Introduction of new FRP tensile extrusion process equipment and mold

New type of glass steel extrusion process equipment: (1) preheating process and equipment using radio frequency (RF) transmitter to preheating the reinforced material, which is a leap in the development of extrusion process. This change uses the combination of RF energy preheating and heat conduction of metal mold, which shortens the curing time of glue liquid and greatly improves the pull and squeeze speed.(FRP centrifugal fan) RF transmitter between the dip section and the mold section, wet fiber bundle into the mold, through the transmitter, and under the action of RF produce instantaneous molecular friction heat, reduce glue viscosity, enhance infiltration, and provide the energy needed for glue reaction, in this case, even shorten the length of the mold, glue can also gel, curing, reduce the time of material through the mold, reduce the traction tension. This great invention has significantly increased the speed of pulling and squeezing, especially in the production of large products.(FRP high pressure fan) (2) winding and pulling and weaving In order to improve the circular performance of pulling products, the winding and weaving technology elements are introduced in the traditional process, forming the drawing process and weaving and squeezing process, making the performance of pulling products get a breakthrough, the comprehensive performance is more superior.(3) extrusion and injection coating process some special requirements of extrusion products, the surface should be coated with a coating, can set a small injection molding machine, plasticizing plastic liquid bloom in a groove, from the mold pull extrusion profile immediately through plastic tank, so on the profile surface coated with a coating, appearance, performance, corrosion resistance of higher requirements.(What is FRP) (4) The principle of curve pulling and squeezing equipment is to artificially control the curing and post-curing process of pulling and squeezing products, so that the products can achieve the designed curve shape. Thus, it breaks through the traditional thinking mode of pulling can only make constant section and linear products, which can meet the needs of variable section product research and development.
In the process of drawing and extrusion molding of FRP profiles, the mold is the meeting point of various process parameters, which is one of the cores of drawing and extrusion process. Compared with plastic extrusion molding, pull extrusion molding has similarities, but the former is only a physical change process, the latter is also accompanied by dynamic chemical reaction. In contrast, the working condition of the mold is much more complicated than the former, so the design and manufacture of the mold is of great significance. It is not only related to the success or failure of the extrusion process, determines the quality and output of the products, but also affects the service life of the mold.(FRP flame retardant fan)
From the process point of view, the extrusion mold is generally composed of two parts: preformed mold and molding mold.(1) preformed mold in extrusion molding process, reinforced material imbedded resin (or soaked at the same time), before entering the molding mold, must go through a group of guide components of preformed mold, the role of the preformed mold is to make the soaked enhancement material further remove excess resin, eliminate bubbles, gradually form the approximate molding mold cavity shape and size, and then into the mold. Through premolding, the reinforced material gradually reaches the required shape, and make the distribution of the reinforced material in line with the design requirements.(FRP explosion-proof fan) (2) The ratio of the cross section area to the cross section area of the product should generally be greater than 10
