Process Evaluation For Multicolor Injection Molding Two-color injection molding is a very mature molding process. In the initial stage of mold development, analog analysis can be performed by various CAE software. The analog operation of the model can accurately determine the mold and various parameters of the molding. 1.Material analysis The analysis of materials is…
Current Status Of Other Rapid Prototyping Technologies Precision Optical Manufacturing (POM) of Michigan, USA, is developing Direct Metal Deposition (DMD) technology, which can produce metal parts with uniform texture and high strength by laser melting metal powder. The precision RP equipment developed by the National Aeronautics and Space Administration (NASA) can be used to process…
Double Material Injection Mold Design The general two-material product can be manufactured by a single-color injection molding machine. Basically, one injection molding machine can be used. However, the post-processing process is quite time-consuming and complicated, directly affecting the quality of the product, and the total production cost is not economical. In addition to the corresponding…
Advantages Of Two-Shot Co-Injection Molding Nowadays, the styles of consumer products are ever-changing. They must be beautiful in appearance and exquisite in design, and they must quickly meet the market demand. Designers generally use different materials in different parts of the consumer product for different purposes to meet the needs of specific environments, to extend…
Multi-Color Injection Molding Process Requirements 1. Soft and hard plastic two-color design The two materials must have a certain temperature difference in the melting point. Generally, it is recommended to reach 60°. It is recommended to be at least 30°. The melting temperature of the first shot material is high. Generally, the first shot is…
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…
