Anping Xinye Metal Wire Mesh Products Co., Ltd, located in the wire mesh capital of China – Hengshui, Hebei, has been a trusted manufacturer of precision filtration components for over a decade. Our Stainless Steel Extruder Filter Screen for Plastic Granule Melt Filtration is engineered to remove contaminants from molten plastic during extrusion, ensuring high-quality output and consistent production. Whether you are processing polyethylene, polypropylene, nylon, or recycled materials, this filter screen delivers reliable performance and long service life.
Designed for use in single-screw and twin-screw extruders, our filter screens are available in a wide range of mesh sizes, wire diameters, and diameters to fit standard breaker plate assemblies. The use of premium stainless steel wire ensures excellent corrosion resistance, high tensile strength, and resistance to deformation under high temperature and pressure. This product is an essential component for any plastic recycling, compounding, or pelletizing operation.
Below we detail the key features, technical specifications, and benefits that set our filter screens apart—helping you achieve better melt quality, reduced downtime, and lower operational costs.
Key Features & Advantages
- Premium Stainless Steel Construction: Made from AISI 304 or 316 stainless steel, offering excellent resistance to oxidation, acids, and alkalis encountered in plastic melt.
- Precise Mesh Opening: Available from 20 mesh to 500 mesh, ensuring accurate filtration of contaminants while maintaining high flow rates.
- High Strength & Durability: Each screen is woven with uniform wire tension and then heat-treated to eliminate internal stress, preventing screen rupture under high pressure.
- Custom Fit for Any Breaker Plate: Screens are cut to exact diameter (e.g., 50mm, 100mm, 150mm, or custom sizes) and can be supplied with or without edge welding/tinning for easy installation.
- Excellent Temperature Tolerance: Withstands continuous operating temperatures up to 400°C, suitable for most engineering plastics.
- Consistent Micron Rating: Strict quality control ensures each screen meets the specified micron rating, providing repeatable filtration performance.
- Recyclable & Eco-Friendly: Stainless steel screens can be cleaned and reused multiple times, reducing waste and consumable costs.

Frequently Asked Questions
Q1: What mesh size should I choose for my plastic extrusion?
A: The ideal mesh depends on your material and desired purity. For example, 20–40 mesh is used for coarse filtration of recycled flakes, while 80–150 mesh is typical for virgin pellets. For fine filtration of masterbatch or engineering plastics, 200–500 mesh is recommended. We can help you determine the optimal combination.
Q2: Can these screens be used for high-temperature plastics like PEEK or PTFE?
A: Our stainless steel screens can withstand temperatures up to 400°C. For PEEK (processing ~350°C) and PTFE (~350°C), they are suitable. For ultra-high temperature applications exceeding 400°C, please consult our technical team for alternative materials.
Q3: Do you offer multi-layer screen packs (stacked screens)?
A: Yes, we can supply pre-assembled screen packs with different mesh layers (e.g., 20/40/60/80) to achieve progressive filtration. The packs can be spot-welded or held together with a metal ring to simplify handling.
Q4: What is the typical lead time for custom-sized screens?
A: For standard sizes (50–200mm diameter), we ship within 3–5 working days after order. Custom dimensions or special edge finishes may require 7–10 working days. Express shipping is available upon request.
Q5: How do I clean and reuse a stainless steel filter screen?
A: Screens can be cleaned by burning off residual plastic in a furnace at 400–500°C, followed by ultrasonic cleaning or water jet. Alternatively, chemical cleaning agents can be used. Avoid using abrasive tools that may damage the mesh.
Q6: Can you provide a sample before I place a bulk order?
A: Absolutely. We offer sample screens for testing. Please contact us with your required mesh size, diameter, and quantity. Sample cost is refundable upon bulk order placement.
Q7: Are your screens compatible with all extruder brands?
A: Our screens are designed to fit standard breaker plates. If you provide the inner diameter of your breaker plate recess and the required screen diameter, we can match it precisely. We have supplied screens for Brabender, Coperion, Leistritz, Davis-Standard, and many other brands.
Q8: Do you have any quality certifications?
A: We follow strict internal quality control procedures. While specific certifications such as ISO 9001 are not mentioned in our public profile, we are happy to share our quality inspection reports and test results upon request. Our production process is continuously monitored for consistency.
