Mold thimble lubricant spray oil
Pain Points
Running injection molding, die casting and precision mold production, you must have encountered these troublesome issues caused by poor ejector pin lubrication:
- Ejector pins stick, jam or seize under continuous high temperature, leading to unstable ejection, part whitening, cracking and high reject rate
- Ordinary lubricant carbonizes, forms sludge, turns black and leaves residue on mold cavity, contaminating finished plastic parts
- Lubricant drips and creeps easily, polluting mold surface and products, extra cleaning work wastes production time
- Frequent relubrication increases downtime; ejector pins and sleeves wear fast, shortens mold service life and raises mold maintenance cost
- Poor compatibility with engineering plastics, leaving oil stains, affecting painting, plating and secondary processing of molded goods
Solution
Our Mold Ejector Pin Oil / High Temperature Thimble Lubricant is synthetic formula specially developed for injection mold ejector pins, thimbles, ejector sleeves and sliding mold components. This high-performance ejector pin lubricant forms a tough, adherent lubricating film after spraying. It resists high temperature, anti-carbonization, anti-seize and anti-wear. It will not drip or creep easily, keeps low residue and avoids contaminating mold cavity and plastic products. It reduces friction of reciprocating ejector movement, eliminates pin sticking, stabilizes ejection action, lowers defective rate, extends mold life and cuts mold maintenance frequency. Silicone-free optional formula, compatible with most thermoplastics, safe for post-process painting, coating and plating.

FAQ
Q1: Is this ejector pin lubricant silicone free? A1: Yes, standard version is silicone-free. It will not cause surface defects, and fits painting, electroplating and surface coating after molding. We also support silicone-containing customized formula if you need.
Q2: What is the max temperature this thimble oil can withstand? A2: Stable working temperature up to 240℃, suitable for high-temperature engineering plastic molding such as POM, PC, PEEK, effectively prevent carbon deposit and pin seizure.
Q3: Will it stain or contaminate plastic molded products? A3: The formula has strong film-forming property and anti-creep performance. It adheres to the ejector pin without dripping and flowing to cavity, low residue, greatly reduce product oil stain risk.
Q4: Can it be used on angle lifters and mold slides? A4: Yes, this mold ejector pin oil works well for all sliding mold moving parts including angle lifters, slides and core pulling structures.
Q5: Do you support OEM private label and bulk order? A5: Yes, we accept OEM & ODM, custom label, package and formula. Contact us for bulk price and COA document.
