It is important to remember the need of selecting the right metal finishing techniques for parts among all the other considerations and decisions that go into producing a good. Though there are several kinds of metal finishing, they are all basically the same in that a layer is applied to the surface to treat the outside of the product. Every approach offers various advantages and disadvantages together with distinct outcomes.
Completed finishing for various metals gives the design the intended appearance and surface roughness. The application of a treatment can also improve thickness, strength, hardness, and longevity in addition to adding protection against tarnishing and corrosion. Many goals may be achieved in the metal finishing process, from raising electrical resistance or conductivity to increasing the possibility of vulcanization.
A List of Typical Metal Finishing Types is as follows:
- An anodized coating is produced by the electrolytic passivation process, which also increases thickness, hardness, corrosion and wear resistance.
- Anodizing: It is the process of enhancing the thickness, hardness, corrosion, and wear resistance of an anodized coating by electrolytic passivation.
- A smooth and appealing finish is achieved by blasting grains of abrasives, such as sand or beads, at a metal surface.
- Painting is covering metals mostly for aesthetic purposes and to provide surface protection. Corrosion protection in hostile settings can be had at a reasonable price with paint.
- Using an abrasive belt or wire brush, smooth away surface flaws and slightly round edges in brushed metal. The surface of the metal gets a consistent grain texture via this technique.
- Applying a layer of oxide to surfaces at high temperatures, known as hot blackening, gives them a black appearance, boosts hardness, and provides remarkable resistance to corrosion and abrasion.
- Using a cloth wheel, buff polishing removes metal from the surface to provide a very smooth and glossy finish. Its great ability to improve surface aesthetics is why it is used so frequently.
- Metal grinding is the technique of using friction, attrition, and/or compression to give hard metal surfaces different degrees of smoothness. Many times, it is used as the last stage of machining to reach a particular tolerance.
- In order to consistently polish and ready small components in high-volume production, a vibratory finishing machine cleans, descales, deburrs, and dulls sharp edges.
- Powder coating: For remarkable impact resistance, durability, and homogeneity, the powder is applied to metal electrostatically and then heated to solidify the coating.
- Passivation is a corrosion-resistant steel treatment that removes surface impurities with citric and nitric acids. Additionally aiding in the achievement of tight tolerances and maintaining the dimensional integrity of components is passivation.
Selecting Among Metal Finishing Types
Finding the right style for your project or application can be determined by looking over the many kinds of metal finishes. A few more things should be taken into account after you have reduced your options before deciding. Depending on a few factors, some finishing types might be a better choice for you than others whether you are under a time constraint or are attempting to stay inside a budget.
Think about the following while choosing the ideal metal finishing style:
Time to Production:
Businesses need a productive supply chain. You probably need metal parts sooner than later for a project or piece of equipment. Producing some metal finishings takes longer than others. Find out from the manufacturer the production time for each kind of metal finishing you’re thinking about. Finding the ideal metal finishing process with a short production time might be a terrific choice for your company if you want to keep your supply chain productive and efficient.
Hardness of Metals:
You could have to concentrate on particular finishing techniques depending on the kind of metal and its hardness. Usually, harder metals need a more robust and powerful finishing technique to make the finishing visible on the metal. Because tough methods abrasively perform better on hard metals than on soft metals, they are ideal for them.
Price of the Finishing:
The several kinds of metal polishing come at different prices. Analyze the average price of each type before investigating these types, then choose the finishing choice that fits your budget. Higher quality, quicker production, and greater versatility are features of the more expensive options, as they are of many other products. Your choice to purchase can be influenced by comparing prices between finishes you prefer and by asking the manufacturer a lot of questions about the quality of the metals.
Selecting from Metal Finishing Applications
The correct metal finishing solution for your business will be found with the help of these factors and others. Your desired finishing appearance and the properties of the metals you are working with, such as heat resistance and vulcanization potential, are further considerations.
