When customers search for “custom screw barrel”, they are not simply looking for standard parts—they need personalized engineering solutions that match their specific materials, production goals, and machine configurations. A customized screw and barrel can dramatically improve melt quality, output stability, and product consistency.
At Zhoushan Juyuan Machinery Co., Ltd., we design and manufacture custom screw barrel systems for extrusion and injection molding machines used in PVC, PE, PP, PET, TPU, ABS, PC, and high-glass-fiber applications. With over 20 years of professional experience, we provide OEM-level precision and long service life that global manufacturers depend on.
Why Choose a Custom Screw Barrel Instead of a Standard One?
1. Improved Material Performance
Different plastics require different screw geometries.
For example:
- PVC needs gentle plasticizing
- PET and PC require strong shear
- 30–50% fiberglass needs wear-resistant flight design
A custom screw barrel ensures optimal melting, mixing, and output stability.
2. Higher Output & Better Energy Efficiency
By adjusting:
- Compression ratio
- Mixing section
- L/D ratio
- Flight depth
A tailored screw can increase productivity by 10–40% compared to a standard design.
3. Longer Service Life
Custom solutions can include:
- Bimetallic alloy liners
- DC53 / SKD61 tool steel
- Wear-resistant flight hardfacing
These upgrades significantly reduce downtime and maintenance cost.
4. Perfect Fit for Old or Imported Machines
Even if the original brand has discontinued the model, we can design custom parts based on:
- Drawings
- Samples
- Measurement photos
- Machine nameplate
Helping you keep your production line running.
