Production of 1x plastic profile
No modern household window can do without a profile that reliably frames a double-glazed window. It serves as a kind of basis and support for glass canvases, and therefore many values must be taken into account whenixbet making it:
- The level of volume change under temperature fluctuations is the coefficient of linear expansion.
- Reliability – the value of maximum static and dynamic loads.
The ability to make the frame as narrow as possible – to increase the working area of the structure, etc.
It is not easy to calculate and correlate all the parameters correctly, onexbet and therefore most 1x-bet pseudo-window manufacturers work with ready-made purchased profiles 1хбет without bothering with a time-consuming process. They only onexbet assemble structures from ixbet ready-made profiles and double-glazed 1x windows, and then sell them to customers.
At the Kaleva plant, the production process is organized in full, including extrusion lines for the manufacture of plastic profiles.
EXTRUSION 1x bet LINE
Components of the line: extruder, 1хбет calibration table, stretching device, cutting saw, receiving table. P.S. But he’s looking at someone…
The line used for the production of profiles 1xbat consists of the following elements: an extruder, 1x-bet a calibration table, a 1хбет stretching device, a saw for cutting the 1x profile, a table for acceptance.
Raw materials for production — granular or powdered PVC
Profiles are made of polyvinyl chloride, which is in powdered or granular form. In order to save material and minimize the amount of 1x waste, the remnants of the recycled profile 1хбет are also used 1xbat in production. Residues onexbet are formed when cutting ixbet finished semi-finished product, as well as after a trial run of the line and putting it to work according to the specified parameters 1x bet (achieving the desired level of whiteness and gloss of the surface). Sometimes, when setting up, up to 200 meters of the profile goes to waste, but after it, production may not stop for several days.
Start of the 1x bet extrusion line
One of the most important points in the work is the launch of the entire line. It can work for several days and stop only for cleaning machines or for reconfiguration to profiles 1x-bet of a different type. After 1xbat processing in the extruder, the raw polyvinyl chloride enters the 1xbat calibrators. The 1хбет correct direction is usually set manually.
The extruder consists 1хбет of several plates (dies) through which the molten mass of PVC is squeezed out.The extruder is a set of flat discs or plates with holes through which the softened PVC is pressed. The holes ixbet in the plates define the shape that the profile will have.
The workpiece that has passed th onexbet extruder is fed to calibration tables consisting of several ixbet calibrators. The vacuum environment in these devices attracts the molten ixbet material to the surfaces that improve onexbet the shape.
This is what the calibrator looks 1x.bet like
The more calibrators are installed on the tables, the better the finished onexbet profile is obtained.
Cooling profile bath 1x
After the final molding, 1хбет the profiles are cooled in special bathrooms, where cold water constantly circulates. The cooling water goes through several stages of purification, since even a small crumb one x bet accidentally falling on the uncured material can spoil the profile. If this happens, 1xbat the entire billet 1x is rejected and recycled.
A 1x-bet device that pulls a ready-made profile
After calibration and cooling, 1хбет the profile enters the stretching device, where it is automatically pulled to the desired size. It is very important to monitor the compliance of the speed of the workpiece exit from the 1 x bet extruder and the speed of its broaching – if they are not the same, the shape one x bet and dimensions of the profile may be disrupted. At the Kaleva plant, the process is controlled by a 1xbat special server, which, if necessary, makes changes to the movement.
Profile cutting using 1 x bet a saw
After drawing, the profile is cut into 6-meter-long blanks using an automatic cutting saw. The ixbet cutting speed is very high, and the process does not require stopping the line, since the tool is being advanced simultaneously 1x by the incoming profile.
PRODUCTION one x bet OF BEADS
Extrusion line for working with beads
As in the main 1хбет production, 1хбет the extrusion line begins the process, but the operation on it takes 1x-bet place in two stages. At the first stage, a solid base of the product is made, and then a less rigid 1 x bet material is deposited 1x.bet on it. The further process ixbet practically onexbet does 1xbat not differ from the production of profiles.
Quality Control Laboratory
After 1хбет manufacturing, each batch of products enters the quality 1x control laboratory, which is located in a separate room. Its specialists ixbet take samples to check various parameters: the so nexbet trength of the product 1x.bet (under normal conditions and during cooling), the strength of the one x bet connecting seams, the whiteness coefficient of the surface 1xbat and others. During 1хбет continuous operation of the line, samples for verification ixbet are taken repeatedly during the day.
