PROCESS FOR STAMPING DETERGENT BARS

摘要

PURPOSE: In a device for handling plastic material, such as a stamping device for stamping detergent bars, an elastomeric layer is provided on the handling surface which has good adhesion to the handling surface and good release from the plastic material. CONSTITUTION: The elastomeric layer comprises at least two elastomeric coatings of different properties and/or compositions. The process for forming an elastomeric coating on a device for stamping or handling a plastic material comprises the following steps of: treating the device by chemical and/or mechanical means to form a bonding surface for the elastomeric coating; forming on the bonding surface a first solidified elastomeric coating of selected composition under selected conditions; and forming on the first solidified elastomeric coating at least one second solidified elastomeric coating of separately selected composition under separately selected conditions.
