Aluminium Alloy Die Casting

Aluminium ADC12 | AlSi11Cu3
Introduce:
The ADC12 aluminium is more often used as an alternative for the A380 aluminium for parts that are highly intricate.
Corrosion resistance • Lightweight • Dimensional stability
Aluminium A380 | AlSi8Cu3
Introduce:
The A380 Aluminium gives an excellent combination of machinability, heat transfer and easy casting together with other properties.
Zinc Alloy Die Casting

Zinc Alloy | Zamak 3
Introduce:
The most widely used is Zamak 3 zinc alloy, Good fluidity and mechanical properties. It is applied to castings with low mechanical strength, such as toys, lamps, decorations, and some electrical parts.
Zinc Alloy | Zamak 5
Introduce:
Good fluidity and good mechanical properties. It is used in castings with certain requirements for mechanical strength, such as auto parts, electromechanical parts, mechanical parts, electrical components.
FAQ
Frequently Asked Questions
- What is the SOMI Partner Network?The SOMI Partner Network is a vetted group of specialised manufacturing factories in China, coordinated through one point of contact. Buyers get CNC machining, sheet metal fabrication, metal stamping, die casting, injection molding and 3D printing from one programme, with one engineering review, one quality route and one quotation instead of a supplier per process.
- What does it cost to join the SOMI Partner Network?Nothing is charged to join in either direction. A manufacturing partner pays no membership, listing or subscription fee, and a buyer pays nothing to use the network, only for the parts actually ordered. What does cost money is the work itself: samples, tooling, third-party testing, freight and any audit the buyer requests. Published commission-based sourcing agents charge 3 to 10 percent of order value for comparison.
- How do I join the SOMI manufacturing network?Buyers join in one step: send a drawing and the quotation workflow starts within 24 to 48 hours. Factories join through qualification - document review, an audit and sample validation - which takes two to four weeks for the review and audit, and six to fourteen weeks end to end when custom tooling is involved. Neither track carries a joining fee.
