Design and Manufacturing Metal Dies

Manufacture and assembly of precision dies

We also produce metal precision dies. Integrated production is possible. We will accommodate your needs from prototypes to mass production.

Die design and molding

In addition to injection molding we also offer designing and developing of special structure dies and hot runners.

Die maintenance

We carry out maintenance within our own company. In any cases of trouble, we will resolve it promptly.

Measurement and Testing

We have various measurements to stabilize the quality of our products. Testing criterias will be set accordingly to necessary structures and elements.

1 Level 2 QC
7 Level 3 QCs present

Extensive measuring equipment

We have a dedicated inspection room where we conduct various and thorough inspections using instruments such as image measuring machines, CNC three-dimensional measuring machines, roundness measuring machines, gear meshing test machines, etc.
We only deliver products that have passed the inspection and meets environmental standards.
We also accept inspection and measurement orders.

Surface Treatment / Micro Blasting

We implemented a micro-blasting machine by IEPCO for washing machine screws, improving mold releasabilities, maintenance of molds, etc, to improve productivity.
