The purpose of bakelite phenolic resin modification is mainly to improve its brittleness or other physical properties, improve its adhesion to fiber-reinforced materials and improve the molding process conditions of composite materials. Modification is generally through the following channels: ① Block...

Bakelite is the first plastic product to be put into industrial production. The chemical name of bakelite is phenolic plastic. It has high mechanical strength, good insulation, heat resistance and corrosion resistance. The shortcomings of phenolic resins are poor mechanical...

Tool and die Machining Process Performance The manufacturing of the mouldgenerally goes through several processes such as forging, cutting, and heat treatment. In order to ensure the manufacturing quality of the mouldand reduce the production cost, the material should have...

In the mould manufacturing, mouldselection is a very important part of the entire mould manufacturing process. The selection of materials for the mouldneeds to meet three principles. The mould meets the work requirements of wear resistance and toughness. The mould meets the process...

Small moulddensity: The low density of plastics is of great significance for reducing the weight of machinery and equipment and saving energy, especially for vehicles, ships, aircrafts, and spacecraft. High specific strength and specific stiffness: The absolute strength of plastics...

Mould manufacturingshould pay attention to the concise process preparation and detailed expression, and the processing content should be expressed numerically as much as possible; At the key and difficult points of processing, the process should be specially emphasized; The combination...

Die machining process arrangement Bottom surface processing, guaranteed machiningvolume; The casting blanks are aligned and the 2D and 3D profiles are checked; Rough machining of 2D and 3D profiles, non-installation and non-working plane machining (including safety platform surface, buffer installation...

(1) The precision of die machining is high. The auxiliary mouldis generally composed of a concave mold, a convex mouldand a mouldframe, and some may also be a multi-piece assembly module. Therefore, the combination of the upper and lower molds, the...

The processing technology of CNC Swiss lathe is similar to that of ordinary lathes, but since CNC lathes are clamped once, all automatic turning processes are completed automatically, so you should pay attention to the following aspects. 1. Reasonable choice...

cnc swiss machining problems The die belt will cause the scrap to rebound, and its related factors: ① the sharpness of the die blade, the larger the fillet of the blade, the easier it is to cause the scrap to rebound....
