Extruder Single Screw Barrel

Zhoushan Nanhaiya is a leading manufacturer of screw barrel in China for more than 20 years. We provide one-stop solutions in the plastic-related fields for global enterprises. OEM ODM is supported.

Why choose Nanhaiya?

1. High-quality Raw Material

We use high quality raw materials which are directly purchased from steel mills,select the high-level steel, which, through forging and extrusion, achieves better density and toughness.

2. Advanced Bimetallic Craft

We use imported nickel-based alloy + tungsten alloy. The length of the alloy is over 400mm, and the depth is 2 - 3mm. Alloy hardness can reach HRC58-65. The alloy can be customized according to customers' requirements to achieve better wear and corrosion resistance, thus extending the service life of the screw and barrel.

3. Fast Delivery

For standard-type screws, we have established a standardized inventory system to achieve fast delivery within 24-48 hours; for customized products, we commit to a delivery cycle of 30-40 days. Customers can keep track of the real-time order progress through timely production status updates.

4. 24-hour After-sales Service

We provide full-life-cycle after-sales services, including installation guidance, troubleshooting, and regular maintenance recommendations. Our after-sales team offers 24-hour response to ensure prompt resolution of customer issues and minimize downtime losses to the greatest extent.

5. Excellent Cost-performance

For products of the same quality, we compete on price; for products at the same price, we excel in quality. Nanhaiya Screws boast ultimate cost-effectiveness, making them your ideal choice.

Extruder Single Screw Barrel

Product details and application

The core advantages of extruder single screw barrel lie in their high cost-effectiveness and ease of operation and maintenance, making them particularly suitable for low-to-medium complexity plastic processing scenarios. They achieve uniform plasticization for single-variety raw materials such as PE, PP and PVC, which can meet the quality requirements of mainstream products like pipes and films. Moreover, they can realize 24-hour continuous extrusion without frequent shutdowns for adjustments, making them ideal for scenarios requiring long-term stable production such as pipe manufacturing and cable coating, thus ensuring production efficiency.

Technical Parameter

Single screw extruders are mainly concentrated in fields where there is low demand for material mixing, and emphasis is placed on cost-effectiveness and operational convenience. Specific scenarios include:

1. Pipe and profile extrusion: Such as PVC drainage pipes, PPR water supply pipes, and plastic door and window profiles. These products have high requirements for raw material purity and do not require complex mixing, making them suitable for the stable conveying characteristics of single-screw extruders.

2. Film production: Such as blown PE agricultural films and packaging films. Single-screw extruders can stably control melt pressure to ensure uniform film thickness.

3. Cable coating: Used for coating the insulation layers (e.g., PVC, PE) of wires and cables. As this process requires rapid and continuous extrusion of melts, the efficient conveying capacity of single-screw extruders can meet the demand.

4. Extrusion of simple products: Such as plastic rods, sheets, special-shaped profiles, and granulation of recycled plastics (single-type recycled materials). Single-screw extruders can achieve basic processing at a relatively low cost.
