Type III “Hard” Anodizing, for aluminum substrates, is desirable for applications requiring an extra hard surface and increased oxide thickness. This process uses sulfuric acid at a much lower temperature and higher current density that results in a much thicker and harder surface. Magnaplate processes parts with Type III Anodize, Classes 1 and 2. We manage key critical anodizing factors such as temperatures, chemistries and amperages, and employ an automated ramping process to ensure a uniform application every time.
All too often, anodize alone does not provide the level of protection required. For these more demanding applications, Magnaplate’s proprietary anodize-based processes can provide solutions. Magnaplate’s coatings have the additional benefits of dry lubricants or polymer impregnation, to further expand the use of aluminum, titanium and magnesium for parts in challenging conditions.
TUFRAM® - Tufram combines the hardness of aluminum oxide ceramic with the desirable properties of selected Magnaplate proprietary polymers and dry lubricants. These features allow Tufram to outperform conventional hard anodizing and similar processes when it comes to wear and corrosion resistance, friction reduction, hardness and permanent lubricity.
MAGNAPLATE HCR® - Combining the hardness of aluminum oxide ceramic with the sealing action of metallics and proprietary polymers, Magnaplate HCR imparts hardness and previously unattainable corrosion resistance and permanent lubricity to aluminum and aluminum alloy parts.
CANADIZE® - This permanent, dry lubricated and thin ceramic coating protects titanium alloy parts against wear, abrasion, adhesion, galling and seizing. Canadize not only lowers the COF of titanium substrates, but also prevents hydrogen embrittlement.
MAGNADIZE® - Magnadize offers superior oxidation prevention for magnesium alloys, protecting against wear, outgassing and thermal extremes while minimizing friction. It can also provide corrosion resistance and lubricity for both the application and alloy being used.
Multi-part assemblies should be anodized before assembly. Due to the strong alkaline and acids involved, studs, pins, threaded inserts or standoffs may corrode. Corroded materials in the anodizing tanks can affect current flow during electrolytic processes. In addition, gaps between components can trap chemicals and cause complications.
In general, tighter angles are challenging. For example, the coating may not reach a 90-degree corner. C surfaces are less difficult to coat, while radiused surfaces are better to work with. Parts with extremely thin areas may not be conducive to the anodize process. It can be difficult to obtain a uniform thickness with deep blind holes within parts.
High strength alloys or materials such as titanium can develop hydrogen embrittlement, which can cause the part to crack and fail under loads. During the cleaning process, which often involves acidic materials, certain alloys will impart hydrogen to the surface of the metal, which causes the embrittlement. Specialized procedures can be performed on the part after coating, or alternative cleaning processes can be used to expel the hydrogen from the surface and avoid the issue.
Yes, they do. Our coatings comply with a variety of specs including AMS 2482, AMS 2488, MIL-PRF-8625, MIL-A-63576, MIL-DTL-5002 and MIL-M-45202. Please contact us at email@example.com for any additional questions regarding standards and specifications.
Many of our anodize-based coatings comply with USDA/FDA food codes (CFR 21 175.300).
A number of factors can influence the cost of your anodized coating. For example, hard anodizing is performed at a lower temperature and at a higher current and voltage than clear anodizing. The higher energy consumption required can add to your cost. Other factors include the time and effort required for masking and racking, the amount of rinsing needed — especially when smaller features are involved — and poor, unclear specifications can lead to additional work.
Magnaplate processes parts with electroless nickel-based coatings. Electroless nickel is a chemical process which does not use electric current. These coatings are uniform, suitable for parts with complex shapes and capable of holding tight tolerances. They provide wear and corrosion resistance for ferrous and non-ferrous metals including aluminum, and are extremely useful in the automotive and aerospace industries when it is advantageous to replace heavier metals such as steel.
There are three types of electroless nickel coating baths:
When traditional electroless nickel plating cannot satisfy your surface protection requirements, Magnaplate’s proprietary processes can provide solutions. Our electroless nickel-based coatings for most metals have the added benefit of select dry lubricants or polymer impregnation to boost the performance of parts in demanding applications.
