Normally for stamping process like piercing, blanking & cutting craft, try to avoid using high hardness or very brittle materials. Because there’s tearing phenomenon in the blanking process, if material is too hard (carbon steel), it is very easy to be broken and cause bad cutting edge. So better to choose softer, fluid and elastic
Stainless steel has a low elongation rate, a large elastic modulus E, and a high hardening index. The cracking of stainless steel drawing parts sometimes occurs after the drawing deformation, sometimes when the deep drawing part is withdrawn from the die matrix; sometimes it occurs when it is impacted or vibrated after drawing deformation; sometimes
There are many types of tooling, including single die, compound die and progressive die. To determine tooling form, it must be based on the requirements of the stamping parts, production batch quantity, and tooling fabrication condition. What is Metal Stamping Die? Stamping die is a special process equipment for processing materials (metal or non-metal) into
2020 was an extraordinary year, due to the global epidemic of COVID-19, it’s also a challenging and harvest year for HEJU. In the 2020, under the leadership and support of General manager Mr.Huang, the whole company is united to overcome difficulties and closely focus on the turnover target set at the beginning of 2020, seize
What is Perforated Metal? Perforated metal also called as perforated sheet, perforated plate or perforated screen; Stainless steel perforated sheets is made the stainless steel by manually or stamping or piercing. Normally it is round hole, square hole or other decorated patterns. Raw material may use stainless steel, cold roll steel, galvanized steel, brass, aluminum
Fine blanking is a non-cutting processing technology. It’s a precision blanking method developed on the general blanking technology. It can obtain the higher quality fine blanking part during one shoot, which have higher precision dimension, more smooth cutting surface, lower warping degree and interchangeability compare to the common stamping part. Also the fine blanking could
Step1: Stamping Process Analysis of Stamping Parts Stamping parts must have good stamping technology, in order to be product qualified stamping parts in simplest and most economical way. Stamping technology analysis can be completed by following according to following methods. 1. Review product diagram. Except for shape and dimension of stamping parts, It’s important to
Nowadays, metal stamping parts are widely used in daily life products. The demand of stamping die from manufacturers is also increasing. Therefore, stamping die daily maintenance is very important. If we can maintain the stamping die regularly, the stamping die life time will be increased. 3 Levels of Metal Stamping Die Maintenance: level 1,
It is believed that many metal stamping factories do not know what process to use for forming small holes which smaller than the raw material thickness. There are products will need this kind of small holes, such as mobile phone handsets, earphone speakers, Bluetooth speaker nets, filters, heat sinks, etc. Below are the advantages and
