The Key Principles of Extrusion Part 2
The following are important principles to keep in mind regarding extrusion. They should help save money, yield higher quality products, and use equipment more efficiently. 4. The feed acts as the coolant.Extrusion is a transfer of energy from the motor—and sometimes the heaters—to the cool plasti...Read more -
Development of key technology of coaxial twin screw extruder
The torque transfer mode between screw and mandrel is the key to realize the deep screw groove. The torque transfer between the screw element and the mandrel was initially connected by flat keys, which not only limited the deepening of the screw groove and increased the free volume of the screw, ...Read more -
Tube Plastic Extrusion Machine Process
Plastic extrusion of tube, hose and pipe is a steady-state process for converting a thermoplastic raw material to a finished or near-finished annular product. The raw material is usually in the form of plastic pellets or powder. The conversion takes place by forming a homogeneous molten mass in t...Read more -

Die Extrusion – Polymer Extrusion Process
Once a polymer has been melted, mixed and pressurised in an extruder, it is pumped through an extrusion die for continuous forming (after cooling and solidification) into a final product. The most common die types are flat, annular and prole. Products made by extrusion include pipe, tubing, coat...Read more -
The advantages of the extrusion blow molding
Molding Machine are those which are used to make shapes out of materials such as plastic, rubber and metal. There are a lot of different techniques for molding materials. The Stretch Blow Molding Machine techniques used is thermoses and thermoplastics and these change the nature of the plastic th...Read more
