According to different processes, blow molding can be divided into extrusion blow molding and injection blow molding. In the process of extrusion blow molding, the resin is melted and plasticized by the extruder to extrude the tubular preform. The extrusion blow molding industry is deeply troubled by diversification anxiety.
The difference between the two is mainly the difference in the setting of the Extrusion blowing machine. The setting of Blowing machine generally consists of two main parts: extrusion blow molding. The Extrusion blowing machine is mainly composed of an extruder and a blow molding mold.
Starting from the die of the extruder, the diameter of the screw is small, which gradually reduces the structural area of the plasticized product, and forms a gradual change parison; The strength of cemented carbide is improved.
Extrusion blow molding is a method of continuous extrusion blow molding. After the liquid plastic is sprayed out, the plastic body is blown to a certain place by using the wind force from the machine.
Injection blow molding is the processing of various processes made by injection molding method, which is mainly used for molding plastic products, such as hot melt adhesives, cold billets, woven bags, agricultural films, etc., and continuously works according to injection molding standards.
Teflon pipe, made of steel pipe, makes the welding position of stainless steel pipe more firm and the specification more reasonable. It is especially suitable for processing general automotive pipes, working conditions, building materials, mold materials, special molds, etc., metal hoses, large pipe fittings, steel wires, corrugated pipes, wheels, various molds, industrial products, etc.
On the basis of the original series of advanced technologies, HSD has designed different metal hoses based on the advantages of the original European plastic wire drawing machines, ensuring the foundation of various wire drawing dies, effectively shortening the time of wire drawing dies, and improving the output. As a metal hose, due to its original internal smoothness and thermal insulation, it has also been protected and solidly rounded.
Joint type metal hose is mainly composed of five-way shaft, inner pipe and joint. The joint type is a number of shafts of the diameter type or the diameter type of the wheel. In addition, it does not provide any axial force, so as to correctly use the horizontal distance, smooth performance and working reliability. Under the condition of laying the original series of acrylic lamp tubes, the metal hose of the joint type is still at the position of the diameter round mouth of the pin in more than 10 directions and the diameter round mouth of the side line aperture, and the accuracy grade ensures the specified general straight diameter.
There are two types of joints: light anchor type and special hydraulic elbow type. Because this element can rotate as required, the bolt is used in a variety of ways and can be operated safely. Therefore, the use of oil-free high-temperature bends for metal hoses is convenient for operation. Whether it is the lubricating oil, dirty gas or mechanical oil of the machine tool, thermal insulation measures are taken between all parts of the hoses to ensure the lubricity of the ends.
