Everything You Need to Know About Electroless Nickel Plating

What is electroless nickel plating of metal substrate? How does electroless nickel plating process work? How is it better than electroplating? These are most common questions asked by the manufacturers. Let’s find the answer to these frequently asked queries.

Electroless Nickel Plating

Electroless nickel plating is the process of depositing the layer of nickel on the metal substrate by chemical reaction. As the name suggests, electricity is not used in the plating process ( www.sun-glo/electroless-nickel ). A protective layer of nickel is applied to the metal substrate via a chemical reaction.

Electroless nickel plating is used for the metal finishing of industrial machinery metal parts, tools, equipment, household metal items, and various industrial metal parts.

How does electroless nickel plating process work?

In this process, the nickel coating is plated on the metal substrate without using electricity. It is a four-step process.

1. First of all, the metal substrate underwent a pretreatment process and cleaned thoroughly. It is necessary because any sort of contaminants, soil, dirt, and foreign particles will prevent the nickel plating from adhering to the surface of the metal substrate. The metal substrate is cleaned with serious of chemicals to remove grease, oil, and dirt from the surface.

2. After the thorough cleaning, the metal substrate is activated using an acid solution. The metal part is submerged into the acid solution to remove the scale and rust on the surface of the metal.

3. Once your metal substrate is ready for the electroless nickel plating, it is submerged into the bath containing nickel ions and various other chemicals. The metal substrate reacts with the electrolytic solution, and a uniform layer of nickel gets deposited on the metal substrate. The dipping time, temperature of the bath and special chemicals used in bath depend on the type of metal.

4. The last step is rinsing the metal part with water to remove any surface contaminants and drying the metal substrate.

Advantages of Electroless Nickel Plating

Electroless nickel plating offers a wide range of benefits. Here are the few of them:

• It forms a coating of uniform thickness over the entire surface of the substrate which is difficult to achieve with electroplating. This improves the corrosion resistance of the entire workpiece and makes nickel coating more durable.

• It is less porous coating than the electroplated nickel hence provides better protection to metal substrate against wear, abrasion, and corrosion.

• Complex workpieces can be coated evenly and consistently with electroless nickel plating which is difficult to coat with electroplated coatings ( https://www.sun-glo.com/blog/ ). It can coat almost anything no matter how complex is the shape of the metal substrate.

• Due to non-porous nature, electroless nickel plating is highly resistant to water, and provide great protection against moisture.

• As no electricity is required in the electroless nickel plating, it is more accurate and cost-effective than electroplating.

This was the complete guide on electroless nickel plating.

All You Need to Know About Powder Coating

Powder coating is the process of deposition of the polymer resin on the surface of the substrate. The polymer resin is sprayed electrostatically on the electrically ground metal substrate ( www.sun-glo.com/powder-coating-services ). It is a dry process of metal coating. It can be used for the decorative and protective coating of the metal parts used in the industry as well as in domestic use. Hence, when it comes to the coating of metal parts, powder coating is the best in business.

How does Powder Coating work?

Powder coating on the metal workpiece is achieved by the electrostatic deposition of powder on the electrically grounded surface of the metal. First of all polymer resin is powdered and mixed with pigments, and then this mixture is sprayed using an electric gun. This process is called electrostatic spray deposition.

After spraying the powder, the metal surface is heated in the oven to cure. This allows the polymer resin to produce long molecular chains which are highly durable. Heating allows powder to fuse firmly on the surface of the substrate. Hence this process results into the uniform layer of powder coating on the surface of the substrate.

Advantages of Powder Coating

Powder coating services have been used in the metal finishing industry for many years. It offers numerous advantages. Let’s have a look at the key advantages of powder coating.

Last Long

Powder coating is highly durable. It does not crack or chip away easily and highly corrosion resistant. High resistance against moisture and abrasion makes it last longer. The thickness of powder coating is four to ten times more than the wet paint. This makes it tougher and better protects the substrate. Whether you are using it for the finishing of industrial metal parts or domestic metal products, it can provide uniform and highly-durable finish.

Decorative Finishing

Powder coating is not only about protective finishing, but it also provides great decorative finishing to a metal surface. It gives the metal substrate a vibrant finishing that looks really beautiful. Also, it is available in a multitude of colors. You can choose any color of finishing you want. Also, colors of powder-coated surface do not fade away easily.

Environment-friendly and Safe

This is a major reason behind encouraging the use of powder coating services. Powder coating does not protect metal parts ( https://www.sun-glo.com/blog/ ) at the cost of environment. It does not use solvents or release volatile organic compounds which cause harm to manufacturer and environment. It is an environment-friendly process. Also, unlike wet paint, powder coating is inflammable and provides extra safety to consumers.

Final Thoughts

Powder coating is tough, durable and looks great. If you are looking for the high-quality finishing for you metal parts, powder coating is one of the best metal finishing methods you have. More importantly, hiring a powder coating services can easily fit in your already strained budget.

