JWELL Extrusion Machinery Co. Ltd.

The screw and barrel are the core power components of rubber and plastic processing equipment, such as plastic extruders and injection molding machines. Their precise coordination enables efficient completion of key processes such as raw material transportation, melt plasticization, and pressurized extrusion. Their performance directly determines product quality and production efficiency. JWELL, with its own specialized metalworking and heat treatment nitriding workshops, independently controls the entire process, from precision machining to surface hardening, providing high-quality, stable, and durable screw and barrels for extruders.

  • Film Die Series
    This die adopts extended v-shaped manifold flow channel, triangular split flow technology and special steady flow structure. Effectively reduce the "M" or "W" shape flow during the extrusion process. Easy to connect with existing equi pment. The mold is equipped with an automatic adjus tment sys tem. During the production process, the expan- sion bolts are automatically fine-tuned at the same time, and the feedback data is automatically reciprocated by the thickness measurement equip- ment to quickly adjust the product accuracy.

  • Counter-Ratate Parallel Twin Screw
    The screw of the series consists mainly of two parallel cylindrical screws, which rotate to the opposite direction. Parallel double screw rotational speed is low, less heat, shear stability of the materials in the barrel, uniform, screw for material conveying ability is strong, have good exhaust effect at the same time, is conducive to the stability of product quality.
