If you are also interested in sand casting technology welcome to learn about our production line.

Compared with other casting methods, such as precision casting, metal mold casting or die casting, sand casting is indeed a relatively cheap casting method that is suitable for a variety of product shapes and production requirements.

Sand casting is mainly divided into three types: water glass sand, resin sand, and coated sand. The main difference between them is that they use different binders and curing agents, so their production processes are different.

During "Sand casting", first place the lower mold on a flat plate, put a sand box, fill the sand and scrape it tightly. After the lower mold is made, turn the sand mold 180 degrees, put the upper mold, sprinkle the parting agent, put the sand box, fill the sand and make it tight and flat, turn the upper sand box 180 degrees, take out the upper and lower molds respectively, then turn the upper mold 180 degrees and put it together with the lower mold. The sand mold is made and waiting for pouring. This process is commonly known as "sand casting".

The first function of engine flywheel is to store energy. When the engine is working, the flywheel stores energy and inertia so that the crankshaft can continue to rotate. Because the inertia of the flywheel rotation is large, it can reduce the fluctuations in engine speed and make the operation more stable. Without the cushioning effect of the flywheel, the speed of the engine will fluctuate significantly, and the power output will be incoherent. This makes the flywheel an indispensable component in a single-cylinder or multi-cylinder engine.

In the previous article, we focused on the cause of the fracture of the slip yoke casting. It is also very important to master the correct preventive measures to minimize the risk of the connecting rod breaking. This not only guarantees construction safety, increases the service life of the connecting rod, but also significantly reduces the cost of equipment use. In order to prevent the automotive driveline slip yoke from breaking, what should we do? This article will focus on the preventive measures for the fracture of the slip yoke casting.

On the construction site, the excavator that was working suddenly made an abnormal noise, and immediately stopped for inspection and found that the automotive driveline slip yoke had broken. This kind of situation is very common in the use of construction machinery, but every fracture may bring serious safety risks and maintenance costs.
