Our company contributes to solving the problems faced by our customers, such as improving the lifespan of mold parts. "Chipping occurs on mold parts, leading to damage, and we want to improve this." Do you have such concerns? We first check the damaged areas of the mold, its shape, material type, and usage conditions. If the current material type of the mold is unknown, we conduct a material property investigation to identify the material being used. Based on the confirmed data, we will propose a suitable material type for damage prevention. [Main Application Areas] ■ Automotive parts: Electrical components, powder molding mold parts ■ Battery-related: Mold parts for transfer presses, powder molding mold parts ■ Motor-related: Mold parts for motor cores ■ Rolling-related: Rolling rolls, side rolls *For more details, please refer to the PDF document or feel free to contact us.

Our company contributes to solving the problems faced by our customers, such as improving the lifespan of mold parts. Damage to mold parts can sometimes be caused by corrosion. The factors contributing to corrosion include moisture adhesion, the effects of electrical discharge machining, and processing fluids, among others. There is a significant difference in the amount of corrosion depending on the material type. We will inquire about the usage conditions and propose appropriate material types to suppress corrosion. [Main Application Areas] ■ Automotive parts: Electrical components, powder molding mold parts ■ Battery-related: Mold parts for transfer presses, powder molding mold parts ■ Motor-related: Mold parts for motor cores ■ Rolling-related: Rolling rolls, side rolls *For more details, please refer to the PDF materials or feel free to contact us.

Everloy, a specialized manufacturer of cemented carbide, conducts integrated production from sintering to processing of cemented carbide materials. This is a cemented carbide pin-point gate bush that is hard and resistant to wear. It is used in injection molding molds for high-hardness resins, ensuring stable quality and extending the lifespan of the gate bush due to its wear resistance. Custom production is available from a single piece with desired dimensions such as gate angle, hole diameter, and slope. We also accommodate inner surface lapping processing.

Do you have any of these troubles? "The nozzles in use wear out over time, leading to increased flow rates and irregular patterns, resulting in significant performance degradation, and we frequently replace them with new ones. We want to stabilize performance and extend the replacement cycle..." Our company is a specialized manufacturer of spray nozzles and carbide materials. We leverage our strengths in these two fields to contribute to solving our customers' problems. 【Wear Prevention Case Study】 We analyze the used nozzles after confirming the usage conditions. By applying carbide materials to the orifice section of the spray nozzle, we make the nozzles less prone to wear, reducing the frequency of replacements. This has improved production efficiency and led to cost reductions. *For more details, please refer to the PDF document or feel free to contact us.

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.
