​Guide To Multi-Tip Tooling Equipment

Print
2 September 2016 No comments

The multi tooling equipment has long been used in the pharmaceutical industry and has been in existence for more than 150 years. During the start of the tablet compression industry, companies use single station presses during production and these were outfitted with multi-tipto improve and increase production volume. Aside from volume output, multi-tip tooling also reduces energy, labour, maintenance and requirement for expansion of production areas. In the late 1800’s, a new tooling, the 16-station rotary tablet press was introduced, reducing the need for the single station and multi-tip tooling.

Aside from the pharmaceutical industry, other industries such as the confectionery, the industrial and food industries saw the advantage of the device and they have been using themulti-tip tooling.

Multi-tip Tooling

The multi-tip tooling is available in two different configurations. The first one is the assembly or the multi-piece and the other one is the solid. In choosing the configuration type, it is essential that one consider the following:

  • Tablet size to produce
  • The tool type
  • Number of tips per punch
  • Tool handling practices
  • Proper maintenance
  • Inspection protocol

To make it easier to choose the configuration type, tablet manufacturers can communicate with their tooling vendor on the device that would best fit their needs. The tooling vendor has guidelines that would be helpful for tablet manufacturers to choose the right tool type.

Assembly Configuration

This configuration type is composed of a punch body, a cap and individual punch tips. One advantage of the assembly type is that one can easily remove the punch tips. Should one of the tips be damaged, one can easily replace it with a new one and continue production. This is a different case should one have a solid assembly, as once any of the tips is damaged, the whole equipment should be replaced which then makes it expensive.

In terms of cleaning and maintaining the assembly, one can disassemble the tips from the body and then reassemble it thereafter. Although reassembling the equipment is quick and easy, one should take care not to damage the mating parts as even a slight nick or debris would result to the tips not aligning. If the tips do not align and production starts, production may fail and damage to the press is possible.

Solid Multi-tip Configuration

Another configuration type, the solid, is becoming quite popular, as it does not require disassembling the tips during cleaning or maintenance making it easier to maintain and the

chance of misalignment non-existent. That said, one disadvantage of the configuration is that it only uses few punch tips in relation to the tablet size.

Investing on Multi-tip Tooling

In order to make a smart and well-informed decision, it is important to check the tooling that you would need. One should check if the presses have turret punch to guide the tip and that the die sockets are in good condition. This is critical as a worn guide or socket can cause premature wear of the tip and even wearing of the head and cam as well as causes binding in the tip guide and die.

A turret inspection kit can help one to check the turret for any signs of wear and it can be used whether one has a single tip or a multiple tip. Constant check and inspection can help one to prevent any premature wear to the tool.

Tablet presses that have tablet rejection system may need validation punches, which are the same with other punches with a slight difference in terms of: a) How it works b) its overall length. The validation punch checks the system by examining the tablets produced in terms of the different features such as the weight, hardness and thickness. Some companies have switched to the multi-tip. That said, others are apprehensive and still checking the effects of the equipment in terms of ejection forces, product flow, compression and tablet rejection system.

Multi-tip tooling has its advantages. A multi-tip with nine tips can produce an estimate of 76,000 pellets/minute as against the 8,500 pellets that a single tip tooling can produce within the same period of time. This is an 800% increase in production capacity for a company, without the added cost.

Companies that are interested in multi-tip tooling should communicate with their tooling vendor to check if their product is qualified. This would certainly increase the volume output without the additional operating cost.
