Types of silver casting machines

A silver casting machine is a piece of equipment used for pouring and solidifying molten silver into specific molds or shapes. There are four popular types of silver casting machines based on the casting method: vacuum casting machines, centrifugal casting machines, pressure casting machines, and atomic casting machines.

• Vacuum casting machine for silver:

  The vacuum silver casting machine is the most common type. It combines metal pouring and vacuuming into a single unit. The pour part is usually a gooseneck-type pour with a clamp on it for positioning. The casting is done with the aid of a vacuum chamber that extracts air bubbles from molten metal to create jewelry objects with excellent surface detail. These machines are available in tabletop or floor-model sizes.

• Centrifugal silver casting machine:

  In a centrifugal silver casting machine, a rotating internal chamber forces molten silver into the jewelry mold. The force from the rotation of the machine helps the molten silver fill the mold completely and evenly. Utilizing this method of casting helps create detailed and accurate replicas of desired jewelry designs. The models are typically made of low melting point alloys like brass or bronze, and the cavity is hot to allow the metal to solidify quickly. Some common features of a centrifugal casting machine include a dust-proof cover, pressure gauges, male and female spindle threads, and 40mm quick disassembly functions.

  A well-centrifugal casting machine will have different spindle sizes for customers to choose from. The alternative would be to buy the spindles only, saving money and time in the long run.

• Pressure casting machine for silver:

  With the aid of high pressure and temperature, a pressure casting silver machine produces jewelry pieces from molten metal. This machine builds up pressure to force the molten silver metal into molds with extreme accuracy, thereby creating jewelry pieces with excellent detail precision. Pressures in the machine can be anywhere from 12 to 15 bar, and the silver casting machines can be pneumatic or hydraulic in terms of function. Some pressure casting machines come with a digital screen and are fully automated.

• Atlas silver machine casting:

  A metal is poured into a mold where a vacuum has formed. This form of casting is known as atomic or investment casting. It is one of the most accurate techniques because of the precision of the vacuum. It can replicate very small, complicated details, including all the minutiae internally and externally, which other types of castings cannot do. This type of casting machine is also popular because it is a modelless type of casting. This means that the mold used for atomic casting requires no initial model to create the mold, which helps to save a substantial amount of time.
