At Qiusuo, precision cutting is an integral part of our wedge wire production process. We utilize advanced cutting techniques to transform half finished wedge wires into finely crafted wedge wire screens, filters, and related components tailored to your unique specifications.

Laser Cutting

Laser cutting is a precise and versatile manufacturing process that is used in wedge wire production. It involves using a high-powered laser beam to cut through materials with a high degree of accuracy and minimal heat-affected zones. During wedge wire production, laser cutting can be applied to shape, size, or create specific patterns in wedge wire panels or tubes.

A laser cutting machine is cutting the wedge wire panel.

Shearing refers to the process of cutting or shearing wedge wire screens, panels, or tubes to specific lengths or dimensions in wedge wire production. The goal of shearing in wedge wire production is to create components with precise dimensions and clean, straight edges.

It is commonly used to cut the wedge wire cylinders or tubes into panels or cut the wedge wire panels and tubes into specific dimensions.

Laser Cutting VS Shearing
- Laser Cutting Shearing
Cutting Method Mechanical cutting thermal cutting
Precision Good precision and accuracy for straight-line cuts Exceptional precision and can create complex, detailed designs
Speed and Efficiency Relatively fast for wedge wire with uniform shapes Fast and efficient in cutting complex shapes and patterns
Edge Quality Clean, straight edges with minimal burrs Excellent and no need for secondary finishing
Complex Shapes Suit for straight cuts and basic shapes Excels at cutting complex shapes, fine details, and intricate patterns

The laser cutting machine can be used to customize special shaped wedge wire panels, cylinders and other wedge wire products. It can also be used for wedge wire tube cutting into specific dimensions.

Roll Bending

Some wedge wire cylinders, baskets or customized shaped wedge wire products are often made from wedge wire panels. To make a wedge wire basket from wedge wire panels, the panels are manipulated and assembled to form the desired basket shape. And the first step is roll bending.

Roll bending, also known as plate rolling or section bending, is a metal forming process used to bend flat or curved sections of wedge wire panels into various shapes, including cylinders, cones, and curves. In wedge wire production, roll bending is often used to shape flat wedge wire panels into cylindrical or conical forms.

  • Versatility. create a wide range of shapes, including cylinders, cones, and curves
  • Consistency. provides consistent results across multiple pieces or batches, ensuring uniformity in the curvature of the components
  • Cost-Effective. cost-effective and particularly for large-scale production
  • Precision. Roll bending machines allow for precise control over the radius of the curved shape, ensuring that the final product meets tight dimensional tolerances.

Roll bending machine is the necessary process in wedge wire panel and sieve bends productions. Sometimes, it can be used to prepare wedge wire panel material for wedge wire cylinders or baskets.

TIG welding

TIG welding (Tungsten Inert Gas welding) is a manual welding process. In TIG welding, an operator manually controls the welding torch, electrode, and filler material (if necessary) to create the weld joint, making it well-suited for applications where requires high precision and weld quality, such as welding filter baskets, flanges, or frames. Our skilled workers have years of experience to ensure precise control over the welding process and clean, precise connections in critical components.

Wedge wire cylinder rounding is necessary when the cylinder roundness can not meet dimensional specifications. The cylinder is fed between the rollers, which are adjusted to apply pressure to the non-round areas. The cylinder is incrementally rolled to achieve the desired roundness.

A rolling equipment is rolling wedge wire screen cylinder.
  • Guarantee the dimensional accuracy and operation efficiency of wedge wire cylinders.
  • It can ensure the maintaining consistency, improve cleanliness and make it ease of cleaning.

Rolling process is necessary for wedge wire cylinder, wedge wire basket and rotary drum screens production.

The drawing of wedge wire surface treatment.
Surface treatment
Surface treatment

In wedge wire production, we adopt pickling and electroplating surface treatment method. The whole process are typically performed in a controlled environment to ensure consistent result and compliance with industry standard. These finishes contribute to the overall quality and performance of the wedge wire product, ensuring it meets the required standards for corrosion resistance, cleanliness, and aesthetics.


Pickling is a chemical process used to remove surface impurities, scales, oxides, and contaminants from the stainless steel surface. The primary goal is to prepare the material for subsequent treatments and improve its corrosion resistance.

Immersing the stainless steel wedge wire product in a chemical bath typically composed of an acid solution, such as nitric or hydrofluoric acid. The acid reacts with the impurities on the surface, dissolving them and leaving behind a clean, passive surface.

  • Removal of scale, rust, and impurities.
  • Create a clean and uniform surface.
  • Enhanced corrosion resistance by promoting the formation of a passive oxide layer.
  • Improved adhesion of subsequent coatings or treatments.

Electropolishing is an electrochemical process used to further improve the surface finish and corrosion resistance of stainless steel wedge wire products. It removes a precise and controlled layer of material from the surface.

During electropolishing, the wedge wire product is submerged in an electrolyte bath, and an electrical current is applied. This causes the dissolution of surface irregularities and the removal of a thin layer of material. The process is highly controllable, resulting in a smooth and bright finish.

  • Create a highly reflective and ultra-smooth surface finish.
  • Remove microscopic surface defects.
  • Enhance corrosion resistance performance by promoting the formation of a passive oxide layer.
  • Improve cleanability and resistance to contamination.

Surface treatment is the necessary for almost all wedge wire products to provide extended service life in complex working conditions.
