Metal Custom Brass Stamping process sequence:

1-Punching: The stamping process (including punching, blanking, trimming, cutting, etc.) that separates the sheet.

2-Bending: The stamping process of bending the Red Copper Sheet into a certain angle and shape along the bending line.

3-Deep drawing: Brass Stamping Parts process that transforms a flat sheet into various open hollow parts, or further changes the shape and size of the hollow parts.

4-Fine blanking: For products with high blanking precision, products with high requirements on size and surface light can be achieved through fine blanking molds to meet the requirements of the drawings.

5-Local forming: the Brass Stamping process (including flanging, bulging, leveling and shaping processes, etc.) that uses various local deformations of different properties to change the shape of the blank or Brass stamping part.

In-die riveting---Technology of in-die riveting of silver contacts in stamping dies


In the world of progressive in die silver contact riveting, technological improvements one after another have brought about improvements in quality, efficiency, time and other aspects. In layman's terms: I can make things better, faster, and at a higher cost. If it is lower, it will bring about the improvement and optimization of the overall efficiency of the industrial chain.


In the relay industry (take the dynamic spring assembly in the T73 model as an example), when there is no in-mold riveting silver contact process:

First, the stamping plant will send the two parts of the Relay moving spring and the Relay armature to the customer through the production;

Second, the customer riveted 1, the armature to the moving reed in his own workshop; 2, riveted the silver contact to the (already riveted armature and moving reed). In this whole process, a total of the following dies are required: a armature stamping die, b relay moving reed die, c armature riveting moving reed die, d silver contact riveting die. In terms of production efficiency, the process of riveting the Silver Electrical Contact (on the already riveted armature and moving reed) alone, a more skilled worker can only produce 10,000 pieces a day, even if this process is replaced by For automated operations, it is still necessary to optimize the process of riveting the armature to the moving reed. The longer the process is stretched, the greater the probability of quality problems between each process. Therefore, in the previous production process of moving reed components, the general daily production capacity was only 10,000 pieces (including overtime, at most 20,000 pieces) ), and when these moving reed components are installed in the T73 finished product, the adjustment-free rate of finished product assembly can only be reached 50%-60%. Let's calculate the assembly cost: at 3,000 yuan per person, 30 days, 10,000 pieces a day, the assembly cost of the last process of a moving reed assembly is 0.01 yuan (this is only the labor cost of the last process, excluding other assembly costs of the process and any quality issues).

Let’s now take a look at the process of in-die riveting of silver contacts (also take the dynamic spring assembly in the T73 model as an example)


1. The stamping plant produces the armature; 2. The stamping plant directly completes the production of the movable reed assembly by using the silver contacts through the in-die riveting process;


Second, customers only need to provide Electrical Contact Rivet to the stamping factory; in this whole process, only two dies are needed: a armature stamping die, b Electrical Silver Contacts riveting die in the movable reed die (that is, the production of the movable reed and the armature, contact All the riveting is done in this die). In terms of production efficiency, the speed of this process can be stably controlled between 200 times to 400 times (per minute). If we calculate 300 times per minute, we can achieve the production of 18,000 moving reed components in one hour, 6 hours a day can reach the output of 100,000 pcs.More importantly, the riveting process of the client is directly cancelled here, which saves manpower and shortens the process to: it can only be completed in the production workshop of the stamping plant. And the relay movable reed assembly produced by the Silver Contact Rivet in-die riveting process, when assembled into the T73 finished product, the adjustment-free rate can reach 80%-85%, which greatly improves the quality and output of the customer's finished product. Through the improvement of this technology, we found that the customer's monthly output has increased from 1.5 million finished products to the current monthly output of 5.1 million finished products, which is a full increase of more than three times!


The competitive advantage brought by technological improvement is obvious. In addition to the rising labor costs in the manufacturing industry, more and more relay assembly manufacturers have begun to invest or update automated production lines, and higher requirements are placed on supporting stamping parts suppliers. Electrical Contact Point In-die riveting technology has played an active role in this key component.
