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 […]

Ram Extrusion Process

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 […]

Types of Plastic Extruders

Plastic extruders are used to create a wide range of items, including plastic tubing, trims, seals, plastic sheets and rods. Extruder is the machine for producing more or less continuous lengths of plastic sections out of a selected type of plastic resin. There are a number of extrusion techniques available such as co-extrusion, offset extrusion, […]

Single Screw Extruder

Single screw extrusion is one of the core operations in polymer processing and is also a key component in many other processing operations. The foremost goal of a single screw extrusion process is to build pressure in a polymer melt so that it can be extruded through a die or injected into a mold. Most […]

Twin screw extrusion technology

How does extrusion work? Extrusion processing aims to physico-chemically transform continuously viscous polymeric media and produce high quality structured products thanks to the accurate control of processing conditions. Twin screw extruders consist of two intermeshing, co-rotating screws mounted on splined shafts in a closed barrel. Due to a wide range of screw and barrel designs, […]

Injection Moulding Process – Injection Moulding Machines

Injection moulding is a two step cyclical process: (a) melt generation by a rotating screw, and (b) Žfilling of the mouldwith molten polymer by the forward ramming of the screw (called a reciprocating screw), followed by a very short packing stage necessary to pack more polymer in the mould to offset the shrinkage after cooling […]
