Industry Applications

Color-Coding

Two springs dyed different colors with Carco Dyes

Carco manufactures over 200+ different formulations and 20+ colors that can be used for color coding and dying springs for customer requirements. Whether you need a simple identification stripe or an entire spring coated, Carco has the solution for you.

Identification Striping

Our part marking solutions can seamlessly integrate with your in-line wire marking machine, providing an immediate-drying stripe or quick-drying line to your wires and spring products to indicate tensile strength, material composition, and other important characteristics. This precise identification ensures quality control and operational safety, especially in high-stress environments or critical applications.

Our Solutions

Our non-contact ES-800 Series Spray System is  ideal for high-speed applications and other applications requiring a small, controlled spot. It is compatible with fast-dry marking fluids and has 3” or 6” extensions for tight-fitting areas.

Carco’s ES-1010 Low-Pressure Spray System operates between 5 and 15 PSI to reduce overspray in continual marking applications.

Pigmented Inks

We carry many long-lasting pigmented inks with fantastic print quality and color stability, including the MM-150 and F-123.

Our MM-150 pigmented ink has fair alkaline wash resistance, excellent adhesion on both porous and non-porous wires and springs, and is available in multiple colors, including black and red. Dry time is between 25 seconds to one minute.

Our F-123 pigmented ink has a longer drying time of about three minutes compared to our MM-150 ink (25 seconds to one minute), but it’s ideal for open pad wire and spring stamping. The F-123 comes in multiple colors, including red, blue, brown, and black.

Dye Type Inks

Our dye type inks are ideal for bright metal wires and springs. With good flowability, these inks won’t plug or clog, ensuring a steady marking stream. They are good inks for low-volume or low-throughput marking.

For wire and spring marking, we recommend our 1000-I dye type ink. It’s quick drying (25 seconds to one minute), non-settling, and provides good adhesion on porous and non-porous materials. It’s also available in eight colors, including red and magenta.
