Casting production line
The company has 5 domestically advanced melting and casting production lines, using on-line addition of aluminum-titanium-boron wire online refining, and using online degassing and multi-stage foam ceramic filter plate purification device. Compared with traditional melting and casting equipment, the advantages are as follows:
1. Gas consumption 70-80kg/t.Al
2. Burning 1.0-.5%
3. The production efficiency is doubled, and the use of forklift feeding, mechanical slag removal, etc., effectively reduce labor intensity.
4. The temperature difference in the furnace is less than or equal to ±5 °C.
5. Adopting the direct reading spectrometer introduced in the UK, strictly in accordance with AA standard, ALCOA standard, ALCAN standard or customer specified chemical composition standard, to ensure the homogenization and crystal formation of aluminum rod melting and casting products to ensure a reasonable proportion of alloy composition, raw materials The domestic and international high-quality A00 aluminum ingots are selected from the five major aluminum plants in China. At present, the casting workshop can produce various alloy grades such as 6061, 6063, 6005, 6082, 3003, etc., to meet the needs of customers' alloy types. The specifications of ingots that can be produced are Φ254, Φ150, Φ120, Φ105, Φ90 and so on.

Mold design and processing
The company has a complete line of mold manufacturing lines from mold design, mold manufacturing, mold heat treatment, etc. In order to improve the processing quality and manufacturing level of the mold, the company introduced two CNC machining centers and one slow wire, vacuum heat treatment from Taiwan. Furnace, etc. The extrusion die used by the company is designed with high quality special mold steel at home and abroad, with advanced technology, perfect production equipment and exquisite processing methods. In order to meet the multi-series requirements of customers, the computer has been realized from mold design, development to manufacturing. Management, using CAD/CAM mold development system in design, can meet the various requirements of customers with high difficulty and high precision.
In general, the mold processing flow chart is as follows:
Unloading›Roughing›Drawing›Milling›Heat treatment›Cutting wire cutting›Electrical discharge machining›Fiber work refining›Acceptance.
According to the size of the mold and the complexity of the section of the profile, it is easy to process the mold. The maximum mold diameter is 555mm. In general, the production cycle of the company's planar mold is 5 to 10 days; the split mode is 7 to 15 days.

Extrusion line
The company has 8 extrusion lines of 3600T, 1500T, 1000T, 800T, etc., equipped with a good cooling system to meet the mechanical properties of aluminum profiles under different conditions. For high quenching sensitivity or large cross-section size, the extruder cannot be realized. On-line quenching type, rod and pipe, the company is also equipped with a dedicated off-line vertical solution hardening furnace for solution quenching, and can also be used for drawing and other post-processes. At present, the product covers sections of various sizes (maximum 420mm) ) and heat treatment conditions such as T4, T5, T6, T66, etc., can meet the individual requirements of customers.
The aluminum rod heating furnace for the extruder is all equipped with a long rod heating shearing device, which significantly improves the yield. At the same time, the company is equipped with 4 aging furnaces, the longest aging of 14.5 meters long profiles, greatly enhanced processing capacity, significantly reducing profile parking time and speeding up cycle production.

Surface treatment production line
The company has 9 anodizing and coloring, can handle up to 13 meters, and 2 electrophoretic painting production lines, which can handle 13 meters of profiles.
The company has introduced one powder coating production line from Switzerland, one fluorine carbon production line in France and one wood grain production line. The powder has a short color change time, high powder recovery rate, uniform coating, no sag phenomenon, and a continuous, smooth coating film on the tip and rough surface of the workpiece. The curing oven temperature difference is less than or equal to ±2.5 °C, can handle profiles up to 13 meters, using high-quality raw materials and strict process control, so that the spray products maintain the same color, uniform film thickness and rich color, providing designers with a Broad design space.
The thermosetting resin powder used by the company is purchased from the world famous brand AKZONOBEL powder coating company. The raw materials for the production of powder are all imported from abroad, and the manufacturer provides the guarantee book" for the corresponding weathering period. The adhesion, weather resistance and peeling resistance of the aluminum powder coating layer The ability and UV resistance are strong, and the surface treatment of aluminum profiles is unmatched. "
