Considered by few to be an out-dated molding system
that was replaced by injection molding, Compression Molding is often
a better solution for certain applications requiring thicker walls,
tighter tolerances and better dimensional stability.
Occasionally, compression molding is the ONLY
possible molding method for certain materials and part designs or
requirements. As the original service L.W. Reinhold Plastics offered
in 1943, compression molding has become our prime specialty, and the
key to our more than 67 years of success. Unlike the few other
compression molders in the world today, our 9 presses were
specifically designed and custom built by our founder Lyle Reinhold
to be capable of producing 5,000psi of cylinder pressure compared to
the industry standard of 2,200psi.
That means we can produce a higher packed, more
dimensionally stable, and better structurally sound part than our
competition. This also means we can run larger parts on a smaller
press, thereby saving our customer money.
