Laser Ink Bonding (LIB)
High-Contrast, Permanently Fused Markings for Technical Polymers
What is Laser Ink Bonding?
Laser Ink Bonding (LIB) is a specialized surface-marking process designed to create rich, high-contrast, permanent marks on hard-to-mark engineering plastics—including Delrin (POM), HDPE, Polypropylene, and UHMW-PE—without causing surface erosion or thermal damage. Think of it as tattooing the material: an energy-absorbing ink layer acts as the pigment, and a precision laser beam acts as the needle, permanently driving and embedding that pigment directly into the surface skin of the substrate.
During processing, the temporary ink coat captures the laser's optical energy and translates it into controlled, localized heat. This momentary thermal action fuses the dark pigment into the micro-surface layer of the polymer. Once rinsed, any unreacted surface ink washes away cleanly, leaving behind a sharp, durable mark locked within the plastic itself.
Key Advantages
High Contrast on Difficult Resins: Produces dark, high-density logos, serial numbers, and 2D barcodes on natural, white, and translucent plastics.
Surface-Flat Integrity: The mark resides flush within the polymer surface, preserving the part's original physical dimensions and surface finish.
Non-Destructive Process: Localizes heat to the outer micro-skin, preventing the foaming, scorching, or surface warping common with direct laser engraving.
Durable & Wear-Resistant: Because the pigment becomes locked into the plastic matrix, the resulting mark resists friction, moisture, and common shop chemical solvents.
Material Compatibility
LIB is optimized for low-surface-energy and technical thermoplastics:
Others: We will test any material to see if it will work
