1.Purpose:
It is used to blow low-density Polyethylene (LDPE), high-density Polyethylene (HDPE), linear low-density Polyethylene (LLDPE) as well as other plastic compound films, and it is suitable for semi finished article cylinder material making of various T-shirt bags.
2.Function:
1. The machine body is U-steel frame, and the main machine is collocated with low-center gear decelerator, with advantages of stable transmission, large torque, and convenient repair.
2. The machine cylinder and screw adopt 38CRMOAIA alloy steel, after nitrogen treatment, it has high rigidity, good anti-corrosive performance and is rather durable.
3. During heating course, this machine can automatically control and regulate temperature according to craft requirements, with simple operation.
4. The traction device is stepless speed regulation, with broad regulation range, stable and reliable.
5. Ordered twisting, and is convenient to replace.
