At Sekiguchi Manufacturing, we mainly develop and manufacture production equipment, focusing on precision molds, film punching molds, and press machines. In mold manufacturing, we offer a consistent contract processing service from design to machining, inspection, and shipping. We also provide "QDC molds" that can be produced in as little as three days from order. Additionally, we have numerous achievements in equipment development using transport devices and cameras. We support problem-solving from various angles, including cost reduction, quality improvement, and labor saving. ★ We are currently offering a "Technical Case Study Collection for Problem Solving" available for PDF download. You can view examples of contract processing, mold manufacturing, and equipment manufacturing. 【Table of Contents for the Technical Case Study Collection (Excerpt)】 ■ I want to conduct processing tests on materials ■ I want to reduce personnel costs for product inspection ■ I want to reduce scrap during press processing ■ I want to perform high-precision press processing ■ I want to prevent small debris from adhering during product processing, among others.
