Plastic Extruder For Sale In South Africa
What is Plastic Extruder ?
Plastics extrusion is a high-volume manufacturing process in which raw plastic is melted and formed into a continuous profile. Extrusion produces items such as pipe/tubing, weatherstripping, fencing, deck railings, window frames, plastic films and sheeting, thermoplastic coatings, and wire insulation.

Frequently Asked Questions
What does a plastic extruder do?
Plastics extrusion is a normally high volume manufacturing process where a polymer material, enriched with the desired additives, is melted and formed in a continuous process. The raw material (polymer) in the form of granulates, is gravity fed into the hopper and through the feed throat, drops on a rotating screw.
What is plastic extruder machine?
The Precious Plastic Extrusion machine is an open source machine to transform plastic waste into beautiful recycled beams, bricks and more. Anyone can build the Extrusion machine and make a business from recycling plastic. And thousands of people are already using it around the world.
What is an extruder used for?
It’s one of the most common ways to produce sheets and strips of stock metal, plastic and rubber shapes. An extruder is simply the machine used to complete the extrusion process. Using a system of barrels and cylinders, the machine heats up the product and propels it through the die to create the desired shape.
How does a plastic pipe extruder work?
An extruder converts raw plastic material into a continuous tubular melt by extrusion through an annular die. The molten pipe then proceeds through a sizing or calibration bench (which adjust its dimensions) to a cooling tank.
What is the principle of extruder?
An extruder is basically a screw pump; the screw(s) rotates in a tightly fitting stationery barrel. The semimoist feed or dry powder/grit is introduced into the extruder, usually at a constant rate of mass or volume employing a feeding mechanism. The material thus moves forward by the rotation of the flighted screw(s).
Where is plastic extrusion used?
Plastics extrusion is a high-volume manufacturing process in which raw plastic is melted and formed into a continuous profile. Extrusion produces items such as pipe/tubing, weatherstripping, fencing, deck railings, window frames, plastic films and sheeting, thermoplastic coatings, and wire insulation.
What extruder means?
: someone or something that extrudes something specifically : a machine that shapes material by forcing it through a specially designed opening a pasta extruder There are recipes too, and for those who don’t have a sausage extruder at home (who doesn’t?) some of the sausages don’t require casings.
What is extruder process?
extrusion, process in which metal or other material is forced through a series of dies to create desired shapes. Many ceramics are manufactured by extrusion, because the process allows efficient, continuous production.
What are the advantages of plastic extrusion?
Minimal waste production. Production of parts with complex cross-sections. Continuous operation capabilities, resulting in lower costs and faster turnarounds. Versatility with many types of raw materials, including both brittle and ductile plastics.
What products are made from plastic extrusion?
Six Plastic Extrusion Products
- Bottles and Straws.
- Bags, rails and holders.
- Car Parts.
- Toys.
- Sports Equipment.
- Irrigation Piping.
What is an example of extrusion?
A simple example of extrusion are the toys used when playing with playdough. The items that playdough is pushed through, in order to create a specific shape, is the die; and the process is called extrusion. In order for the die to create the desired shape, the material needs to be pushed through with force.
