What Is Overlay on a Cabinet Hinge

The Definition of a Coating

A coating is a covering that coats the surface of cabinet hinges. It’s applied following hinge manufacturing via various processes for purposes of protecting the base material, enhancing function, and giving the product a high-end touch.

Purpose of the Coating

Protection from Corrosion and Rust

In humid and smoky kitchens, a good coating effectively protects the hinge from water and chemical attacks.

Abrasion and Scratch Resistance

Cabinet doors are constantly opened and closed, and the coating protects against scratches and hinge surface damage.

Enhanced Aesthetics

Different finishes can create matte, glossy, or metallic finishes, which enhance the high-end look of the cabinet.

Noise-Free Experience

Certain special coatings even dampen opening and closing noise, making the hinge kinder to the hand.

Hinge Materials and Typical Surface Treatments

Typical Hinge Materials

Stainless Steel: Corrosion- and wear-resistant, and long-lasting, stainless steel 304 is the preferred option for cabinet hinges.
Zinc Alloy: Inexpensive, yet lesser corrosion resistance than stainless steel.
Iron: Low cost, but rust susceptible and short lifespan.
Aluminum alloy: Lightweight and high strength, used in minimalist designs of today.
Nylon: High elasticity, abrasion resistance, and soundness, but low strength.

Surface Treatments Common to Many Materials

Electroplating: Zinc, nickel, or chrome plating provides superior protection against corrosion and rust.
Painting/Powder Coating: Brighter color, more aesthetically pleasing appearance, and improved wear resistance.
Passivation: Forms an oxide coating on the surface of the stainless steel, providing improved corrosion resistance.
Polishing: Creates a smoother, more desirable finish and improved coating adhesion.
TNCE Flash Protective Coating: A high-tech coating that maintains hinge surface integrity in harsh, high-temperature, humid, and chemical environments. It showed high corrosion resistance after 200 hours of NSS (neutral salt spray) and 24 hours of AASS (acetic acid salt spray) tests. The technology has seen high-quality applications such as aerospace, chemical engineering, metallurgy, and shipbuilding, providing outstanding, long-lasting protection to cabinet hinges.

How do I choose and maintain hinges?

Choose materials based on the cabinet climate: Use stainless steel hinges in kitchens with high humidity to prevent rust.
Observe the quality of the coating: A good coating, in addition to affecting life, will also affect touch and appearance.
Clean periodically: Do not allow oil and grime to build up in order to reduce corrosion risk.
Avoid harsh alkalines and acids: These ruin the coating and shorten the life of the coating.

Conclusion: Make cabinets more “gentle” to use

Cabinet hinge coating is not just protective coating; it guards the user experience. From wear-and-tear and rust-proof to quiet and attractive, it adds classy, durable, and secure experience to everyday use. Accurate material selection and reliable surface treatment provide smooth and easy opening and closing in the kitchen.
