Quick guide: components for industrial packaging machines

clock 15 minutes | 04 Feb 2021

Packaging machinery

The quality of the components you choose will play an important part in the life of your packaging equipment.

Your packaging machine parts might rely on everything from cable ties and PCB mounting hardware to clamping levers and screw-on rubber bumper feet. Choose your components wisely and you can deliver a semi-automated or automated packaging machine that performs for years.

This guide is designed to help you make those choices. We’ll focus on three types of packaging machines, but most of the components shown for each can be used on all machines, such as can packing machines, cardboard box packing machines, carton wrapping machines, and sheet packing machines.

Strapping machine

Strapping machines

Sometimes called banding strapping machines, they tension, seal and cut the strapping in one motion. Your design will depend on the strapping demand. Whether your application will be a pallet strapping machine, box strapping machine or another type, consider the recommendations below, which are ideal for semi-automatic or automatic strapping machines.

Where relevant, the components you use should not only help the machine’s performance but contribute to health and safety, so consider insert glides and recessed handles.

Your strapping machine also needs protecting. Use caps and plugs to protect critical profiles from damage during handling and transportation. You can also get a professional finish by using high-temperature masking for holes and contact points with easy-to-fit caps and plugs.
