The accumulation of scrap during press processing is one of the inseparable issues in press processing, as it can lead to defects caused by product dents and damage to molds, punches, button dies, and jigs due to double punching. Factors contributing to scrap accumulation include adhesion due to vacuum, adhesion to the punch cutting edge, and lifting caused by compressed air in the die. Measures against these factors include processing the cutting edge of the punch, adding air holes to the punch, installing ejector pins, and making the die cutting edge all taper. However, replacing punches and dies, design changes, and equipment adjustments require time and cost. The "Depo Series" is our original patented product that can be used for both preventive maintenance coatings and repair on machine parts and molds, applying the principles of electrical discharge machining. By coating the sides and bottom of the punch with tungsten carbide, wear resistance and anti-seizing properties are imparted, preventing the lifting and adhesion of the stripping plate when removing the punch. This is particularly effective for sticky materials such as stainless steel and aluminum.

In aluminum die casting and casting molds, high-temperature molten aluminum flows at high speed, causing erosion and melting on the mold surface. Additionally, heat expansion and cooling contraction lead to the occurrence of heat cracks. The Depo series prevents mold melting, seizing, galling, and heat cracks by coating with cermet electrodes, improving fluidity and reducing the defect rate of products.

It is possible to easily repair scratches, galling, wear, corrosion, pinholes, processing errors, etc. on molds and machine parts on-site using distortion-free, second shrinkage, and stress-free buildup welding.

Vibrodine is... When heating and cooling in metal processing, welding, casting, etc., stresses occur beneath the surface, which can later lead to problems such as distortion and cracks. Generally, these stresses are removed through heat treatment, but with Vibrodine, it is possible to achieve a similar effect by applying special mechanical vibrations to the workpiece. Additionally, Vibrodine treatment is economically advantageous compared to heat treatment, with shorter lead times and equipment and processing costs being less than one-tenth, while energy consumption is less than one-hundredth, making it an eco-friendly machine that is gentle on the Earth's environment. Vibrodine is a new vibration-based device for removing internal metal stresses and stabilizing metals.

This is our original patented product that can be used for both preventive maintenance coatings and build-up repairs on machine parts, molds, etc., applying the principles of discharge machining. Coating and build-up can be performed without causing thermal effects such as distortion or shrinkage to the workpiece. The device is portable and can be used with a 100V power supply, making it ideal for repair work on-site. It eliminates downtime due to repairs and waste from spare parts inventory, resulting in increased productivity and reduced costs.

The "Depo Series" is our original patented product that applies the principles of discharge machining. It can be used for both surface treatment (coating) that enables mold repair and the repair of machine and equipment parts, as well as extending their lifespan. It allows for buildup repair and surface treatment (coating) without causing thermal effects such as warping or shrinkage to the workpiece. The device is portable and can be used with a 100V power supply, making it suitable for repair work on-site. 【Applications and Examples】 ■ Surface treatment of die-cast molds / Prevention of melting and seizure, preventive maintenance ■ Buildup repair of plastic and rubber molding molds / Burr prevention, PL part repair ■ Coating of press molds / Prevention of galling, seizure, and debris accumulation ■ Buildup repair of aluminum molds and products / Pinhole repair and more ■ Buildup repair and coating of various machine parts, tools, etc. *For more details, please contact us or download the PDF.

The "TL Series" is a high-performance, low-cost original (made in Japan) laser welding machine. With just a short training period, anyone can achieve precise, high-quality build-up and welding without distortion, undercuts, or pinholes. It is capable of build-up and welding on almost all types of steel, as well as aluminum, copper alloys, titanium, stainless steel, and gold, including dissimilar metal build-up and welding. 【Features】 - The build-up material alloying and diffusing with the work surface results in strong adhesion that does not peel off. - The amount of build-up can be controlled to a minimum, significantly reducing finishing time and costs. - Since the build-up can be done with the same material as the workpiece, there is no hardness difference. It enables repairs, maintenance, and design changes that were previously impossible. *For more details, please contact us or download the PDF.
