We have newly published a case study on pinhole repairs for the SC480. The "Pinhole Inlay" machine can repair small pinholes and can be used on iron-based metals. It is capable of repairing thin plates if they are 3-4mm thick or more. By using carbon ball C2.4 and polishing with a grinder, the pinhole areas on machine parts measuring H500×W460×L900 (SC480) can become indistinguishable. 【Work Procedure】 (1) Clean and enlarge the nests or scratches in the material using a center punch or similar tool. (2) Place the starlet and perform fusion filling with this machine. (3) Finish with a grinder or similar tool. (4) Complete the fusion filling. *Please download the PDF document to view the case study. Feel free to contact us regarding the product.

We have newly published examples of pinhole repairs for FC200, SS400, and SUS304. The machine "Pinhole Inlay," which can repair small pinholes, can be used on iron-based metals and can also repair thin plates if they are 3-4mm thick or more. Regarding FC200 (cast iron), there is a change in color tone after repair, but otherwise, the repair marks become indistinguishable. 【Work Procedure】 (1) Clean and enlarge the nests and scratches in the material using a center punch or similar tool. (2) Place the starlet and perform fusion filling with this machine. (3) Finish with a grinder or similar tool. (4) Complete the fusion filling. *Please download the PDF document to view the examples.

Traditionally, filtration of plating solutions was not often performed, but as a result of experiments using the simple filtration device "My Filter," it has been demonstrated that efficient filtration lowers SS concentration, leading to improved quality and cost reduction. Changing the filter bag is easy, requiring only the opening and closing of the container lid for insertion and removal. It automatically stops when clogged, thanks to a pressure gauge with a contact point. There is a wide variety of filter types available, allowing selection from precision filtration to coarse filtration according to the application. Additionally, the filters can be folded and disposed of after use, contributing to cost savings. 【Features】 ■ Easy to handle bag-type liquid filter system ■ The main body is made of heat-resistant PVC, suitable for chrome plating solutions ■ High productivity adapted for large flow rates with low pressure loss ■ Precision filtration uses non-woven fabric made of polypropylene with high accuracy ■ Coarse filtration uses polyester felt, which is long-lasting and economical *For more details, please refer to the PDF materials or feel free to contact us.
