What is vacuum casting process?

Vacuum Casting is a copying technique used for the production of small series of functional plastic parts. Using two-component polyurethanes and silicone molds, Vacuum Casting is known for its fast production of high-quality prototypes or end-use products. Silicone molding results in high-quality parts comparable to injection-molded components. This makes vacuum casted models especially suitable for fit and function testing, marketing purposes or a series of final parts in limited quantities.

Vacuum Casting also lends itself well to a variety of finishing degrees, and we can match the finish you need for your parts. Vacuum casting is a highly versatile technology capable of producing parts in a range of polyurethane (PU) resins and cast nylon, create, replicate and replace engineering polymers for prototypes and end use parts. 

The manufacturing technique is ideally suited to low volume batch production when injection moulding is not cost beneficial; typically a single mould can be used to produce up to 15-20 parts before re-tooling is required. So we can got high quality prototype and save a lot cost.

Various types of codes of the PU materials are on hand in the process of vacuum casting with the help of which different types of mechanical features of POM, ABS, PC and many more can be attained easily. This approach delivers economic benefits for small batches of parts, and of course the castings produced can be in the required colour.  and carry the desired surface finish like gloss, matt etc. direct from the tool without the need for post finishing operations.

The process of vacuum casting is the perfect choice to support market research, exhibitions, photography for advertising and packaging, and marketing as it can deliver production injection moulded like components. 

How to make soft rubber/silicone prototype?

The main component of silica gel is silica, chemically stable and does not burn. In daily life, more and more common, we can create a variety of colors of various hardness silicone prototype, the number of flexible, 1 ~ 1000 can be customized.

Advantages of silicone prototype and low volume production Vacuum casting process

Soft, comfortable and colorful: Silicone materials produced by the product's soft feel is good, according to the needs of customers, deployment of different colors.

Flexibility for quick delivery: The mold is simple, the processing speed is fast, and the reproducibility is strong.

High temperature range: High temperature resistant temperature range -40 to 230 degrees Celsius, can be used in microwave ovens and ovens. Low temperature silicone still has good elasticity at -60 degrees to -70 degrees.

Long life and non-toxic environment: The chemical properties of the silicone material are very stable, and the manufactured products have a longer life than other materials. They do not contain toxic substances and are environmentally friendly and are in line with sustainable development strategies.

What used for silicone prototype, silicon Vacuum Molding product, silicone low volume production?

1.silicone products for electronic products, beauty equipment, signal receivers, remote controls, toys, silicone buttons.

2.can be used to make durable forming gasket, electronic parts of the packaging materials, automotive electronics accessories maintenance materials.

3.can be used for baby products, maternal and child supplies, baby bottles, bottle protection sleeve.

4.can be used for kitchen products, kitchen utensils production and related auxiliary kitchenware products

5.can be used for medical equipment accessories, because silica gel is colorless, odorless, non-toxic and other characteristics are widely used in the medical industry
