How to Choose a Extruder Screen Mesh?

The preferred choice is a multi-layered extruder screen pack made of 316L stainless steel mesh, employing a gradient combination structure of 20–120 mesh, and ensuring manufacturing precision in accordance with ASTM/ISO standards. This configuration not only guarantees efficient filtration while achieving stable pressure but also significantly extends service life. Furthermore, the high temperature resistance, corrosion resistance, and high strength of 316L material ensure reliability in high-volume, complex operating conditions, or extrusion of materials containing impurities, thereby reducing equipment maintenance frequency, improving production efficiency, and guaranteeing the quality and consistency of the final product.

1. What is an Extruder Screen Mesh? 

Extruder screens are essential filtration components used in the plastic extrusion process. These precision-engineered mesh screens serve as critical filtering devices that remove contaminants, impurities, and unmelted polymer particles from molten plastic as it passes through an extruder. By providing consistent filtration, extruder screens ensure the final extruded product maintains high quality, superior finish, and structural integrity.

Extruder screens provide a clean and clear extrusion for the melt filtration and plastic extrusion processing machinery. Also called polymer filter screen or melt filter screen. Extruder Screen Mesh are mainly made from high quality SS304, SS316, SS304L, SS316L meshes ranging from 4 mesh to 500 mesh, and used for plastic and rubber industry.

3. How to Choose the Wire Mesh for Plastic Recycling？

3.1 Mesh Size and Opening Dimensions

The first and most obvious factor to consider when choosing wire mesh for plastic recycling is the size of the mesh and the opening dimensions. For example, if you are processing plastic flakes, you’ll need a wire mesh with smaller openings to effectively filter out any contaminants or smaller particles that could interfere with the recycling process. On the other hand, if you are dealing with larger pieces of plastic, a mesh with larger openings may be more appropriate to allow for smoother flow.

The size of the mesh and the opening dimensions will also affect the speed and capacity of your recycling system. A fine mesh will provide a higher level of filtration, but it may slow down the process due to its smaller openings. Larger openings, while allowing for higher throughput, may miss smaller contaminants, impacting the final product’s purity.

3.2 Material Strength and Durability

The durability and strength of the wire mesh are critical considerations in choosing the right product for plastic recycling. The wire mesh will need to endure continuous exposure to heavy materials, sharp edges, chemical substances, and even extreme temperatures depending on the nature of the recycling process.

Materials like stainless steel are commonly used for wire mesh in plastic recycling because of their superior resistance to corrosion, rust, and physical wear. Stainless steel is especially suited for environments where the recycling process involves frequent contact with water or other liquids. Additionally, stainless steel meshes are known for their high tensile strength, which means they can withstand mechanical stress without breaking or deforming.

Choosing a material that aligns with the expected operational conditions will ensure that the wire mesh performs optimally over a longer period, reducing maintenance costs and downtime.

3.3 Cost Considerations

While it’s tempting to choose the most durable and efficient mesh, cost remains an important factor when selecting wire mesh for plastic recycling. Wire meshes can vary greatly in price depending on the material, mesh size, and durability. While stainless steel meshes are typically more expensive, they offer longer lifespans and better performance in demanding conditions. For operations on a tight budget, a more economical option such as galvanized steel or carbon steel may be considered, though these may require more frequent replacements and repairs.

It’s also important to factor in the long-term costs of operating a mesh with higher filtration capabilities, such as potential slowdowns in processing time or additional cleaning efforts. Choosing a wire mesh based on your budget should involve considering both upfront costs and long-term operational expenses. 

3.4 Compatibility with Other Equipment

The wire mesh you choose must be compatible with other equipment in your plastic recycling system. This includes ensuring that the mesh fits properly within the machines and can handle the materials moving through the system. For instance, the mesh must be able to integrate with conveyor belts, shredders, or washing tanks, depending on your setup.

Compatibility also extends to the wire mesh’s ability to handle vibrations, pressure, and other mechanical forces present in the recycling equipment. It’s essential to select a wire mesh that works harmoniously with the rest of the system to prevent bottlenecks or breakdowns.

4. How to Produce the Extruder Screen Mesh?

The extruder screen is cut from the wire mesh roll by punching with an appropriate mold. While manufacturing the extruder screens, the wire mesh roll is thoroughly checked and passed through vigilant quality control measures. The manufacturing process for an extruder screen involves several steps. The specific process can vary depending on the manufacturer and the type of screen being produced, but some of the common steps include:

4.1 Wire selection: The first step is to select the best quality woven wire mesh for the screen. The wire can be made from various materials, such as stainless steel wire, nickel wire, or copper, and comes in different gauges and diameters.

4.2 Weaving: The selected wire is then woven into a mesh screen which are available in different weave patterns and mesh count. The wire mesh selection must be of the exact specification, the mesh count, the wire diameter, and the weaving pattern should completely match the customer’s specifications.

4.3 Cutting and shaping: Apart from making a single-layer extruder screen filter, we have mastered the art of making multi-layered spot-welded filters and spin pack filters. We have a welding facility where all spot welding works are done with great care and efficiency. Once the woven mesh screen is complete, it is cut and shaped to the desired size and shape. The screen can be circular, rectangular, or any other shape depending on the specific application and requirements.

4.4 Cleaning and inspection: The extruder mesh screen is then cleaned and inspected to ensure that it is free from defects and meets the required specifications.

Cechen wire mesh has the most extensive stock of various types of molds to meet any customized requirement. It helps us to produce the desired screens faster than others, and we don’t even levy the mold cost from the clients unless it is a particular requirement.
