Mold grease for high-temperature molds

Review selection criteria due to galling, grease depletion, and contamination of molded products. Are you facing any of these issues in the sliding parts of your molds? - Galling or seizure occurs - Grease depletion happens quickly, leading to frequent reapplication - Oil stains or grease adhere to molded products - Grease solidifies in high-temperature areas, making cleaning time-consuming When selecting grease, it is important to not only consider heat resistance but also to organize the problems occurring and the actual usage conditions. ■ If you are concerned about galling or seizure** Check the load and sliding speed, and consider load-bearing capacity and lubrication performance. ■ If you are concerned about grease depletion** In addition to retention in sliding parts and operating temperature, review the amount applied and the interval for lubrication. ■ If you are concerned about contamination on molded products** Check the ease of oil separation and scattering, as well as the application position and amount. Note that even with the same symptoms, factors such as clearance, wear, and foreign substances may be involved. Confirming both the performance of the grease and the condition of the equipment is the first step in selection. For those struggling with selecting mold grease Please inform us of the application location, temperature, and current symptoms.

Are you troubled by mold burning, wear, or grease bleeding? Selecting mold grease that matches the usage temperature, sliding conditions, and operating environment is important. At M&M Co., Ltd., we offer a variety of greases tailored to different applications, from high-temperature greases for die-casting molds to fluorine greases, general mold greases, food container mold greases, and greases for O-rings and gaskets. We have prepared an introductory document that allows you to compare mold greases by application and temperature. If you are unsure which grease to choose, want to review the grease you are currently using, or need to address high temperatures, burning, or bleeding issues, we can provide recommendations based on your usage conditions. Please feel free to contact us if you are having trouble with mold maintenance or grease selection.

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.
