We would like to introduce a case where we conducted mold transfer and injection molding in response to the challenge of not being able to find a factory capable of molding GF40%. Initially, molding was done at a facility other than ours, but due to issues such as burr generation, the yield was poor, causing difficulties for our customer. After the transfer to our company, a review of the molding conditions led to an improvement in the defect rate, which pleased our customer. 【Case Overview】 ■ Product: Fittings for housing equipment ■ Material: PPS with 40% glass fiber ■ Size: 12.85mm × 10mm ■ Processing Steps: Mold transfer and injection molding ■ Challenge: There were few molding factories capable of molding GF40%, and it was difficult to find a factory that could handle the poor yield caused by burr generation. ■ Key Point: Optimization of molding conditions made it possible to minimize burrs to a very small amount. *For more details, please download the PDF or feel free to contact us.

We would like to introduce a case where we received a consultation regarding the transfer of molds from an existing production factory. To maintain the same quality as the current product, we started production after conducting multiple trial runs in the molding and printing processes. Although the product shape is not particularly complex, issues often arise during mold transfers. However, by conducting multiple trial runs, we were able to maintain the same quality as the current product. 【Case Overview】 ■ Product: Stop Gauge ■ Material: Recycled PC ■ Size: 170×63×55 ■ Processing Steps: Injection Molding, Silk Printing ■ Other: Mold Transfer ■ Results: The mold transfer was completed smoothly without major issues, and the quality was maintained at the same level as the current product. *For more details, please download the PDF or feel free to contact us.
