost, mold trials, production handoff and troubleshooting for international product and sourcing teams.
Editorial responsibility
Jerry’s articles are intended to help product engineers, procurement managers and hardware teams define the information needed before a molding or tooling decision. Technical ranges are presented as starting points and should be checked against the exact resin grade, part geometry, mold, machine and end-use requirements.
Topics covered
- Injection-molded part DFM and CAD release requirements
- Injection mold design, trials, validation and transfer
- Plastic material selection and processing constraints
- Tooling budgets, RFQ preparation and supplier evaluation
- Defect diagnosis and production handoff controls
Evidence and disclosure approach
Regulatory, safety and material-performance claims should be linked to primary sources where available. Hypothetical calculations and illustrative engineering scenarios are labeled as such. No unnamed customer result, reviewer credential or project performance claim should be treated as verified evidence.
