Is it possible to prevent lubricants for ejector pins from being transferred to demolded parts?
Low quality or non-specialized lubricants are often not thermally stable; the film created by these lubricants can come off the ejector pins and reach the tips of the pins, where the material may be transferred to the parts and end up as a deposit on the demolded part. Thermally stable, special purpose lubricants have been developed for ejector pin applications that will remain on the ejector pins and will not be transferred during processing.
