What type of lubricant should I use for the moving parts of my candle making machine?

For the moving parts of your candle making machine, it's best to use a food-grade lubricant. This is important because candle making machines come into contact with materials that are often intended for human use or consumption .

Food-grade silicone lubricants are a good choice as they are safe, have a wide temperature range tolerance, and resist oxidation. They can handle the heat generated by the machine without breaking down and causing damage.

Another option could be food-grade mineral oil. It provides good lubrication and is relatively inexpensive. However, it may need to be reapplied more frequently than silicone lubricants.

Avoid using general-purpose lubricants or oils that are not food-grade as they can contaminate the candles and pose a health risk.

For instance, if your candle making machine has a conveyor belt with rollers, a few drops of food-grade silicone lubricant on the axles of the rollers can keep the belt running smoothly and reduce wear and tear. Make sure to apply the lubricant sparingly to avoid any excess that could drip onto the candles or other parts of the machine.
