The place that was processing urethane rubber has gone out of business! We have created a simple mold in-house!
We would like to introduce a case study of the production of "Drive Rollers." The company that was processing urethane rubber went out of business, and we received the request. We manufactured a simple mold in-house. The tolerance of Φ16.24+0.05-0 is challenging, and the shaft measuring 390L×Φ6 falls into the category of being elongated. However, such grinding and polishing processes were previously outsourced to suppliers before 2010, so being able to do this in-house now is a significant step forward. 【Case Overview】 ■ Product Name: Drive Roller ・ Φ16.24×15×2 locations ■ Processing: Casting (with mold) + Urethane Rubber Grinding and Polishing ■ Production Period: 2 weeks *For more details, please refer to the PDF document or feel free to contact us.

Company information
Ritsusei Chemical Industry Co., Ltd. conducts a consistent process from casting to polishing of urethane products. We handle urethane rubber hardness ranging from low hardness (25-30 degrees) to high hardness (95-100 degrees). Generally, casting urethane is done at atmospheric pressure, and for simple shapes, it can be produced without using molds.
