Direct Molding Process

Yamaha's original direct molding process begin directly with the mold, solving the frequent pull problem that plagues the traditional mold-prototype-plug-mold system.

Yamaha's original know-how in modeling, engineering, CNC processing technique, Sprayputty use, and our excellent technology make the direct mold method possible.

Direct molding allows us to make twice as many pulls as a conventional mold.
Its durability is a plus for prototypes and small quantity lots.

A conventional mold can be used 1 to 2 times at most before precision is lost. In the design phase these restrictions can be a terrible strain. The potential for dissatisfactory results in prototypes and small quantity lots is especially high. It's a terrible burden, isn't it?

Yamaha direct molding solves all the problems of pull count, precision, and manufacturing time inherent in conventional molding processes.

From drawing board to motorboat in just 7 weeks, thanks to Direct Molding!

To show off our direct molding technique, we built a one-off reproduction of a CAT-21 motorboat. This model was first built and sold in the 1960s.
