Problems solved by technology

[0003] However, PFA plastics are different from PP and PVC sheets. The processing temperature of PFA plastics is high and can be formed at high temperatures. When ordinary PP plastic injection molding machines process PFA plastics, the surface of the finished product is uneven and uneven, and the existing PFA injection molding machines, The structure is complicated and the price is expensive. For this reason, the invention provides a PFA plastic product molding extruder, which has a compact structure design and good injection molding quality. The processed product has no gate plastic traces in the mold cavity, and the molding extrusion The machine adopts double barrel feeding, high processing efficiency

Abstract

The invention discloses a molding extruder of PFA plastic products. The molding extruder comprises two support legs, wherein a support stand column is connected to each support leg; the top end of each of the two support stand columns is connected to a horizontal beam structure; an extruder body is arranged on a horizontal beam; a hydraulic cylinder is arranged at the upper end of the extruder body; the extruder body adopts a vertical structure; a housing is made of a double-layered material; a material heating chamber is formed in the extruder body; left and right symmetric material drums are connected to the housing of the extruder. The molding extruder of PFA plastic products is compact in structure design and high in processing efficiency; the surfaces of the processed fluoroplastic finished products are uniform and are free of folds.

Description

technical field [0001] The invention relates to the field of fluoroplastic product processing, in particular to a PFA plastic product molding extruder. Background technique [0002] Fluoroplastics are composed of carbon atoms and fluorine atoms. They have stable chemical properties and small friction coefficients. They are widely used in military and high-end products. They are not corroded by acids, alkalis, and solvents. Among the fluoroplastics family, the common one is poly Tetrafluoroethylene and PFA, among them, PFA is a copolymer of a small amount of perfluoropropyl perfluorovinyl ether and polytetrafluoroethylene, and its performance has no change compared with polytetrafluoroethylene. PFA is often used to make corrosion-resistant parts and reduce friction. For wear-resistant parts, seals, insulating parts and medical equipment parts, PFA processing is different from other fluoroplastics. Most other fluoroplastic products are pre-shaped, and then sintered in a sinter...
