<p>Plastics sample plate (1) is produced by injection molding, and has flat panel to carry at least two and preferably at least four test zones (3-6). The zones show the performance of the material during injection molding to give the characteristics for shrinkage, distortion, pinholes, replication of applied patterns or images, transparency, removal from the mold, and flow behavior around obstacles within the mold. The plastics sample plate (1) is produced by injection molding, and has a flat panel to carry at least two and preferably at least four test zones (3-6). The zones show the performance of the material during injection molding to give the characteristics for shrinkage, distortion, pinholes, replication of applied patterns or images, transparency, removal from the mold, and flow behavior around obstacles within the mold. The sample plate has zones (21CH,24CH) of different surface roughness or coarseness. A recessed zone (12) can contain a mirror. The evaluations can be written on to the sample for reference.</p> |
