The advantages of the extrusion blow molding

1,The cost of the extrusion blow molding machine is cheaper than that of injection molding machine, about one third of the injection blow molding machine. 2,On blowing molding, the preform is formed under low pressure through the extrusion equipment heat, in this circumstance, the residual stress of the products is small. With its good performance […]

Single Screw & Twin Screw Extruder Difference

single screw:In single screw extruders, a screw mixer melts the entering plastic materials, pushes the material through the extruder, and forms the plastic into the desired shape. Twin screw:Twin screw extruders have two intermeshing screws and operate in the same manner as a single screw extruder. The picture below shows the barrels of the extruder […]

Overjacketing And Tubing Extrusion

Overjacketing and tubing extrusion are highly preferred processes for extruding a range of plastic materials. The overjacketing extrusion process is discussed here. In the process of wire coating, the bare wire or some bundles of jacketed wires, filaments, etc. are pulled through the die’s center, which is similar to the tubing die. The different materials […]

Extrusion Materials – Polymeric Materials

Polymeric materials are widely extruded into various products, using sophisticated extrusion machines such as extruder and others. The finished products are used for consumer as well as industrial applications. This extrusion process is an integrated one, in which extruder involves one of the components of the complete line. On the basis of the requirement of […]

Extrusion Process

Extrusion Process begins by heating the stock material (for hot or warm extrusion). It is then loaded into the container in the press. A dummy block is placed behind it where the ram then presses on the material to push it out of the die. Afterward the extrusion is stretched in order to straighten it. […]

Extrusion Reprocessing

The term¬†extrusion reprocessing refers to the minimizing of the scrap generation and recapturing of the material value in most of the operations. In almost all types of extrusion processes, it is a common practice to grind up the scrap materials by using granulator or allied suitable equipment. With the usage of this equipment, such granules […]

Basic Extruder Machine

Every extrusion company has its own variation of plastic extruder, but the basic operation of all the machines remains the same. Firstly, there is the feeder zone, which transfers the pellets or powder resin from the hopper to the barrel. The plasticizing unit consist of a feed screw, barrel and temperature controller where the resin […]
