A Rubber Moulding UK company, such as https://www.meadex.co.uk/rubber-moulding/ will produce hundreds if not thousands of items each year. These can be moulds that will be used in the aerospace industry, or perhaps in the medical sector. Although their end destination may differ, the process by which the items are made tend to be the same. There are a number of different processes that include:

Compression Moulding – this is the process that is favoured when large volumes of the same item are required. It is an incredibly cost effective process and has very little waste attached to it. A two part mould is used which is both heated at the same time and has pressure applied to it. Rubber can then be formed into the required shape.

Transfer Moulding – Untreated rubber is taken from a transfer container where it is cured or vulcanised in the mould, depending upon its needs. This is where heat and pressure are applied to the mould.

Injection Moulding – An injection barrel forces rubber in the mould, allowing for the rubber to reach into small areas and into difficult shapes. Pressure is added to the mould whilst the rubber item is formed. This can be a great way to produce large numbers of items at a time and it is an incredibly fast process with a quick curing time.
