How Much Do You Know About The Process -- Vacuum Casting

What is Vacuum Casting

Vacuum casting is a manufacturing process used to create high-quality, detailed, and dimensionally accurate replicas or prototypes of original models. It involves the use of a vacuum to draw liquid material into a mold, which then hardens to form the desired part. This process is often used in industries such as automotive, aerospace, medical, and consumer products for rapid prototyping machining services and low-volume production.

Why Vacuum Casting

In our daily lives, we often apply plastic products, in general products, that use more thermoplastics, this plastic in industrial production, generally with thermoforming, can be shaped. However, in our product design, the appearance of some products needs to be heat and corrosion-resistant, these products need to use plastic and should have good thermosetting, the designer in the selection of materials, we to take into account the way the product is formed will be used in the vacuum casting process. 

Vacuum Casting Mainly Usage

Vacuum casting is mainly used for prototype manufacturing, single-piece production, and small-batch production, and can replicate almost all the properties of the injection molding process. It is mainly used to mold two-component polyurethanes (PUR), which are widely used in different grades, colors, and hardnesses. Flexible silicone molds are machined directly from the mold and then vacuum cast to reproduce the product with properties very similar to those of mass-produced products. A full-color range is available. Can be as flexible and elastic as a thermoplastic elastomer (TPE) or as hard as acrylonitrile-butadiene-styrene (ABS). 

Typical Applications for Vacuum Casting

Vacuum casting is widely used in the automotive, consumer electronics, consumer goods, and sports equipment industries. In addition to prototypes, vacuum casting is also used for injection molding of small quantities where expensive molds are not intended. In the automotive industry, applications include the production of various tubes, water tanks, air filter housings, radiator parts, lamp shades, chips, gears, and moving hinges. Consumer electronics applications include the manufacture of keyboards and housings for cell phones, televisions, cameras, players, audio systems, and computers.
