Introduction of processing flow:
⑴ incoming inspection. Check profile section size, profile straightness, blank length, surface quality as required, paying special attention to surface defects.
⑵ milling processing. For the reverse T-shaped frame, the section of the profile needs to be milled before bending. In order to ensure that the size after the bending meets the requirements, we perform milling on the gantry milling machine, and the processing size reaches the nominal value +2mm.
(3) Pre-stretching and bending. On the stretch bending machine, the blank is pre-stretched by controlling the stretch-bending parameters (stretch-bending force, stretch-bending angle, etc.) by using the stretch-bending die and the stretch-bending chuck to meet the pre-forming requirements.
⑷ repair. Check the flatness and angle of the two surfaces to ensure that these values ​​meet the requirements. For the R value, you can use a three-roll roll bender to assist in trimming, and trim it to our predetermined shape.
⑸ Inspection after pre-tensioning and bending. Check that the flatness, angle, and section width of the two surfaces meet the requirements, and the value of R1000mm reaches our predetermined shape.
⑹Transportation and preservation after quenching. In order to ensure the new quenched state of the aluminum alloy material, it is necessary to store the parts at a temperature lower than -10 ℃ before forming after quenching. The temperature of the car should be lower than -10°C.
⑺ Make up the bend. On the stretch-bending machine, the semi-finished products are re-bent by controlling the parameters of the stretch-bending (pull-bending force, stretch-bending angle, etc.) by using the stretch-bending die and the stretch-bending chuck to meet the final requirements; According to the specific conditions of different parts, the side pulling and trimming can be selectively carried out to achieve the ideal shape and size.
⑻ repair. On the calibration platform, use auxiliary tools such as hammer for trimming, and when necessary, use the calibration inspection die for knocking trim.
⑼ Inspection. Use the inspection die to cooperate with calipers and feeler gauges for inspection to ensure compliance with customer technical requirements and drawing requirements.
⑽ fitter. Use polishing tools such as scouring pads to decorate and clean the surface, and mark parts and test pieces to ensure traceability.

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.

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!

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.
