Abstract: This article introduces the process characteristics and product applications of the bottom blown
water-cooled blow molding method, analyzes the current situation and problems of the equipment, and
also introduces the process flow and key technologies of the eleven layer coextrusion bottom blown water-
cooled high resistance diaphragm unit. The unit adopts a disc set combination head to ensure high-quality
composite, shorten the material thermal process, and meet the processing requirements of various formulas;
Adopting a wind temperature automatic wind ring and thickness measurement control system to improve the
uniformity of film thickness; Adopting vacuum water ring to meet wide width production and increase output;
Adopting low resistance clamps and low swing rotation traction to improve the quality of the membrane
surface; By adopting intelligent collaborative control technology, precise closed-loop control of the thin film
production process has been achieved.
Key words: downward blowing; multi layer coextrusion; disc set combination machine head; vacuum
water ring; splint board
