In our daily life, many of the products we see are precision metal stamping parts, ranging from airplanes and automobiles to small pins. What are the characteristics and common problems of metal stamping parts?

Main features of metal stamping parts

Stamping parts not only require the required shape, but also must ensure strict quality. The quality indicators of stamping parts are mainly thickness thinning rate, dimensional accuracy, surface quality and physical and mechanical properties of the formed material.

1. Metal stamping parts are made by stamping under the premise of low material consumption. The parts are light in weight and good in rigidity. After the sheet is plastically deformed, the internal structure of the metal is improved, so that the strength of the stamping parts is improved. improved.

1. The metal stamping parts have high dimensional accuracy, are uniform in size with the mold parts, and have good interchangeability. No further machining is required to meet general assembly and use requirements.

1. During the stamping process, since the surface of the material is not damaged, it has better surface quality and a smooth and beautiful appearance, which provides convenient conditions for surface painting, electroplating, phosphating and other surface treatments.

How to choose the material of metal stamping parts

How to choose the material of metal stamping parts? Most of our processed metal stamping parts include red copper, brass, phosphor bronze, stainless steel, iron, aluminum, carbon steel, nickel, spring steel and other stamping materials. There are also some alloys with good plasticity that are also a kind of metal stamping materials, but this depends on whether the customer requires this material for processing. So how should we choose the material of metal stamping parts?

1. Selection of sheet coil width: In the type of steel plate specifications, whether it is a fixed-length sheet or a coil sheet, the same material and material thickness have different sales prices for different coil widths. Therefore, in order to reduce costs, it is necessary to work hard on the formulation of the purchase roll width, and try to select a roll width range that does not increase the price on the premise of ensuring the utilization rate of materials. For example, try to choose the appropriate size for the fixed-length plate. After cutting from the steel mill, there is no need to carry out secondary shearing, which reduces the cost of shearing; Cut workload and improve work efficiency.

1. Selection of plate thickness deviation: There are deviation requirements for the thickness of the plate, usually within the allowable range of deviation, the plate with the lower deviation should be selected first.

1. Material and material thickness: When selecting materials for product design, avoid using high-grade materials to cause excess product performance. At the same time, on the premise of meeting product and process requirements, try to choose materials and material thicknesses used in existing mass-produced models, forming a material platform to facilitate subsequent procurement and inventory management.
