We would like to introduce a case where we solved the customer's issue of "unable to manage the dimensions and shape of parts that require surface treatment." In response to the problem of shape distortion and deviation from dimensional tolerances due to LAP and coating, we manufactured the parts including coating from processing. We provided dimensional indications prior to processing and managed dimensions at the micrometer level using our LAP. By incorporating the coating into the dimensions requested by the customer, we achieved longer service life, stabilized production numbers, increased production volume, reduced costs, and decreased the frequency of part replacements. 【Case Summary】 ■ Issue - Unable to manage the dimensions and shape of parts that require surface treatment ■ Proposed Solution - Manufactured parts including coating from processing ■ Results - Increased production volume, reduced costs, decreased frequency of part replacements *For more details, please download the PDF or feel free to contact us.

We would like to introduce a case where we solved the customer's issue of "poor mold retention." The customer was experiencing problems with early-stage scratches and wear despite coating, leading to poor mold retention and low shot counts. We proposed WPC treatment. As a result, the coating became more resistant to peeling, and scratches decreased, leading to its adoption. The shot count more than doubled, and mold retention improved. 【Case Summary】 ■ Problem - Poor mold retention ■ Proposed Solution - Proposal for WPC treatment and polishing before and after WPC ■ Results of Implementation - Reduction in scratches and wear, shot count more than doubled, and improved mold retention *For more details, please download the PDF or feel free to contact us.

We would like to introduce a case where we solved a customer's issue regarding "mold lifespan." The customer consulted us about the short lifespan of punches, and we suggested enhancing the polishing before coating. Changing the material or coating carries risks, but since we only modified the polishing, they felt comfortable trying it out. After changing the Rz from around 3 to 0.8, the number of shots increased, product accuracy improved, and costs were reduced. 【Case Summary】 ■ Issue - Mold lifespan ■ Proposed Solution - Enhanced polishing before coating ■ Results - Increased number of shots, improved product accuracy, and reduced costs *For more details, please download the PDF or feel free to contact us.

We would like to introduce a case where we resolved the issue of "frequent deficiencies in drawings and specification changes leading to rework" that our customer faced.

We would like to introduce a case where we solved the customer's issue of "difficulty in meeting the surface roughness and shape tolerances specified in the drawings." There are often cases where trying to meet the surface roughness leads to distortion of the shape, and trying to maintain the shape results in failing to meet the surface roughness. In response to this problem, we proposed a method of performing polishing based on the contour measurement values obtained from a three-dimensional measuring machine. With a robust inspection system that allows for accurate measurements and reliable polishing techniques, we were able to implement this solution. As a result, our internal technical capabilities have improved, and we have been able to take on more challenging projects. [Case Overview (Partial)] ■ Issue - Difficulty in meeting the surface roughness and shape tolerances specified in the drawings. ■ Proposed Solution - Suggesting the necessary allowances and roughness for polishing during the work production stage. - If the sales department places a production request, it becomes easier to specify the required allowances and roughness. *For more details, please download the PDF or feel free to contact us.
