How does an extrusion moulding machine function?

It has a (usually metal) die in the shape of the moulding's profile. Clay is forced through the die producing the required shape, and is cut to manageable lengths before being fired in a kiln to harden it.

What are the processing techniques for short fiber thermoset composites?

Common processing techniques for short fiber thermoset composites include compression molding, injection molding, and resin transfer molding. These methods involve heating the composite material to a specific temperature to cure the resin and mold it into the desired shape. Each technique has its own advantages and limitations depending on the specific application requirements.


What are the advantages of injection molding compared to extrusion blow molding?

They are basically 3 entirely separate methods for forming plastic. Injection moulding - Plastic is injected into a tool. The plastic forms the inverse shape of the form in this tool. Shape is limited by the need to get the part out of the tool. Examples of items manufactured - Lego bricks, plastic bottle tops, electrical enclosures, etc. Extrusion - Plastic is ontinuously forced through a die (hole) to form long continuous forms. Examples pipes, insulated wires, etc. Blow Moulding - A preform is manufactured, typically by injection moulding. This form is then moved automatically to a second tool whilst it is still hot. Whilst in this 2nd tool gas is "blown" into the centre of the preform which stetches it to the form of the 2nd tool. This allows hollow items to be manufactured like bottles. There are other methods of processing plastic. See links.


What are the advantages of extruded plastics?

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.


What environmental impact does extrusion moulding have?

Extrusion moulding can have several environmental impacts, primarily related to energy consumption and waste generation. The process typically requires significant energy input, contributing to greenhouse gas emissions if fossil fuels are used. Additionally, the production of plastic materials can lead to resource depletion and pollution, while improper disposal of extruded products can result in plastic waste accumulation in landfills and oceans. However, advancements in recycling technologies and the use of biodegradable materials are efforts to mitigate these impacts.
