What are the commonly used materials for injection molding

In injection molding, the following materials are commonly used: 1. Polystyrene (PS). Commonly known as hard glue, it is a colorless, transparent and glossy granular polystyrene with the following properties: a. Good optical performance b. Excellent electrical performance c. Easy to form and process d. Good coloring performance e. The biggest disadvantage is brittleness f. Low heat-resistant temperature (maximum use temperature 60 ~ 80 ℃) g. Poor acid resistance 2. Polypropylene (PP). It is a colorless, transparent or glossy granular material, referred to as PP, commonly known as hundred fold …

How is a qualified mechanical part manufactured？

The deformation of mechanical components is directly proportional to the complexity of shape, aspect ratio and wall thickness, as well as the stiffness and stability of materials. Therefore, in part design, the influence of these factors on workpiece deformation should be minimized. Especially for parts with large structure, more reasonable structure shall be adopted. Before machining, the hardness and looseness of the blank should be strictly controlled to ensure the quality of the blank and reduce the deformation of the blank to the workpiece Deformation caused by workpiece clamping For …

Japanese perverted precision processing, the battleship model that can only be seen with a microscope is amazing

In modern industry, machining is a measure of a country’s manufacturing level, and precision machining and ultra-fine precision technology, but also represents the highest level of machining, whether the mastery of these technologies represents the level of industrial manufacturing of the entire country. We all know that in the level of machining Germany should be the most powerful, this is because Germany has the most advanced machine tools, and very good and rigorous technical workers, in fact, in addition to Germany, Japan’s precision machining is also not to be underestimated, …
