How To Choose A Rotational Molding Machine

Rotational molding machine is a plastic machine that uses the principle of rotational molding to form plastics.Types of rotational molding machines:

1. According to the heating method, it is divided into gas direct fire heating, hot box heating (electricity, oil, gas, coal heating), infrared heating, thermal medium heating, etc.;

2. According to the rotation type, it is divided into swing type and double-axis rotation type;

3. According to the movement mode of the arm, it is divided into fixed arm, pendulum type, shuttle type and turret type (free arm turret type in which each arm moves freely and non-free arm turret type in which each arm is connected together and moves together). ;

4. According to the number of arms, it is divided into single arm, two arms, three arms and four arms. . . wait;

5. According to the hot box, it is divided into dynamic hot box and fixed hot box.

Commonly used and common rotational molding machine models are:

1. Single-arm direct fire heating swing type;

2. Single-arm hot box heating swing type;

3. Single-arm hot box heating dual-axis rotary type (moving hot box and fixed hot box);

4. Two-arm hot box heating biaxial rotary type (two types of parallel movement and vertical movement) (moving heat box and fixed heat box);

5. 3-arm or 4-arm hot box heating free-arm turret type (moving hot box and fixed heat box);

6. 3-arm or 4-arm hot box heating non-free arm turret type (moving hot box and fixed heat box).

Rotational molding machine selection:

Common indicators used to describe rotational molding machines: type + number of arms + maximum rotation diameter (or rotation diameter) allowed by the mold + thermal energy method, etc.

1. Determine the size of the rotation diameter of the equipment and the type of equipment based on the size, type and output of the largest product planned.

2. Determine the type of equipment, heating method, and degree of automation based on the expected investment size.
