Extrusion system is a crucial part of multi-layer co-extrusion blow molding machine, TONVA adopts the most advanced parison control system to adjust the product wall thickness uniformly, special design and treatment of the die head internal flow channel to make the product in the production process, no coke material and achieve faster color change effect. At the same time, we choose 40Cr material for the core rod and after tempering, fine turning, polishing, hard chrome plating and other processes to ensure the quality of the finished product, to meet the packaging of CO₂, O₂ or gasoline barrier performance requirements. TONVA advance multi-layer blowing technology has been widely used in pesticide packaging, chemical packaging, food packaging, cosmetic packaging, pharmaceutical packaging and other industries. Our comprehensive service system can tailor one-stop blow molding solutions for each user. From raw material ratio, each layer configuration, wall thickness control to finished product testing each step to achieve accurate automation, intelligent control greatly reduce labor costs and improve production efficiency.
