Plastics are everywhere and you encounter and use them in your daily lives on a regular basis. Pretty much everything can be molded from plastic. The ability of plastic to be shaped and moulded by heat has made it one of the most commonly used material in creating household as well as other items. This can be done through several ways such as through plastic injection moulds. This process involves producing parts through injecting the plastic into a mould. Plastic have different characteristics and behave differently at each stage of processing. The uses and applications also vary generally. There are different categories of plastics which include:
This type of plastic is used in bottle manufacture. It can be rigid or flexible depending on how it’s made. Common examples include soft drinks bottles and water bottles, cooking oil bottles and packaging trays.
It is a cost effective material. It is also highly resilient to chemical and biological damages. It is easy to mould it into various shapes and extremely practical. They are commonly used in furniture, medical containers, flooring, sewage pipes and cables.
High Density Polyethylene
It is incredibly strong and has a high density. It is able to handle high temperatures and strong chemicals. The advantage of HDPE is that it can be recycled in various ways. It is commonly used in food and drink storage, shopping bags, fuel tanks and insulation pipes.
Polypropylene is a very hard plastic that is strong and flexible; when melted, it can be used to make plastic injection moulds more effectively. It has a high tolerance to high temperatures in comparison to other plastics. It is also considered as a food safe material. Some common examples include clothing, bottle caps, straws, kettles and lunch boxes.
