Product Description

Rotational Molding Plastic Water Tank Machinery Production Process
Automatic Plastic Product Manufacturing Equipment
Rotational molding is a high-temperature, low-pressure plastic molding process that utilizes heat and biaxial rotation to produce hollow, one-piece parts.

Rotational Molding Equipment for Plastic Furniture Tables and Chairs

During the heating stage, the mold rotates slowly in two planes (biaxial rotation).

The process includes four distinct stages:

A certain amount of polymer (usually in powder form) is loaded into the mold.

The mold is heated in an oven while rotating until all the polymer melts and adheres to the mold walls. The hollow part should be rotated by two or more axes at different speeds to avoid the accumulation of polymer powder.

Air cooling of the mold. The polymer must be cooled to solidify and be safely handled by the operator. The part shrinks away from the mold during cooling, facilitating part removal.

Part removal.

The unique design of Roto molding machines allows for uniform plastic coating within each mold.

The image on the right shows our stand-alone rotational molding machine. This is one of the most common machines in the industry. It has three arms.

This machine is a stand-alone model. Stand-alone machines can provide up to three arms that can move independently of the other arms. This allows for molds of different sizes with varying heating and thickness requirements.

It consists of an oven, a cooling chamber, and a mold spindle. The spindle is mounted on a rotating shaft that provides a uniform plastic coating within each mold.
