In manufacturing, products must have proper seals. If a seal fails, then there is a risk of product contamination, leakage, packaging damage, and other issues that would cause customer complaints.
Since sealing issues can come from various causes, coming up with a solution tends to require multiple engineering changes. Here are six different types of engineering solutions that will help you fix your product sealing problems.
1. Improve Seal Design and Material Compatibility
If a seal’s material is mismatched with its product environment, the seal can degrade, crack, or lose flexibility, resulting in diminished sealing effectiveness.
Take into consideration the temperature and chemical environments that your product will be exposed to. When working with a manufacturer like Sur-Seal, you can expect a detailed review of the materials selected. This ensures that the seals are able to withstand the most challenging conditions that may arise during operation.
2. Optimise Compression and Contact Pressure
The seal’s functions rely on appropriate compression. If the compression of the seal is insufficient, an effective seal is not formed. In contrast, too much compression either damages the seal or reduces its life.
This sort of result can be obtained by adjusting the groove depth, modifying the housing design, or altering the compression ratios of the system. Balanced pressure allows the seal to maintain full contact with the surface without excessive wear.
3. Improve Surface Finish and Tolerance Control
Both the surfaces and the seals need to be of high quality in order for them to be able to function properly. Small gaps are created as a result of rough surfaces and inadequate tolerances, which will inevitably result in leaks. A relatively minor breach can have a significant impact on the effectiveness of a seal.
These leaks can be reduced by reducing the amount of machining done and by narrowing the tolerances. When surfaces are smooth and uniform, it is easier for the seal to maintain a barrier.
4. Address Temperature and Environmental Conditions
In response to changes in temperature, contact seals undergo size changes and may become less adjustable. Over the course of time, these alterations may result in vulnerabilities and water leakage.
If seals are supposed to work within a certain temperature range, it’s important to select appropriate materials. The engineering team needs to find a good balance of thermal endurance and high-performance flexibility to prevent seal failure.
5. Improve Assembly and Installation Processes
Even if the seal is foolproof, there is always the possibility that it will fail to hold. It is possible for this to occur if the seal is not properly installed. There are a few different ways that it can be installed: either too far in, too far out, or even broken.
Using the right tools and configurations will help minimise the seal’s failure. The seal will be more dependable if you train your technicians and use quality control.
6. Conduct Thorough Testing and Validation
Testing indicates probable seal breakage locations. Engineers understand seal functionality via empirical testing at varying pressures, temperatures, and moisture levels.
The final stage involves outlining the necessary steps for large-scale manufacturing to create and enhance something. These steps are useful for design, engineering, product reliability, and fabrication.
Building Stronger Seals Through Smarter Engineering
When there is a persistent sealing problem, it usually comes with multiple issues. The problems often stem from an entire thread of bad material selections, poor designs, and bad testing.
Applying better engineering to sealing systems enhances their reliability. Better tolerances, better testing, and the right choice of seal materials go a long way in improving product reliability.