Uniqueness of Electroless Nickel plating Over Electrolytic

Nickel is amongst the most versatile metals universally employed for plating applications. With silver while color and attributes of being malleable and anti-corrosive, its coating can be applied on objects through a long-established electroplating process ( www.sun-glo.com/electroless-nickel ) with a backup of electric current while the second option is an electroless process where deposition takes place via autocatalytic reaction. Even though both procedures are used for metal finishing, however, electroless nickel plating has been proved to be more consistent to deal with any kind of substrates, how complex it is.

The uniqueness of electroless plating mechanism makes it widely applicable since it can be used for both conductive and non-conductive objects, which is a major limitation of traditional electrolytic nickel plating. When it comes to finishing of complex metal parts having unevenness, variable thicknesses as well as holes, managing them with the desired level of finishing with electrolytic plating is hard to achieve. Remarkably, with the appearance of electroless nickel finishing, now industries have been blessed to offer their clients with the electroless advantage of consistent thickness that, no way fears of the surface intricacy or current flow troubles. It can effectively reach even the hidden parts of surfaces, for example, bearing, and produce most standardize nickel coverage throughout the parts critical for its protection.

The Electroless Nickel Plating Process

Typically, the electroless nickel plating procedure entails the use of hypophosphite solution and nickel salt for washing the base material. It also needs the essential presence of some other compounds in the solution that helps control its pH levels while stabilizing the process. As dipped into the solution, the object acts similar to a catalyst and promotes deposition of nickel-phosphorous alloy over the substrate. Electroless nickel plating is often called as autocatalytic process since it plays the role of catalytic. The unique advantage of electroless plating can be brilliantly utilized by specialized plating companies that have skilled workforce to tailor the plating bath and overall chemistry to perfectly go with the nature of the metal object and get precise nickel plating with thickness and characters you’re in need of.

Electroless Nickel Plating-Key Benefits

Enhanced Corrosion Resistance

For applications where rust resistance is a key criterion, always think of electroless nickel to fetch the highest class of corrosion protective layer of the metals. Electroless nickel solution is, in essence, a liquid mix of nickel and phosphorous whereas phosphorous is the element that results in enhanced corrosion resistance. On the contrary, while requiring 99% pure nickel solution for plating, traditional electroplating needs cannot reach the level of the anti-corrosive property.

Uniform Coating Distribution

If you produce metal components featuring deep channels, buried surfaces, holes and other complex configurations, then the application of electroless nickel plating is your ideal choice. Opposed to traditional electrolytic process, the autocatalytic reaction of the nickel-phosphorous coating can stick to all complex substrates with better reach.

Control Coating Density

Depending on the amount of coating density your product needs, electroless nickel boasts greater flexibility to determine and control the density of the metal coating. Simply by changing the amount of phosphorous to be mixed, the desired thickness can be well achieved. The thumb rule is the lower the phosphorous mix, the higher the density of your coating.

Enhanced Surface Hardness

If you’re in need of extremely durable, robust, and protective product coating ( https://www.sun-glo.com/blog/ ), electroless nickel plating can produce your satisfying level of product layer. Apart from being rust resistive, electroless high class of hard-wearing surface property protective to abrasion, wear, and friction.

Swiss Machine- A Beginner’s Guide

But still, there are a lot of aspects in which CNC machine lacks ( sun-glo.com/Swiss-Machining ), and those are taken care very well by their Swiss counterparts. Yes, we are talking about the Swiss machine.

Swiss Lathe, Swiss screw machine, Swiss automatic lathes, or Swiss turning centers are the different name of the Swiss machine. Swiss lathe is used to produce fine parts with more accuracy and less downtime that allows you to keep production on track.

So, what actually the Swiss machine is, how it is different from the CNC machine and how it works?

Let’s find an answer to these queries.

In simple words, the Swiss machine is a type of lathe where the holding mechanism is recessed behind the guide bushing. In Swiss machine, holding mechanism or collet that hold the bar stock, will not be directly exposed to the lathe bed and the tooling. Instead of this, it utilizes guide bushing for additional support.

Guide bushing offers additional support to the stock material when the part is machined. The guide bushing is fitted closely to surround the bar-stock material.

What makes Swiss machine different from CNC machine is, that in Swiss lathe headstock moves whereas in CNC machine it is fixed. In a traditional lathe, the headstock is fixed, and a workpiece is held in the collet and extends into the machine enclosure as a cantilever. A workpiece can also be supported on the end by tailstock.

On the other hand, in Swiss machine headstock is not fixed. Bar stock is passed through the chucking collet in the headstock which clamps onto it. Guide bushing emerges the bar to the tooling area and holds it radially while machining. Then the headstock starts working on the bar. It moves in back and forth in z-axis while taking the bar along with it.

Guide bushing offers rigidity to the turned parts because the very small amount of stock is exposed once it left the bushing. Swiss machines hold a better tolerance on the turning parts. Turning tools that are carried on the gang slides contact the bar closer to the guide bushing. The motion of the bar is responsible for providing the feed for this cutting section. Gang slides carry holders for tools or may support the live tooling as well.

So, this is brief about the Swiss machine and how it works. The working mechanism of the Swiss lathe is different than the conventional lathe ( https://www.sun-glo.com/blog/ ), but it offers a wide range of advantages over conventional lathes.

Hence, if you are planning for installing a CNC unit in the factory, then the Swiss machine seems to be a sensible choice taking into account the production.
