These four defects may look different, but most of them can be traced back to the same three root causes.
When troubleshooting molding parameters and material issues, many factories overlook a quiet source of wear and failure — the routine lubrication of ejector pins and other moving mold components.
Insufficient lubrication of ejector pins over time can lead to:
Increased ejection resistance, causing ejector marks, whitening, and cracking
Accelerated wear on the ejector pin surface, reducing mold service life
Unstable ejection movement, resulting in inconsistent demolding positions
The same applies to sliders, lifters, core-pulling mechanisms, guide pillars, and guide bushings. Inadequate lubrication accelerates wear and can directly affect the appearance and quality of finished parts.
The Falcon 101, S-305, S-205, and S-206 lubrication and maintenance series provide targeted solutions for different mold components and operating conditions.
