Can seamers play a critical role in the manufacturing process. For this reason, if your unit starts to produce low quality seams, getting to the bottom of the problem becomes a priority. Fortunately, there are a number of practical reasons why your seams could be failing. Here are just two of them.
Over Tightening Of The Seam
A common and costly issue some owners face is a weak seam. In many instances, they've seemingly done everything right, but the finished result is a poor seam that is prone to leaking. This type of problem is often a chain reaction of issues sparked by over tightening. There is a fairly common misconception that when laying out the seam – tighter is always better. The opposite is typically the case.
When the seam is too tight during production, this causes spring back to occur, which will actually cause the seam to open up very wide. When the seam expands, this in turn causes the chuck or rolls to become misaligned. Dealing with this type of issue doesn't just increase production time, it can also cause a great deal in the form of wasted materials. Avoid over tightening the seam to avoid this type of problem. Understand that proper positioning is more important than over tightening.
Broken Ball Bearing
Another reason for a poor seam could be a broken ball bearing. Seamers generally have ball bearings inside them that keep the moving parts in place and allow them to rotate smoothly and without friction. In high-quality units, the bearings are generally made from ceramic, as it's more durable and less likely to break. In low-end models, less expensive materials are often used, making breakage a more common problem.
The problem is that when a bearing breaks, it no longer stays in place. Instead, it's fragmented pieces move about. During the seaming process, these loose fragments can get in the way and prevent the seam from forming correctly. Even if the seam forms the right way, they can also get in the way and cause imperfections in the seam, which opens the door for leaks. If you're noticing imperfections open the unit and check for ball bearing fragments.
The quality of the seams you produce is a vital part of your business. Poor seams put a damper on your reputation and yield low quality products. If there is an issue, make sure you are getting to the bottom of it as quickly as possible. For more tips, contact a local can seamer supplier or repair company.
