Process flow @ KMC, Manufacturer of high-quality aluminium extrusions
Furnace
Furnace is where aluminum ingots or aluminum materials are melted down and molded into finished or semi-finished products by molten casting as shown in the Diagram
Billet cutting
A billet is a section of metal used for rolling into bars, rods and sections. It can be produced with ingots or directly by continuous casting. Billets are used as raw materials or extrusion processing operations.
Continuous Billet Heating
Metal billets are heated prior to forming operations (extrusion, for example). Heating the metal softens it and makes it malleable. If the metal is heated too much, then excess time and energy is used and damage can occur as extra heat is generated during the deformation process. If the billet is not heated enough, then the cool billet will be too hard to form or it may not achieve the desired hardness properties upon cooling. If the billet is too hard, it may not flow to the required shape and it may cause excessive die wear.
Die Heating Oven
Properly used, the die oven should heat the tooling to the desired temperature without regard to where each tool is placed in the oven. The tool’s time in the heater should be carefully managed: if not heated long enough the die may break; if heated too long the hardness will be lost (also resulting in breakage), and oxidation or pitting of the surfaces may occur.
Extrusion Press
Direct extrusion, is the most common extrusion process. It works by placing the billet in a heavy walled container. The billet is pushed through the die by a ram or screw. There is a reusable dummy block between the ram and the billet to keep them separated. Because of this the greatest force required is at the beginning of process and slowly decreases as the billet is used up. At the end of the billet the force greatly increases because the billet is thin and the material must flow radially to exit the die. The end of the billet(called the butt end) is not used for this reason.
Transfer Table Conveyer
A conveyor system is a common piece of mechanical handling equipment that moves materials. Conveyors are able to safely transport materials from one level to another, which when done by human labor would. It is important to note that either air compressors, vacuums, or blowers can be used to generate the air flow.
Stretching & Straightening
For the straightening of solid bars, square and rectangular tubes as well as hollow profiles, our profile straightening machines are designed especially for your application to reach an optimum straightening quality. The number of straightening rolls, as well as the number of straightening planes are adapted to the profiles to be processed. For square and rectangular tubes, straightening machines with adjustable straightening rolls’ pitches are used.
Cutting
It has a feature of easy operation, reliable performance, advanced technique and convenient maintenance.
The profile cutting size adopts the digital display technique to ensure high efficiency and accuracy.
Imported carbide saw blade gives accurate processing and high efficiency.
Two cutting heads can work together or single, when together work, one time can cut off the required length and angle.
It’s a high efficiency cutting machine for aluminium window and door profiles, industrial aluminum profiles and curtain wall aluminium profiles, aluminum ladder profiles etc..
Ageing
The aluminum profile should be carried out aging treatment after extrusion, the purpose is to improve the intensity of the aluminum alloy shape and benefit to operation, storage and transportation for the after extrusion procedures, and also for normal usage of the clients. Technical Process:190 ℃ ~ 195 ℃ for keep warm about 3.5 hours, and then adopt the forced-air-cooling process.
