Suginami Dengyo’s products and production equipment
Precision-pressed parts
Our high-precision pressed parts, created using submicron precision dies and molds, are widely used in the connectors of devices such as mobile phones. 
Precision molds
The dies and punches used in Suginami Denki’s ultra-precise molds not only aim for high grinding precision but also aim for 0.2-μm surface roughness.  We can also accommodate parts processing for dies and punches. Please approach us with your orders. 
Production equipment
Every product made by Suginami Denki is manufactured using our high speed and high precision automatic presses. With our unique system for accommodating small lot production with tight deadlines and without stocking, we can respond to the diverse needs of our customers.  Our manufacturing policy is that carefully run production should ensure high precision and high-quality products, not inspections.
