The die head adopts an extension V shape water-drop type flow channel,with the shunt technology and special triangle stabilize structure. To composite layer and improve the precision of the extrusion process to eliminate 'M' shape and 'W shape flow patterns efectively. The upper die lip using push-off type manual fine -tuning + automatic fine-tuning one- -piece die lip, manual adjustment range is士1mm, automatic adjustment range 土300um; About the automatic die lip adjustment control parts ,we use crrently very advanced flly closed loop control system and the automatic gauging system makes the product thickness int 2% peisely, on-line thickness gauge is automatic continuous detecting scanning frequenty, can shows the very real-time accurate thickness tolerance of the products. Through computer program processing the data, feedback to special die lip .adijusting bolt thermal expansion, and to realie the opening of the die lip thickness for automatic fine-tuning, fast and efective control product thickness precisely. And we have good die head scalability, according to customers' needs , matching with iferent "inside blocking type with adjusting device' or "the outer blocking type width adjusting device', be better satisfied customer' s needs to more fficient production.

The die head suits for production under 5000mm,thickness between 0.06 -0.18 mm CPP, PE, EVA, PVC, PET, PVB, PA, single-layer or mutilayer films.
