The real reason why "maintenance frequency does not decrease" in high-temperature environments and the shortest route to take on-site (with checklist included).
In high-temperature environments, grease does not simply diminish; its "state" deteriorates due to hardening, separation, and carbonization. Even if there is some remaining, the lubrication function decreases, leading to increased sliding resistance, poor return, and fine seizure. If these warning signs are ignored, it will eventually progress to seizing or burning.
Therefore, the idea that "using high-performance grease eliminates the need for reapplication" does not hold true in high-temperature areas. What is important is to visualize the signs of abnormalities and to establish rules for inspection, cleaning, and reapplication.
Especially in die-casting molds, temperature changes, high surface pressure, and dust contamination overlap, causing lubrication conditions to fluctuate constantly. Maintaining a stable operational state takes precedence over reducing maintenance frequency.
【High-Temperature Sliding Component Checklist】
□ Is the return of the pin sluggish?
□ Are there any signs of seizure or dust accumulation?
□ Is the grease hardened or film-formed?
□ Is there any catching when starting to move?
□ After cleaning, is the appropriate amount reapplied?
Rather than forcibly reducing maintenance frequency, the realistic approach is to operate in a way that prevents stoppage accidents before they occur.
