A Background on Plastic Moulding

Plastic moulding refers to the process of shaping a pliable material, usually plastic with the use of a rigid frame or the mould. This is a manufacturing process that enables the creation of products or parts of any shape and size. The process allows for a wide range of design flexibility from the simple to the highly complex. This manufacturing process is used by all companies creating plastic products. Plastic moulding techniques are used to create various products such as containers, car parts, street signs, and many other items, particularly those that would need to be mass produced. If you are on the lookout for plastic moulding, NSW will not disappoint you. The plastic moulding industry in the state is very much alive.

There are a number of plastic moulding techniques that all operate under the concept of filling a hollow mould with liquid plastic so it takes on the form of the mould. Depending on the plastic material used different ranges of heat and pressure is required. The different types of plastic moulding techniques include injection moulding, rotational moulding, compression moulding, and blow moulding, among others. Each of these techniques comes with its own benefits and limitations and each of them is used according to the properties of the items that need to be produced.

Rotational moulding is one approach to plastic moulding. It was developed in the mid-20th century in the United States and was used for creating a limited number of plastic products. In the late 1950s, the rotational moulding technique found application for a number of industries including marine buoys, road cones, and car armrests. In the 1960s a new process was developed in Europe which enabled the manufacture of huge hollow containers made from low density polyethylene. This is done by rotating the mould in a chassis that can house open gas jets, which coats the interior of the mould with the plastic material.

On the other hand, plastic injection moulding has been around since as far back as the 1800s. It has witnessed continuous growth since then. This plastic moulding technique was used initially to produce buttons, and hair combs but will later on spread to other industries such as consumer goods, medical, aerospace, and medical products.
