Hardware shrapnel stamping

Metal shrapnel (also known as pots or metal dome, snap dome), the use of ultra-thin (0.05mm-0.1mm thickness) and ultra-thick (generally high hardness) made of stainless steel 301 or 304 material. Metal shrapnel is an important part of the switch. Metal shrapnel is mainly used in membrane switch, contact switch, PCB board, FPC board, medical equipment and other products.

Metal shrapnel is an important part of the switch. Metal shrapnel is mainly used in membrane switch, contact switch, PCB board, FPC board, medical equipment and other products. The working principle of the metal shrapnel: The metal shrapnel on the thin film key is located on the conductive part of the PCB (most of which is located above the gold finger on the circuit board). When pressed, the center of the shrapnel is concave and touches the line on the PCB , Thus forming a loop, the current through, the whole product will be able to work properly.
General conventional metal shrapnel, according to their different shapes are divided into: round metal shrapnel, cross-shaped metal shrapnel, triangular metal shrapnel, oval metal shrapnel. Diameter from 3mm to 20mm, the intensity from 100g to 600gf range. Of course, if you have a special request by your drawings to make it, there is no problem.

There are also according to the requirements of the resistance of the guests, our metal shrapnel also have nickel, silver, gold and other different surface treatment.

Hardware shrapnel is a metal stamping parts, electronic hardware category. English name: Metal shrapnel. The use of stainless steel or manganese material after heat treatment is made, is an important part of the switch, by means of the continuity of metal shrapnel, between the operator and the product play a high-quality switch role. At the same time, the use of pots of tablets of the stability of the resilience (press automatically after the return), and long life, to provide the operator with high-quality tactile feedback. Hardware shrapnel production is a special process for the processing of materials (metal or nonmetal) into parts (or semi-finished products) by cold stamping of stamping dies. Stamping is a method of applying pressure to a material at a room temperature by means of a mold mounted on a press to produce a pressure or a plastic deformation to obtain a desired pressure machining method.
