Standard Practice for In-Line Screw-Injection Molding Test Specimens From Thermosetting Compounds

2019

4

ASTM Vol.08.02 (2022)

This practice covers the general principles to be followed when injection molding test specimens of thermosetting materials. It is to be used to obtain uniformity in methods of describing the various steps of the injection molding process and in the reporting of those conditions. The exact molding conditions will vary from material to material, and if not incorporated in the material specification, shall be agreed upon between the purchaser and the supplier or determined by previous experience with the particular type of material being used and its plasticity. NOTE 1: The utility of this practice has been demonstrated for the molding of thermosetting molding compounds exhibiting lower-viscosity non-Newtonian flow. The values stated in SI units are to be regarded as standard. The values given in parentheses are for information only.
