What Are The Advantages Of Making Molds With 3D Printing? 1. Mold production cycle shortened 3D printing molds shorten the entire product development cycle and become the source of drive innovation. In the past, companies sometimes chose to postpone or abandon design updates for new products, given the large capital investment required to create new…
DetailsMold Polishing Work Environment The polishing process should be carried out separately at two working locations, that is, the rough grinding processing location and the fine polishing processing location are separated, and care should be taken to clean the sand particles remaining on the surface of the workpiece in the previous process. Generally, after rough…
DetailsMatters Needing Attention During The Polishing Process Of The Mold Surface 1. When a new cavity begins to be processed, the surface of the workpiece should be inspected first, and the surface should be cleaned with kerosene so that the surface of the oilstone does not stick to dirt and the function of cutting is…
DetailsTen Surface Treatment Technologies For Forging Dies The treatment technology that uses modern technology to change the surface, subsurface composition, structure and properties of the forged mold is called surface modification technology, and mainly includes the following ten categories: 1.Electrochemical transformation The technique of forming an oxide film on the surface of a part in…
DetailsHow To Judge Whether The Mold Is Invalid? Mold failure refers to the loss of normal working ability of the mold, and refers to the phenomenon that the working part of the mold is seriously worn or damaged and cannot be re-commissioned by the general repair method (sharpening, polishing). Die life refers to the number…
DetailsFactors Affecting The Polishability Of The Mold Surface 1. Surface condition of the workpiece During the machining process, the surface layer may be damaged by heat, internal stress or other factors, and improper cutting parameters may affect the polishing effect. The surface after EDM is more difficult to grind than the surface after machining or…
DetailsHow To Solve The Problems In Yhe Mold Polishing Process 1.Over-polishing The biggest problem encountered in the daily polishing process is “over-polishing”, which means that the longer the polishing time, the worse the quality of the mold surface. There are two phenomena of over-polishing: “orange peel” and “pitting”. Excessive polishing occurs mostly in mechanical polishing.…
DetailsCommon Mold Polishing Methods And Working Principle In the mold manufacturing process, smooth processing and mirror processing after shape processing are called surface grinding and polishing of parts, which is an important process to improve the quality of the mold. Mastering a reasonable polishing method can improve mold quality and service life, thereby improving product…
DetailsReasons For Color And Gloss Defects Of Injection Molded Products Under normal circumstances, the gloss of the surface of an injection molded part is mainly determined by the type of plastic, the colorant and the finish of the mold surface. However, due to some other reasons, the surface color and gloss defects of the product…
DetailsCauses Of Warpage Of Injection Molded Products The deformation, bending and twisting of injection molded products are mainly caused by the fact that the shrinkage rate of the flow direction during plastic molding is larger than that of the vertical direction, so that the shrinkage ratio of the parts is different and warped, and it…
