The dimensional stability of injection moulded articles is very critical. The so called mould shrinkage is something you would need to know. Intertek has the capability to support your material development in this area. Intertek specialists have a broad range of injection moulding machines and a number of moulds at their disposal.
For very accurate determination of dimensional properties and Mould Shrinkage, we operate a 3-D measuring device (3-D CNC measuring machine).
The accuracy (Size-dependent) is about 4 µm. The method is based on ISO 294-4. Typical dimension of an injection moulded plaque to determine the mould shrinkage, would be 65x65x3.2 mm or 80x80x2.2 mm.
