1. Pneumatic：apply pneumatic cylinders to control jigs and hot platen motion and force pressure during hot plate melting and welding. The advantages of pneumatic hot plate welder is lower machine manufacturing cost, fast motion speed. Pneumatic hot plate welder can meet the most of welding requirement.
2. Hydraulic: apply hydraulic cylinders to control jigs and force pressure during hot plate melting and welding. Its advantages is can provide very high pressure during hot plate welding which is applied to finished hot
plate welding requests high strength.
For the fast motion, normally,machine applies pneumatic system to control the motion of hot platen.
3. Servo Motor: apply servo motor systems to control jigs and hot platen motion and force pressure during hot plate welding & welding. Servo hot plate welding is with advantages of high control precision, fast motion speed,
and can realize the steps control of hot plate welding process, meeting hot plate thermoplastic joining to in high requirement, especially perfect to lower temperature welding or non-contact heat welding.
Because the developing of demand, servo hot plate welding machine is more and more welcomed by market.
4. Half Servo (Servo & Pneumatic )Hot Plate Welder: apply servo motor system to control the motion of jigs and apply pneumatic cylinders systems to control the motion of hot platen. Machine apply servo motors to control jigs motion to ensure its fact action, precision control in steps process, and on the other hand, because the speed control accuracy of hot platen is not very important to most of hot plate welding, applying pneumatic system to control hot platen by which ensure fast hot platen motion speed while achieves economical machine manufacturing cost.
