Injection moulding is a form of manufacturing and is usually used to produce small plastic items that are large in number. For example, a car company would use this process to create all the small parts such as seatbelt holders, caps for fluid reservoirs and various other small plastic products.
Most of the time, a company will only use this type of manufacturing if they create a lot of small products that are exactly the same. So, in other words, if the company needs to produce a large range of duplicate items then injection moulding is the perfect solution.
The whole process is very powerful and very fast and this is why it’s so popular. A large machine does most of the work but it will need supervision from staff and possibly a technician. The whole process is very fast but is simple to understand.
To start with, a feeder places the granulated plastic into what they call a hopper and it is then fed through a heated barrel which melts the plastic. Once it is melted it can be mixed with other properties and solutions such as colour or whatever else is needed.
Once the plastic has melted and mixed it can then be fed into the mould part of the machine. Once all the product is inside the mould, the machine cools this area to set the mould. You will then be at the end of the process and will have the first of many plastic products created.
A lot of other factors are involved in keeping the machine running – for example, water is almost always used to cool the plastic while it’s inside the mould. There are also a variety of shapes and sizes available for the mould and most companies are required to make these moulds themselves.
Many people overlook injection moulding but it’s actually widely used by many large manufacturing companies throughout the world. The main reason that this process is so popular is because it is fast, accurate and very easy to set up – once you have the machine, you simply need to maintain it.
Injection moulding machines can be quite large so you’ll definitely need a warehouse, but chances are, if you’re a manufacturing company, you already have a large warehouse in place. Another reason why this form of production is so popular is because it’s cost effective as well.
Obviously, you do have the initial cost of purchasing the machine but they cost very little to run and are usually very stable in terms of not breaking down or malfunctioning. They can save a lot of time and money in the long run.
You should be able to find injection moulding machines in a variety of shapes and sizes and you can either buy them, used, from other companies who no longer need them, or you can buy them brand new from a manufacturing machine specialist.
You should definitely do some research before you buy anything because it can be a bit of a complicated process. Obviously, as a large manufacturer you’ll probably be able to use your contacts to get yourself a good deal for any number of machines and equipment options.
