I. Overview of metal stamping parts mold
High-precision medium-speed mold/progressive mold has longer service life, lower labor production cost, more stable quality and higher precision than engineering mold and simple mold. It can integrate trimming, punching, forming, flanging, tapping, riveting and blanking. We use imported low-speed and high-speed WEDM, EDM, CNC machining center, high-precision grinding machine and other processing equipment to meet the processing requirements of precision molds.
Processing efficiency of low-speed WEDM:
(1) High processing efficiency
Due to the development of NS class high peak current pulse power supply technology and detection, control and anti-interference technology, the processing efficiency of low-speed WEDM is also improving.
(2) Processing efficiency of workpieces with large thickness
When cutting 300 mm thick workpiece, the processing efficiency can reach 170 mm2/min, which is a very significant technical improvement.
(3) Processing efficiency of workpiece with thickness change.
It can automatically detect the thickness of the workpiece and automatically adjust the processing parameters to prevent wire breakage, and achieve high processing efficiency in this state.
II. How to judge the quality of the mold?
AceReare Electric has been specialized in manufacturing molded case circuit breakers for more than ten years. Our company can engage in injection mold, pressing mold, metal stamping mold and other businesses. We are a modernized factory integrating design, development and intelligent manufacturing.
With the high standard, high quality and high demand of professional customers for product technology, we continue to invest in self-made high-precision medium-speed molds, with a total investment of up to 10 million yuan.
1. Materials: CR12MOV manganese-vanadium steel for template material, #45 medium carbon material for mold base material, DC53 and SKD-11 for punch blade and other materials
2. Improvement of the one-time pass rate of the mold
The accuracy of the mold should be high, mainly reflected in the improvement of the mold precision by the mold processing technology, and secondly, the accuracy of the punch also affects the accuracy of the product;
The mold worker should be professional, the mold worker's control of the mold accuracy and algorithm will also affect the one-time pass rate of the mold. The key dimensions of many precision molds are not allowed to have a slope, but the tolerance zone and a small slope will be fully used in mold manufacturing, such as gear installation column. When building a digital model, we must pay attention to the adjustment of tolerance. Generally, the 3D model provided by customers is useless, because many of its dimensions are the limit dimensions. If we design the mold according to this, the produced mold will basically be scrapped.
III. Mold classification
1. Multi-station mold: in a stamping production chain, use different stamping molds with different processes, use a manipulator or other automatic facilities, and use molds or parts to move to complete the rated mold for workpiece stamping processing
2. Progressive mold: also called continuous mold, the material belt always moves in one direction during the stamping process; A progressive mold is one in which the strip inside the mold moves in two or more directions after being cut off. The automatic feeding continuous mold is used to complete the feeding of the material belt inside the mold. In real life, in order to get the same workpiece, mass production is also required. Then, we need to use the mold. In order to achieve rapid and stable continuous production, continuous mold is generated.

V. Our mold advantages and highlights
1. We can meet customers' needs for mass production
Production speed of continuous stamping mold (up to 200SPM times-800SPM times/minute.
2. Product design process arrangement is relatively easy
During mold design, it is decomposed into precise and simple setting structures according to product requirements, and arranged in different stations to avoid the vulnerable parts of the mold station structure and increase its life, which can reach more than 500W strokes.
3. Economy
The production and processing of continuous stamping mold can save processing materials, control the mold step, and improve the material utilization rate. At the same time, it can reduce the management of operation, handling and other labor as well as the occupied area of the site, so it is economical.
4. Degree of work hardening in drawing process is moderated
When the drawing process is carried out in the continuous mold, the drawing rate can be increased and the number of drawing times can be increased, so as to ease the degree of work hardening of materials and avoid the need for annealing of semi-finished products during processing.
5. With operational security
The continuous stamping mold is an automatic stamping mold, which does not need manual operation during processing and has no possibility of hurting human body. When the feeder breaks down or other unexpected events occur, the punch can stop immediately to avoid damage to the punch.
6. For the connecting plate series, we integrate the process to develop mold tapping, which is efficient in production and saves manpower.
7. The product is of high precision, from trimming and unfolding to blanking after bending and forming, it is all completed by one set of mold manufacturing.
VI. Difference between precision mold and ordinary mold
It is mainly reflected in the accuracy. The key dimensions of many precision molds are not allowed to have a slope, but the tolerance zone and a small slope will be fully used in mold manufacturing, such as gear installation column. When building a digital model, we must pay attention to the adjustment of tolerance. Generally, the 3D model provided by customers is useless, because many of its dimensions are the limit dimensions. If we design the mold according to this, the produced mold will basically be scrapped.
