The Production Process of Rotational Molding

You are probably asking, “how does rotational moulding work?” Well, the process begins by loading a powdered plastic material, mostly polyethylene, into a hollow mold. The manufacturer then places the cast in a rotomolding machine with temperature ranging between 260°C – 370°C based on the material.

The mold then slowly rotates in both a vertical and horizontal axis. Afterward, the polymer melts gradually and adheres to the mold’s inner surface. The final step involves cooling the molten material by using a fine mist of water or air. Once it adequately solidifies, you can now unload the formed object.

Repeat the procedure as much as required, and if any mold splits appear, remove it via trimming. It would be best to subject the objects to leak tests to check on the quality. At this juncture, you can also add some holes, screws, and slots where necessary.

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.
