<html> <p>Plastic moulding is simply a process of shaping plastic with the help of a mould. The moulded parts are used in various industries for different applications. There are mainly two types of plastic categories:</p> <p><img src="http://4.imimg.com/data4/OB/VD/MY-3533420/injection-moulding-services-500x500.jpg" width="500" height="500"/></p> <p><strong>Thermosets plastic</strong>: Thermosets are hardened at high temperature and they always remain in a permanent solid state. Thermoset contain polymers that cross-link together during the curing process to create a permanent chemical bond. Products made of thermoset plastic are best suitable for high-heat applications such as electronics and appliances. Some of the key features of thermoset plastic include chemical resistance, heat resistance and structural integrity. The common examples of thermoset plastics include epoxy resins, polyester resin, etc.</p> <p><strong>Thermoplastics</strong>: Thermoplastics are softened at high temperature. They can be re-melted back into liquid form. Thermoplastics can be easily remolded and recycled without affecting the physical properties of the material. The key features of thermoplastics include high strength, shrink-resistance, easy to bend, etc. Some of the widely used thermoplastic are polystyrene, nylon, polypropylene and polythene.</p> <p>These days, different types of moulding processes are used to create a variety of products. Some of the most popular processes or methods include: Extrusion, Injection moulding and the Combination of extrusion and injection moulding</p> <p><strong>Extrusion</strong></p> <p>Extrusion is a manufacturing process in which raw plastic is used to produce things like hoses, pipes, drinking straws, films, sheets, rods, etc. the plastic is fed into a gyrating chamber. In this chamber, the plastic is melted and is shapes in various designs as per the application requirement. The end product is dropped on the conveyor belt to let it cool down with water and form a solid shape. After cooling down fully, the product is cut and the finishing touch is give to it. </p> <p><strong>Injection moulding</strong></p> <p>Another most popular method of plastic moulding for the fabrication of plastic parts is the injection moulding. An injection molding process requires the use of an injection molding machine, raw plastic material, and a mold. Under this method, the raw plastic is fed into the melting chamber with the help of a hopper. The melted plastic is then injected into a cold mould with high-pressure. In order to create a clean and refined shape, the mould should be cool. Key stages involved in the process of plastic injection moulding are the clamping, injection, cooling and ejection. A number of thermoplastics can be processed with the help of injection moulding process. The most common materials used in this process include Acrylonitrile-Butadiene-Styrene (ABS), Nylon (PA), Polycarbonate (PC) and Polypropylene (PP). The variety of items that are made using <a href="http://www.baytechplastics.com/injection-moulding">custom injection moulding</a> process include toys, bottle caps, containers, furniture, etc. </p> <p><strong>The Combination of extrusion and injection moulding</strong></p> <p>In the combination of extrusion and injection moulding process, a blowing method is used after the extrusion or injection molding.</p> <p>All the above mentioned processes are some of the most popular and widely used manufacturing processes used throughout the world. These are undoubtedly the most versatile methods of producing various plastic parts and products. </p> </html>
