Polyethylene Sodium Chloride Tanks feature plastic's corrosion resistance, as well as benefits such as one-time molding without welds, smooth appearance, smooth inner walls, impact resistance, high-temperature and low-temperature resistance, high strength, no leakage, acid and alkali resistance, resistance to various organic and inorganic acids, various solutions, and long service life.

The rotational molding mold is simple and a vacuumless molding mold. Characteristics of the rotational molding mold: thin walls, lightweight. The mold consists of two halves, the upper and lower, which are secured with clamps. To exhaust the gas formed in the mold cavity and prevent deformation of the product, exhaust holes are provided in the mold.
