Plastic Manufacturers South Africa
Plastics conversion companies in South Africa, including plastic injection moulding companies, plastic blow mou lding companies, plastics extrusion companies and plastic rotational moulding companies in South Africa.
Plastic Injection Moulding Companies
Plastic injection moulding is a manufacturing
process for making parts from thermoplastic and thermosetting plastic
materials using plastic injection moulding machines. Molten plastic is injected at high pressure into
a mould , which is the inverse of the
product's shape. Injection moulding is widely used for manufacturing
a variety of plastic products and parts more on the injection moulding process
Blow Moulding Companies
Plastic blow moulding is a manufacturing process by which hollow plastic products
such as bottles are formed. In general, there are three main types of
blow molding: extrusion blow moulding, injection blow moulding, and stretch
blow moulding. In extrusion blow moulding , plastic is melted and extruded into a hollow tube.

Extrusion Companies
Plastic extrusion of pipe, rod and tube , profile extrusion, sheet extrusion,
film extrusion. In the extrusion of plastics, raw thermoplastic
material in the form of small beads is gravity fed from a top mounted
hopper into the barrel of the extruder. The rotating screw forces the plastic pellets forward into the barrel which is heated to the desired melt temperature

Rotational Moulding Companies
The rotational molding process is a high-temperature, low-pressure plastic-forming
process that uses heat and biaxial rotation (i.e. rotation on two axes)
to produce hollow, one-piece parts. The rotomoulding process does have
distinct advantages. Manufacturing large, hollow parts such as oil tanks
is much easier by rotational moulding than any other method.
Engineering Plastics Manufacturers
Manufacturers of products using for engineering plastics. For example ABS is used to manufacture car bumpers, dashboard trim and Lego bricks, polycarbonate is used in motorcycle helmets and polyamides (nylons) are used for skis and ski boots. Typically, an engineering plastic is chosen for its range of enhanced physical properties
Perspex Fabrication
Manufacturers of perspex products such as display stands, brochure displays, display cases, perspex sweet dispensers, to name a few items. View the companies that offer perspex fabrication services.
Calendering Plastics
Calendering is a finishing process applied to textiles and plastic. During calendering rolls of the material are passed between several pairs of heated rollers, to give a shiny surface. Extruded PVC sheeting is produced in this manner as well other plastics. Calendering is a final process in which heat and pressure are applied to a fabric by passing it
