Key technical points of casting pouring process
一、Five important details that are easily overlooked in lost foam casting 1. Pressure head height; 1) In order to ensure the highest and farthest part of the casting, and obtain a casting with clear contours and complete structure, the height from the highest point of ...Read more -
What are the characteristics of the casting process? What kind of products are suitable for processing?
Casting processing is a process in which molten metal liquid that meets the requirements is poured into a specific casting mold, and the desired shape, size, and performance are obtained after cooling and solidification. It is widely used in aerospace, automobile, machin...Read more -
Study on Heat Treatment Technology of ZG06Cr13Ni4Mo Martensitic Stainless Steel Blades
Abstract: The influence of different heat treatment processes on the performance of ZG06Cr13Ni4Mo material was studied. The test shows that after heat treatment at 1 010℃ normalizing + 605℃ primary tempering + 580℃ secondary tempering, the material reaches the best perfo...Read more -
Grapevine: 10 knowledge points about die-casting molds!
Knowledge point one: Mold temperature: The mold should be preheated to a certain temperature before production, otherwise it will be chilled when the high-temperature metal liquid is filling the mold, causing the temperature gradient between the inner and outer layers o...Read more -
Turbine vs impeller, is it the same thing?
Although turbine and impeller are sometimes used interchangeably in everyday contexts, in technical and industrial applications their meanings and uses are clearly distinct. A turbine usually refers to a fan in a car or airplane engine that improves engine performance by...Read more -
Talk about the role of each element in gray cast iron
The role of commonly used elements in gray cast iron 1.Carbon and silicon: Carbon and silicon are elements that strongly promote graphitization. Carbon equivalent can be used to illustrate their effects on the metallographic structure and mechanical properties of gray ...Read more -
10 principles to reduce casting defects!
In the production process, foundry companies will inevitably encounter casting defects such as shrinkage, bubbles, and segregation, resulting in low casting yields. Re-melting and production will also face a large amount of manpower and electricity consumption. How to re...Read more -
What is high silicon heat-resistant cast iron? How does the production process operate?
By adding a certain amount of certain alloying elements to cast iron, alloy cast iron with higher corrosion resistance in some media can be obtained. High silicon cast iron is one of the most widely used. A series of alloy cast irons containing 10% to 16% silicon are cal...Read more -
Calculation of Casting Cooling Time
In order to prevent castings from deformation, cracks and other defects due to rapid cooling after pouring, and to ensure that castings have sufficient strength and toughness during sand cleaning, castings should have sufficient cooling time in the mold. Continuously produced castings should be d...Read more -
Knowledge – How to improve the appearance finish of castings?
一、 Common causes affecting casting surface finish 1. The shape of raw materials, such as molding sand, is divided into round, square and triangular. The worst is triangular, with particularly large gaps (if it is resin sand modeling, the amount of resin added will also increase, and of course t...Read more -
What are the characteristics of several common casting processes, and what castings are suitable for them?
Introduction Casting is the earliest metal thermal processing technology mastered by humans, with a history of about 6,000 years. China has entered the heyday of bronze castings between about 1700 BC and 1000 BC, and its craftsmanship has reached a very high level. The material for the mold can b...Read more -
Which castings solidify layer by layer, which castings solidify in a paste state, and which castings solidify intermediately?
During the solidification process of a casting, there are generally three areas on its cross section, namely the solid area, the solidification area, and the liquid area. The solidification zone is the area where “solid and liquid coexist” between the liquid zone and the solid zone. I...Read more
