Bright Precision Casting Foundry Information.
Application of Laser Forming and Casting
Fast automatic molding technology developed in recent years the rapid production directly from the cad model sample or part of the general term for group technology. The technology to solve a computer-aided design (cad) in the three-dimensional modeling of the “seen, touched,” the problem, the geometry of the screen can quickly auto-entity. It integrates cad technology, numerical control technology, laser technology and materials technology and other modern scientific and technologic...
Hollow turbine blade manufacturing process
Turbine blades is a key component of power equipment, the structure and materials continue to improve the human to improve energy efficiency, access to high-performance equipment (power equipment) and products (such as aircraft) of the key. Because it is in the highest temperature, stress the most complex parts of the environment was the worst as the first key pieces, and known as the “crown jewel.” Therefore, the manufacturing technology home and abroad as the past 20 years the majo...
Wax Casting Research and Development
Casting Wax index test results show that the newly developed model of the bending strength of material, surface hardness, linear shrinkage and ash and other indicators to the existing series of domestic enterprises wax casting standards, indicators in the temperature close to the Japanese k512 wax casting product standards , and has heat resistance, coating hanging, mobility and reusability good characteristics, to meet the needs of the domestic production of precision casting and mold materials...
The type of cast iron
1.Alloy Cast Iron Without prejudice to the principle of graphite structure, by adding sufficient amount of iron in the alloy elements (usually containing Cr, Ni, Cu, Mn and Mo in the one or several) to change the al-Qaeda, and to achieve a modest improvement in the physical and cast iron The purpose of the mechanical properties. Normal levels of raw materials, such as exists in Si, Mn, S and P are not as addition of alloying elements. 2.Cast Iron Mainly iron, carbon and silicon the general term ...
High alloy steel
High alloy steel began about half of the nineteenth century. 1883 British Hadfield (R0.A0.Hadfield) first obtain a high manganese steel of the patent, has been 100 years of history, high manganese steel is a high content of carbon and manganese content of the high alloy steel, this with a hundred year old steel, because of its large impact abrasive wear conditions, when used with a strong work-hardening capacity, while both good toughness and ductility, and easy to grasp the advantages of the pr...
Cast high-alloy steel
In the casting of high-alloy steel, adding a total of 10% of alloying elements (mass) or more alloying elements can be added one, two, or more species. Contains large amounts of alloying elements in steel, the organization has been a fundamental change. Makes the use of steel with special properties, such as ωMn = 13% of the austenitic high manganese steel with high impact wear performance, and if ωcr = 18%, ωNi = austenitic stainless steel, with good resistance to Rot and so, therefore, is actu...
Low-alloy steel casting
In machinery manufacturing, a common low-alloy steel casting including manganese, chromium and nickel three series. The series is in the casting of steel based on the composition of carbon steel casting alloy and heat treatment by phase to in order to obtain a higher temperature than the cast steel, mechanical properties, in various types of engineering machinery parts, precision casting of large-scale use. 1) Mn low-alloy steel With manganese as the main alloying elements, and silicon, molybden...
Carbon Steel Casting
A country that has adopted the carbon content of steel is used as the standard classification. Table 1 lists the national standards of carbon steel casting, on the steel grades, chemical composition and mechanical performance requirements, grades of “ZG” said Steel, followed by numbers indicate the weight fraction of carbon steel, the nominal value, to the very few that. Impurities in steel casting according to their level of phosphorus and sulfur content and is divided into three le...
three type of intensity for investment casting shell
Shell quality should meet the strength, permeability, thermal expansion, thermal shock, thermal chemical stability, thermal conductivity, shelling and other performance requirements. Strength Shell strength is the most important and basic performance, the difference in the investment casting process stage the strength of three different indicators, namely temperature strength, high temperature strength, residual strength. 1. Temperature strength Smooth shell temperature strength wet strength mea...
Sand Casting Brief
According to statistics by sand casting priority Casting production in all, 60 ~ 70% of sand casting is produced, and about 70% of which is clay sand production. Mainly due to sand casting and low cost compared to other casting methods, production process is simple, short production cycle. So as the car engine cylinder block, cylinder head, crankshaft, etc. are used for green sand casting process production. When the wet type can not meet the requirements and then consider the use of clay, sand ...
