1 .The machine use continuous rotation system with multiple safety protection devices to ensure the high speed preform feeding. 2 .The preform feeding without turning device,simple structure,convenient maintance, reduce cost of spare part change. 3 .The heating pitch between the preforms is small,effectively using the heating space of the lamp tube,and improving the heating efficiency enery saving by variable pitch structure. 4 .The water runs directly through the heating channel with air cooling system to protect preform neck from deformation. 5 .Optimize oven air draft and preform surface cooling.Reversible heating box make it more easy to change lamp. 6 .Mould closing adopts CAM linkage,no chain plate pin shaft small size, long service life. 7 .The stepping servo motor ensure high-speed operation and accurate positioning. 8.Servo moto is used to drive the stretching and blowing station,equipped with high speed precision blowing valve set to achieve high production requirements.
