Custom-fabricated molded seals are called for in situations where deployment or basic operating conditions push standard sealing elements to their limits. These custom-molded seals are precisely tailored to the specic application at hand and, as their name implies, are manufactured using special forming molds and dies. Optimal shaping of the sealing lip and the right choice of material and hardness are crucial prerequisites for a reliably functioning molded seal. The natural resilience of elastomeric sealing materials provides a virtually constant sealing force. 01.02.11 16:53
