At the request of the customer, it is possible to produce a drawing profile from other deformable alloys.
A drawing aluminum profile is made to order with the following characteristics:
– The largest diameter of the circle is up to 200 mm, with a width of up to 240 mm.
– The weight of the linear meter is up to 9 kg.
– Drawing aluminum profile with a length of 2.0-8.0 m.
– Cutting in moderation – at the request of the customer.
First, a billet of the appropriate size is cut from the rolled steel of the corresponding grade according to the size table. Next, the workpiece is sent for processing in the forging and thermal department of the workshop. It is heated there, then forged into size according to working drawings. After forging, the workpieces are subjected to tempering to relieve internal stresses. After procurement and forging-thermal operations, forgings undergo turning, grinding, marking and drilling of technological holes, milling, deepening for marking of the product and ultrasonic inspection for internal defects and cracks. Such processing stages are carried out by all, without exception, blanks for the manufacture of all types of pressing tools.
Further processing of the matrices is somewhat different. After the above operations, the matrix blanks are subjected to hardening and grinding. After that, the blanks are fed for electroerosion treatment. After electroerosion treatment, the matrices undergo a complex of finishing operations, after which they are nitrided.
During prolonged nitriding, brittle, highly nitrogenous phases are formed in the matrix layers, caused by pressing, especially in the zone of belt calibration, causes the formation of cracks and chips reinforced by diffusion.
Therefore, the effectiveness of nitriding reinforcement significantly depends on the composition of the steel and the mode of chemical-thermal treatment, which determine the phase composition, the structure of the diffusion layer, the strength of its adhesion to the metal base and resistance to variable force and thermal influences.
Scope of application:
You can order a drawing aluminum profile for: ventilated facades, heating radiators, sliding furniture, translucent structures, partitions in offices, LED devices, machine tools, heat exchange systems, electronics, conveyors, exhibition and trade equipment, tent complexes, refrigeration equipment, transport engineering, ventilation systems, furniture manufacturing for medicine and industry, interior and construction work, outdoor advertising and much more. You can also order an aluminum profile from us according to the drawing.
The manufacturing process uses an adjustment section and a matrix tool from leading manufacturers and is adjusted by highly qualified specialists. Etching baths clean the matrices from aluminum. There is also sandblasting, catalytic gas nitriding – all this will increase the thickness of the products from each die and the time of its operation.
Automated lines based on hydraulic presses with a force of 100-2800 tons are used in the press section. An optical pyrometer is used at the output for comprehensive temperature control and to obtain stable properties. All measurement data is stored in the computer. Shot blasting is carried out automatically on the appropriate equipment with stainless shot. As a result, the products have a matte surface without extrusion strips.
At the anodizing site, the plant has the ability to anodize objects up to 7.5 m long.
The area of the wrapper is decorated with thin PVC.
At the last stage, the production of aluminum profile according to the drawing ends with packaging for safety during transportation. Pallet packaging makes it possible to simplify unloading, warehousing, loading of products.
Our products are designed for:
– Enterprises producing and selling aluminum profiles, having their own press production;
– Enterprises that sell aluminum profiles, but do not have their own presses, but order on the side through "outsourcing".
Matrix tooling in our company is changed strictly after 10 tons of extrusion of aluminum furniture profiles, and after extrusion of aluminum edges, after every fourth ton.
Aluminum profiles are produced using a flat, disc-shaped matrix. The dies (extrusion dies) are made of tool steel with a hole depending on the size and shape of the intended cross-section of the final aluminum profile.
The matrix kit is a prefabricated tool consisting of several metal discs made of high–quality steel, in each of which various structural elements (holes, grooves, dividers) are made to give the pressed profile the necessary shape. Assembled presses the quality of manufacturing of the matrix kit depends on the compliance of the resulting profile with the requirements of the drawing, so all our matrices are made only by world leaders in these areas.
There are two main groups of matrices that produce aluminum profiles.
– Hollow aluminum profiles – a profile whose cross–section includes one or more internal hollow spaces.
– Solid profile - a profile in the cross-section of which there is no internal hollow space.
The design is carried out by an experienced specialist with a higher technical education. Specialized software is used, where the simulation of the pressing process is necessarily carried out.
All this allows you to:
– form the correct pressing parameters (the required temperature of the workpiece, pressing speed, etc.);
– to prevent the uneven flow of aluminum through the belts and channels of the matrix;
– reduce to a minimum the necessary adjustment of the matrix before testing (crimping);
– increase its service life.
The customer is also provided with recommendations on improving the cross-section design, reducing asymmetry, using technical radii of rounding, minimizing the ratio of thick and thin walls, etc.
The cost of the matrix includes: design, production, adjustment, crimping (with the provision of a sample) and warranty service.
The Aluminante plant manufactures, according to the customer's drawings, a tool for the production of aluminum profiles, fully accompanying the design from the idea to the finished product. We will bring to life any fantasies about the aluminum profile.
