Products and Technologies

Strengths – quality control capability and on-time delivery

Expertise built up over many years to satisfy customers

Example: Precision stamped products

●Specializes in manufacturing precision stamped products with complex shapes

This is the result of more than 30 years' experience in meeting the quality and delivery requirements of major consumer electronics manufacturers, and is the result of long-standing expertise.

Sheets of SUS, brass, aluminum, phosphor bronze, plated steel, and other materials with thickness of 0.1 to about 3 millimeters can be stamped.

Stamped products with a mixture of various stamping processes

●Diverse press operations supported with ease

Punching, bending, and burring are naturally possible, and even pressing process prone to cracking and folding is realized fault-free. Multi-process machining is streamlined by assembling single-shot presses into production lines.

KOMATSU is particularly good at multi-process stamping and manufacturing high-precision components.

Proposal-oriented company providing joy and trust to its customers

Proposal of adequate materials, processes, and costs

Example: Proposed press products

●Good products emerge from tuning in to customers’ needs, presenting, and negotiating.

KOMATSU listens carefully to customers’ valuable ideas and opinions, and then suggests adequate materials, methods and processes, costs.
It proposes dies to reduce multi-processes, thus contributing to cost saving and delivery time shortening to provide trust and satisfaction to customers.

Perforated metal composite stamped parts

●Fully supportive of unit ordering.

KOMATSU provides post-processes like tapping and swaging as well as welding, surface treatment (plating, coating, printing) and decoration, either in house or in collaboration with neighboring partner factories.
To meet prototype requests from customers who have no drawings or are in a hurry, KOMATSU has sufficient technological and creative power supplemented by collaboration with partner factories as necessary.

Strict inspection system possible because KOMATSU is a suggestion-based company

A rated quality to pride in

3D measuring instrument

●Presses from 45 to 150 tons are available as well as a strict inspection system
