"In-house production of molds" enhances technical and developmental capabilities,
and enables cost reduction and lead time reduction
Respond to customer requests with mold designed and manufactured in-house by Arai Parts
While many companies outsource the production of dies, Arai Parts has been able to improve its cold heading technology and accumulate know-how over the years by designing dies in-house.
Even with special molds with complicated shapes and mechanisms, we will meet the needs of our customers with the technical know-how we have cultivated.
Mold manufacturing process flow
Equipment introduction
Based on machining analysis using "3D deformation", we design and manufacture dies in-house by making full use of various equipment such as machining, electric discharge machine, and surface grinding machine.
We have various equipment with different characteristics, and it is possible to perform a wide range of processing.
- Relatively easy processing: lathes, drilling machines, milling machines
- Complex and detailed processing: Machining center, electric discharge machine system
Adjustments in micro units (one millionth of a unit) may also be done manually by skilled workers.
