Seal technology for metal processing mills has come a long way, and
System Seals has led much of the new innovation for continuous
casters. One primary advancement is a move to PTFE Compounds as
the primary sealing component that is replacing the old V-Packing
designs. PTFE offers lower friction, greater precision and far more control
for continuous casters.

From a cost perspective, System Seals can custom engineer seal materials
and profiles for specific equipment to account for conditions such as
surface finishes, fluid compatibility and pressure trapping. Together,
these adjustments dramatically reduce maintenance costs, offer greater
reliability and increase uptime.

Replacing old V-packing is just the beginning. System Seals has also developed the industry’s
most advanced Polymer wipers and scrapers that virtually eliminate internal contamination
and reduce maintenance costs. New waterproof wipers prevent internal corrosion and keep
hydraulics running smoothly. Rigid scrapers from System Seals take exclusion to the next
level by removing caked on deposits that ordinary wipers can’t handle.

Standard bronze guide bushings are a burden to rework. New advancements in high-strength
composite bushings, such as MTC01 resin fabric from System Seals, handle high loads, are
extremely wear resistant and are easily replaceable. Grooves for new guide bands can be
machined right into the old bronze for an easy and affordable upgrade.

Design Optimization Process 

The System Seals Engineering Center uses an exclusive Design Optimization process that provides customers with the most advanced sealing solutions available. This step-by-step process outlined below includes the Technical Service Package from inquiry to installation. There is no faster or more effective service available in the industry.


We analyze every aspect of a seal application and all operating parameters. This is done for new OEM concepts, as well as existing equipment and maintenance and repair. We focus on how different seal components can be optimized as a more effective interdependent system.


Our Engineering Center does all the technical work for you, free of charge. This includes all technical work, drawings and even failure analysis if needed.


The full resources of our Research & Development lab are included with your Technical Service Package. This can include Finite Element Analysis, fluid compatibility testing and materials analysis.


Drawings are usually provided for review in 1-2 days and more quickly in emergency situations. The design review process often becomes a collaboration that enables customers to work directly with our Engineering Center to reach the best possible solutions.


After new designs are prototyped, tested and produced, System Seals helps with a variety of services after delivery, again at no additional charge, such as on-site installation, trouble shooting, training and ongoing technical support.
