Heat treating
Heat treating is a process that involves heating and cooling metals to alter their physical and mechanical properties. This process is commonly used for steel items to improve their hardness, strength, and ductility.
There are several types of heat treating techniques:
- Quenching: Involves rapid cooling of the metal to increase its hardness.
- Annealing: Involves heating the metal and then allowing it to slowly cool, resulting in increased ductility and reduced hardness.
- Tempering: Involves reheating the metal after quenching to reduce brittleness and increase toughness.
- Solutioning: Involves heating the metal to dissolve solute atoms into the solid solution, followed by rapid cooling to trap the solute atoms in the solid solution.
- Heat hardening: Involves heating the metal to a high temperature and then cooling it slowly to increase its hardness and strength.
- Stress relieving: Involves heating the metal to reduce internal stresses that may have been introduced during other manufacturing processes.
Overall, heat treating is essential in the manufacturing industry to improve the performance and durability of metal components.
Sulfation
Sulfation is a chemical process that involves the treatment of metals to improve their sliding properties and corrosion resistance. This process helps to extend the service life of tools by making them more durable and resistant to wear and tear.
Siliconising
Siliconising increases metal resistance to high temperatures and acids by heating metal elements using powdered ferrosilicon or a gaseous environment saturated with silicon and chlorine compounds.
This process forms a protective silicon layer on the surface of the metal, providing enhanced durability and corrosion resistance. Siliconised metals are commonly used in various industrial applications where exposure to extreme conditions is expected.
Welding
Welding joins metals by melting and solidifying them through various methods like manual metal arc welding, tungsten inert gas welding, and welding with a consumable electrode.

Metal finishing is crucial for improving durability, appearance, and corrosion resistance. At Manufacturing Solutions Inc. (MSI), we provide various metal finishing techniques for industries like aerospace, defense, and energy.
Basic methods of metal processing
Primary metalworking methods like machining, metal pressure treatment, welding, and casting can be used individually or combined to achieve specific outcomes.
Mechanical (milling) processing of metals
Mechanical processing involves shaping metals by removing material using cutting tools such as drills, lathes, and milling machines. This method is commonly used for creating precise shapes and patterns on metal surfaces.
Machining of metals under pressure
Metal pressure treatment methods involve applying force to deform metal into the desired shape. Processes like pressing, rolling, drawing, and forging are used to create complex shapes and structures in industries like mechanical engineering, automotive, and aviation.
Welding
Welding is a method of joining metals together by melting and fusing them. This process is commonly used in construction, manufacturing, and repair work to create strong and durable metal structures.
Casting
Casting is a metal processing method that involves pouring molten metal into a mold to create a specific shape once it solidifies. This method is commonly used in the production of complex and intricate metal parts for various industries.
Metal finishing techniques enhance metal surface quality, durability, and aesthetics. Methods like electroplating, passivation, and powder coating are commonly used to provide a protective layer, improve corrosion resistance, and enhance the appearance of metal surfaces.
Adding and Altering Metal Finishing Processes
Metal finishing techniques add, alter, or remove finishes based on product requirements. Processes like electroplating, passivation, and powder coating are widely employed.
Types of Metal Finishing Techniques
Choosing the right finish is essential for product function, material, and aesthetics. Understanding various metal finishing techniques helps save time and resources.
Electroplating
Electroless Plating
Passivation
Passivation is a chemical treatment for stainless steel and other metal alloys, providing corrosion resistance without altering appearance.
Benefits of passivation include:
- Increased corrosion resistance
- Reduced maintenance
- Removed contamination
Hot Blackening
Hot blackening applies a black oxide coating to metal surfaces using tanks with cleaning agents, coolants, and materials for smaller parts.
To enhance durability and achieve a matte appearance, manufacturers utilize hot blackening for automotive parts, firearms, and military applications.
Powder Coating (Available In-House at MSI)
Another method, powder coating, involves applying a dry powder containing pigments and curatives onto a substrate through an electrostatic process. This powder is then heated to create a resilient finish that can withstand harsh weather conditions.
MSI provides in-house powder coating services with fast turnaround times and consistent quality.
Phosphate Coating (Available In-House at MSI)
For increased corrosion protection, phosphate coating is applied to steel and other metal parts. This coating forms a thin layer that can serve as a base for lubricants or other coatings such as paint or powder coating.
MSI includes phosphate coating as part of its comprehensive finishing solutions.
Removing and Reshaping Metal Finishing Processes
Various metal finishing techniques are utilized to modify the surface of a part to achieve a desired appearance. Processes like electropolishing, buff polishing, and abrasive blasting are commonly used to reshape or eliminate surface flaws.
Electropolishing
Electropolishing, for instance, eliminates metal ions to create a smooth surface, offering benefits such as improved corrosion resistance, reduced cleaning time, and removal of burrs.
Buff Polishing (Available In-House at MSI)
Alternatively, buff polishing cleans and smoothens metal surfaces without an electrochemical reaction, providing a shiny finish for metallic components.
Abrasive Blasting (Available In-House at MSI)
Abrasive blasting, which involves high-pressure propulsion to clean and prepare metal surfaces, includes variations like shot blasting and sandblasting.
Advantages of abrasive blasting include the removal of contaminants, a clean finish, and preparation for plating or coating.
Additional Industrial Metal Finishing Options
In industries such as aerospace, defense, and medical, specialty processes like electropolishing, hot blackening, spray painting, and vibratory bowl finishing are commonly employed.
Choosing the Right Metal Finishing Method
When choosing a finishing method for metal parts, factors to consider include the end-use environment, material compatibility, aesthetic expectations, adhesion requirements, and regulatory compliance. MSI offers metal fabrication capabilities to support both finishing and fabrication needs.
