These bushes are used in guide pillars and ejector systems to ensure smooth, precise movement of mold components.They reduce friction between moving parts, improving alignment and reducing wear.
Since they are self-lubricating, they eliminate the need for frequent manual lubrication, which is ideal for machines that run continuously or in hard-to-access areas.
By minimizing metal-to-metal contact and reducing wear, these bushes help extend the life of molds and machine components.
Smooth, low-friction movement contributes to faster and more consistent mold cycles, enhancing productivity.
Injection molding involves high clamping forces and elevated temperatures. Self-lubricating bushes made from materials like bronze with graphite plugs or PTFE composites can withstand these conditions.
