Melt Pump and its application in plastic industry
One of the main components in the production of plastic parts is the structural density of the polymer and the intertwining of the polymer chains. One of the most effective solutions for this purpose is to create high pressure in the polymer forming process. The presence of pressure entangles the polymer chains and no structural vacuum remains in the product.
This issue is very important in the production of polymer sheets and sheets from PVC sheets to geomembrane sheets and fabrics of Melt Blown, because molds are used to produce sheets that have to take the polymer fluid from the extruder and sometimes up to 10 M to spread it to the sides and a sheet 10 Meters to deliver. This requires a high pressure, which can not be produced by the extruder. For this purpose, a part called the Meit pump is used, which in addition to providing the required pressure behind the mold, evens the fluid flow..
In the absence of melt pump in the production lines of polymer sheets, the quality of the product changes in width, so that in the middle of the product, the production density and production speed are high, but on both sides, both quality and speed will be very low.
With Melt pump, both the velocity and flow rate of the material will be uniform throughout the width of the mold, as well as its quality.
It is necessary to explain and note that among the manufacturers of the device in Iran, only 2 or 3 units have a license and exploitation license for industrial and mining structures. Behsaz Polymer Industrial Group has been operating under the license of the Industrial Organization since 2000.
And also, unfortunately, most advertisers on the Internet are intermediaries as manufacturers of disposable tableware and do not have any license from the Department of Industry and even choose the name of the company or brand to introduce their product is not registered in any office or organization.
