01

Cutting

According to the specifications outlined in the metal filter element drawings, the stainless steel mesh shall be cut to the required dimensions and contour using either a cutting machine or shears. Particular attention must be paid during this fabrication process to ensure the dimensional accuracy and surface finish of the metal filter element.

02

Reinforcement/Framing

The edges of the pre-cut woven mesh are reinforced to enhance structural rigidity and prevent deformation. Following the reinforcement/framing process, the service life of the woven mesh is significantly prolonged, while facilitating ease of cleaning and maintenance.

03

Welding

The cut/pleated stainless steel filter screen is welded into a complete metal filter element structure using the argon arc welding process. This process must ensure the sealing and structural stability of the metal filter element.

04

Pleated

The cut stainless steel filter mesh is processed by a wave-forming machine to form a honeycomb structure. This process is beneficial for increasing the filtration area of the metal filter element and enhancing the filtration efficiency.

05

Sintering

The sintering process for stainless steel filters and woven mesh involves thermally bonding all contact points of the woven mesh through high-temperature heating, thereby yielding a mesh structure with superior strength. This advanced manufacturing technique significantly enhances the performance characteristics of the mesh structure. Stainless steel filters and woven meshes subjected to the sintering process exhibit improved functional properties.

06

Forming

The process of shaping woven mesh into specific geometries, dimensions, and functionalities through techniques such as bending, stamping, welding, and other fabrication procedures. Common equipment utilized includes bending machines, stamping presses, welding machines, and winding machines, all of which contribute to ensuring manufacturing precision and enhancing production efficiency. The specific forming process employed varies depending on the application field.

07

Stamping

This process is mainly used to manufacture the end caps (used to seal the body of the metal filter cartridge), inner and outer mesh screens, and support framework (used to support and protect the internal filter media of the metal filter cartridge). It ensures the structural integrity and sealing, performance of the metal filter cartridge, and also guides the fluid distribution, reducing the load on the filter media.

08

Molding

Place the cut/pleated metal filter element on the pre-made metal mold to form the structure of the metal filter element. This process must ensure that the specifications of the metal filter element meet the requirements.

09

Bubble Point Test

Place the formed metal filter element (with a filtration accuracy of <50μm) into the equipment that holds 100% ethyl acetate. Apply pressure to test the sealing performance of the weld seam and weld of the metal filter element. This process ensures the sealing performance of the metal filter.
