Process Know How
Combining practical processing expertise with advanced blow molding technology, JWELL provides reliable solutions tailored to different materials, products, and production requirements. From process setup and material optimization to stable mass production, our know-how helps customers achieve consistent quality, efficient operation, and improved production performance.
Equipped with a dedicated accumulator head structure with an internal melt storage cylinder and hydraulic injection piston. The screw performs continuous plasticizing and melt feeding, while the accumulator stores melt quantitatively and discharges materials rapidly via one-stroke injection. This design delivers large-volume, high-weight parisons instantly without parison sag, perfectly suitable for thick-walled and large-scale hollow products. The optimized spiral flow channel ensures uniform melt distribution, stable plasticization quality and convenient material and color replacement.
Adopts heavy-duty fixed clamping structure with a large mold mounting dimension of 900*900mm. It features high rigidity, strong locking force and excellent structural stability, effectively resisting high blow pressure during molding. The large mold opening stroke and spacious mold installation space support the production of large-capacity hollow products with complex structures.
Configured with a dedicated servo-driven pick-up manipulator for automated product demolding and handling. It replaces manual operation to realize stable and high-speed product picking, effectively reducing manual errors and labor costs.
Integrated intelligent control system B&R300/ MOOG200&SIEMENS with simple operation and storable process formulas. The high-precision parison wall thickness control system automatically corrects wall thickness deviation. Adopts servo closed-loop control for precise motion, equipped with fault alarm and safety interlock functions to realize high-level automation production.
