Home Appliance Mold Manufacturing (Up to 25-Ton Molds)
Export-grade large injection tooling for major white goods, consumer electronics, kitchen appliances, and power tools. Backed by 5-axis gantry CNC machining, 3000T in-house trial presses, and RHCM high-gloss mirror surface technology.
RHCM Steam Dynamic High-Gloss & Surface Engineering
Eliminating spray painting through in-mold mirror finishing, high-temperature steam thermal cycling, and advanced conformal cooling:
RHCM Rapid Thermal Cycling
Cavity surface is preheated to 150°C using pressurized steam before injection, then chilled with water at 15°C, eliminating weld lines completely.
Piano-Black Class-A Polish
ESR electroslag remelted tool steels (S136 / 1.2343 ESR) hand-buffed with diamond paste to SPI A-1 optical mirror finish.
100% Weld-Line Elimination
High surface mold temperature allows converging polymer melt fronts to completely fuse, eradicating visible knit lines.
Rapid Chilled Water Quenching
High-flow 10°C chilled water circuits rapidly solidify the part immediately after cavity packing, locking in cycle time.
Eco-Friendly Paint Elimination
Achieve flawless SPI A-1 piano-black and high-gloss finishes straight from the mold, eliminating painting VOC emissions and scrap.
