Rapid prototyping technology is constantly changing and brings industry innovation with new and advanced concepts. The use of rapid prototyping, especially 3D printing, has never been restricted, and has occupied various categories in the market, such as clothing, cars, art and crafts, etc. One of the main terms of the rapid prototyping industry is vacuum casting. Many industries have introduced the concept of vacuum casting services into their businesses to provide special benefits to people around the world. The discussion showed the importance of services, so it’s time to understand the details, such as features, advantages, disadvantages, and so on.
What is the vacuum casting process?
This method treats a rubber-like material called an elastomer and then uses a vacuum to cast it into a mold. The liquid material is transformed into a solid structure after several steps.
This process, also known as thermoforming, is a manufacturing process in which a plastic sheet is preheated until it becomes soft and soft.
Second, the preheated sheet is in contact with the mold, and the vacuum source is kept open. The sheet is vacuumed onto a mold to form a defined shape.
Third, once cooled, the liquid has the shape of a mold. The vacuum casting service is completed by die cutting of the mold.
The process takes the shortest time to complete, and each part of the mold has an easy, smooth surface treatment and requires minimal trimming. Perfect shape is the desired result that people want to have after a few steps of service.
Advantages of vacuum casting services:
Helps make larger parts
Traditionally, the old technology in 3D printing can only handle smaller designs, but vacuum casting is used where large workpieces are needed, and can easily meet people’s needs.
Fast production time
Prototype technology used to take days to produce results, but in contrast, vacuum casting services take up to four weeks. If a lot of labor and machinery is needed, it can be done in 2 to 5 days.
Low start-up and production costs
This process is good for startups that start with small amounts of production. This process is suitable for small-scale production, such as large orders in any other process.
Disadvantages of vacuum casting services:
Difficult to obtain complex functions
The process of customizing to customer requirements is well known, but if there are any complex functions, additional tools such as pressure forming are required. This process requires expensive equipment.
Poor mold maintenance will affect performance
Companies that provide vacuum casting services need regular mold maintenance to ensure the process is successful. After continuous use of the same mold, it starts to leave marks, which means that it must be cleaned immediately.
The problem of hollow casting
As already discussed, this method involves casting molded parts, but in the case of hollow parts, this becomes challenging. So far, there has been no scientific development to solve these problems.
