200 Liters Rotational Molding Mold No Welding Seamless

Two hundred liters of round bucket mold for making plastic products.

Rotational molding involves a heated hollow mold which is filled with a charge or shot weight of material. It is then slowly rotated (usually around two perpendicular axes), causing the softened material to disperse and stick to the walls of the mold. In order to maintain even thickness throughout the part, the mold continues to rotate at all times during the heating phase and to avoid sagging or deformation also during the cooling phase. The process was applied to plastics in the 1950s but in the early years was little used because it was a slow process restricted to a small number of plastics. Over time, improvements in process control and developments with plastic powders have resulted in increased use.

Plastic products have strong impact resistance, high tensile strength, good oxidation resistance and aging resistance. Compared with traditional anti-corrosion storage tanks, it is inexpensive and cost-effective; plastic has the characteristics of internal and external corrosion and can be placed in a strong corrosive environment; and has excellent chemical resistance, can withstand most substance solutions, except for a few that can make it Swelling solution.

The drum has beautiful appearance, smooth inside and outside, no welding seamless, light weight, good strength, impact resistance, corrosion resistance, non-toxic and tasteless, and convenient transportation. It can be used for hot filling, and the general temperature should not exceed 60°C.

The rotomolding mold has no hot runner, cooling groove, etc., and the structure is relatively simple; the product molding process is pressureless molding, so the mold wall thickness is relatively thin and the structure is simple.

Rotomolding products have good one-time molding integrity, relatively high material utilization rate, no welding, and no leakage.

Mold production time and manufacturing costs are relatively small, and maintenance and repair are relatively easy. Molds of different sizes and different tonnages can be customized according to requirements.
