Our integrated approach combines advanced die-casting technology with environmentally friendly powder coating processes to deliver components that meet stringent quality standards while maintaining competitive pricing for bulk quantities.

Material Selection and Performance Characteristics

We specialize in aluminum die-casting alloys including ADC12, A380, and A360, chosen for their exceptional casting characteristics and mechanical properties:

• ADC12 Aluminum: Silicon content 10.5-12.0%, copper 1.5-3.5%, tensile strength 280-320 MPa, excellent fluidity

• A380 Alloy: Tensile strength 324 MPa, yield strength 159 MPa, elongation 3.5%, good machinability

• A360 Aluminum: Superior corrosion resistance, tensile strength 317 MPa, pressure tightness

These materials demonstrate excellent dimensional stability, good thermal conductivity (96-140 W/m·K), and natural corrosion resistance, providing ideal substrates for powder coating applications.

Advanced Die-Casting Manufacturing Process
