Dura Slick: Mold Release Coating
Proprietary Nonstick Coating for Rubber & Plastic Molding
Dura Slick is a proprietary nickel-based mold release coating for rubber and plastic molding companies. With a low coefficient of friction makeup and a breakdown temperature of 1650 F, Dura Slick is a perfect solution for high-usage applications that are prone to sticking, wear, and galling concerns.
This innovative nonstick metal plating is a preferred solution in the tool and die, rubber, and plastic injection industry thanks to the excellent release of plastic and rubber parts from molds. This mold release coating is especially useful for plating medical molds, challenging thermoplastics, high-cavity molds, and other applications that require additional release to produce quality parts.
Dura Slick: Specifications & Mold Release Properties
- 56-58 RC rating as plated, standard hardness for most plating applications
- 67-68 RC rating can be achieved by post-baking at safe temperatures to provide exceptional hardness for high-wear or use applications
- Plating deposit .00003-.010” thick
- Excellent for high-wear and large volume molding applications
- Dura Slick creates a uniform plating deposit of both nickel and low-coefficient-of-friction proprietary makeup
- Prevents galling that can lead to severe damage, ruined tolerances, and component damage or defective parts
- Excellent and uniform adhesion properties for almost all tool steels and aluminum
- Breakdown temperature: 1650° to 1790°F
Using Mold Release Coatings to Salvage Surfaces
Dura Slick can also be used for salvage or in instances where engineering changes are needed in a molding surface. PFI can mask off the entire part and concentrate on the area that needs build-up, leveraging our expertise in selective plating processes.
Dura Slick plates pit-free at .010, making it one of the most requested platings for plastic injection tooling. Dura Slick can also be post-polished to an A2 finish, making it one of the best coatings on the market because it is a slippery, hard, corrosion-resistant protective coating with a breakdown temperature of 1650 F.
Mold Release Coatings Reduce Cleaning Downtime
Mold release sprays leave residue behind with every application. That residue settles into vents, parting lines, dumps, and ejector pin bores, eventually forcing a cleaning stop. Manual coverage makes it worse: some spots collect too much material, some spots don’t get enough, and the resulting thin spots wear out first and force an early recoat instead of a simple touch-up.
A permanent coating like Dura Slick cuts cleaning downtime by solving that problem at the source. One application covers the mold for good, with no mid-run respray and no fresh residue building up between runs. The plating also reaches deep recesses and fine detail evenly, closing off every thin spot before it can start.
Why Choose PFI for Your Mold Release Coating Needs
PFI has been in the metal finishing business since 1982. Many of the technicians on our floor today started here in those early years. That same experience shows up in every batch of Dura Slick, holding hardness and lubricity steady from one job to the next.
The Pennsylvania Department of Environmental Protection recognized PFI for outstanding achievement among the state’s metal finishers. Dura Slick carries that same standard into every batch.
