John Bozzelli is the founder of Injection Molding Solutions (Scientific Molding) in Midland, Mich., a provider of training and consulting services to Calculate Shot Size Vs. Barrel Capacity.To create a clean break, gate geometry and gate land were critical. I saw there was nothing consistent in gate geometry between material or part size from mold to mold. I saw large parts with gates half the size of the gates on a smaller part running the same material. Injection pressure The proper injection pressure depends largely on part size and configuration. Pressures usually range from 800 to 1,500 psi. 1 st-stage pressure should be high enough to fill ~99% of the part and to avoid problems with shrinkage, voids, sinks, and short-shots. Too much pressure can cause parts to flash, Compression Molding A method of molding in which the molding material, generally preheated, is placed in an open heated mold cavity, the mold is closed with a top force, pressure is applied to force the material into contact with all mold areas, and heat and pressure are maintained until the molding material has cured. ,The calculator will find the eigenvalues and eigenvectors (eigenspace) of the given square matrix, with steps shown.
