The corrosion resistance of material KD20, which excels in balancing mold life and precision machinability, has been further improved in WD20.
We will respond to your desire to extend the lifespan of mold parts! Proposal for improving wear resistance of carbide parts.
Our company contributes to solving the problems faced by our customers, such as improving the lifespan of mold parts. We received an inquiry from a customer stating, "We are punching work materials with a carbide punch, but the wear at the tip is severe. We want to extend the lifespan of the punch to increase productivity." In response, we analyzed the worn punch we received. It was determined that iron was adhering to the punch tip, accelerating wear. Therefore, we proposed a carbide material that is less prone to iron adhesion. After implementing the countermeasure, despite the new material having a higher number of strokes, the amount of adhered work material decreased, resulting in less wear. [Case Study] [Before Countermeasure Material] ■ Number of Strokes: 500,000 to 1,500,000 ■ Wear at Punch Tip: Approximately 0.8mm ↓ [After Countermeasure Material] ■ Number of Strokes: 1,800,000 ■ Wear at Punch Tip: Approximately 0.2mm *For more details, please refer to the PDF document or feel free to contact us.
Mold parts that are resistant to wear and chipping due to adhesion of electrical steel sheets, chipping caused by the impact of press processing, and corrosion from water-cutting wire processing!
Electromagnetic steel sheets are essential for motor cores, but we often hear about issues such as corrosion during processing and chipping or wear during pressing. 【Problems during Electromagnetic Steel Sheet Processing】 - Chipping due to impact during press processing - Wear and chipping caused by adhesion of the main component, iron - Corrosion from prolonged water-cutting wire processing - Damage from electrical discharge machining Everloy's "Super Hard Alloy EW Type and EX Type" are mold parts materials that can solve problems during electromagnetic steel sheet processing. - EW Type <For Punching> Compared to materials of the same hardness, it has a relatively high fracture toughness value, allowing for the prevention or improvement of cracks, chipping, and flaking without reducing hardness. It also has excellent corrosion resistance. - EX Type <For Riveting> A suitable material type for suppressing adhesion wear that occurs during the riveting process of electromagnetic steel sheets.

Non-magnetic superhard alloy
Conventional carbide materials have magnetic properties, albeit weak, making them difficult to use in press processing of magnetic materials and related equipment. However, we have completely resolved this issue by eliminating magnetism. Additionally, this carbide has a different composition from regular carbide, and the carbide formulated with this composition exhibits excellent corrosion resistance against salt and chemicals, as well as outstanding oxidation resistance at both low and high temperatures. At Silverloy, we offer a wide range of non-magnetic carbide materials that are not available from other companies. For more details, please refer to the material specifications.

< Wear-resistant, chip-resistant, adhesion-resistant > For motor core molds, ultra-hard alloy VG46
The drive motor, which is essential as a power source for next-generation vehicles, includes a motor core made by laminating electromagnetic steel sheets. These electromagnetic steel sheets are shaped through high-speed stamping, and the mold materials require high wear resistance, chipping resistance, and adhesion resistance. Fuji Roy "VG46" is a material specifically designed for motor core molds, formulated with an optimal balance of WC grain size, complex carbides, and binder. 【Features】 ◆ Resistant to chipping ◆ Minimal reduction in bending strength after electrical discharge machining * We are developing a lineup to meet further customer demands based on usage results. * For more details, please download the PDF or contact us!
As a material for precision cutting tools, it boasts overwhelming sharpness through grinding finishing processes and contributes to extending the lifespan of edge wear due to its high hardness.
◆ With the miniaturization and lightweighting of products, metal materials and high-performance films are becoming thinner, and high-strength materials are increasing. Consequently, tools and cutting tools used to process these materials inevitably require high wear resistance and excellent edge retention. ＼ Features of FS06 ／ ◆ High Hardness With a hardness of 95.0 HRA and a bending strength of 4000 MPa, both of which are at a very high level, it contributes to the long lifespan of cutting tools. ◆ Excellent Edge Retention Due to the nano-sized WC alloy, excellent sharp edges can be achieved on the tool cutting edge through grinding and finishing processes of #1000 or higher.

We have developed a suitable material for the punching die of motor cores. It simultaneously solves two problems: chipping and wear.
The drive motor, which is essential for the power of automobiles, uses a motor core made by laminating electrical steel sheets. The electrical steel sheets are being hardened by increasing the amount of Si added to enhance the efficiency of the motor. The mold materials used to punch these hardened electrical steel sheets require a balance of wear resistance and fracture toughness. 【Features】 ◆ A balance of high wear resistance and fracture toughness ◆ Strong against wear caused by the detachment of WC particles The VG48, developed as a dedicated material for motor core molds, is a new cemented carbide that meets all of the above features.
