EQUIPMENT
01.
Shot Blasting Machine
The shot blasting process uses 2 of the most advanced crawler-type shot blasting machines in China for rough and fine blasting respectively. Driven by the crawler movement, the castings tumble in a manner similar to that in a rotating drum. The shot blasting process is used to remove sand adhesion and oxide scale from the workpiece surface. After shot blasting, the surface impurities of the workpiece are removed, and a uniform surface quality is achieved.
02.
Core Vibration Machine
This machine adopts a pneumatic impact method to vibrate and strike the workpiece, causing impact acceleration and cavity resonance in the workpiece, generating peeling stress at the sand layer or two-phase interface, thereby achieving the sand removal effect and removing core sand from the internal cavity and sand adhesion on the surface. It adopts German F+K vibration units, ensuring the sand cleaning effect.
03.
Shot Peening Machine
There are currently 3 JCK-1010F sand blasting cleaning machines. The castings after core vibration are cleaned in the internal cavity flow channels by the shot peening machine. The high-speed flowing steel shot stream removes core sand, coating, and oxide scale adhering to the inner walls of the flow channels, making the flow channels clean inside.
