Heat seal is a popular method for safeguarding products from spoilage and contamination. It involves fusing together two layers of packaging materials with high-intensity heat creating a strong durable and impenetrable barrier that protects products from air and other contaminants. Like all machinery a heat seal machine can experience wear and tear over time leading to malfunctions that compromise product integrity and productivity. This is why regular inspections and prompt repairs with the right replacement parts are essential.
Heat Seal Machine Parts
Various parts of your heat seal replacement parts are subject to daily wear and tear including the heating element, Teflon coated bands or belts as well as temperature control units and sensors. These parts are constantly exposed to high temperatures during the sealing process which can lead to gradual degradation and necessitate a replacement in order to guarantee consistent high quality seals each and every time.
It is a common misconception that heat seal machines are difficult to repair due to their complicated components but in reality many of the parts needed are quite simple to replace. All you need is the right heat seal machine parts and a bit of know-how to keep your packaging machine up and running.
Heat Seal Elements
Often referred to as a “hot rod” the heating element in your heat sealer is responsible for melting and sealing the material being packaged. Over time the heating element wire can become damaged resulting in poor sealing and high energy bills. The best way to prevent this from happening is by regularly checking the condition of the element and replacing it before it burns through the PPFE fabric cover.
This is an important step to take as a burned hole in the cover will cause the material being sealed to stick to it and shorten the element wire’s life. Often the cover will begin to discolor from tan to black along the area that touches the element wire.
Another common issue with heat sealers is a malfunctioning timer unit that doesn’t turn on when the movable arm is pulled down. This can be caused by a worn out or defective microswitch. The microswitch is the part that completes the electrical circuit when the movable arm is pulled down to start the sealing cycle. In order to check if the switch is in good condition it is best to remove the bottom cover of the heat sealer.
