SA™ Semi-Automatic
Bottle Capping Machine

The ST™ Capping Head

Fit your SA™ benchtop capping machine with a 316 stainless steel capping head. 316 Stainless steel is the material of choice for use in laboratory, pharmaceutical, sanitary and sterile packaging environments because it is easy to clean, resistant to corrosion, and is chemically resistant to the cleaning agents commonly used in these environments.

In addition to their 316 stainless steel construction, ST™ capping heads include other features that make them ideal for use in clean settings. The internal components of an ST™ capping head are lubricated with NSF-H1 Food Grade Certified lubricants. The Kinex Exhaust Capture System™ is integrated into the design of every ST™ capping head. As an option, the ST™ capping head can be built with one of our oil free pneumatic motors.

Oil Free Pneumatic Motors

Equip your SA™ Capping Machine with an optional oil free pneumatic motor. Just as the name suggests, our oil free pneumatic motors do not require lubrication. An oil free pneumatic motor can be installed in an ST™ capping head and a standard SA™ capping head.

Standard pneumatic motors cannot be used in many clean environments because they expel a tiny amount of lubrication in their exhaust. Although the amount of oil they expel is so minimal that it is completely imperceptible, it is still not suitable for a clean environment. Since our oil free motors require no lubrication, the exhaust air exiting the machine is as clean as the compressed air going into it.

Exhaust Capture System™

The Exhaust Capture System™ is built into the ST™ capping head and can be added as an option to the standard SA™ capping head.

The Exhaust Capture System™ is an enclosure built into the capping motor that captures the exhaust air expelled by the capping motor and channels it directly into an air hose. The exhaust air then travels through the air hose to where it can be expelled in a location that will not adversely affect the clean environment.

Oil Free Pneumatic Motor with Exhaust Capture™

Combining these features will ensure that the air in your clean room is contaminant free and the air flow in your clean room is undisturbed.

Machined Chucks

The urethane or white rubber inserts within a standard chuck will wear slowly over time and can occasionally leave very small amounts of urethane or white rubber particles on the caps they tighten. These particles may not be allowed in certain clean, sterile or controlled environments.

Machined chucks are ideal for clean environments since they do not wear and do not create particles. Machined chucks are custom made to fit the rib pattern of a particular cap. They fit the cap in the same way as a socket fits a nut. Machined chucks also improve torque accuracy and never have to be replaced.

Cap Retaining Machined Chucks

A cap retaining chuck is a machined chuck that is designed with additional features that allow it to grasp and retain the cap it is designed to work with. Below are a couple of examples of applications in which they are useful.

• De-cap and Re-cap Operations
  When decapping a container with a cap retaining chuck, the cap remains in the chuck after it has been removed from the container. This makes it ideal for use when you want to reapply the cap that has been removed.
• Pick & Place Operations
  Cap retaining chucks can be used to pick up a cap, hold it, and then tighten it onto a container. For this reason, they are ideal for use with automated capping machines and automated robotic capping systems.
