Types of Spin Cast Machines

With the advancement of technology, various types of machines for spin casting have been invented and are now in use. These machines help to produce metal products as per the needs and specifications of the customers.

• Conventional Spin Casting Machines: These machines usually use a centrifugal force for casting various kinds of metal materials. Such materials may include zinc, aluminium, and many others. The machine is fixed at the center of a casting area. The metal material is poured into the machine through a manual or automatic gating system. Then, the machine is rotated at high speed. The spinning motion of the machine forces the material into the mold from which the desired product is formed. Products that can be made by this kind of spin machine include; jewelry, automotive parts, hardware, and figurines, to mention but a few.
• Vertical Spin Casting Machines: As the name goes, these machines are vertically oriented. They have a vertical rotation axis. The machines are widely used for producing precision parts and complex shapes. Generally, the vertical casting machine is capable of producing high-quality parts with fine details. Also, the parts are produced at fast speeds and at a low cost. The vertical machines make use of gravity and centrifugal force for the casting of materials into the mold.
• Automatic Spin Casting Machines: These machines come with an automated spin casting system. This helps to increase the casting precision of products made. With the automation of the machine, there is a consistent quality of product, and the efficiency is also high. The automation system of the machine may include computer numerical control (CNC) or various other programmable logic controls (PLC).
• Horizontal Spin Casting Machines: Similar to the vertical casting machines, these horizontal ones are also opposites. As the name implies, the machines are horizontally oriented with a horizontal axis of rotation. They are mostly used in the production of larger parts. Moreover, the machines are excellent for high-volume production. The speed at which this machine works is very fast, and it is cost-effective.

Specifications and Maintenance of a Spin Cast Machine

Specifications

• Capacity

  These spin casting machines can have make-capacity ranging from small to large amounts per hour. It is determined by the amount of time required to cast each one and ease of machine control. Smaller machines may manufacture 10 to 20 pieces per hour while larger industrial models, with greater skill levels at handling the machine, could produce 50 to 100 per hour or more.

• Die Size

  Spin casting dies normally have a range from 2 inches to 12 inches (5 to 30 cm) in diameter. Larger die sizes allow for the production of bigger pieces, but they also cause the machine to become larger in size.

• Materials Compatibility

  Some machines have very limited capabilities and are only able to work with some metals. Others can handle a large variety of alloys including zinc, aluminum, brass, bronze, and even some plastic polymers. Details must be found to work out what material the machine can handle.

• Power Source

  More advanced spin casting machines are electrically driven, while spin casting machines without much technology are human operated, that is, through foot pedal control. Partially automated machines may use pneumatic pressure to spin the casting. Pneumatic power sources require compressed air systems that may use air hoses and other equipment. Fully automated machines use electricity. Advanced electrically powered machines may have variable speed controls and other ways to control things precisely. Machines that are fully automatic will produce at least 10 times greater production capacity than those that are not fully automatic.

Maintenance

• Regular Cleaning

  It is important to get rid of any metal residue, lubricant build-up, or debris as quickly as possible after each operation, to keep the machine in tip-top and cast its best condition. Dedicated cleaning brushes, solvents, and products are often provided to help maintain the machine's quality over the longer term.

• Lubrication

  Any moving parts should be oiled regularly according to instructions and parts diagrams, including bearings, chains, and slides, to ensure smooth operation.

• Die Maintenance

  It is necessary to clean the casting dies thoroughly after each use and to lubricate them as appropriate to avoid any casting-related issues that could arise in the future, such as jamming or uneven wear.

• Electrical and Pneumatic Checks

  For the more automated and longer-production machines, it's required to check the electrical connections, as well as the air hoses and fittings, and to inspect the variable speed drive to ensure everything is in good working order and nothing is broken.
