We specialize in providing high-quality stainless steel wire mesh solutions for the plastic industry, including plastic extrusion, injection molding, and recycling. Our mesh products, made from premium 304 and 316 stainless steel, deliver superior filtration performance, durability, and heat resistance. Whether you need standard mesh rolls or custom filter discs, we support plastic manufacturers in improving product quality, reducing downtime, and optimizing production efficiency. Trusted by global clients for precision and reliability, we are your expert partner in industrial mesh solutions.
In plastic processing, impurities in raw materials or melt can negatively impact the finish and strength of the final product and even damage the equipment. Stainless steel wire mesh plays a crucial role as a stable, durable, and efficient filtration material in addressing these challenges.
1. Excellent Heat Resistance: Withstands melt processing temperatures between 200℃ and 350℃, making it suitable for a wide range of thermoplastics.
2. Superior Corrosion and Oxidation Resistance: Endures exposure to plastic additives and cleaning agents, especially effective with halogenated or organic acid-based plastics.
3. High Strength and Deformation Resistance: Maintains structural integrity under high-pressure extrusion, extending service life.
4. High Filtration Precision: Offers uniform mesh size and can be customized for different melt filtration needs.
5. Easy to Clean and Reusable: Supports cleaning methods like burning and ultrasonic cleaning to reduce usage costs.
● Plastic Extrusion Filtration Systems
- Purpose: Filters impurities in plastic melt, enhancing product purity.
- Location: Installed between the extruder screw and the mold.
- Materials: 304, 316, 316L, Inconel 600/601, Monel.
- Forms: Multi-layer filters, packs, disc screens.
- Layers: Single to five layers (≥ three layers recommended).
- Application: Widely used in PE, PP, PVC extrusion equipment.
● Automatic/Manual Screen Changers
- Purpose: Allows filter replacement without halting production.
- Features: High-strength, heat-resistant mesh with accurate mesh count.
- Location: Installed at the front of the extruder head.
- Materials: 304, 316, 316L, Inconel.
- Forms: Disc, rectangular, welded, or customized filters.
- Layers: Single to five layers (≥ three layers recommended).
● Melt Filtration for Injection Molding and Film Blowing
- Purpose: Removes particles and impurities, improving clarity and surface finish.
- Location: Typically located in front-end melt filters of high-end equipment.
- Materials: 304, 316, 316L, Inconel.
● Raw Material Pretreatment and Particle Screening
- Usage: Screens out large foreign particles in the feeding or mixing process.
- Advantages: Uniform mesh, reusable, and clog-resistant.
- Applications: Primary particle screening, post-granulation, additive/masterbatch screening, recycling material sorting, vibrating screens, hot cutting granulation systems.
- Materials: 304, 316, 316L.
| Plastic Type/Application | Material | Weave Type | Mesh Range |
| PE / PP / PVC standard plastics | 304 | Plain Weave | 20–100 |
| Plastics with flame retardants or additives | 316 | Plain Weave, Twill Weave | 60–150 |
| High-precision extrusion (medical, optical films) | 316L | Twill Weave, Plain Dutch Weave | 100–200 |
| High-temp engineering plastics (PEEK / PPS / LCP) | Inconel 600 | Twill Dutch Weave | 150–300 |
| Strong acid/alkali plastics (e.g., fluorinated plastics) | Monel 400 | Plain/Reverse Dutch Weave | 80–150 |
| Application / Plastic Type | Layers | Recommendation |
| PE, PP standard extrusion | Single layer | Cost-effective, easy replacement. |
| PVC, EVA cable jackets | Single layer | Lower filtration demand, prioritize quantity and replacement ease. |
| Masterbatch, recycled, filled plastics | Multi-layer | High impurity levels require durable filters; use 3–5 layer sintered mesh. |
| PET, PA6, PA66, PC precision extrusion | Multi-layer | Optical/transparency requirements, long operation time. |
| PEEK, PPS engineering plastics | Multi-layer | High temp, pressure, corrosion resistance; long-term continuous use. |
| Injection molding nozzle, filter plate | 1–2 layers | Compact space, fast install; welded disc filter fits standard holders. |
| Blown/cast film melt filtration | Multi-layer | Demands high filtration uniformity and pressure stability. |
Stainless steel wire mesh is not chosen for its low cost but for its reliability and performance. It effectively addresses critical issues in plastic production such as impurity control and melt stability, leading to higher output, reduced downtime, and superior product quality.
