1、 In practical processing, it is necessary to observe and analyze more, so that problems can be dealt with quickly and effectively. In fact, the production and processing of metal stretching parts are not so complicated, and can produce metal stretching parts that satisfy customers.

Secondly, as hardware stretching parts are exterior components, they require good surface quality and a scratch free surface. Because it is a glass film production and processing, the surface quality of the entire top can be basically determined. In the early trial molding stage, scratches have been occurring on the side edges, and the problem will be solved through exploration and analysis. Thirdly, for stainless steel materials, the roughness of the surface of the metal stretching part mold also has a significant impact on the surface quality of the equipment. It is recommended to polish and polish the mold surface as much as possible. 4. For hardware stretching parts, when selecting raw materials, it is important to choose materials that are soft and easily stretched. For some special products, it is necessary to consider both stretching and quenching at the same time. 5. For products with relatively high height or small diameter, at the beginning of mold design, it is necessary to estimate how many stretching processes are needed. If the process design is too few, it may also cause scratches.

Sixth, because metal stretching parts are a process that produces strong deformation, hydraulic presses should be used as much as possible to complete production and processing. Mechanical stamping machines have a too fast stamping process speed, which can easily cause the surface quality of the product to fail to meet the requirements during production.

. 7. When designing the gap between metal stretching parts molds, it is necessary to fully consider the products specifications, materials, thickness, and stretching height. Errors in mold gap design can also cause scratches.
