Q & A

Is it possible to obtain injection molded products with highly accurate measurements?

The accuracy of our injection-molded products is typically determined by the choice of molding material, the optimal mold cooling circuit, structure and gate position, and molding conditions. Details will be determined and proposed in advance to obtain the optimal molded product.

Can a more precise resin product be obtained by switching from injection molding to post-processing?

Post-processing after injection molding is, for example, similar to outer diameter polishing and numerical control (NC) lathe processing. The outer diameter runout accuracy of long objects can be achieved on the order of 10 μm, by post-processing. Post-processing of banknote transport rollers is performed at 10 μm, or less at Yokoi.

Is it possible to radiate heat from plastics?

Yokoi has succeeded in developing a material with a high thermal conductivity (up to 30 W/K). Combined with the high radiation characteristics of plastic, the heat dissipation effect is enhanced. Optimal material proposals are possible depending on the application.
