ABA Three Layer Blown Film Machine
In this ABA three layer blown film machine, bi-metal alloy steel which contains 15% Tungsten carbide makes the barrel and screw particularly robust. This hardness ensures that they have a longer life expectancy by no less than 5 years.
Taiwanese engineering is behind the design of the screw, particularly the feeding and mixing parts. These components have substantially increased the productivity of the machine and the quality of the film.
ABA design is a great way to reduce material costs and increase productivity, ultimately resulting in increased profits. Additionally, with this design we can mix up to 50% calcium carbonate in the B screw.
We use top-tier components, such as a Siemens main motor, an LS inverter, and an Omron temperature controller. These components ensure high quality and outstanding performance.
