Filter Press Production Process

The production of filter presses is a process involving multiple steps and precision engineering, which mainly includes the key stages of cutting and processing parts, sandblasting, assembly, debugging, and painting. The production process of filter presses will be introduced in detail below.

Cutting and Welding

The key components of the filter press such as Beam, Head and tail plate are usually made of high carbon hard steel, Q235 steel or Mn steel, etc. Each component needs to be formed through cutting, welding, and other manufacturing processes. This process is to cut and weld the filter press beam.

CNC Processing

In addition to key components, the filter press also has many other small parts. Each component must be processed carefully to ensure the quality of the filter press.



Sandblasting of filter presses is an important production and manufacturing link, mainly used to improve the surface quality of filter press components. Sandblasting usually occurs before assembly. The equipment in the picture is mainly used to sandblast the beams of the filter press to remove surface rust.


Sandblasting is a critical step in ensuring that the filter press maintains high performance and durability over the long term. At the same time, sandblasting can also increase the roughness of the metal surface, which helps improve the adhesion of coatings or protective materials. This equipment is mainly used for sandblasting the head and tail plates of filter presses.



After all parts are produced, the assembly phase begins. This involves assembling components such as filter plates, brackets, and operating systems (such as hydraulic systems, control panel) into a complete filter press. During the assembly process, workers will assemble in strict accordance with the requirements to ensure the correct docking of various components, thereby ensuring the stability and effectiveness of the machine.


After assembly, the filter press undergoes rigorous testing to ensure it meets design standards and operating efficiency. Before handing over the filter press to the customer, workers will perform on-site installation and debugging to ensure that the filter press can operate normally in the actual working environment.

spray paint


The painting process of a filter press is an important manufacturing step that not only enhances the appearance of the equipment but also provides an additional layer of protection to it, enhancing its corrosion resistance and durability. Applying a primer before painting will help improve the adhesion of the topcoat while providing a layer of rust protection to the metal surface.

After painting, the filter press production process is finished and will be ready for delivery.
