We also accept consultations! Precision parts can be pressed and assembled all at once! We can handle intricate parts that are difficult to incorporate with automatic machines, as well as achieve short delivery times and cost reductions.

The term "composite mold (progressive die)" refers to a mold that allows for simultaneous press processing and assembly, enabling the speedy and large-scale production of high-quality parts. We specialize in the design and manufacturing of such composite molds (progressive dies). These molds can accommodate intricate parts that are difficult to integrate into automated machines and have traditionally relied on manual labor, contributing to significant reductions in process time, labor costs, equipment expenses, and CO2 emissions. We have extensive experience in industries such as telecommunications, electronics, electrical equipment, and automotive, where product complexity is increasing. We welcome inquiries like, "I want to create something like this..." Please feel free to contact us anytime. 【Strengths】 - Achieving short delivery times and low costs - Completing assembly within the mold for products that involve multiple processes - Making possible processes that are difficult with conventional pressing - Contributing to material reduction by decreasing pitch through simultaneous press and tapping processing - Obtained Panasonic's "EX Passport" in December 2015 *We are currently offering business introduction materials and documents featuring improvement case studies. You can view them immediately via the download button.