Nedox® creates a harder-than-steel, self-lubricating layer of protection against wear, friction and corrosion, exceeding the physical properties of many common industry coatings. Less-durable metals can achieve the longevity and performance of chrome and stainless steel.
Nedox® PF-F lowers the coefficient of friction and prevents wear in parts that cannot tolerate particulate generation. Other features include hardness up to 68 Rc, high-temp operation and excellent outgassing properties.
Magnaplate HMF® is well-suited for ferrous metal, copper or aluminum alloy surfaces that require a mirror-smooth finish with a low coefficient of friction. Magnaplate HMF achieves a micro-finish as low as 4 Ra and hardness up to 68 Rc.
Hi-T-Lube® has a record-breaking low coefficient of friction (0.03) and protects against abrasion, wear and galling under high surface loads, extreme pressures and temperatures.
Typically, we are holding +-.0002-inch tolerance on coating thickness. The thickness is usually held between .0003 to .0025 inch.
There are several issues that can affect the electroless nickel plating on a part. One relates to sharp corners. Parts need to have a radius in order to support the plating and minimize the potential for chipping at the corner. The radius should be in relation to the thickness of the plating being applied. Another issue relates to parts that have cavities. If parts are not fixtured properly, air pockets can form resulting in areas of the part that will be void of coating. Proper positioning and careful monitoring are essential to ensure air pockets do not form during processing.
High hardened substrates can create a twofold problem. First, the thickness of the coating should be minimal to reduce the potential for the coating to delaminate due to stresses as the thickness builds. The second issue is that there is a greater potential for hydrogen embrittlement. High hardness parts will need a post hydrogen embrittlement bake, within four hours of plating, to ensure that hydrogen embrittlement does not occur in the substrate.
Mixed-metal parts also create issues. Different cleaning processes may be required for one substrate compared to another. The result can be one material coated and the other not or, worse, being damaged. Parts made of mixed materials should be assembled after plating if possible.
Our coatings comply with a variety of specifications including AMS 2404, ASTM B733, MIL-C-26074 and MIL-DTL-5002. Some of these specifications identify certain electroless nickel coatings by Class (1 through 6) and Grade (A, B or C). Class indicates heat treatment, if performed, and Grade relates to the coating's minimum thickness. ASTM B733 has five types, specifying the phosphorous content of the coating. Please contact us at firstname.lastname@example.org for any additional questions regarding standards and specifications.
Many of our nickel-based coatings comply with USDA/FDA food codes (CFR 21 175.300).
Many factors influence the cost of an electroless nickel job. The size and complexity of the part play a role. How many parts can be processed at once? The substrate determines the complexity of the process path. Is there special fixturing or positioning of the part required? Parts may have intricate cavities that require multidirectional movement to ensure that air isn’t trapped within the cavities. Specific tooling fixtures may be required to process the job. Does the part require masking? Time and materials need to be considered. Low surface finish requirements increase cost through increased inspection and possible post-processing. Conforming to specific standards may increase the cost through added requirements such as testing.
Our mid-phos electroless nickel line’s capacity is 22 by 2.9 by 2.5 feet, with a maximum weight capacity of four tons. For high-phos, our capacity is 7.9 by 2.9 by 3 feet, with a maximum weight capacity of two tons. For aluminum, we can process parts up to 3.9 by 1.8 by 3.4 feet.
Cost-effective and ideal for large surfaces, thermal spray abradable coatings and thermal barrier coatings can be applied to most metals. A great choice to advance sustainability efforts within your facility, they can restore or repair worn parts and extend service life. These processes utilize materials such as powders, wires or rods that are fed through special guns. The materials are heated or melted, then sprayed in a gas stream onto a substrate. Benefits include wear, abrasion and corrosion resistance during exposure to high temperature environments. Thermal spray coatings are used in a wide variety of industries including aerospace, oil and gas, food processing, paper, packaging and transportation.
There are several types of thermal spray processes. Each has different properties and is applied using different methods.
