Injection moulding overview

Table 3.2 is an overview the injection moulding temperature windows recommended in practice are given in Table 3.3. 

The dosing system for liquid silicone rubber, which was described previously, is designed for only one machine. In order to save costs on space and investments, central material supply units are also available. Here, multiple injection moulding machines are supplied from one dosing system. Modem material conveyance systems operate on the concept of central material supply with a decentralised supply by volume at every injection moulding machine. Figure 7.8 depicts this type of system in a schematic overview. 

Whilst injection moulding can be considered a relatively young manufacturing technology, many variants of the basic process have been developed. Examples include processes such as injection-compression, gas assisted, water injection, co-injection and over-moulding. Each of these processes are suitable for specific market applications. An overview of the technologies covered in this chapter is shown in Figure 10.1.
