We have developed the technology to draw irregular-shaped products and are now able to reduce the turning cost by eliminating the steps between extrusion and processing. We can meet the increasing demand for non-turning parts and high precision with this technology.
Demands in these days for lightweight, high-quality, and low-volume high-variety orders, our products are used in many different fields.
Irregular-shaped drawing costs between half and one fifth of die-casting. We can meet small orders with quick delivery.
Also, the drawing process reduces the resistance in the axial direction and that improves the wear resistance of the pairing parts compared to inside diameter turning.
*We call products other than round tube and round bar 'irregular-shaped products.'
・Long tubes (over 1,000mm), even with grooves, can be produced.
・Cost is reduced by not turning or polishing.
・Improved dimensional precision compared to extruded material.
・Additional costs (such as die cost) for different lengths are not required.
・Die cost is cheaper. Between half and one fifth of casting die.
・A uniform surface is achieved.
Irregular-shaped drawing technique reduced the cost by 30%.
In traditional machining, lateral cutting tool marks caused increased resistance to piston movement. In extrusion however, the direction of manufacture is the same as the direction of piston movement, thus reducing friction and increasing piston durability.
