Technology Employed
Transportation machinery/equipment manufacturing industry
Ichibayashi designs utilizing features of forged products and helps to improve integrated forming and strength.
Transportation machinery/equipment manufacturing industry
Ichibayashi performs precision forging based on long years of experience.
Transportation machinery/equipment manufacturing industry
Ichibayashi applies die construction method technology, such as electric discharge machine.
Transportation machinery/equipment manufacturing industry
With milling accomplished via cold-rolled coining, flatness precision and surface roughness requirements are met.
Primary Area of Technical Expertise

Ichibayashi makes products by utilizing the features of forgings based on precision dies using CAD/CAM. The traditional image of small quantity, high die cost, and slow delivery does not apply. Ichibayashi can meet even small-lot orders with short delivery deadlines.

Future Business Challenges
Expansion of, and PR pertaining to, multi-item small-lot forging production that achieves low cost and short delivery deadline
Ability to deliver not only forged completed products but also heat-treated and machined products.
Expansion of products that utilize superiority of forgings (strength, dense structure, wide variety of material types, etc.)
Integration of friction-welded and other composite products through special forging
Reduction of machining costs by machining only portions required
Future Technical Challenges
Transportation machinery/equipment manufacturing industry
Reduction of machining through multi-item small-lot forging.
Transportation machinery/equipment manufacturing industry
Implementation of hot closed die forging of nonferrous metals.
Transportation machinery/equipment manufacturing industry
Use of electric discharge machine to meet mass-production orders.
Transportation machinery/equipment manufacturing industry
Development of composite machinery together with other machines that utilize the superiority of forging.
