Electronic Stamping Parts

Classification of electronic stamping parts

Electronic stamping parts are mainly classified by process and can be divided into separation and forming. The purpose of the separation process also called punching, is to separate the electronic stamped parts from the sheet along a certain contour line and to ensure the quality of the separated section. The forming process is to make the plastic sheet deform without breaking the bank and to make the workpiece of the required shape and size. In practice, multiple processes are often applied to a workpiece. Punching, bending, shearing, drawing, expanding, spinning, and straightening are some of the main stamping processes.

Advantages of using a multi-station progressive die for electronic stamping parts

 Electronic stamping parts are usually of high precision and large volume, so we usually use a multi-station progressive die to ensure the amount and precision of electronic stamping parts, excluding the single punching, die we often talk about.

 The multi-station progressive die is a multi-process die, which can include multiple processes, such as punching, forming, drawing, etc., in one die, and has higher labor productivity than a compound die and can produce quite complex stamping parts. The problem of “minimum material thickness” in compound die does not exist, so the die strength is relatively high, and the life span is long; high-speed presses can be used for production, so it is easy to automate the production and automatic release of parts, and the presses can be reduced to reduce the flow of semi-finished products, so the workshop area and warehouse area can be fully utilized. 

Advantages of continuous die for electronic stamping parts

A progressive die for electronic stamping parts is a multi-process punching die. It can achieve multiple processes such as drop, punching, forming, and drawing in one die, so it can achieve more efficient production than a compound die. At the same time, the product size is more stable and can also produce relatively complex stamping parts.

 It is a great advantage that progressive die can realize automatic production, realize automatic feeding, and automatic part discharge, and no human hand will enter the die area when producing electronic stamping parts normally; the process of progressive die can be dispersed and does not need to be concentrated in one station, so there is no problem of minimum wall thickness. Thus the strength of the die is higher, and the life of the die is longer; the production efficiency of the progressive die is higher and more cost-saving, and the electronic stamping parts produced by it are more stable. Stamping parts are more stable.

What is the role of surface treatment of electronic stamping parts

Surface treatment of electronic stamping parts refers to the process of plating a thin layer of other metals or alloys on the surface of certain metals using the electrolytic principle to prevent oxidation (such as rust), improve wear resistance, electrical conductivity, reflectivity, corrosion resistance (copper sulfate, etc.) and enhance aesthetics. The plating layer is more uniform than the hot dipping layer and is generally thinner, ranging from a few microns to tens of microns. By plating, it is possible to obtain decorative and functional surface layers on mechanical products and to repair worn and mishandled electronic stamping parts.

The surface treatment of electronic stamping parts plays the following roles

Electronic stamping parts can play a good decorative effect after electroplating; many of them are given decorative properties of different materials while taking into account the performance of surface protection systems, such as bottom plating Cu, middle plating Ni and surface plating Cr on steel workpieces, Cu layer and Ni layer play the role of protection education. In contrast, the surface plating Cr layer can keep its decorative metallic luster long.

The functional role, plating different materials and the surface of high or low-temperature resistance, electrical conductivity or insulation, magnetic conductivity or magnetic shielding, light enhancement or reflection, lubrication, biocompatibility or bio-exclusion, and other new functions to play a new role.

Vital role: The workpiece is damaged by corrosion, wear, or other factors that cause damage to the surface of electronic stamping parts. The single or compound surface treatment technology can be used to restore the dimensional surface accuracy of the workpiece and, at the same time or redesigned to give the surface performance and social functions that are comparable to or can even exceed those of the new product, to achieve the remanufacturing of the improved workpiece, assembly or product.

In addition to the functions mentioned above, the surface treatment of electronic stamping parts plays other functions, such as electrodeposition technology in surface engineering technology, magnetron sputtering technology can be used to prepare nanoparticles, nano-film, thermal spray technology to prepare nanostructured materials, etc.

Problems encountered by electronic stamping parts and their solutions

1.Electronic stamping parts manufacturers encounter bending edges that are not straight and dimensional instability.

Increase the press line or pre-bending process

The material pressing force is not enough; increase the pressing force.

Asymmetric wear of convex and concave die corners or uneven bending force, adjust the gap between convex and concave die to make it uniform and polish the convex and concave die corners.

The height size cannot be smaller than the minimum limit size.

2.The electronic precision stamping parts manufacturer encounters thin extrusion material on the bending surface

The concave die fillet is too small; increase the radius of the concave die fillet.

The gap between the convex and concave die is too small; correct the gap between the convex and concave die.


3.The bottom of concave parts is not flat in the electronic precision stamping parts manufacturer.

The material itself is not flat and needs to be leveled.

The contact area between the top plate and the material is small, or the full material force is insufficient, so the top material device should be adjusted to increase the maximum material force.

If there is no ejector device in the concave die, the ejector device should be added or corrected.

Add shaping process.
