Huicheng manufactures precision mold components across multiple product categories. Each product line follows controlled manufacturing routes with verified tolerance capability, material traceability and dimensional inspection.
Precision Mold Inserts
Mold inserts and precision insert components manufactured to controlled drawings. CNC machining, EDM cavity detail, wire EDM profiles, precision grinding and CMM inspection. Standard materials include SKD61, S136, NAK80 and customer-specified steels.
Core Pins & Ejector Sleeves
Ejector pins, core pins, ejector sleeves and custom ejection components. Precision cylindrical grinding for diameter control, heat treatment for hardness, and careful finish control on contact surfaces. Straight pins, angled pins, flat blades and custom profiles.
Sliders, Lifters & Complex Components
Mold sliders, lifter blocks, angle pins, cam slides, gib surfaces and complex multi-component assemblies. CNC machining of gib surfaces and angled cam surfaces, precision grinding after heat treatment, and assembly fit verification. Coordinated tolerance control across mating parts.
Stamping Die Components
Precision stamping die punches, die cavities, stripper plates, guide posts and complete carrier-tape punching dies. Wire EDM for contour cutting, precision grinding for critical fit surfaces, heat treatment to HRC 58–62, and coordinate measurement for punch-to-die clearance.
Plastic mold components
Mold inserts, precision inserts, cores, cavities, core pins, ejector sleeves, sliders, lifters and drawing-specific complex parts.
Stamping tooling
Precision punches, die inserts, progressive-die components and complete carrier-tape punching dies.
Complete mold projects
DFM and design coordination, machining, assembly, mold trial, modification and agreed project documentation.
