Precision Metal Stamping: Products and Materials

YAMAGEN (THAILAND) manufactures various precision metal-stamped components, particularly automotive electrical connectors and terminals, as well as leaf springs and motor components.

Supported materials include phosphor bronze, tough pitch copper, brass, oxygen-free copper, stainless steel, iron, nickel, aluminum, and duralumin.

The typical material thickness range for precision stamping is approximately 0.04–2.0 mm. The company has experience processing ultra-thin materials at the 0.04 mm level. Manufacturing feasibility is evaluated based on component geometry, material properties, and required precision.

Die Design and Manufacturing to Mass Production

YAMAGEN (THAILAND) provides an integrated production system covering die design and manufacturing, precision metal stamping, mass production, and die maintenance in Thailand.

The company can perform die adjustments and improvements locally when dimensional changes or variations in stamping conditions occur during mass production. This capability supports stable manufacturing of high-precision components such as connectors and electrical terminals.

Ultra-Thin Metal Processing at 0.04 mm

YAMAGEN (THAILAND) has experience in precision stamping automotive leaf springs using SUS304CSP-H stainless steel with a thickness of 0.04 mm.

Processing ultra-thin materials requires highly accurate dies and precise adjustments. The company applies its accumulated expertise in precision stamping and die adjustment to support mass production of thin and ultra-thin metal components.

In addition to electrical terminals and connectors for automobiles and motorcycles, the company has manufacturing experience with home appliance components and welcomes inquiries regarding various applications involving thin metal materials.

Sub-Assembly and Gold Spot Plating

In addition to supplying individual precision-stamped components, YAMAGEN (THAILAND) supports sub-assembly services by assembling stamped metal parts with resin components or other parts according to customer requirements.

The company has experience delivering long busbars assembled with resin components to help prevent deformation during transportation. Assembly and delivery methods can be proposed based on component geometry and intended applications.

For gold spot plating, the company works with partner manufacturers to apply gold plating only to required areas, such as electrical contact points. Compared with full-surface plating, this approach reduces gold consumption while maintaining the necessary functional properties.

Production Equipment and Quality Control

The Thailand factory is equipped with automatic stamping presses manufactured by YAMADA DOBBY and AMADA, along with other production and inspection equipment for precision metal components.

The factory is also equipped with servo feeders to support its production processes.

The company holds ISO 9001:2015, ISO 14001:2015, and IATF 16949:2016 certifications.

Quality control covers manufacturing, inspection, packaging, and shipment. The company operates with a target defective delivery rate of 0.2% or less, measured by the number of deliveries, supporting consistent quality in mass-produced components, particularly for automotive and motorcycle applications.