High Velocity Oxygen Fuel (HVOF)
Traditional thermal spray coatings have many benefits, but it can be difficult to narrow them down to one coating that has all the properties needed in your particular application. Magnaplate’s PLASMADIZE® composite coatings offer the additional benefits of infused polymers, dry lubricants, metals and/or ceramics to achieve desired properties. These include operating in temperatures up to 1,000 F, exceptional wear resistance, hardness and release, and USDA/FDA compliance. PLASMADIZE® coatings can be applied utilizing advanced techniques of robotic deposition for consistent, repeatable results on large volume, complex parts.
Yes. We developed PLASMADIZE® options specifically for effective release of adhesive tapes, hot melt glue and similar sticky substances.
Yes. One of our PLASMADIZE® coatings was formulated for exceptional PVC release and wear-resistant properties in applications up to 500 F.
PLASMADIZE® coatings can be applied in substantial thicknesses, starting at .002 to .010 inch, to extend a part’s service life.
PLASMADIZE® coatings can be used to combat corrosion from many chemicals used in the pulp and paper, fertilizer, paint and printing ink industries to name just a few. These include many acids, alkalis, most organic solvents, chlorides, sulfites, thiosulfates and bleaching chemicals. Surfaces can be cleaned with just water, often eliminating the need for harsh cleaners or detergents. PLASMADIZE® can also resist the pH range encountered in many washdown solutions.
Yes. We offer versions of PLASMADIZE® that comply with the FDA’s CFR 21 175.300.
The part’s size and complexity and the desired coating thickness play large roles in determining cost. Due to the nature of application methods, deep internal holes can present challenges. Specialized techniques can be developed to spray into certain holes, and this will affect pricing. Masking can be a time-consuming step, also adding to overall cost. A wide variety of raw materials such as powders and gases are used in these coatings, and their prices vary.
Depending on the type of coating and part configuration, we can process parts up to 20 by 10 by 10 feet with a weight limit of 4,500 pounds.
Polymer coatings are various types of chemicals applied to a substrate utilizing a spray, spin dip, electrostatic or fluidized bed technique. Designed for many ferrous and non-ferrous metals, they are used to protect against corrosion or to provide non-stick properties at high temperatures. Polymer coatings have been around for about 100 years, and are found in countless consumer and commercial products such as cookware and medical devices.
LECTROFLUOR® coatings surpass the properties of conventional polymer coatings to protect ferrous, non-ferrous and mixed metal parts in harsh environments. A significant advantage with LECTROFLUOR® is that each coating can be tailor-made to meet specific requirements. Coatings within the LECTROFLUOR® family offer excellent release properties and low COF along with UV, chemical and corrosion resistance. They have exceptional electrical properties and can endure a broad service temperature range. Ideal applications include pumps, valves, sealing dies, molds, housings, rolls and stirring equipment. Each LECTROFLUOR® type provides specific characteristics and benefits, such as being able to withstand washdown cleaning agents or the durability needed for rubber molding. Specialized application techniques have been designed to resist potential microcracking and provide pinhole-free coatings. We utilize a variety of polymers and fluoropolymers such as ETFE, FEP, PTFE, PFA or dry lubricants in our LECTROFLUOR® coatings to impart the properties necessary to combat the conditions your parts encounter.
Yes. One of our LECTROFLUOR® coatings, with a thickness range of 0.0005 to 0.0015 inch, was formulated specifically to provide exceptional PVC release and wear-resistant properties in applications up to 500 F.
Yes. Many of our LECTROFLUOR® coatings comply with USDA and FDA codes for use in the food, pharmaceutical and packaging industries on parts such as hoppers, augers, rollers and seal bars.
Our LECTROFLUOR® family of coatings utilizes a wide variety of raw materials, and pricing varies. Each of these materials requires a particular method of application, with some more time-consuming than others. Some LECTROFLUOR® processes require heat curing, so oven cure time is a price factor. Masking also affects overall costs, as this is a labor-intensive aspect of any job. Part configuration, such as those with deep holes or complex geometries, also always factors into cost.
Depending on the type of coating and part configuration, we can process parts for polymer coatings up to 18 by 8 by 6 feet. These processes have a weight limit of 4,500 pounds.
