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…

Rapid prototyping technology combined with technologies such as scientific computing visualization and virtual reality provides a new measurable and touchable approach between designers, manufacturers and…
Current Status Of Rapid Prototyping Technology The United States is the world’s most important producer of RP equipment, and its RP development level and trends basically represent the world’s RP development level and trend. 1.Stereoscopic light modeling 3D Systems’ SLA27000 model has a scanning speed of 9.52m/s and a layer thickness of up to 0.025mm.…
The Status Quo Of 3D Printing Rapid Prototyping Technology Z Corp in the United States and Riken Institute in Japan have developed RP devices based on inkjet printing technology that can produce color prototypes. The system uses four different colors to produce eight different tones. The prototype can show the thermal stress distribution in three…
Effect Of Cooling Effect And Production Efficiency Of Injection Mold In the injection molding process, the cooling process plays a very important role in the quality of the molding, because it directly affects the production efficiency of the injection molding and the intrinsic performance and apparent quality of the injection molded product. The excellent cooling…
The Effect Of The Hardness And Life Of The Cold Work Die The main failure types of cold working molds are overload failure and wear failure, accounting for 80%-90% of the total failure. Cold heading die is mainly caused by cracking or abnormal wear (partial shedding), cold extrusion die is mainly brittle or wear failure,…
Analysis Of Materials And Performance Requirements Of Cold Work Die Mold is an important basic process equipment in manufacturing technology. The quality of mold products is not only related to the quality and performance of the products, but also directly affects the manufacturing cost and efficiency. In the mold products of the automobile, home appliance,…
Injection Molding Can Improve The Appearance Of Injection Molded Parts Cold/hot mold injection molding technology can greatly improve the aesthetics of injection molded parts. This process contributes to the improvement of the appearance of semi-crystalline and amorphous resin articles, particularly for amorphous resins. In the injection phase, when the surface temperature of the mold exceeds…
