There are a number of advantages for plastic extrusion machines or plastic extrusion modelling itself. These include low cost relative to other models, flexibility to manufacture products with a consistent cross section and the ability to make alterations or modifications after the process is complete.
Wikipedia has an whole article on the topic thermoplastic extrusion. Thermoplastic extrusion is a high volume manufacturing process in which raw plastic material is melted and formed into a continuous profile.
Some applications of plastic extrusion are: 3D printer filament. compound extrusion to make pellets, extrusion coating, straws, medical tubing, wires, juice cartons, wine boxes, food packaging, shopping bags, water bottles, to name a few.

There are many key processes in plastic manufacturing. Injecting molds is the most common way to make something out of plastic. Extrusion molding is also another way to manufacture things out of plastic.
Some disadvantages of the hot extrusion process include high equipment and maintenance costs, limited material choices due to temperature constraints, and potential for material contamination from high temperatures. Additionally, achieving precise dimensional accuracy can be challenging in hot extrusion.

Extrusion can be used to create a variety of products, including plastic pipes, automotive parts, aluminum profiles, and food products like pasta and breakfast cereals. It is a versatile manufacturing process that can produce complex shapes with a uniform cross-section.
In plastic welding, equipment used includes plastic welders (some are ultrasonic) and as with any type of welding, protective equipment such as gloves.
Whether you’re working on a DIY project, setting up industrial equipment, or designing custom furniture, the right choice of aluminium extrusion profiles, especially T-slot aluminium, can make your work easier and more efficient. Here’s a guide to help you select the perfect aluminium extrusion profiles for your needs.
Malleability of plastic refers to its ability to be easily shaped or molded without breaking. This characteristic allows plastic to be formed into various shapes and sizes through processes like extrusion, injection molding, and thermoforming.
In a plastic factory, raw plastic material is processed and shaped through heating, molding, extrusion, or injection molding techniques. Additives such as colorants, stabilizers, and fillers may be mixed in to enhance the material's properties. Finally, the plastic is cooled and trimmed into the desired shape or form.
