What’s Part Marking Process?

Part-marking is a crucial manufacturing process involving applying unique identifiers, such as codes, symbols, or labels, onto components or products. This practice serves multiple purposes across industries, including traceability, inventory management, quality control, and regulatory compliance.

By marking each part, manufacturers can monitor and track the item’s journey throughout its lifecycle, enabling easy identification during recalls, maintenance, or warranty claims. The part-marking process utilizes techniques such as laser engraving, dot peen marking, chemical etching, and RFID tagging. The method selected is influenced by factors such as the part’s material, size, and durability criteria.

Laser engraving, for instance, offers high precision on metals, plastics, and ceramics, while dot peen marking excels in direct and durable engraving. Customized part marking also significantly influences brand protection, anti-counterfeiting efforts, and meeting industry regulations. It fosters transparency in the supply chain and helps prevent subpar or counterfeit parts from infiltrating the market.

Consulting a marking expert is vital to ascertain the most suitable material for specific part marking applications, ensuring optimal results.

  • Stainless Steel
  • Aluminum
  • Copper
  • Carbon Steel

Stainless Steel - Steel

Stainless steel is metal-enriched with chromium elements (11%) and a small amount of carbon. Chromium offers corrosion resistance to stainless steel. Due to this, the die-cast parts are less likely to be affected by rust or corrosion. It can be easily molded into several forms. Thus, manufacturers prefer it for the die-casting process.


  • Extremely durable
  • High tensile strength
  • Corrosion resistant
  • Easy fabrication and formability
  • Low maintenance cost


The distinctive characteristics of aluminum make it one of the best materials for die-casting. The major aluminum alloys are A360, A380, A390, A413, ADC12, and ADC1. Among all, the A380 is the most worthwhile aluminum alloy.


  • Excellent corrosion resistance
  • Lightweight
  • High strength and hardness
  • Outstanding thermal conductivity
  • High electrical conductivity
  • Remarkable EMI and RFI shielding properties



Copper is a reddish-orange metal with a face-centered cubic structure that is highly valued for its aesthetics. It exhibits remarkable properties, yet, it can be alloyed with different elements, such as aluminum, tin, zinc, nickel, etc., to improve its characteristics further. The following are some fundamental properties of copper that make it ideal for producing die-casting parts.


  • Very soft
  • An excellent conductor of heat and electricity
  • Good corrosion resistance
  • High ductility
  • Fine malleability


Carbon Steel - Steel

Carbon steel is famous for its low cost and versatile nature. Typically, carbon steel is divided into three categories, i.e., low-carbon, medium-carbon, and high-carbon steel. The properties of these types differ according to the carbon content present in the material. Low-carbon steel is known for its good machinability and weldability, whereas high-carbon steel is used in high-strength applications.


  • Very hard
  • Ductile and malleable
  • Relatively low tensile strength
  • Good machinability
  • Low cost

Surface Treatment For Part Marking Parts

Our techniques, such as coatings and polishing, ensure lasting quality, safeguarding markings from wear and environmental factors. This meticulous treatment adds value and reliability to your marked parts.



Anodizing -

Anodizing improves corrosion resistance, enhancing wear and hardness and protecting the metal surface. This surface finish is widely used in mechanical parts, aircraft, automobile parts, and precision instruments.

Aluminum, Magnesium, Titanium, Zinc

Bead Blasting

Bead Blasting -

Bead blasting in surface treatment is a process where fine abrasive particles, such as glass beads or ceramic media, are propelled at high speed onto a surface using compressed air. This abrasive action helps to remove rust, paint, or other contaminants, leaving behind a clean and textured surface finish.

ABS, Aluminum, Brass, Stainless Steel, Steel


Smooth, Matte finish

Powder Coating

Powder Coating -

Powder coating in surface treatment is a dry finishing process where a fine powder is electrostatically applied to a surface. The coated object is then cured under heat, melting the powder particles and forming a durable, smooth, uniform coating.
