Sheet making machines are mechanical equipment used to produce various sheet materials. Sheet making machines can be divided into various types based on different applications and process requirements. The following are several main categories of sheet manufacturing machines:
Calender
A calender is a commonly used sheet-making machine, primarily used to produce plastic sheets. It presses plastic raw materials into sheets with uniform thickness and smooth surface through a series of calendering and forming operations. The calender usually consists of a feeding device, a multi-roller calender unit, a cooling device and a winding device.
Hot Press
A heat press is a piece of equipment used to produce thermoplastic sheets. It heats the plastic raw material to above the melting point, and then presses the plastic raw material into the required sheet shape through hot pressing and cooling operations. A hot press usually consists of a heating device, a pressure device and a cooling device.
Cold press
A cold press is a piece of equipment used to produce rigid plastic sheets. It presses plastic raw materials into sheets with uniform thickness and smooth surface through cold pressing and forming operations. Cold presses usually consist of a pressure device and a cooling device.
Thin film unit
Thin film unit is a piece of equipment used to produce film materials. It converts plastic raw materials into film materials through a series of stretching and cooling operations. The film unit usually consists of a feeding device, a stretching device, a cooling device and a winding device.
The above are several major classifications of sheet manufacturing machines. Each type of equipment has its specific application and process requirements. When choosing a suitable sheet manufacturing machine, you need to make a selection based on actual production needs and process conditions.
