Emphasis on equipment to handle any metal stamping requirement

by Vianie Li & Cecile de Veyra

Metal stamping includes tooling, stamping, inner inspection, deburring and cleaning, final inspection and packaging. For these processes, hydraulic punching, drilling, planing and grinding machines are among the key equipment. Some manufacturers also use CNC milling machines and machine tool centers.

In the Chinese mainland, machinery upgrades remain a priority as companies further improve their production techniques and efficiency to boost their capability to handle custom shape, size and tolerance requirements at relatively low costs. Huateng Metal Products (Dongguan) Co. Ltd has introduced advanced CNC machines from Japan, Germany and the Taiwan region and will continue to source production and test equipment overseas in the next two years.

Spurring these improvements is the steady rise in demand. In a report published by Market Reports World, the global market for metal stamping was $143.94 billion in 2020 and is anticipated to reach $169.93 billion by 2027 at 2.4 percent CAGR from 2021.

Widely made stamped metal parts by Chinese companies are made of copper, brass, bronze, aluminum, steel, stainless steel and zinc and are polished, plated, sandblasted, powder-coated, anodized or hot-dip galvanized. These are used in the consumer electronics, communications, automotive, medical and industrial sectors.

To win customer confidence, most Chinese suppliers ensure their products are RoHS-compliant and processed in facilities with certifications based on ISO 9001:2008, ISO/TS 16949:2009 and IATF 16949:2016 standards. They also guarantee fast delivery, accommodate small orders, and offer pre-sale and aftersales services.

Materials used in the metal stamping come from domestic providers. Their costs have increased, prompting manufacturers to raise product prices by 10 to 20 percent in 2021. In 2022, outlay for production inputs may stabilize.
