Special Lost Foam Casting Technique-noreply

0 Comment

Business Special lost foam casting technique is a new lost foam casting technique which .bines the lost foam casting technique to the other techniques. It is an accurately fresh technique. It uses bondless sand molds in order to lesson pollution, so it is considered as "green casting industrial art" in the 21st century. Several kinds of lost foam casting technique: 1. Pressure lost foam casting technique Pressure lost foam casting technique is a new technique which connects lost foam casting technique with pressure concretion crystallization technique. The advantage is that it can reduce the defect of casting such as casting porosity, ripple and shrinkages, so it can increase the density of casting and improve the mechanical properties. 2. Vacuum low tension lost foam casting technique Vacuum low tension lost foam casting technique is a re.bination of low tension anti-gravity pouring technique and negative pressure lost foam casting technique. The characteristics are that the equipment investment is less, the casting cost is lower and the casting heat treatment is more strengthened than die casting. .paring to sand casting, its accuracy is higher, production rate is higher and property is better. 3. Vibrated lost foam casting technique Vibrated lost foam casting technique is a technique that adds some certain frequency and amplitude of vibration during the process of lost foam casting to make casting concrete under the vibrant field. This technique can reduce rough and increase property. Its processing is simple, cost is low and no pollution. 4. Semi-solidity lost foam casting technique It is a new technique which .bines lost foam casting technique with semi-solidity technique, so it can control the relative rate of liquid and solid state. This technique can increase the density and size accuracy of casting and improve the casting property. 5. Lost foam suspension casting technique It .bines lost foam casting technique and suspension casting technique. The suspending agent is added to metal liquid to produce a chemical reaction to increase the casting property. The advantages are that the design is flexible, clean and environment protection. It fits to .plex casting and has a wide perspective in the new century. This article was from Dandong Foundry. For the whole article, please check Dandong Foundry Blog. About the Author: 相关的主题文章:
