Typically it involves the melting of a plastic from pellet shape through an extruder. The plastic is melted to soften and then goes through a die to give it it's shape. It can be blown film, sheet extrusion, injection molded, blow molded, etc. Depending on the type of process used depends on the final product.
Blown film and sheet extrusion usually make either rolls of flat film, or cut to length sheets. Injection molded, and blow molded parts can make things like buckets, chairs, to small medical devices.

What are the shape and size of manufactured fibers determined by?
The shape and size of manufactured fibers are determined by the extrusion process used during production, specifically the design of the spinneret, which is the device that shapes the molten polymer into filaments. The diameter of the filaments can be controlled by adjusting the flow rate of the polymer and the size of the spinneret holes. Additionally, the post-extrusion processes, such as stretching and heat setting, can influence the final characteristics of the fibers, including their cross-sectional shape and thickness. These factors collectively affect the fiber's properties, such as strength, texture, and appearance.
How do you make an interconnected polymer foam having micro porosity?
To make an interconnected polymer foam with micro porosity, a polymer solution is typically mixed with a blowing agent and then subjected to a foaming process such as injection molding or extrusion. During this process, the blowing agent expands creating bubbles within the polymer matrix. By controlling parameters such as temperature, pressure, and cooling rate, you can control the size and distribution of the pores in the foam.
What is polymer processing?
Polymer processing refers to the methods used to convert raw polymer materials into finished products, such as plastic packaging, car parts, and medical devices. This can involve processes such as extrusion, injection molding, and blow molding, which shape and form the polymers into desired shapes and sizes. These processes are crucial for manufacturing a wide range of products that we use in our daily lives.
Extrusion in a sentence?
Extrusion is a manufacturing process where material is pushed through a die to create a specific shape or profile.
Is a diamond a polymer?
polymer
What is Blow up ratio in film extrusion?
Blow up ratio is a number that refers to the ratio of a blown film bubble diameter to the extrusion die diameter. The blow up ratio can affect the polymer molecules.
What has the author A Whelan written?

What is die swell phenomenon in the extrusion process?
When polymer exits the die of the extruder it will swell, this action is referred to as die swell. Thanks me later :P
What do you mean by extrusion fiber?
Extrusion fiber refers to a type of synthetic or natural fiber produced through the extrusion process, where a polymer or material is melted and forced through a die to create continuous strands. This method is commonly used in the production of fibers such as nylon, polyester, and polypropylene, which can then be spun into yarns or used in various applications like textiles, composites, and filtration. The extrusion process allows for precise control over the fiber's diameter, structure, and properties, making it a versatile manufacturing technique.

What tells geologists how extrusion forms?
I am learning about this in my Science class, and when a geologist looks at an extrusion, they know it's an extrusion because it is Igneous rock, and an extrusion helps tell the reletive ages of the layers around it.
