In this modern world, plastics are now being used more than ever before. Plastics are used for all types of manufacturing processes; be it automotive, items for industrial use, commercial use, household use, and even for synthetic body parts. The plastic molding process is an interesting one to say the least, and there are several ways in which plastic is molded to create the perfect product.
The Types of Plastic Molding
Blow Molding: The process of blow molding is extremely similar to glass blowing. In this process, a pre-desired mold is chosen, where melted plastic is poured in. Then, the manufacturer blows air into the molten plastic to shape it to fit into the mold exactly, thus creating the desired hollow shape. This process is used to create hollow plastic items which have a variety of different uses in various industries. This process allows manufacturer to create objects like bowls, containers, cups, drums, etc.
Rotational Molding: This plastic molding process is similar to Blow Molding, with a slight difference, rotational molding can be used to create medium to large size objects in the same way that blow molding is done. In the case of rotational molding, the entire mold is rotated so that the molten plastic fills up each crevice of the mold, thus cooling down and taking the form of the mold where it was poured. Rotational molding process can be used for creating kayaks, road cones, recycling bins, utility bins, and much more.
Injection Molding: Injection molding is another form of plastic molding process. In this process of plastic molding, hot, molten plastic is injected into a metal mold, where it is then allowed to cool and taken out once the proper shape of the plastic has been created. Injection molding can be used to create more than 30,000 customized plastic item pieces in a year. It is a highly accurate and efficient process of creating plastic molds. Injection molding can be used to manufacture plastic caps, medical devices, and even electrical switches.
Compression Molding: Just as the name suggests, the process of compression molding requires a hot, molten plastic to be inserted into a heated mold, which is then compressed to allow the heated plastic to take the shape of the mold. Once the plastic has cooled off, the unnecessary parts are trimmed, and the plastic product is ready for use. Compression molding process can be used to manufacture parts such as small auto parts, automotive parts, fenders, hoods, and many others.
Thermoforming: The process of thermoforming is quite interesting and unique. Thermoplastic is a specific type of plastic which is used for this process. In this plastic molding process, the thermoplastic is heated up to a specific temperature where it is easy to manipulate the plastic into a specific shape or size. Different products, even customizable products can be created with it.
Thermoplastic comes in a variety of colours, sizes, textures and thicknesses, it is this versatile nature of thermoplastic that allows manufacturers to create different types of unique plastic products with it. Thermoforming allows manufacturers to create large quantity of items such as plastic cups, fridge liners, auto parts, lids, and many similar products.
Plastic molding process is useful for many different types of industries which make use of plastic to create different type of products with the help of these molding processes. With the help of experts, different types and forms of plastic can be easily molded to create many unique items which are being used for all types of different industrial, commercial and personal use. The plastic molding is a unique procedure which benefits people across the society.
