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,
During stamping production, we must to do concrete analysis for defective stamping situation, adopt effective countermeasures, sovle the problem redically. Only in this way, we can cost down the production cost, and do smooth production. Now i will show you how we handle with the ten common malfunctions during our stamping production: Stamping Burr The
During stamping process, the terminals will be easily damage and deformation without protective measures, how can we protect it? The first step to protect the terminals is packing by hard paper tray, the K=K paper will be not easy to fracture and deformation. Make sure that the poly foam thickness and paper width are higher
Heju stamping worked out silver contact riveting parts in die technology in 2013. The riveting parts effect as contact and breakover for relay products. It is widely used in medical, communication, transportation, electricity, electronic and other fields. During stamping production, we must do concrete analysis for the undersirable effects, and then take effectural measures to
