There are basically two forms of forming machine for thermoplastic sheet: sheet feeding type and sheet feeding type. Sheet and coil feeding thermoforming machine is used to feed the sheet in the form of a roll, or directly connected with the sheet extruder into a production line. Plastic machinery sales of single-chip feeding type thermoforming machine is due to the pre - cut sheet material into the name.

Continuous sheet and coil feeding thermoforming machine is very popular, which can produce high quality products at high speed and supply according to mould specification. The most popular specifications are 60×60, 90× 90,125 ×106cm and so on. This type of thermoforming machine is often designed with a heating furnace that is 3 to 4 times the length of the longest mold. Most furnaces are electrically heated and installed on shelves that can be removed from the sheet conveying system. Oven has C type frame type and door type two main forms. The hot forming system adopts hydraulic or mechanical drive. Plastic machinery sales of single-chip feeding type thermoforming machine can be divided into rotary and shuttle two types. Rotary thermoforming machines are often used in mass production. Common three station standard thermoforming machine, station rotation degree of 120°; There are also four hot forming machine, that is, add a heating station. Shuttle thermoforming machine has a forming station, the sheet is clamped on the clamping frame, and then moves back and forth over the heating furnace. Also designed into two molding station and a drying furnace composed of a double station thermoforming machine. This kind of hot forming machine has a wide range of processing adaptability.
