1. Consider future closure flexibility of the Chemical Can Making Machine. Like any other packaging machine, try to anticipate future needs. Capping machines may need to be able to deal with a variety of different types of closures over time. Over the years, cap designs and applications have become increasingly complex: For example, spray-through caps must be oriented with the graphics on the container.

2. Rotary capper considerations. When looking at rotary machines, examine the number of heads and infeed method (starwheels or screws). A key element to look at is how the cap is applied. Servo-driven chuck applications permit easy changeover to different closure styles. Closure pickup is critical, as is chuck handling. Look at the capper’s centering mechanism and any anti-rotation devices to ensure proper closure placement.

3. The need for speed. Think about how many heads are required to achieve your current line speed, and make sure you have the ability to add heads later for higher-speed applications.

4. Examine container handling and stabilizing. For some lighter-weight plastic bottles, you’ll need to look at the machine to assess how well it holds the container tightly in place during the capping application and torquing to assure a good seal, especially for food products.
