Rubber Moulding

When creating your own products you'll need a plan beforehand. Once you're happy that you will know which type of rubber you need and have obtained this rubber, it's time to put it to use!

Depending on which product you plan on creating, you'll need to either create or purchase a mould. Since the release of 3d printers, you'll notice that the costs of the rubber moulding process have been greatly reduced. Choosing which method you choose to carry out when creating your product is imperative beforehand to ensure that everything runs seamlessly.

Custom Rubber Moulds

Typically manufacturers would use one of the following rubber moulding techniques:

Compression Moulding: 

When looking to manufacture large and intricate parts you will most likely be using a compression moulding technique to craft these.

Compression moulding is a method of rubber moulding whereby the material is preheated and placed in an open, heated mould cavity.

This method is best used for large parts where flawless finishes aren't necessary.

Transfer Moulding: 

When carrying out the Transfer moulding (BrE moulding) process, the casting material (in this case, rubber) is forced into the mould.

Transfer moulding contrasts compression moulding due to the fact that the mould is enclosed, opposed to the compression moulding technique whereby the mould is open.

As the mould is closed, you will be less susceptible to environmental impact and the end product will maintain a higher dimensional tolerance.

Injection Moulding

Injection moulding BrE or Injection moulding AmE is exactly as it sounds. This manufacturing process is used for producing parts and can be carried out using a whole range of casting materials.

The injection moulding process is carried out by injecting molten material into a mould and is most widely used for when you need to create a variety of parts, from small to large.

When using the injection moulding manufacturing process you must ensure that you take in to account the material used, the desired shape and any particular features that you would like to include before going head with it. Injection moulding is one of the most versatile moulding techniques.
