Molds Business

Focusing mainly on urethane casting products,
we strive for high performance and superior quality.

About Our Molded Products

We manufacture and sell high performance, high quality urethane resin products optimized for durability and abrasion resistance in urethane casting. We also handle high performance urethane resin with excellent heat and abrasion resistance.
We take advantage of technology we have cultivated in various fields such as rollers, pulleys, semiconductor related parts, and belts to help you as a business partner in the development and commercialization of casting and molding products.

High Performance Urethane Resin

Polyurea
  • Resin with excellent heat and abrasion resistance.
  • Withstands higher temperature (120°C) compared to normal urethane resin.
  • Resin with excellent roll edge abrasion resistance. Three to five times the abrasion resistance compared to ordinary urethane resin and 154 times compared to synthetic rubber.
  • Relatively easy to obtain from low hardness (JIS A80) to high hardness (Shore D78)
  • Used in practice in cold rolling lines and surface treatment lines (swing rolls, ringer rolls, tension bridal rolls, etc.) at steel manufacturers
