P20 vs H13 Mold Steel: A Complete Comparison for Injection Mold Design
P20 vs H13 Mold Steel is one of the most important comparisons in injection mould manufacturing, helping engineers and buyers choose the right mould steel based on performance, cost, tool life, and production requirements. Composition, hardness, machinability, and application differences between P20 and H13 tool steel — and how to choose the right one for […]
Plastic Injection Mold Polishing Standards Explained
Plastic Injection Mold Polishing Standards play a vital role in achieving high-quality surface finishes, improving part appearance, and ensuring consistent performance in injection moulding. Mold polishing determines how a molded part looks, how easily it releases from the tool, and how long the cavity surface survives repeated production cycles. Yet polishing is frequently treated as […]
Plastic Injection Mold Repair and Refurbishment Guide
A practical engineering reference for tooling managers, maintenance teams, and molders on diagnosing mold wear, selecting the right repair technique, and deciding when refurbishment makes more sense than replacement. Every injection mold degrades with use. Repeated clamping cycles, thermal cycling, abrasive resins, and routine handling gradually wear cavity surfaces, loosen guided components, and fatigue steel […]
