High Output Barrier Screw
Screws
High Output Barrier Screw
Manufacturer:
Rajlaxmi Industries
Origin:
Ahmedabad, Gujarat, India
Delivery:
Pan India & Global Export
Product Overview
Engineered Barrier Screws with separate melt and solid channels delivering 20% to 35% higher throughput with low melt temperature.
Our Barrier Screws separate solid plastic pellets from molten resin through dual-flight geometry. This guarantees complete melting, eliminates unmelted gel particles, improves color dispersion, and delivers substantially higher output at lower melt temperatures.
Material Grades
EN41B Nitro Alloy Steel with optional Bimetallic Flight Inlays
Hardness Rating
Nitrided 68 HRC / Stellite Flight 60 HRC
Key Technical Advantages
- 20% - 35% higher production throughput compared to standard screws
- Eliminates unmelted gels in blown film and pipe extrusion
- Uniform melt temperature preventing thermal degradation of polymers
