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
In 2008, Heju Stamping was founded. Engineers team by several 20-year-experince engineers. In this 12 years, Our press machine quantity was added from several sets to 30 sets. We only worked on connector industry in the past. Now, we have took a place on auto electronic, communication, medical, etc. Our business market extends from domestic
China is the biggest import & export country, export amount increased year by year. When facing such a large market, people may wondering how to choose high-quality metal stamping supplier, to match up their quality and delivery time and other critical points. Now i will show some ways to choose the “Right Guy”. You should
Stamping dies in addition to required the mold substrate material has high strength and obdurability coordination during working, mold’s surface performance is also critical importance for working properties and tooling life time. These surface performance including: wear-resistance, corrosion-resistance, friction factors and fatigue properties etc. Through surface treatment technology, the stamping dies surface performance can be
In the great revolution of the diversity and short replacement cycle of automobile toolings, the precision stamping manufactures have been adapted to their own development in the new field. the diversity of toolings can provide more and more types of vehicles by the automobiles enterprises, meanwhile it demands higher stamping process technology, which makes a
Material Camber Reasons summarized as blow: 1.Stamping burr (especially for the carrier); 2.Material burr, tooling without trimming; 3.Improper punch depth (too deep or too shallow); 4.Part crushed, there are scrpes in the die; 5.Swaging too deep partially or local damage at swaging area; 6.Tooling design; The relative countermeasures as blow: Grinding blanking die. Change material,
