The process of In-die Riveting Silver Contacts

The process steps of the riveting of the silver contact riveting terminal in the mold: Contact Point progressive die punching brake reed → moving reed pickling → riveting Electrical Silver Contacts → bending of the Moving Spring Contact Assembly. Due to the large production volume of this product, in order to improve Production efficiency, stable product quality, and reduce production costs. The new process route formulated is: progressive die with material to produce moving reed strip → strip cleaning → strip riveting Electrical Silver Contacts and forming.


The technical requirements for the riveting of in-die silver contact riveting terminals: to achieve good in-mold riveting, the machining accuracy of mold parts is extremely high, oil cutting, PG, JG and other high-precision processing equipment are required; at the same time, the vibration plate and the mold are required. and the requirements for the gap and segment difference of the riveted Silver Contact Point and shrapnel are very high.

Metal Custom Copper 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: Copper 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 Copper 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 stamping part.

What is the effect of silver plating on copper surface

1-Reduce resistance and avoid rust;

2-Prevent oxidation of the copper layer and reduce electrical conductivity;

3-Bare copper is easy to oxidize. After silver plating, oxidation can be reduced and oxidation resistance can be improved;

4-It can also increase the weldability and is easy to weld.


Advantages of silver plating on Metal Stamping Parts Electric Copper surface:

1-Silver is the best conductive conductor, and the conductivity of the substrate can be improved after silver plating;

2-Silver inherently has characteristics that make it resistant to microbes and bacterial growth; making items coated safer and more hygienic to use;

3-Silver is resistant to corrosion which helps to extend the life of the plated item Copper Stamping Parts;

4-Silver has the highest degree of optical reflectivity of any metal which makes it ideal for items such as medical lasers;

5-Silver is one of the least expensive precious metals and choosing it over other precious metals, such as gold or palladium, can save you quite a bit of money.
