MLP Thin Dense Chrome Plating

Introducing exclusive treatment combining our thin dense chrome plating with a proprietary polymer compound. The addition of a polymer compound heated until it flows into the cavities or "pores" in the nodular surface adds built-in lubrication. This is further enhanced by polishing the surface while the polymer is still fluid, resulting in a smoother, slippery finish that substantially reduces the heat and friction problems created in many applications. Unlike many other industrial platings MLP thin dense chrome will not separate from the base metal. In addition, with a processing temperature of 195°F there will not be any affects on the tensile strength of your tooling or parts.  Although harder chrome platings are available, outperforming MLP thin dense chrome is a tough task with all the additional benefits it has to offer.

MLP thin dense chrome has many of the physical properties of our Thin Dense Chrome plating but with the impregnation of our proprietary polymer compound.  MLP is a relatively low temperature plating. The TDC is applied at 140° F. The Polymer is applied at 185° F.  The base metal remains unchanged by the surface coating at these temperatures, therefore the desired properties of the substrate material are intact beneath the plating. Inside diameters from .250” and larger can be coated in most cases. Consistent minimal thickness requires no design changes. MLP Thin Dense Chrome plating has proved to be a viable coating for industrial tooling for nearly two decades.

Independent Test


The graph to the left represents test results performed by Concurrent Technologies Corp.  These tests measured the difference in ejection loads under identical conditions.  Various types of materials with a variety of lubricant % were compacted to compare the difference between an uncoated die vs. an MLP Thin Dense Chrome coated die.  The left side of the chart represents ejection loads in lbs.  The MLP Thin Dense Chrome plated die required approximately 43% less ejection load without lubricant.

Is MLP Thin Dense Chrome Plating Expensive?

There are several factors that are used to determine the cost of our MLP Thin Dense Chrome plating. Typically the cost of coating most tools is usually less than 10% of the total cost of making it.

Why coat with our MLP Thin Dense Chrome?

  • Longer Life - Saves money

  • Shorter Cycles - Cooler operating temps means more product per hour

  • Better Release - Essential for maintaining trouble free production

  • Finish Stays In Tact - Helps keep integrity of finish intact longer

  • Reduction In "Down Time" - Savings can be huge
