ABSTRACT:
An apparatus and method for cutting elastomeric material into volumetric elastomer samples is disclosed. These volumetric samples may be reproduced at identical mass for precision testing purposes. The volumetric samples are reproducible for such precision purposes by the use of a volumetric adjustment mechanism which determines the volume of the cavity into which elastomeric material is compressed before cutting. The apparatus also has a moving cutting mechanism with a contoured cutting area, which in combination with the volumetric adjustment apparatus, removes deleterious air bubbles and other deformities prior to cutting the elastomeric material. The volumetric adjustment apparatus is housed within a die apparatus, which has a damping mechanism to permit complete manipulation of the elastomer prior to cutting the elastomer into the volumetric plug. After the cutting of the plug has occurred, the ejection apparatus pushes the volumetric plug from the cavity whereupon another cycle is begun. The apparatus may also treat and cure uncured elastomeric material within the volumetric cavity by the application of heat sources to the apparatus surrounding the cavity.
