Auto Casting Film Die Plastic Extrusion Line V Shape Water Drop Flow Channel Film Die Series

Auto Casting Film Die Plastic Extrusion Line V Shape Water Drop Flow Channel Film Die Series

Descriptions :

The die head adopts and extension V shape water-drop type flow channel, with the shunt technology and special triangle structure. To composite layer and improve the precision of the extrusion process to eliminate “M” and “W” shape flow patterns effectively.

The upper die lip using push-off type manual fine-tuning and automatic fine-tuning one piece die lip, manual adjustment range is ±1 mm, automatic adjustment range ±300um. The automatic die lip adjustment control parts, we use currently very advanced fully closed loop control system and the automatic gauging system makes the product thickness in ±2% precisely, on-line thickness gauge is automatic continuous detecting scanning frequently, can shows the very real-time accurate thickness tolerance of the products.

Through computer program processing the data, feedback to special die lip adjusting bolt thermal expansion and to realize the opening of the die lip thickness for automatic fine-tuning, fast and effective control product thickness precisely. And we have good die head scalability, according to customers’ requirements, matching with different “inside blocking type width adjusting device” or “the outer blocking type with adjusting device”, in order to meet customer’s needs to more efficient production.

This die head suit for production under 5000mm, thickness between 0.06-0.18mm, CPP, PE, EVA, PVC, PET, PVB, PA etc. single-layer or multi-layer films.
