Spring
Steel spring, also called compression spring, is made of spring steel wire. It is a coil spring that bears axial pressure. There is a certain gap between the coils of the compression spring. When it is subjected to an external load, the spring contracts and deforms to store deformation energy. It is widely used, reliable and durable.

Product Advantages
Vibrating feeder springs are one of the necessary accessories for vibrating motor feeders. The special springs for feeders produced by Shunhua are made of high-quality steel and have perfect sizes. They can be widely adapted to different brands of feeding equipment.
Lost foam casting process

Our company adopts a new lost foam casting process. This technology is a new process with almost no margin and accurate molding. This process does not require mold taking, no parting surface, and no sand core, so the castings have no flash, burrs, and draft slopes. degree, and reduces dimensional errors caused by core combination. The surface roughness of castings can reach Ra3.2 to 12.5μm; the dimensional accuracy of castings can reach CT7 to 9; the machining allowance is up to 1.5 to 2mm. Compared with traditional sand casting methods, the machining time can be reduced by 40% to 50% , short production cycle.
