Precision Progressive Die Stamping and Applications

Precision progressive die stamping is a manufacturing process in which metal strip material is fed sequentially through a die to perform multiple operations, including punching, bending, and forming. It is well suited for mass production of precision components such as connectors and electrical terminals.

YAMAGEN (THAILAND) manufactures connectors, terminals, and leaf springs primarily for automotive and motorcycle applications, as well as motor-related components.

For thin metal components, die accuracy and adjustments based on material properties are essential. By managing die manufacturing, stamping, and ongoing maintenance, the company supports stable, continuous production.

Material Thickness and Supported Materials

YAMAGEN (THAILAND) handles material thicknesses of approximately 0.04–2.0 mm for precision metal stamping.

The Thailand factory has experience manufacturing automotive leaf springs using 0.04 mm thick SUS304CSP-H stainless steel.

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

The stated thickness range is a general guideline. Manufacturing feasibility is assessed individually based on material type, component geometry, and dimensional tolerances.

Mass Production with 31 Automatic Stamping Presses

The Thailand factory operates 31 automatic stamping presses manufactured by YAMADA DOBBY and AMADA, with capacities ranging from 8 to 60 tons.

The facility operates on a 24-hour production schedule and is also equipped with eight single-action hydraulic presses, two precision roll levelers for thin metal sheets, and eight servo feeders.

Equipment is selected according to component geometry, material, and required production volume to support stable mass production in Thailand.

Die Design, Manufacturing, and Maintenance

Precision progressive die stamping of thin metal sheets requires tight punch-to-die clearances, accurate tooling, and precise adjustments.

YAMAGEN (THAILAND) provides die design, manufacturing, and precision stamping at its Thailand factory. Local technicians also handle die component manufacturing, replacement, adjustment, and maintenance during mass production.

These capabilities allow the company to respond to changes in die conditions and stamping parameters, supporting consistent production from initial die preparation through ongoing mass production and maintenance.

Inspection Equipment and Quality Control

Precision stamping requires reliable dimensional inspection as well as accurate production equipment.

The Thailand factory uses a KEYENCE IM-6120 image dimension measuring system, Nikon profile projectors, and Nikon 3D industrial microscopes to inspect component dimensions and geometry.

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

Quality control covers manufacturing, inspection, packaging, and shipping, with a target defective delivery rate of 0.2% or less, calculated by the number of deliveries.

Drawing on its experience in automotive and motorcycle components, the company focuses on dimensional accuracy and consistent quality in mass production.
