Profile extrusion or extrusion profiles in Melbourne is manufacturing a shaped product with a consistent cross-section. Common items like PVC pipes, rain gutters, straws, weather stripping, deck railings, wire insulations, fencing, plastic films etc are made through this process.
Melted plastic is pressed through a die (an accessory that can give correct shape and acts like a mould) that is in the desired shape. Depending on the raw material, the final product is rigid, semi-rigid or flexible. Many companies use this method for manufacturing mainly for the following reasons.
- Low cost: Extrusion is a low-cost manufacturing process, compared to another moulding process. The objects made through this process are thermoplastics that can be recycled and used repeatedly, thus reducing the low material and disposal costs.
- Flexibility: Extrusion provides considerable flexibility in making products that have a uniform cross-section. If the cross-section of the object is uniform, whatever may be the complexity level, they can be manufactured through this process.
- Post-extrusion alteration: The plastic is generally hot when it leaves the extruder, which allows for modifications and manipulations. Variety of rollers, dyes can be used to alter the shape of the extruded plastic to fit their needs.
It is very important to use a proper mould and heat plastic to the required temperature to get satisfactory outcomes.
