Plastic Injection Molding Design and Manufacturing
rollers offer many distinct advantages over metal,
plastic, or ceramic rollers. Urethane rollers are very
resistant to abrasion, and absorbs shock very well.
Urethane coated rollers have minimal slippage, and reduce
the likelihood of damaging the handled material. Urethane
rollers operate at reduced sound pressure and do not
oxidize or corrode in normal industrial environments.
Urethane offer improved embitterment, have minimal
limitations of urethane rollers are a maximum operating
temperature at approximately 200 F. Excessive steam
exposure will degrade material, and selected chemicals
will also deteriorate material.
Urethane rollers are typically manufactured using a cast or mold process over the desired bushing or core. Normally some post casting or molding machining is required to ensure the roller is at the desired diameter and length.
