Whether your process is Injection Molding, Blow Molding, Extrusion Molding, Reaction Injection Molding, you can improve the speed and efficiency of your molding operation. The smooth, micro-nodular surface of Armoloy chromium coatings enables you to get shorter fill and cycle times. Armoloy reduces maintenance and downtime problems by extending the life of your mold components by as much as 10 fold. The extremely hard surface of Armoloy (HRC 78) protects against wear, particularly when glass-filled and mineral-filled resins are being formed. Mold surfaces stay cleaner for longer periods and require less maintenance with Armoloy coatings. Even burnt on plastic or rubber can be quickly removed. Armoloy coatings can be applied to all ferrous and most non-ferrous metals, including Ampcoloy Bronze and Beryllium Copper. Armoloy coatings can maintain the textured surfaces of existing mold finishes or can be polished and buffed to improve reflectivity to SPI A-3.

The mold components that have been treated with Armoloy most often include:
Cavities, Spider Dies, Die Retainers, Coextrusion Diverters. Extrusion Dies, Blocks, Rams, Spreaders, Breaker Plates, Nozzles/Ports, Gates, Lifters, Adapters, Plungers
-> Plastics & Rubber Molding

Linear Motion components are prevalent in many industries including Packaging, Material Handling, Aerospace, Pharmaceutical, Semiconductor, Factory Automation, Robotics, Solar and Wind Energy. Armoloy chromium coatings protect these components from wear and corrosion, improve speed of operation and reduce noise levels by reducing friction. In particular, when Armoloy coated surfaces run against each other, friction is reduced to the minimum.The precision coating thickness achieved with Armoloy is a welcome benefit to design Engineers and manufacturers, and unlike conventional chrome plating. Armoloy does not require any post grinding or post polishing processes. Choosing Armoloy to coat components made of carbon steel reduces costs and provides superior performance to stainless steel.

The components that have been treated with Armoloy most often include:
Linear Rails, Guide Ways, Slides, Carriages, Spindles, Shafts, Ball Screws, Lead Screws, Roller Bearings, Rack and Pinions, Profile Rails, Positioning, Devices
-> Linear Motion

The lifetime and performance of bearings can be improved by the application of Armoloy chromium coatings. Manufacturers can choose standard ferrous steels such as SAE 52100 and coat their bearing components with Armoloy to obtain corrosion protection equal to or better than 440C Stainless Steel. Additional features such as improved wear resistance, less fatigue resistance, and improved machinability add to the overall cost benefits. Armoloy can successfully be used on bearings of the highest tolerance (ABEC 9) with engineering deposits of .00005” - .0001”. The unique, nodular surface of the Armoloy coatings reduces surface friction in the bearing raceways. Surface hardness is increased to HRC 78. Bearing operating temperatures may be reduced which may also increase lifetime performance.

The bearing components that have been treated with Armoloy most often include:
Ball Bearings, Inner Races, Blocks, Needles, Linear Shafting, Roller Bearings, Outer Races, Carriages, Slides, Geared Bearings
-> Bearings

Armoloy TDC (Thin Dense Chromium) coatings reduce scrap rates and lower labor costs in the automotive industry. The smooth, micro-nodular surface of the Armoloy coatings promotes waste reduction by minimizing the use of lubricants. Clean-up and set-up times are subsequently reduced. Armoloy reduces premature wear and pick-up, allowing more hits per run and less maintenance downtime. Armoloy is 99+ percent Chromium and welding maintenance can be accomplished without compromising the coating. Armoloy is guaranteed not to chip, flake or peel. The coatings are especially successful in die-casting applications. All types of nitride surfaces can be successfully coated. All ferrous and most non-ferrous metals can be successfully protected.

The components most often treated in the Automotive Industry include:
Forming Tools/Punches, Draw Dies, Plastic Molds, Rubber Molds, Thrust, Bearings, Ball Nuts, Stamping Dies, Progressive Dies, Linear Motion, Welding, Spatter Buildup, Clutches
-> Automotive

Armoloy Chromium coatings provide outstanding wear and corrosion protection for machine tools of all types. The Armoloy process ensures the deposition of precise (normally .0001” to .0003” thick) deposits of 99% chromium to virtually any metal surface, with the exception of Aluminum, Magnesium and Titanium. This low friction, nodular surface finish is highly beneficial for metal-to-metal contact between machine tool components. For minimal friction designs, Armoloy should be applied to all metal surfaces that are in moving contact with one another. Since Armoloy is a cold processing technology (<180 degress F.) the base metal will not be annealed or distorted, and the risk of hydrogen embrittlement will be minimized. Armoloy chromium coatings are particularly beneficial to those base metals that have been hardened in the anticipation of high wear… in these cases the surface hardness can be increased to HRC 78. Armoloy coatings can be applied to nitride surfaces. All nitrided components submitted for Armoloy processing should be clearly identified.

The mold components that have been treated with Armoloy most often include:
Shafts, Bearing Races, Spindles, Gears, Splines, Slides, Guide Ways, Pins, Linear Rails, Rollers, Collets, Cams, Bolts, Locknuts, Housings, Retainers
-> OEM Machine Tools

Armoloy® chromium coatings protect a variety of metal components that are utilized in the food and beverage industry. Component lifetime is extended by protection against wear and corrosion. Friction is reduces by the unique, nodular, thin dense chromium surface finish.
This finish makes food industry lubricants more effective by trapping them in its micro nodular surface. Armoloy is FDA/USDA approved for use, without concern, on food processing equipment. Armoloy is washable, non-toxic, and non-absorbent. Its smooth, continuous surface can be repeatedly cleaned and disinfected. Amoloy firmly adheres to all grades of stainless steel and will not chip, crack, flake or peel.
Armoloy coatings can withstand temperature above 1400 degress F.

The components that have been protected by Armoloy most often include:
Production Machinery, Packaging Equipment, Augers, Shafts , Cutting Blades, Feed System Hoppers, Chopping and Coring Tools, Laboratory Equipment, Molds, Rails, Chutes, Rollers, Slides, Sealing Equipment
-> Food Procesing & Packaging

Die Casting companies chose Armoloy chromium coatings to increase their production efficiency and reduce their maintenance costs. Armoloy increases the wear resistance of die components due to its hardness (HRC 78). Hardened metal parts benefit the most with the Armoloy surface finish. The low coefficient of friction of Armoloy’s nodular surface provides high lubricity and holds lubricants better than the base metal.The major benefits of Armoloy chromium coatings are reduced drag, reduced soldering problems, corrosion protection (especially during storage of dies not in use) and substantial reduction of lubricant usage during die casting operations.

The components that have been treated with Armoloy most include:
Core Pins, Ejector Pins, Cavity Inserts, Blade Inserts, Removable Cores, Slide Cores, Interchangeable Cores, Weight Saver Inserts
