The Injection Moulding IML Process
The raw plastic, or resin material, is first fed into the hopper, which funnels it into the injection barrel, or the heating barrel.
The plastic is heated in the injection barrel, and then fed to the mould via the nozzle, using high pressure injection.
The plastic is at the right temperature for appropriate viscosity when it is transferred to the mould to be reshaped, taking on the shape of the mould. The mould is held tightly closed by the clamp system at this stage of the process. Whilst in the mould, the label is applied, inseparably linking it to the finished part before the mould opens and ejects the newly shaped plastic product.
Injection moulding IML differs from other plastic packaging manufacturing techniques in that it performs the process of producing the finished plastic product, with the label in place in one single step. This ensures the label takes the shape of the entire product, and allows for superior quality decoration.
