Coupling is a device that connects two shafts or shafts and rotating parts and rotates together without disengaging during the transmission of motion and torque. It does not change the direction of rotation and the size of torque during transmission. The common function of the shaft. The elastic cou... Read More
The parameters of zinc alloy die-casting are specific pressure and filling speed, both of which are the most important process parameters in the die-casting process. Other process parameters include filling time and mold temperature. Die casting is a metal casting process, which is characteri... Read More
The essence of zinc alloy die-casting is that the liquid alloy is filled into the die-casting mold cavity in a very short time at a very high speed through the movement of the injection punch under the action of high pressure, and the casting is crystallized and solidified to obtain the casting. &nb...

Zinc die castings are widely used, but due to the very active chemical properties of zinc materials, they need to be used for surface treatment. Baking paint and spray painting are commonly used surface treatment processes for zinc die castings. So what are the differences between them? First, the d... Read More
1. Malleable cast iron is a kind of cast iron obtained by graphitizing annealing treatment of white cast iron. Because the graphite in malleable cast iron is flocculent, it has little effect on the cutting of the matrix, so its mechanical properties are higher than gray cast iron, wear resistance an...
