Advantages and disadvantages of low pressure casting
The development of the casting field is obvious to all, and the casting methods have become diversified. Among the many casting methods, there is a low pressure casting, which is more important and has more advantages. Low pressure casting includes investment casting, precision casting, lost wax cating and sand casting. But each has its own characteristics. It is difficult for one method to be perfect, so low-pressure casting also has defects in some aspects. Shenzhen SCZY Technology Co., Ltd will introduce some advantages and disadvantages
Common plastic stypes for plastic precision machining
1. POM, also known as polyoxymethylene or Delrin, is one of the easiest and most commonly used plastic materials for plastic precision machining. Although it is easier to process than ABS, high-strength engineering plastics are slightly more expensive as raw materials, which affects its overall processing cost. POM is known for its excellent wear resistance, low friction, strength and dimensional stability. These material properties lead to the use of POM in various end-
The Housing Making Process of lost wax casting
Our SCZY LTD is one of the leading manufactuers of investment casting parts also we call it lost wax casting parts in China. Today we want to share the housing making process of the lost wax casting processing. Let's discuss it more. The main procedures and processes in the housing making process are: 1) Degreasing and degreasing of modules When using wax-based molding materials to make investment patterns, in order to improve the ability of the paint to wet the surface of the module, the oil on the surface of the module needs to be removed. 2) Apply pai
The common pouring methods of investment casting process
Now I think we have talked quite a lot of the procedures of investment casting parts produciton. Today we want to talk about the pouring methods commonly used in investment casting production. Do you know about it? 1) There are the following methods for hot gravity pouring. This is the most widely used form of casting, that is, after the shell is taken out of the roasting furnace, it is poured at high temperature. At this time, the metal cools slowly in the mold shell and can fill the mold with high fluidity, so the casting can well replicate the shape of the cavity and improve t
Dear friends, Christmas is coming soon, we would like to extend to you our sincere holiday greetings and best wishes in this special Christmas season. Wish you a happy New Year. May all of you be blessed with happiness and health.

The process characteristics for steel casting
Steel casting parts often have various casting defects such as blisters, pores, cracks, shrinkage porosity, shrinkage cavities and inclusions, and production control is difficult, especially for sand-cast alloy steel castings. The melting point of cast steel is high, the molten steel is easy to oxidize, the fluidity of molten steel is poor, and the shrinkage is large. The volume shrinkage rate is 10-14%, and the linear shrinkage rate is 1.8-2.5%. In order to prevent defec
Investment Casting Process Steps at China Casting Company
The following steps are what we follow to produce investment parts with complex geometries and intricate details. 1. Create wax pattern: A pattern that replicates the finished part geometry is made using one of two primary methods: A. Build a wax injection die B. 3D print pattern
The Advantage and Application of traditional lost was casting processing
SCZY LTD is specialized in lost wax casting for different materials, normally we do Stainless Steel Casting, carbon steel casting, brass casting, as well as other special alloy casting, etc . For lost wax casting, we also call it investment casting, which is a production process in ancient China. In modern times, it is still the method used to bring out the finest details in met
The four process methods of stainless steel investment casting
Stainless steel precision casting mainly includes the wall thickness, shape and weight of castings. Do you know what are the process methods of stainless steel precision casting? 1. The characteristics of sand precision casting, due to the favorable conditions such as internal sand core, loose block pattern, gasification mold and other special molding techniques, it can produce castings with comp
The difference between stainless steel castings and stainless steel forgings
1. Stainless steel castings have good wear resistance and shock absorption function, because graphite in cast iron is good for lubrication and oil storage, so it has good wear resistance. Also due to the presence of graphite, gray cast iron has better damping properties than steel.SCZY company introduced that stainless steel castings have good process performance. Because gray cast iron has high carbon content and is close to eutectic composition, it has relatively low melting point, good fluidity and small shrinkage rate, so it is suitable
The purpose and function of impregnation treatment of aluminum casting parts
Pores are a common phenomenon in the production process of aluminum casting parts, especially in the manufacturing process of die casting parts and powder metallurgy, due to the residual pores, crystal shrinkage and other reasons, a large number of micropores, sand holes, cracks, etc. are inevitably formed, and microporous penetration Leakage will bring hidden dangers to the use of machinery and equipment. Even if it is used for applications without pres
Selection of pouring position for precision investment casting parts

Removal of crystallisation from aluminium casting parts, temperature and quality of return material
In the process of manufacturing aluminum casting parts, it is necessary to effectively prevent the generation of pores. In the process of manufacturing, it is necessary to take effective measures to reduce the moisture of its raw materials as much as possible. In the process of processing aluminum castings, it is necessary to choose a reasonable investment casting process. Effectively strengthen its smelting quality management. All the raw materials used in aluminum alloy casti
Characteristics of hardware precision machined industry
1. Sheet metal machining Sheet metal mold making is fast and cheap, with very short lead times. Sheet metal can be a good alternative to plastic injection mold for internal structural components, as it provides greater flexibility early in the design process, when changes may still occur or the forecast for the product is unclear. 2. CNC Machining
