Companies in China's metal stamping sector are investing in advanced equipment to realize tighter tolerances.

For precision-made parts for automotive and robotics applications, home appliances, electronic products, computers and machineries, metal stamping manufacturers in China aim to achieve ±0.001mm tolerance in the near future. They have been introducing equipment such as lathes, and laser-cutting, welding and CNC machines toward this end. Dongguan Tangxia Shuangxin Hardware Products Fty, for instance, has acquired 250-ton lathes to turn out high-precision and large pieces.

In general, companies underscore capability to handle any material. They usually adopt copper, aluminum, steel, stainless steel and metal alloy, but can also process zinc and titanium when required.

For surface treatment, makers offer anodizing, powder coating, passivation, and plating with zinc, chrome, tin, silver and gold. Typical releases are 0.1 to 6mm in thickness and have 0.01 to 0.05mm tolerance.

Manufacturers source materials from local suppliers.

The cost of production inputs did not change much in 2018 so most companies maintained their prices. The same trend is expected until end-2019.

The products in this gallery have been handpicked by our market analyst for representing current trends in stamped metal parts from China makers.
