Product details

We focus on providing Customized motor housings solutions for global washing machine manufacturers and high-end home appliance brands. Our core products include SPHD black power coating motor housing cover, which are made of SPHD cold rolled steel plate (thickness ≥1.2mm) as the base material, with high temperature sprayed epoxy resin and carbon fiber reinforced coating on the surface, forming a protection system with high strength, corrosion resistance and heat dissipation optimization. The products have passed IP68 waterproof and dustproof certification and RoHS environmental protection testing, and are suitable for direct-drive motors, dual-speed motors and other models, supporting customization needs from small household washing machines to industrial-grade large-scale dewatering equipment, with an annual production capacity of 500,000 sets, and a shortened delivery cycle of 15 days.

Advantageous features: redefine the performance boundary of motor housing
