Cement dumbbells have a variety of names, such as: Environmental dumbbells, plastic coated dumbbells, sand filled dumbbells, and vinyl dumbbells.
The shell is made of HDPE material and is blow molded. Then, sand, iron sand and other cement concrete are poured through the cover of the plastic shell and cleaned after solidification.
Our company uses cement concrete with uniform mixing and filling. The filling is compact. After solidification, the product has high strength, fall resistance and no abnormal sound. There are plastic packages outside, so it is not easy to damage the floor tiles and floors after accidental falling.
In the market, many dry sand and cement are directly mixed and filled. With this process, water, cement and sand cannot be mixed and solidified sufficiently and uniformly, resulting in poor strength of products and abnormal noise caused by collision of sand and stone.
