Basic Information

The unevenness of the aluminum profile in the longitudinal direction is called bending; the uniform bending along the longitudinal direction is called uniform bending; the sudden bending in the aluminum profile is called hard bending; the bending along the width direction (lateral) is called knife bending; the main reason is After the working belt of the mold design or the profile flows out of the die hole, the front end is suddenly subjected to resistance somewhere and bends immediately; or after the aluminum profile flows out of the die hole, the cooling rate is large, and the shrinkage is unbalanced everywhere, causing bending;
Elimination method:
1) Repair the mold working belt to ensure that the aluminum profiles flow evenly;
2) Install a suitable guide path, and keep it smooth from the discharge table to the sliding table, and there must be no obstacles that prevent the profile from advancing;
3) Appropriately increase the elongation rate and straighten the aluminum profile;
4) Properly control the extrusion speed, the cooling air should be uniform, and avoid blowing the cooling profile from one side;

Aluminum tubes can have one or more closed through holes, uniform wall thickness and cross-section, and are delivered in straight or coiled form. Widely used in automobiles, ships, aerospace, aviation, electrical appliances, agriculture, electromechanical, household and other industries.

Company Profile

Jiangyin Longkang Metal Products Co., Ltd. is located in Zhouzhuang Town, Jiangyin City - the largest aluminum extrusion profile production base. Covering an area of more than 35,000 square meters with more than 350 employees. We focus on metal customization, special-shaped aluminum profiles, aluminum profiles, aluminum tubes, rail transit series, doors and windows aluminum profiles, heat sinks, CNC processed aluminum profiles, interior decoration series, bending series, etc. We also have precision anodizing and various surface treatments, such as PVC film, wood grain, electrophoresis, powder coating, anodizing, etc. After more than 20 years of development, The company has become a modern aluminum production enterprise with perfect quality management system.

The company has the ability to develop and design molds independently, we can produce any extruded aluminum profiles according to your mechanical drawing or sample. Longkang has 10 extrusion production lines (600-3500 tons), one automatic oxidation electrophoresis production line, vertical and horizontal spraying production line per each, and a variety of advanced supporting production, processing and testing equipments. There are also CNT digital control drilling and milling machine(CNC), double head saw, hydraulic saw and punching machine in our processing workshop. The complete technological process can benefit to reduce the production turnover times for semi-finished products, to avoid the damage during transportation, improve the production efficiency, reduce the cost of production,and to ensure the quality and delivery time.

Efficiently treating our customers as partners with sincerity, specialization and satisfaction is our managerial principle. Attributed to the backup of a dedicated technical team, filled with wide and profound knowledge and practice in aluminum profile and world trade for 20 years, the company owns rich experience in product quality control and profile physical properties such as Hardness, Stretchability, Flatness, Straightness, and Tolerance etc. In line with the principle of sharing the preferential cost and joint development, the company has formed an interest community for years with its customers at home and abroad. Sincerely to build up a pleasant mutual trust, cooperative, win-win and value-added sustainable partnership is what we are achieving to grow together with you !
