Mainly, molds for the automotive and industrial machinery sectors account for a large part of our achievements, but we also cater to various fields including electrical, aerospace, and chemical industries. Leveraging the knowledge of molds and mold materials cultivated over 60 years of establishment, as well as our business network, we also engage in proposal-based sales to address our customers' concerns. We have various in-house equipment, including 5-axis machining machines, at multiple locations. You can also trust us with quality control. 【List of Our Services】 - Cold/Hot/Warm forging molds (SKD61, SKD11, SKH51, etc.) - Hot stamping (press) molds - Aluminum die-casting molds - Rubber molding molds - Mold materials (other materials are also accepted) - Machining (small to large) - Build-up welding (TIG, plasma, laser, contract and equipment consultation) - Heat treatment (deoxidized, vacuum, salt) - Surface treatment (gas nitriding, ion nitriding) - Coating (TiC, TiCN) - Plating (hard chrome) - Polishing LAP *Regarding heat treatment and surface treatment, we do not have in-house equipment, but we can accept the entire process as a contract. - Shape inspection (non-contact/contact, 3D image camera) - Reverse engineering

Specifically, we capture and analyze the requested item using a "3D image scanner" and prepare it as a 3D model of the mold using modeling software. The imaging accuracy reflects details such as punch marks and engravings, achieving a precision level of several tens of micrometers. Please feel free to consult with us first. As shown below, we provide suitable reverse engineering not only by simply refining the appearance of the model but also by incorporating insights from mold design. 【Case Studies and Features】 ■ In hot forging molds, we have already achieved several models shortly after introduction. (Introduction of scanning equipment: March 2020) ■ In mold processing operations, we mainly receive models from customers for processing, but we possess knowledge regarding "mold models." ■ As a mold material trading company, we also have insights into mold materials and heat treatment, covering the entire field of molds. ■ We have experience collaborating with customers on mold design and mechanical device design. ■ We also have a track record of "design support" as a business to assist with operations. *For more details, please refer to the PDF materials or feel free to contact us.

This document introduces the types and characteristics of alloy die casting, as well as our company's initiatives. "Alloy die casting" is a type of casting method where alloy raw materials such as aluminum, zinc, and magnesium are melted at high temperatures and poured into molds. Our company is engaged in supplying materials (and processing) to casting manufacturers, as well as providing production molds and surrounding tools. Additionally, we carry out comprehensive "mold maintenance," including piping, with dedicated staff. We will respond to our customers' needs by leveraging our "casting mold know-how." [Contents] ■ What is die casting? ■ Types of alloy die casting - Aluminum alloy die casting - Zinc alloy die casting - Magnesium alloy die casting ■ Our company's initiatives in the die casting field *For more details, please refer to the PDF document or feel free to contact us.

Our company provides mold maintenance services. We can handle everything from material procurement to processing and maintenance in a consistent manner! We take care of molds after mass production, performing cleaning, repairs, replacements, and assembly to ensure the molds are ready for the next mass production plan. In "forging die set maintenance," we remove and clean lubricants and release agents used during mass production. We will begin work after consulting with the customer regarding repairs or new replacements. We also accept requests for complete new production. Additionally, we offer "aluminum die-casting mold maintenance" and "equipment jig manufacturing," so please feel free to contact us when needed. 【Features】 ■ Forging Die Set Maintenance - Removal and cleaning of lubricants and release agents used during mass production - Work begins after consulting with the customer regarding repairs or new replacements ■ Aluminum Die-Casting Mold Maintenance - Removal of release agents and adhered aluminum during mass production, and repair by adding material to the mold - Replacement and assembly of parts/hoses - Non-contact measurement of worn areas for modeling, followed by overlay welding and machining *For more details, please refer to the PDF document or feel free to contact us.

Our company conducts various designs and drawing creation using 2D and 3D CAD. We provide a consistent response from conceptual proposal → design → manufacturing → assembly and adjustment → measurement and trial. We can achieve longer lifespan, cost reduction, and shorter delivery times. Leveraging the advantages of being a "material supplier," we connect material proposals to ease of manufacturing. We offer a wide range of 3D design services from product design to equipment design. 【Features】 ■ Various Designs - Design of dedicated equipment machines, general jigs ■ Reverse Engineering - Analyzing the structure of existing products using 3D measuring machines, and creating 3D models and drawings ■ Product Design Assistance - Converting paper drawings into 2D CAD data, creating 3D models from drawings ■ Mold Design - Die-casting molds, press molds, forging molds, die-casting trimming molds *For more details, please refer to the PDF materials or feel free to contact us.
