Precision Drawing Work

Our expertise in technology is “Precision Drawing Work”.　We have long-time business results in small-sized motor case manufacturing; thus in regard to die design technology we have accumulated the knowledge, skills, and now-how for drawing work for both progressive- and transfer-types. Currently, we handle a number of drawing products of irregular configurations such as of cylindrical type, small-oval type, and square drawing. Now we manufacture our products in China, however, Japanese designers are in charge of the die/mold technology, and we assemble them accordingly. Our staff is doing the best they can to accumulate our business results even further as a pioneer in the drawing work.

Title	SUS case	Electro-magnetic clutch part	Special motor case
Material	SUS304　 t=0.3mm	SECC t=0.8mm	SECC t=1mm
Intended Purpose (Industry)	Sensor industry	Telecommunication OS equipment-related	General purpose machine
Distinctive Features	Draw SUS 304 in three levels by progressive press, and then process it. The thinness of the top is 0.2mm or less.	We were able to achieve the flatness of 0.02 or less in order to improve the clutch performance. Press by progressive press.	Press the central burring portion by progressive press; and the outer drawing by transfer press. This motor case has a remarkably rare configuration.
