Six methods of prevent damage of stamping parts

The service life of hardware mold and die structure design, selection of die steel and heat treatment, surface treatment, mechanical processing and grinding, wire cutting process, stamping equipment, stamping parts, materials and process, mould lubrication, poor maintenance level of many factors. Failure of various kinds of factors, which cause mould structure is reasonable, improperly accounted for about 25% of select material, improper heat treatment accounted for about 45%, technology title accounted for about 10%; Equipment subject, smooth factors accounted for about 20%. Gold stamping after installation should pay attention to maintenance, prevent rust erosion. In daily use to light off light, prevent hard off the hard drive, damage. Here is how to prevent damage of metal stamping parts: 1, with hardware fittings type, specification and function should comply with the current national scale and the relevant designated, and match the selection of window of model steel door. 2, push-pull window of width more than 1 meter, or installed double glass Windows and doors, should set up the double pulley, or choose to move the pulleys. 3, friction hinge shall not adopt aluminum alloy material, stainless steel materials should be adopted. 4, with fastening screw mounting hardware, it is necessary with metal liner, liner thickness should be greater than fasteners teeth at least twice the distance. Shall not be tightened on the plastic material, also shall not use non-metal lining. 5, hardware accessories should be the final installation, door locks, handles, etc should be after the doors into the window frame assembly again, guarantee the accuracy of the position, switch is quick. 6, metal stamping parts installed to pay more attention to maintenance, prevent the erosion of rust. In daily use to light off light, prevent hard off the hard drive, damage. There is no noise, have now nylon wheel. It not only push and pull up and there is no noise, and more smooth, light, short service life than the above all kinds of pulley. To make ( The door) Window is normal. To give (running smoothly The door) Choose a high quality of pulley Windows. Inferior pulley on the surface, do manual work is relatively coarse. There is no smooth. Sliding up and not flexible. Small and light. The previous: metal stamping mold analysis
