Metal Fabrication and Heavy Structure Fabrication

1. Cutting

Our heavy steel fabrication workshop is equipped with state - of - the - art cutting equipment. First and foremost, there is a 12,000 - watt high - power fiber laser cutting machine, which can achieve high - speed and high - precision cutting with its powerful laser source. Additionally, we have multiple large - scale universal metal band sawing machines. The "universal" here means their angles can be adjusted arbitrarily, providing great flexibility for different cutting requirements. Complemented by a hydraulic press, which can apply high pressure for metal forming and processing, and an automatic punching and shearing machine that integrates punching and shearing functions for efficient material processing.

This advanced suite of equipment enables us to handle precise cutting tasks for a diverse range of materials, such as steel plates, angle irons, channel steels, and circular pipes.

2. Forming

As a professional and reliable structural steel fabrication services provider, we have a comprehensive series of metal fabrication equipment. This includes multiple CNC bending machines with different tonnages. They can handle a wide array of metal materials, spanning from stainless - steel plates, carbon - steel plates to wear - resistant plates.

We also own a CNC four - roll plate rolling machine. It can efficiently roll metal plates into seamless circular or conical shapes. This machine is applicable to produce cylindrical, arc - shaped, and conical metal components.

With our professional metal fabrication facilities, we are capable of providing a one - stop custom metal fabrication service to a large number of users.

3. Welding

We are equipped with three - axis welding robots that are capable of performing high - quality welding tasks with extremely high precision and consistency. These robots can adapt to various welding scenarios, significantly enhancing the quality and productivity of our welding operations.

In addition, our factory is equipped with orbital semi - automatic welding machines. These machines are specifically designed for welding along specific tracks, making them ideal for projects that require precise and continuous welding on cylindrical or curved surfaces.

Moreover, we have dozens of CO₂ gas shielded welding machines at our disposal.

Our welding team consists of experienced operators, each with years of practical welding experience. Their expertise enables them to execute professional welding seam construction operations with finesse, ensuring that every weld meets the highest industry standards.

Our welding workshop is equipped with a central mixed gas supply system. This system ensures a continuous and uninterrupted supply of shielding gas, which is crucial for maintaining the integrity and quality of the welds.

4. Surface Treatment

One of the key processes in metal fabrication is the surface treatment of metals, which includes shot blasting of metal structures, dust cleaning, spraying of high-quality coatings (usually divided into primer and topcoat), as well as quality monitoring of this process. For example, in order to improve the firm bonding between the paint and the metal surface, it is necessary to completely remove the rust layer, oil stains, and dust on the metal surface. Therefore, the shot blasting process needs to be utilized to increase the surface roughness of the metal.

The fully automatic overhead chain type shot blasting and rust removal system of CAFU Machinery can perform shot blasting treatment on metal components without any dead angles in a 360-degree manner. After the components come out from the shot blasting production line, high-pressure clean compressed air is required to remove the dust particles on the surface. After a comprehensive inspection of the surface of the structural components, they will enter the spray painting booth equipped with a negative pressure system for surface coating. After the coating on the metal surface is completely dry, it is also necessary to conduct inspections of the dry paint film and tests of the adhesion rate.
