The Main Reason For The Difficulty Of Demoulding After Plastic Injection Molding After the injection molding of the plastic part, the plastic part is released from the mold cavity, and the ejection work is generally completed in one time, whether using a single or multi-element ejection mechanism. However, sometimes due to the special shape of…
Common Problems In Metal Castings And Related Prevention Methods 1.Pinhole Measures to prevent pinholes: (1) It is strictly forbidden to use contaminated cast aluminum alloy materials, organic compounds and materials that are severely oxidized and corroded. (2) Control the smelting process and strengthen the degassing refining. (3) Control the thickness of the metal coating, too…
High-Speed Heat Treatment On The Quality Requirements Of The Tool In practice, the upper and lower limits of the temperature generally correspond to the highest and minimum secondary hardening levels available, respectively. Of course, the temperature setting value of the meter should be selected according to the type and size of the workpiece and the…
Grinding Technology Essentials For CNC Coordinate Grinding Machines First, the grinding process is more complicated than other cutting processes. The cutting process of the abrasive grains includes three states of sliding, ploughing and cutting. The grinding process of the grinding wheel consists of three stages: spark cutting, stable grinding and spark cleaning. Second, the elastic…
