Sino Concept works in the field of forging for many years and has built up a detailed knowledge in many specialized areas of manufacturing. Stamping and punching are both areas in which Sino Concept has exceeded the competition.
Stamping and punching are processes that are used to manufacture steel products and they are both widely used forging operations. They allow us to produce complex designs and shapes at a low cost.
Punching is a metal forming process using a press to create a hole via shearing into a metal piece. Punching is the most cost effective method to create holes in metal pieces for high volume production. In addition, thanks to its rapidity the process of stamping is an ideal solution for any volume of production. It is also very effective to create holes of various shapes.
1- Place a work piece of steel into the presses where you want the holes to be created.
2- Force a steel punch, made of strong steel into the work piece to create the holes.
3- Remove the surplus metal, which could accumulate in particular at the junction between the two dies.
Stamping is a process in which thin metal slices are shaped by punches and dies. Stamping utilizes the elasticity of the metal. The elasticity for stamping is optimal when the temperature is between one-third and one-half of the metal’s melting temperature. Once cooled down, the material returns to its original strength.
There are two different kinds of punches and dies: mechanical or hydraulic presses. Most stamping operations are carried out on high-speed mechanical presses even though they are more expensive than hydraulic presses.
1- Place a pre-heated steel sheet between an upper and a lower mold.
2- Press the machine to force the molds together.
3- You obtain a piece of metal with the desired shape.
This stamping process is used to create e.g. our outdoor trash receptacle.
