For sealing system critical battery housings, manufacturers have multiple technologies and challenges to factor into the decision making process. Seal integrity, performance and durability must be closely scrutinised, alongside the process of installation itself and the pressure it puts on production schedules. The foam gasket, which is often applied by hand or robotically as part of a Cure-in-Place (CIP) process, is one of the most common solutions across the mobility sector. But how does this technology compare to the solid rubber alternative? Here, we compare and contrast to see where the advantages clearly stand out.
