Plastics like acetal, UHMWPE, nylon, PET, and PTFE are preferred over metal for wear and friction-resistant parts in packaging and conveying applications due to their superior durability and generally low coefficient of friction, which helps minimize wear on moving components and increase part life. These plastics are lightweight and self-lubricating, reducing or eliminating the need for external lubrication and allowing for their use in environments where lubrication is not recommended or impossible.
Polycarbonate is a popular material choice for enclosures and safety guards in the packaging and conveyign industries. A nearly unbreakable thermoplastic, polycarbonate has exceptional impact resistance, optical clarity, and durability. These properties allow clear visbility while providing reliable protection for monitoring operations. Polycarbonate is lightweight and can operate over a wide temperature range, allowing for its use in places where glass or metal may not work. Polycarbonate is versatile and can be thermoformed, machined, fabricated, or bonded using solvents.
