How to select the type of rolling molding machine

2023-06-07 14:02

Rotational molding machine is a plastic forming machine that utilizes the basic principles of rotational molding products.

Types of rolling machines:

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

2. According to the type of rotation, it can be divided into swing type and two axis turntable type;

3. According to the method of arm movement, it can be divided into fixed fixed arm, pendulum type, shuttle type, and rotary type (two types: random arm rotary type with each arm moving freely and non random arm rotary type with each arm connected and moving mutually);

4. Divided into double arms, double arms, three arms, and four arms according to the number of arms... Etc;

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

Common and common models and specifications of rotary molding machines include:

1. Double arm straight fire heated swing type;

2. Double arm hot box heating swing type;

3. Double arm hot box heating two axis rotary table type (dynamic hot box and fixed hot box);

4. Double arm hot box heating two axis rotary table type (two types of parallel moving and vertical moving) (dynamic hot box and fixed hot box);

5. 3-arm or 4-arm hot box heating with arbitrary arm rotation vertical (dynamic and fixed hot boxes);

6. 3-arm or 4-arm hot box heating, non random arm rotating vertical (dynamic and fixed hot boxes).

Model selection of rolling molding machine:

Describe the common indicator values of the rotational molding machine: type+number of arms+allowable larger rotation diameter (or rotation diameter) of the mold+energy method, etc.

1. Based on the size, type, and production volume of the larger products to be produced in the plan, determine the size of the rotating diameter of the machine equipment and the type of machine equipment.

2. Based on the estimated project investment size, make decisions on the types of machinery and equipment, heating methods, and automation technology level.
