5ML-10L double station automatic blow molding machine

The 5ML-10L double station blow molding machine is different from the single station machine in that it has one additional station with high-precision linear guide, covering three major series of PTB55D, PTB70D, and PTB90D. The same as the single station machines, it can be used to produce a wide variety of materials, such as PE, PP, and PA. The largest capacity of the product can be 10L, and its production capacity is 60 to 70% more than the single station machine.  In accordance with different type of products, die heads can be changed to achieve multi-type production.
