The "Super Barrel" is a barrel plating device that can perform high-quality plating treatments on precision parts (electrical and semiconductor components) with excellent uniformity and adhesion. Thanks to its unique lid opening and closing mechanism, it minimizes the risk of small and thin parts getting caught in the lid, preventing adhesion and snagging on the inner surface. It contributes to improving defect rates while maintaining high plating efficiency. We offer a lineup including ultra-compact experimental models, manual motor-equipped types, and fully automated models. In addition to standard sizes, we can also accommodate customization of specifications and dimensions. 【Features】 ■ High internal product agitation efficiency, resulting in excellent uniformity of plating thickness ■ Specially designed electrodes that do not deform even for easily bendable products ■ Capable of meeting needs such as extending barrel lifespan and reducing plating time *For more details, please refer to the materials available for download in PDF format. We are also offering a "Case Study Collection" that introduces specification examples! Feel free to contact us for inquiries.

We would like to introduce a case study of the "Super Dryer" that was implemented. A customer involved in plating precision parts was struggling with drying time and deformation issues during the drying process, which is the final step of plating. As a solution, they adopted our product. The drying was carried out without moving the parts at all, using a super strong airflow at a low temperature of around 60-70°C for about 5-10 minutes, effectively resolving the issues. [Case Study] <Problems> ■ Significant drying time was required to completely dry ultra-fine products. ■ Deformation occurred during the drying of parts with thin legs, as well as complex and thin shapes. <Implementation Effects> ■ Significant reduction in drying time. ■ A secondary effect of reducing drying stains was also confirmed. *For more details, please refer to the PDF document or feel free to contact us.

Here is a case study introducing the "open-type inclined barrel" equipped with a liquid circulation pump. In a customer’s operation where ultra-fine precision parts are plated using a conventional sealed barrel with a lid opening and closing, the liquid renewal inside and outside the barrel was poor due to the sealed design. As a result, the metal concentration was depleted during the plating process, leading to defects caused by voltage issues. In response, we proposed our product. Additionally, the design allows for easy one-touch detachment of the barrel, enabling the preparation of multiple barrels with different sizes and specifications for various plating products, thus accommodating small-batch, diverse plating processes. 【Case Study】 <Implementation Effects> ■ Capable of handling small-batch, diverse plating processes ■ Improved uniformity of the plating film ■ Enhanced liquid renewal due to the circulation pump ■ Reduction of sticking and floating of ultra-fine products inside the barrel achieved through radial liquid ejection *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce a case study that implemented our original "four-sided drop lid (slide opening and closing mechanism)." In terms of design, we manufactured with a lid clearance of at least 0.3 mm for large barrels, 0.2 mm for medium barrels, and 0.1 mm for small barrels, addressing issues with the clamping of extremely small and thin parts. As a result, we successfully eliminated unnecessary sorting processes after the plating process, achieving significant cost reductions. [Case Study] <Problems> ■ We want to eliminate product lid clamping defects and reduce costs. ■ We aim to extend the lifespan by suppressing barrel deformation. <Implementation Effects> ■ Achieved significant cost reductions. ■ Enabled longer lifespan than before. *For more details, please refer to the PDF document or feel free to contact us.

Being a water-dilutable type, it has a long liquid lifespan, significantly enhances quality, reduces running costs, and contributes to environmental conservation. 【Features】 ■ A water-based neutral degreasing cleaner for various metals, glass, plastics, etc. ■ Degreasing power equivalent to or greater than that of chlorinated solvents ■ Significantly enhances quality, reduces running costs, and contributes to environmental conservation ■ Excellent penetration into degreasing cleaning products ■ Outstanding degreasing power for products with extremely fine deep holes and flat products that are prone to adhesion *For more details, please refer to the PDF document or feel free to contact us.

• Cleaning agents

"EIKO L-50" is a phosphoric acid-based cleaning agent for cleaning steel, copper, and copper alloys. It removes various types of dirt such as rust, buffing residue, pressing oil, and animal and vegetable oils in a short time. Additionally, it prevents re-oxidation due to its temporary rust prevention effect. Mild oils and rust can be cleaned simultaneously, but for heavily soiled items, it is better to perform a preliminary degreasing (EIKO LR-3) before treatment to prevent the oxidation of the liquid. 【Features】 ■ Phosphoric acid-based cleaning agent for cleaning steel, copper, and copper alloys ■ Removes various types of dirt such as rust, buffing residue, pressing oil, and animal and vegetable oils in a short time ■ Prevents re-oxidation due to its temporary rust prevention effect ■ Mild oils and rust can be cleaned simultaneously *For more details, please refer to the PDF document or feel free to contact us.