Titanium nitride physical vapor deposition (TiN PVD) is a complex process performed in a chamber in a vacuum environment. The resulting gold-colored coating is a strong, thin, uniform and extremely hard surface layer. These coatings can be applied to many ferrous and non-ferrous metals including steel, titanium, and even aluminum. Unlike chemical-based processes, PVD can be used on parts with sharp edges, or those requiring extremely tight tolerances. PVD coatings have better wear and abrasion resistance than stainless steel, and can greatly extend the service life of parts.
MAGNAGOLD® and GOLDENEDGE® are Magnaplate’s enhanced TiN PVD coatings that provide wear and abrasion resistance beyond conventional PVD processes. These surface treatments are applied in low temperatures, preventing distortion or loss of hardness of metal parts. MAGNAGOLD® and GOLDENEDGE® can operate in a wide range of temperatures (-360 to +800 F), are resistant to impact forces, and are well suited for parts with tight dimensions. Benefits include chemical resistance, low COF, hardness up to an equivalent of Rc 85, and non-stick properties. These coatings resist most acids, alkalis, fluxes, solder and weld spatter. MAGNAGOLD® is ideal for tooling such as drill bits, punches, dies and electronics. GOLDENEDGE® is intended for sharp-edged parts such as blades, knives, grinders and slicers. This coating has a fine grain structure as a result of its low temperature application, and produces a thin, dense, hard surface with a low COF that minimizes wear of cutting edges.
PVD (Physical Vapor Deposition) is a process in which titanium raw materials are evaporated in a vacuum. The vapor reacts with nitrogen, and is then condensed back into a solid film on the substrate. CVD (Chemical Vapor Deposition) involves the use of raw materials in gaseous form in the process. The gas byproducts from CVD can be hazardous and flammable. CVD is performed at extremely high temperatures of 1,800+ F, which can distort metal parts, requiring vacuum heat treating to restore the hardness of the substrate.
Both coatings can be applied in a thickness of between 0.00004 and 0.0002 inch.
The PVD chamber is not designed to hold many parts at one time. As with any coating job, factors such as the complexity and configuration of the part, if masking is needed, and deep holes will all affect costs.
Due to the nature of this process, and the necessity of fixturing parts within the PVD chamber, we recommend you contact us to discuss your application in detail.
Thin dense chrome is an electroplating process which creates a chrome coating thinner and denser than standard chrome plating. These coatings offer protective benefits for parts including increased hardness, low COF, as well as corrosion, wear and abrasion resistance. This is also an ideal coating choice for parts in a high temperature environment.
Magnaplate’s DYNALOY® surface treatment offers a higher level of corrosion resistance than standard thin dense chrome. Due to the coating’s low processing temperature, parts can be coated at any time in their service life without adversely affecting the base material’s properties. DYNALOY® has a hardness of 72 Rockwell, and can withstand operating temperatures up to 1,600 F. It is compatible with most ferrous metals, and has an attractive matte silver finish. It creates a thin microstructure with precise reproduction of substrate’s original surface morphology. Since DYNALOY® is so thin and uniform, even on edges, there is no need for grinding or machining steps after coating. Applications include automation, packaging and hydraulic equipment, conveyors, pumps, valves, punches, bearings and a wide variety of tooling and space components.
Unlike conventional hard chrome plating, DYNALOY® is void of micro-cracks. During hard chrome plating, micro-cracks can occur when internal stress exceeds the tensile strength of the hard and brittle chromium. Stresses do not have an opportunity to build up with DYNALOY® , primarily because the coating is so thin. No micro-cracks means enhanced corrosion resistance with DYNALOY® .
While the base metal’s properties such as hardness and porosity can impact individual results, DYNALOY® can resist attack by most organic and inorganic compounds.
No, application of a DYNALOY® coating will not affect tolerances due to its extremely thin and uniform nature, with a thickness range of 0.0001 to 0.0003 inch.
Depending on the type of coating and part configuration, we can process parts up to 3 feet x 4 feet x 3 feet, with a weight limit of up to 400 pounds.
