Vacuum Casting Machine | Alex Machine

Looking for the most cost efficient method of making prototypes for your jewelry? Look no further than vacuum casting, a casting system that’s been making waves across the industry.

What makes vacuum casting fascinating is that it requires the exact temperatures for curing the material. For example, if you are using resin, you will need a temperature of 30 degrees Celsius for 5 minutes of vacuum pressure time – this reduces the chances of shrinkage occurring. The mould temperature must be 60 degrees Celsius.

Vacuum casting works in a very similar way to the process of using a silicone mould.

The technique of vacuum casting by utilizing silicone moulds was discovered in Germany around 1960.

What is a vacuum casting machine?

As the name implies, a vacuum casting machine uses a vacuum to cast a material. It is often the go-to option in situations where air entrapment can cause issues with the mould.

A vacuum casting machine is also great if there is a need for undercuts and other intricate details or if there is a requirement to use reinforced wire or fibre as the material for casting.

In some situations, the process used by a vacuum casting machine is called thermoforming – this is due to the fact that the process used by a vacuum casting machine involves preheating the plastic sheets. These materials are preheated in the vacuum casting machine till it is pliable and soft.

Are vacuum casting machines fast?

A vacuum casting machine is very fast and will help deliver results in a much shorter time frame than is possible with other casting machines or techniques. As a rough guide, processing 50 final prototypes with a vacuum casting machine should take you between 7 to 10 days.

This is a huge asset for craftsmen dealing with a range of products, especially under tough deadlines as is often the case in a jeweller's workshop.

Where to buy vacuum casting machine

With the wide range of choices, it can sometimes be difficult to find a reliable supplier for casting machines. However, purchasing from Alex Makina promises a reliable modern vacuum casting machine at highly competitive prices for anyone looking to make a purchase.

Benefits of jewellery vacuum casting machine

A jewellery vacuum casting machine has many benefits that make it well suited for casting.

Jewelers will appreciate the fine detailing and high precision afforded by the device, especially if you were to use silicone as the mould. Without a doubt, the final mould will look like an exact replica of the original product.

Another reason that these machines are well recommended is due to the guaranteed quality. Moreover, the ability to use resin enables you to make the right decision when it comes to choosing the right material.

This affords a wider variety of choice regarding the rigidity, hardness, and flexibility you want to see in your product. It, of course, has a huge effect on the final appearance of the product.

What materials can be used in the vacuum casting machine for jewelry?

The high flexibility of rubber makes it suited for seals and gaskets. It is also easily accessible and inexpensive.

ABS has high rigidity and strength so does glass filled nylon and polyamide.

High density propylene and propylene have a high elasticity. For resistance towards shock and temperature fluctuations, look towards Polycarbonate. It has a good-looking translucent colour to boot.

Is a jewelry vacuum casting machine safe?

A jewelry vacuum casting machine is one of the safest casting tools you can use. Vacuum casting jewelry has virtually no downsides to it!

Vacuum casting supplies

As I mentioned above, a jeweler has a wider range of vacuum casting supplies to choose from if he or she is using vacuum casting. This can help meet a jeweler’s specific requirements in areas like physical, thermal or mechanical properties.

 Uses of vacuum casting equipment

Vacuum casting equipment is used for bespoke products, in the automotive industry, product design, and the medical industry to name a few.

Can you cast gold in a gold vacuum casting machine?

You can find speciality gold vacuum casting machines that can cast gold easily.

Price of a gold casting machine for jewellery

The price of a gold casting machine for jewelry depends solely upon your requirements.

Vacuum casting machine price

The price of a vacuum casting machine price varies too much to give an exact figure but it’s not difficult to find great machines at budget prices.

How does a vacuum casting machine work?

Often, the first question when it comes to a vacuum casting machine is ‘how does a vacuum casting machine work?’

Well, here’s how. Vacuum, vibration and heat are used to melt sand and plastic films over a pattern, helping to create a mold of the component you want duplicated. Suction by the vacuum holds the mold in the right position till all the metal has been cured.
