Thermoset Mold Design & Manufacturing
Wenzhou Jintong has specialized in thermoset mold design and manufacturing for over 20 years. We produce compression molds, injection molds, and are proficient in advanced technologies including automatic de-gating, cold-runner, and runner-less systems.
Our tooling engineering team provides full support from product design review to final mold qualification. We work with Pro/E, SolidWorks, 3D CAD, and can read DWG, DXF, IGES, STEP, and STL files.
Manufacturing Capabilities at a Glance:
Mold Core Material: 2344 (H13) or 5CrNiMo steel, vacuum-quenched to ≥HRC 58.
Machining Precision: 5-axis CNC machining. Cavity tolerance: ±0.02 mm. Parting surface flatness: ≤0.03 mm.
Surface Finish: Mirror polishing to Ra ≤0.1 μm, with optional PVD coating (CrN or TiAlN) for extended mold life.
Mold Trial: Every mold undergoes a 100-shot trial run. Standard acceptance criteria: fill rate ≥98%, demolding success rate ≥99.5%, dimensional stability per ISO 2768-mK.
From material selection (2344/H13, SKD61) and CNC machining to final assembly and quality inspection, we manage the complete mold manufacturing chain. This ensures our customers receive molds that deliver consistent part quality from shot one.
