Molding technology

Molding engineers take the lead in determining molding conditions based on proven theoretical knowledge. In order to establish conditions that facilitate stable, reproducible mass production, the results of analyses conducted by molding engineers are fed back into the mold design process. We accommodate customer needs through the use of composite molding techniques that make full use of robotic equipment and proprietary facilities.

Two-material molding and insert composite molding

Meter impeller

Extremely accurate mold-fixing technology

In order to utilize properties of two types of materials, we propose new products that make full use of molds for two-material molding. Moreover, we use technology for fixing molds for insert parts to implement two-material molding and insert composite molding.
