Injection Moulding Machines

Sandwich Injection Moulding Machine – Series FB-C: 110~450


Sandwich injection moulding machine allowing simultaneous injection of different materials through the same nozzle.


Sandwich injection moulding is one of the newly developed injection moulding methods. To accomplish such a moulding method, an additional barrel is added to a traditional plastic injection moulding machine to form an independent double barrel with specially designed nozzle.


During the injection process, this double barrel can concurrently inject two types of molten plastic, via the same nozzle, into the mould to achieve two material simultaneous injection. The outer layer of the mixed molten plastic is called the skin material, while the inner layer is called the core material.
