We would like to introduce our "Screw Cleaning" service. Yepco cleaning uses plastic-based agents to project and remove dirt without damaging the metal, unlike surface treatment. It is commonly used for cleaning molds and the plasticizing components of injection molding machines. Since it cleans in a dry environment without using heat or solvents, it can be incorporated back into the production line immediately after cleaning. 【Main Target Items】 ■ Injection molding plasticizing components (screw, three-piece set, nozzle) *For more details, please refer to the related link page or feel free to contact us.

We would like to introduce our "Plating and Coating Treatment." YEPKO treatment can be combined with surface treatments such as plating and coating. By incorporating YEPKO in the processes before and after surface treatment, we enhance the effectiveness of the surface treatment. By creating a base layer before film formation to make the surface less prone to peeling, and applying YEPKO treatment after film formation to seal fine cracks, we extend the lifespan of the surface treatment. Various combinations with different platings and coatings are possible, and it is also effective for post-processing such as heat treatment. [Main Target Products] ■ Various molds ■ Processing tools *For more details, please refer to the related link page or feel free to contact us.

We would like to introduce a case study on "Countermeasures for Release Failure of Medical Filters in Plastic Injection Molding." The surface of the mold used for plastic molding has many polishing scratches, which cause the molding material to stick, resulting in damage to the molded products during ejection, making continuous molding difficult. After treatment, fine burrs and edges were removed, and the metal surface was smoothed and made more slippery, which improved the release and enabled continuous molding. 【Overview of the Plastic Case】 ■ Issues - The surface of the mold used for plastic molding has many polishing scratches, which cause the molding material to stick, resulting in damage to the molded products during ejection and making continuous molding difficult. ■ After Treatment - Release improved, enabling continuous molding. *For more details, please refer to the related link page or feel free to contact us.

With the Yepco treatment, it is possible to achieve a complete polish-free finish or significantly reduce polishing time. It is effective for processing hard-to-polish areas such as the corners of pockets and narrow gaps with complex shapes. By using fine agents and projecting them with low air pressure, it is possible to protect the shapes of critical edges. This is effective for processing connector molding dies and punching press punches. In the case of "Mold Discharge White Layer Removal," the surface discharge white layer was removed by spraying the agent. 【Case Summary】 <Mold Discharge White Layer Removal (Electrical Discharge Machining)> ■Issues - When performing electrical discharge machining, the metal components melt, resulting in a discharge white layer on the metal surface. ■After Treatment - The surface discharge white layer can be removed by spraying the agent. - By controlling the pressure of the spray on the hardened layer, it is possible to remove it without deforming the product. *For more details, please refer to the related link page or feel free to contact us.

The Yepco treatment can remove processing burrs and edges that cause galling, and it enables the metal surface to have the sliding properties of a tribo finish. As a result, it becomes less prone to galling, reduces the amount of applied grease, prevents grease contamination, lowers the resistance of sliding components, and extends their lifespan. In the case of the "star-shaped sample free fall," the clearance was finished to 2-3 μm, and further, due to the effects of the tribo finish treatment, smooth sliding was achieved. 【Case Summary】 <Star-shaped Sample Free Fall> ■Issues - Polishing makes dimensional adjustments difficult, and even the best craftsmen can produce uneven results. ■After Treatment - Dimensions can be adjusted, allowing for a finish with a clearance of 2-3 μm. - The effects of the tribo finish treatment enable smooth sliding. *For more details, please refer to the related link page or feel free to contact us.

YEPKO's surface modification technology, which rejuvenates metal surfaces, solves these "troubles." ◯ Hand polishing takes too much time ◯ Poor release properties ◯ Mold deposits are easily attached ◯ Short lifespan of processing tools and parts ◯ Sliding parts are prone to seizure ◯ Want to remove machining burrs YEPKO's surface modification technology is developed through years of research by YEPKO in Switzerland. By simply spraying two uniquely developed types of particles in two stages, release properties are significantly improved, and it has dramatic effects on preventing seizure, reducing deposit adhesion, and extending the lifespan of processing tools. It can also be applied to molds that have already completed finishing processes. Since one device is used for each process, two devices make up one set. ◎ For more details, please refer to the PDF document or feel free to contact us.
