ISO 294-3 Plastics - Injection Molding of Test Specimens from Thermoplastic Materials - Part 3: Standard Test method for Small Plates

EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of ISO 294-3 testing. This standard specifies two two-cavity molds, D1 and D11 type ISO molds, for the injection molding of 2 mm × 12 mm small plates with a preferred thickness of 60 mm (type D60) or 11 mm (type D12). It can be used for various tests. In addition to the dies, inserts can be fitted to study the effects of weld lines on mechanical properties.

Doors that are severely restricted in height have a great influence on the orientation of the material in the cavity, even at great distances from the door. The change in height at the door is therefore fixed at a value that facilitates the subsequent measurement of molding shrinkage.

The height and length of the gate strongly influence the solidification process of the melt as it flows into the cavity, and thus the mold shrinkage. The dimensions of the door are therefore defined with tight tolerances.

Many factors in the injection molding process affect the properties of molded test specimens and therefore the measured values ​​obtained when the specimens are used in a test method. The mechanical properties of such samples are highly dependent on the conditions of the molding process used to prepare the samples. The precise definition of each of the main parameters of the molding process is a basic requirement for repeatable and comparable operating conditions.
