HEEF® HMC

New additive formulation providing highest quality

The HEEF® HMC process creates a hard chrome deposit with a finer and denser network of micro-cracks enabling superior corrosion resistance.

Unlike normal hard chrome processes the new HEEF® HMC process is able to maintain this denser, micro-cracked structure even when the current density is increased, allowing productivity improvements without compromising on quality.

The HEEF® HMC deposit exhibits all of the benefits of the famous HEEF® processes: high hardness, low friction, excellent wear resistance, ease of use and high quality while improving corrosion resistance with the denser micro-cracked structure.

HEEF® HMC

exhibits all of the benefits of the famous HEEF® processes: high hardness, low friction, excellent wear resistance, ease of use and high quality while improving corrosion resistance with the denser micro-cracked structure.

HEEF® 25

is the most commonly used member of our hard chrome systems. It has been successfully implemented for every application that calls for a functional chrome deposit. These include but are not limited to automobile parts such as shock absorbers and strut rods, engine valves, piston rings, brake pistons and cylinder liners, and others like hydraulic rods, agricultural equipment, mining, oil and gas components and rollers of all types including rotogravure.

HEEF® PR

was developed especially for the plating of cast iron piston rings, but has now found a large use for diesel, auto and locomotive cylinders as well. HEEF® PR has all of the same benefits as our HEEF® 25 but this process also has the attribute of a very low chemical etch rate on exposed cast iron. Meaning that the inside no longer needs to be protected from chemical attack using a lacquer or similar technique.

HEEF® FC

is able to plate at much higher current densities than was previously possible. Commercially it is being used at over 200 A/dm² (13 ASI) in applications where the part geometry and current carrying capabilities are appropriate, giving higher outputs from a plating line.

HEEF® KR

is a high quality process able to improve the corrosion resistance of the chrome deposit by forming a denser network of finer and more numerous micro-cracks.

HEEF® T

enables platers to work completely lead-free by utilizing platinized titanium anodes. It uses Trivalent Chromium Control (TCC) technology to help control the level of trivalent chromium when these Pt/Ti anodes are used.
