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.

Extruder

Adopts accumulatorfree continuousextrusion structure with highefficiency screw for uninterrupted melt output without retention or degradation, delivering stable and uniform plasticization. Optional singlelayer or doublelayer coextrusion module, compatible with HDPE and highratio regrind blending. Independent zoned temperature control supports viewstrip line function for highspeed mass production of mediumsmall packaging drums.

Diehead

Straight through continuous flow die head with compact structure for easy disassembly, cleaning, color and material change. Equipped with parison wall thickness point adjustment function to compensate parison sag and optimize wall thickness distribution at neck, bottom and handle positions. Zoned precise temperature control keeps melt temperature stable under continuous extrusion.

Parison Gripping & Transfer Mechanism

Core parison gripping transfer unit. When parison reaches target length, gripper grabs and cuts tubular parison, then transfers it to clamping station, different from conventional moving mold solution. Servo driven motion ensures fast response and high positioning accuracy. It reduces sag interference caused by hot parison self-weight, stabilizes parison feeding posture, improves part weight consistency and cuts flash waste.

Clamping & Control System

High strength clamping frame provides sufficient clamping force for various 15 50L drum molds. Mold movement is time sequence interlocked with parison gripping transfer mechanism. Integrated control system supports editable wall thickness profile and multi product recipe storage. Real time monitoring for extrusion temperature & pressure and mechanism status, with complete alarm and safety interlock. It can connect with unloading manipulator and flash trimming auxiliary for fully automatic operation.
