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.

Engineered for diverse production needs, this machine series supports a wide variety of product shapes, sizes, and applications. Its flexible design allows manufacturers to efficiently produce different hollow plastic products while ensuring consistent quality and reliable performance.
Designed for producing durable jerrycans and stackable containers in different shapes and capacities. The machine provides stable molding performance and consistent wall thickness to meet demanding requirements for strength, stacking, and reliable daily use.

Suitable for manufacturing plastic fuel tanks with complex shapes and functional requirements. Precise material distribution and flexible machine configurations help achieve consistent wall thickness, structural integrity, and reliable production quality.

The BM30/50 Accumulating Type Blow Molding Machine is engineered to deliver stable extrusion performance, flexible processing options, and reliable operation. With customizable configurations, intelligent controls, and efficient material handling, it provides manufacturers with a versatile solution for producing a wide range of medium and large hollow plastic products.
