Why precision tensile) in drawing oil

Precision electronic technology co. , LTD is a professional production and processing precision tensile) enterprises. Products are widely used in computer components, machinery, DVD, CD machine, digital switches, electronics, electrical appliances, automobile and motorcycle accessories, hardware power tools, communication tools, etc. 26 Japanese imported stamping equipment, can meet the needs of customers. Precision tensile) used in the mold, usually in punch, concave die and blank holder ring. The clearance between the punch and die is greater than the thickness of the sheet metal, due to the die diameter less than the diameter of the billet, the material to produce plastic flow, in the process of stamping tensile part to increase the height of the parts, others increase the thickness of the wall. Cutting fluid manufacturers' 'lubricating oil well found stamping tensile process is caused by the material stress internal metal interaction between the metal inside each unit cell have internal stress, in the role of internal stress, the strain state, make the material plastic deformation occurs, and constantly to pull into the concave die, eventually become a cylinder precision tensile). Stamping tensile process variant points from the material into small sections with heavy section of cylindrical workpiece. In the process, material surface and the mold surface must be contact and friction. In order to reduce the friction coefficient, the tensile oil may be used. (1), the decrease of friction between workpiece and its dies, thus reducing the tensile force. (2), which can increase the flow of metal, variant degree, reduce the drawing number. (3), to prevent the adhesive of the workpiece and its dies, ensure good demoulding effect. (4), to prevent surface scratch and wrinkle, improve the quality of drawing. (5), cooling mold, so as to improve the service life of mould. Above is pulling oil on precision tensile processing molding will play a role, can not be ignored! Precision contact: wish you a prosperous business, everything goes well, if you want to learn more dynamic, can scan the qr code, pay attention to the public. , is committed to precision stamping processing factory of the world's most professional electronic components
