Because for complex castings, especially for thin-walled castings with complex shapes and produced in small batches, casting has always been a problem. What's more, customers now have high requirements for short cycle and low cost, and traditional craftsmanship is difficult to handle. ...
Casting coatings are applied to most of the casting production process and play an important role in the surface quality of castings. There are many foundry coating manufacturers in my country, with large differences in production scale and uneven product quality. For casting manufacturers, it is ve ...
The emergence of water glass has a history of more than 300 years, but as a binder for casting and core making, it was not until 1947 that the water glass sand process with CO2 as a hardening agent was developed by Dr. L. Petrzela of the Czech Republic. of. ...
Front-line employees are the biggest difficulty in enterprise production management, and they are also the focus of discussion in all current management theories. Especially in recent years, the proportion of post-90s employees in the workshop has gradually increased. Around the "people" factor, com ...
In the entire manufacturing process of steel castings, deformation occurs in almost every process. The causes of casting deformation are mainly divided into two categories. One is internal reasons, which are mainly manifested as casting stress deformation and heat treatment stress deformation. ...
Due to the coarse grains, poor sound permeability and low signal-to-noise ratio of castings, it is difficult to detect flaws. It uses sound beams with high-frequency sound energy to propagate inside the castings, and when they encounter internal surfaces or defects, they reflect and find defects. ...
Furnace knotting is an important process in the smelting and casting of intermediate frequency induction furnaces. Over the years, the repetition of knotting the furnace and purchasing the integral furnace has been unsatisfactory. We adopt the wet knotting technology of the intermediate frequency in ...
In recent years, the casting technology of aluminum alloy castings has been greatly developed, and the output of aluminum castings has been increasing year by year. Now it has been more and more widely used in the fields of weapons, aviation, aerospace, textiles, etc., and the quality requirements o ...
Automobiles use high-strength steel, which can reduce the thickness of the plate due to its higher strength, making the automobile structure lighter. At the same time, the car's dent resistance, durability and large deformation impact strength are improved, and the cost is lower than that of light m ...
Coarse crystal grains of castings refer to defects that show excessively coarse grain structure and unsuitable for application after mechanical engineering or fracture inspection. This coarse grain structure may be spread throughout the entire casting or may occur in the casting. ...
In particular, the rapid development of traditional and emerging industries such as automobile manufacturing, wind power generation, and metallurgical machinery, coupled with the new trend of international manufacturing shifting to China and Asian countries, has injected vitality and vitality into C ...
