Steel Casting

In the steel casting process, we use advanced three-phase electric grid to control the pouring temperature and cooling arc furnace melting technology and alkaline phenolic resin sand molding technology. Through strict process and state-of-art MAGMA casting simulation, we can produce high-strength, wear-resistant and high-quality steel castings, and control the composition of steel castings through spectrometers and crystal phase analyzers imported from Germany.

Sheet Welding

First of all, laser cutting is used to ensure the accuracy of sheet cutting. Secondly, the sheet welding process combines automated welding equipment and experienced welders to ensure the strength and beauty of each weld. Strictly control the temperature and humidity of welding materials, and strictly control the current and speed during welding.

Machining

We have world-class advanced German CNC machine tools and high-precision processing equipment, which can perform precision machining of complex parts. By adopting efficient cutting technology and fine processing technology, we ensure that the dimensional accuracy and surface quality of each part meet the strict requirements of customers.

Heat treatment

Our heat treatment process changes the internal structure of the metal and improves its hardness and toughness by precisely controlling the heating and cooling rates. We have advanced heat treatment equipment and a complete quality control system to fully release stress to ensure excellent mechanical properties and long service life.

Inspection

After each process, we conduct strict quality inspection. Using advanced testing instruments and scientific testing methods PT, UT, MT, we conduct comprehensive inspections on the product's size, shape, performance and other indicators to ensure that the product quality meets or even exceeds customer expectations.

Assembly

Our assembly process is strictly carried out in accordance with standardized procedures to ensure the correct installation and tight fit of each part. Through multiple trial installations and adjustments, we ensure the overall performance and work efficiency of the product and maximize the reliability and stability of the product.

Sandblasting

In the sandblasting process, we use efficient sandblasting equipment to remove the oxide scale and impurities on the surface of the parts, increase the surface roughness, and lay a solid foundation for the subsequent painting process.

Painting

The static pressure adsorption paint room ensures that the product has good anti-corrosion performance and beautiful appearance through multi-layer spraying and fine surface treatment.

Packaging

In the packaging link, we use professional packaging materials and technologies to ensure the safety and integrity of the product during transportation. Through strict packaging inspection and optimized packaging design, we effectively reduce the risk of transportation damage and ensure that the products are delivered to customers intact.
