The difference between precision metal stamping parts and die casting parts stamped by high-speed precision punching machines-News-Dongguan Samhoor Precision Machinery Co., Ltd.

From the perspective of how the workpiece is processed, the machines and equipment used for processing, the molds used for manufacturing, and the cost of the workpiece, what is the difference between precision metal stamping parts and die casting parts stamped by high-speed precision punching machines?

1. Different processing methods

Precision metal stamping parts use high-precision molds and high-speed punch presses, and then place metal coils in the mold. They are generally punched and cut, and then produced after forming. Die castings use die casting to change the physical properties of metal, that is, to turn solid metal into a flowable molten state, and then inject the molten metal into the mold to make die castings. The processing methods of stamping parts and die castings are very different.

2. Different equipment and machines used

Precision metal stamping parts usually use high-speed and high-precision stamping equipment. For example, for stamping game coins and coins, you can use 220-ton guide column high-speed precision punching machine for processing hardware accessories game coins commemorative coins badges copper-nickel-iron steel coins jewelry accessories. High-speed precision punching presses, common ones include C-type high-speed precision punching presses and gantry high-speed precision punching presses. The punching speed of this type of equipment is generally greater than 200 times per minute, 300 times per minute is also a common punching speed, and 1000 times per minute is a very high-speed precision high-speed punching press. In addition, the processing equipment used for precision stamping parts also includes servo punching, servo motor CNC punching, hydraulic CNC punching, mechanical CNC punching, etc. In addition to stamping machines, they will also be equipped with three-in-one feeders, precision material leveling machines, material racks and other equipment according to demand;

the equipment used for die castings is die casting machines, which will also be equipped with connecting rod soup machines, servo sprayers, waste recycling conveyor lines, etc. Die casting machines are divided into vertical die casting machines and horizontal die casting machines. The equipment used for the two workpieces is very different. This is the most obvious difference in the difference between precision metal stamping parts and die casting parts stamped by high-speed precision punching machines.

3. Mold manufacturing

The mold structure of precision stamping parts is complex, and the manufacturing precision requirements are high. The production batch of the mold is small, and it has the characteristics of single-piece production. The manufacturing cost of the mold is high, and the general processing procedures are relatively concentrated. After forging, cutting, heat treatment and other processes, the materials used to manufacture the mold are required to be high. For example, for stamping precision terminals, we know that the structure of the terminals is very complex, and usually use Precision connector female terminal copper bar Inner contact cage Grid lantern spring connector terminal Brass solar terminal Medical connector terminal High speed precision punch press; die castings are generally produced by injecting molten metal into the mold, so the manufactured mold must first be resistant to high temperature, in addition, the mold must be fatigue-resistant, easy to fall off, etc., good cutting and forging properties, and the mold is divided into two types of precision, one is for the production of simple shapes, and the other is for the production of complex shapes Precision mold.

4. Workpiece cost

Alloy die castings can produce large parts in large quantities, occupying a large production site. Precision stamping parts generally use simple machines and equipped machines, occupying a small space, and small parts can be produced on a small scale. The production cost of die castings is greater than that of precision stamping parts.

The difference between precision metal stamping parts and die casting parts stamped by high-speed precision punching machines is multifaceted, and there are certain differences in product performance, product output, and scope of application.
