Polymer Productction

Thermosets. Facilities that produce/formulate thermoset polymers typically describe the initial reaction phase as “condensation” polymerization. During the reaction, a condensate is formed when unreacted and partially reacted monomers and additives, in combination with water molecules released in the reaction, vaporize, cool, and then collect in a condenser or series of condensers. This condensate, if not […]

Rotational moulding,Powder injection moulding and thixomoulding

Rotational moulding In rotationalmoulding,a chargeof plastic powderis placed in one half of a metal mould.The mouldhalves are thenclamped together and heated while the mould rotates biaxially. The powder particles melt and coalesce to form a homogeneous layer on the surface of the mould. The mould is then cooled and the polymer layer densiŽ es and […]

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 […]

Polymer Screw Extrusion

Polymer Screw Extrusion

Most polymeric materials are extruded at least twice in their lifetime, Ž rst through a pelletising die after the reactor and then for Ž nal shaping.In simplest terms, screw extruders are polymer pumps with the capacity to melt the material which they are fed. Screw extruders comprise one or two Archimedean screws rotating in a […]

Ram Extrusion Process

Multi-hole Ram Extrusion Process

Multi-hole ram extrusion is the process in which the raw material is pushed through a die having more than one hole. This process is highly productive for producing parts of smaller length and cross-section. For the given billet and final product size, the requirement of the ram force is lesser in the multi-hole extrusion than […]

plastic extrusion process

Types of Plastic Extrusion Process

The plastic extrusion process is broadly classified into seven different types depending upon the specific applications. (A) SHEET/FILM EXTRUSION In this extrusion process, the molten plastic material is extruded through a flat die. The cooling rolls are used to determine the thickness of sheet/film and its surface texture. The thickness of sheet can be obtained […]
