Casting then Machining
The die-casting process is mainly used to produce metal alloy products, electronic products shells, car parts and other products. Die casting machine is a commonly used casting process that can produce complex shapes, high -strength, and high -precision metal products. It uses the melting metal in the die -casting mold to fill the mold of an object under high pressure to form an object.
The die -casting machine is divided into two types: the cast pressure and the high -pressure die -casting machine according to the casting pressure. The normal pressure die -casting machine is suitable for the production of large aluminum alloy parts. The high -pressure die -casting machine can produce high -strength, high -density zinc, aluminum, magnesium and other different materials. Components.
The die -casting machine is a kind of equipment suitable for mass production. It is simple in operation and high production efficiency. It can produce small parts and large industrial parts, which can produce extensive application prospects.
Is It Always Necessary to Machine a Part after Casting?
Casting has various types such as sand casting, melting mold casting, die casting, gravity casting, and extrusion casting. Due to the existence of pouring, portrait, and mouth, each casting of each of these two methods has some additional parts.
Therefore, in order to get rid of these extra parts, it is always necessary to process parts after casting. Casting is always incomplete without processing. This is why different types of castings have different processing margins.
What are the benefits of processing after casting?
There are many benefits of machine processing and casting. For example:
Make parts accurately. The usual casting process, such as die casting and sand casting, is not enough to create precision parts. No matter how good the casting environment and setting are, there will always be some additional materials to the parts. Manufacturers can make parts more accurate through mechanical processing and remove excess metals.
Make complex parts. Some parts are complicated, and it is impossible to design and make molds according to design. In this case, mechanical processing helps to achieve complex shapes. For example, many castings have holes in complex parts. Drilling or drilling is the only choice for these holes.
How is Machined Casting better than Only Casting or Machining?
Any form of casting process has high production efficiency. A large number of parts can be made at the lowest cost in a considerable short time. However, the accuracy and precision of the parts cannot be provided by casting alone.
Unprocessed castings will be attached to the casting. In addition, sometimes the division line may form a flash. Therefore, extra post -treatment, such as sawing, trimming or processing.
On the other hand, it can provide very accurate parts through CNC processing. However, CNC processing is a very time -consuming and expensive process. Therefore, mechanical processing is not suitable for mass production parts.
However, the processing and casting process of machinery combines the advantages of casting and CNC processing. By processing casting, manufacturers can enjoy the high -speed and economic benefits of die casting, and can also enjoy the high accuracy of CNC processing.
What are the limitations of machined casting?
Some restrictions on the processing casting of the machine are:
Only trained professionals can handle, control and operate these machines.
Maintaining these machines regularly requires fees.
The purchase and installation of CNC drilling, milling, and car are expensive.
Although setting and maintaining machines require some initial and conventional costs, in the long run, it does save overall production time and cost.
The process of cutting or removing materials from castings to make part dimensions more accurate is called machining casting process. Post casting machining also helps to remove unnecessary parts from the casting.
Maintaining appropriate tolerances in complex castings is difficult, and machined castings can help maintain this. This process is carried out after heat treatment, before surface treatment such as painting or anodizing.
Modern technology uses computer numerical control or CNC machine tools to process castings. There are various types of machining and casting processes, such as:
The broaching process uses cutting tools with teeth to cut different shapes from the parts, while grinding uses grinding wheels as cutting tools, which have small abrasive particles that aid in cutting.
