Benefits of Vacuum Casting Machining for Rapid Prototypes
Vacuum casting is a rapid and effective method of making prototypes. It delivers high-quality products. Vacuum casting can be used to create end products in low numbers. This procedure normally uses silicon elastomer as the raw material. Two components of polyurethane are also used. This is because the compound has a malleable texture. In vacuum casting, a vacuum force draws molten elastomer into a silicone mold. After that, the elastomer is cooled down so as to create a final product. In this way, vacuum casting can be used to make copies of small plastic parts in low volumes. This process has a very quick rate of production. Read on to discover more about Vacuum Casting Machining.
Three processes of vacuum casting machining
-
Creating the master parts
First of all, the vacuum casting needs to create master parts, which need to keep durable, good construction and precision. Usually, we use CNC machining, 3D printing to make them as these processes are fast and cheaper. After the master parts completed, we need to inspect its feature, dimension, assemble testing and appearance to ensure the parts as we need.
-
Establishing the casting molds
We need to make the casting box to put the master part and filled with liquid silicon, Then put whole silicon mold into vacuum casting machine for oven some hours, till the silicon mold solidified and cut the mold along the scheduled seam line, then take out of master parts. Let silicon mold leaves an empty cavity which is exactly the same as the product construction.
We need to reseal the silicon mold, and inject the liquid resin as expected into the silicon mold and put the mold into the vacuum machines. Vaccum machines purposed to ensure there is any air in the mold, then oven some hours till liquid resin solidified. Finally, we open the silicon mold based on last scheduled seam line, You will see a great element completed, then we need to inspect and make secondary finishing process to decorate products.
Advantages of vacuum casting machining.
-
Good quality and appearance
Vacuum cast items have a higher level of quality when compared with 3D printing products. The vacuum casting procedure preserves the dimensions of the final product as indicated in the design. Thus, models made using vacuum casting can be implemented in function or fit testing. They are also ideal for marketing or as finished products for show and testing.
Vacuum casting machining gives results very quickly. The process works rapidly due to the procedures which are implemented. They include mammoth stereolithography, silicone molding and polyurethane pouring. The procedure also uses curing ovens that produce solid products in record time. As such, vacuum casting is a fast method of creating products.

Various machining purposed
Vacuum casting is a versatile procedure. It can be used to create a wide range of products designs. Their range from micro component to more complex parts such as inside construction and transparent product even our CNC machining and 3D printing can’t be machining. The procedure can be used to create items of varying dimensions. As such, it is versatile and applicable in various industries.
When compared with other industrial processes, vacuum casting is more cost-effectiveness. That’s because it is not labor intensive. The components which are used in vacuum casting are also easily accessible. It also does not require large amounts of machine equipment than our CNC machining, 3D printing and injection mold. Furthermore, it does not ask any tools cost and facilities cost. Due to these reasons, vacuum casting is very affordable.
For many products, designers want to add more decoration like coating, painting and silk-screen. Vacuum casting is very easy in dealing. It is quick, accurate and effective. Hence, this process is ideal for your rapid prototypes and low-volume manufacturing needs.
Your product designs are suitable Vacuum Casting Machining?
Are you searching for a method to create strategic components? If yes, vacuum casting is for you. This is also the process to use if you would like to create prototypes in a short time. Vacuum casting is also good if you would like to create low volumes of products. It is a versatile, capable procedure which you can use for various production purposes today.
One of the procedures that are used for prototyping or rapid production is vacuum casting machining. It is a quick, accurate and cost-effective way to create rapid prototypes. If you would like to create components, part, products or even test objects, vacuum casting is the way to choices.
