Surface Treatment Technology of Stamping Dies

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

How To Handle With The Ten Common Malfunctions For Stamping Die?(2)

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,

How to Protect Terminals During Metal Stamping Process?

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

How to Solve the Undersirable Effects of the Silver Contact Riveting Parts

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

Advantage of Progressive Die

Progressive die is the name of the die structure,basically can be interpreted as stamping parts can’t finish production from any one stamping die in one-time stamping by punching, bent or amplify mold,etc.It must use many sets die or many process to finish stamping.Design these parts of multi project or multi die in the same die,use math
