Explore our flagship OEM laser systems engineered for high-precision plastic marking, deep metal etching, continuous CW rust removal, and automated tube cutting. Certified under rigorous ISO 9001 quality frameworks and compliant with CE safety standards.
In modern high-speed production environments across medical device manufacturing, automotive electronics, aerospace component identification, and FMCG packaging, achieving permanent, high-contrast, non-destructive polymer identification presents a severe technical challenge. Traditional printing techniques involving ink-jet continuous coders or pad printing suffer from solvent degradation, low mechanical wear resistance, and toxic chemical emissions that violate strict global environmental frameworks such as RoHS and REACH compliance.
As China's premier plastic laser marker supplier and global exporter, our engineering philosophy is built upon deep photon-material interaction research. Marking plastics with laser radiation is not a single uniform process; rather, it requires a precise match between the laser wavelength, pulse width (nanosecond, picosecond, or femtosecond regime), and the chemical composition of the host polymer—including organic additives, flame retardants, color pigments, and laser-direct-structuring (LDS) dopants.
When a laser beam impacts a plastic substrate, two distinct physical mechanisms govern color change and mark formation:
Utilizing Infrared wavelengths (1064nm MOPA Fiber or 10.6µm CO2 lasers), thermal energy is rapidly absorbed by the plastic matrix. In light-colored thermoplastics, controlled thermal degradation causes local thermal expansion, generating micro-bubbles within the polymer melt—a phenomenon known as Foaming, yielding a raised light-colored mark on dark substrates. Conversely, on light substrates, local heating carbonizes organic molecules to create dark, indelible characters.
Ultraviolet (UV) laser light operates at a short wavelength of 355nm, carrying high photon energy capable of breaking chemical molecular bonds directly without generating macroscopic thermal energy. This process—known as photochemical bond breaking—enables damage-free marking on heat-sensitive polymers such as HDPE, PEEK, PTFE, and delicate silicones without micro-cracking, melting edges, or altering structural integrity.
Select the optimal laser wavelength, power output, and optical scanner setup based on your exact engineering plastic formulation:
| Plastic Resin Type | Common Substrates | Optimal Laser Source | Dominant Mechanism | Mark Quality & Contrast |
|---|---|---|---|---|
| ABS / PC Blends | Automotive Trim, Enclosures | MOPA Fiber (1064nm) / UV (355nm) | Photothermal Carbonization / Photo-bond | Extreme contrast black mark; crisp edge definition. |
| PE / Polypropylene (PP) | Bottle Caps, Piping, Containers | 355nm UV Cold Laser / Additive Fiber | Photochemical Color Change | Pure white or dark mark without micro-foaming surface roughness. |
| Polyethylene Terephthalate (PET) | Beverage Packaging, Thin Films | 355nm UV Laser / 9.3µm CO2 | Photochemical Bond Dissociation | High-clarity, non-penetrating laser coding; zero structural puncture. |
| PEEK & Medical Silicone | Surgical Implants, Catheters | Picosecond UV (355nm) | Pure Cold Photo-ablation | Biocompatible, zero-heat marking compliant with UDI sterilization. |
| Polyamide (Nylon 66 + GF) | Connectors, Engine Compartments | MOPA Fiber with Variable Pulse | Additive-assisted Thermal Alteration | Highly legible white/grey characters on glass-filled black resin. |
As global supply chains transition toward Industry 4.0 digitisation and ultra-sustainable manufacturing, procurement directors and automated systems integrators must look beyond initial hardware acquisition costs. Future-proof purchasing decisions require aligning with next-generation technological shifts:
Conventional Q-switched fiber lasers with fixed pulse duration (100ns) generate excessive thermal stress on polymers, leading to burning or melting. Modern procurement heavily favors MOPA (Master Oscillator Power Amplifier) technology, enabling independent tuning of pulse widths from 2ns to 500ns. Short pulse widths minimize thermal dissipation, allowing precise color-marking on delicate electrical connectors.
High-speed packaging and semiconductor production lines demand zero-defect quality assurance. Next-gen plastic laser markers integrate coaxial machine vision camera systems. These vision-guided lasers automatically align marking orientation on floating parts and perform instant post-mark OCR (Optical Character Recognition) and 2D DataMatrix code readability verification in real time.
Fixed focal length f-theta lenses are inadequate for complex contoured auto parts or ergonomic consumer electronics. Global buyers are prioritizing system configurations equipped with motorized 3-axis dynamic galvo scanning systems, capable of maintaining sub-millimeter spot sizes across multi-tiered surfaces, spheres, and inclined planes without mechanical axis movement.
Representing the pinnacle of Chinese laser equipment engineering, our enterprise combines world-class optical design expertise with strict European manufacturing rigor. Inspired by decades of UK and German industrial engineering standards, our facilities deliver laser systems that redefine operational longevity and precision.
Every machine undergoes a rigorous 72-hour continuous laser power stability burn-in test, galvo drift verification, and electrical safety insulation audits before international dispatch. Fully CE certified with Class 1 laser enclosure designs available.

UV 355nm lasers utilize short-wavelength light that breaks chemical bonds directly (cold processing), producing ultra-clean marks without thermal melting or charring. Fiber 1064nm lasers rely on heat (photothermal), which works excellent on certain plastics with laser additives or ABS, but can scorch heat-sensitive plastics like HDPE, thin PET, or medical-grade silicone.
Yes! Transparent plastics such as PET, clear Polycarbonate, and Acrylic do not absorb standard 1064nm infrared fiber laser wavelengths. However, they strongly absorb 355nm UV laser wavelengths or specialized CO2 9.3µm/10.6µm wavelengths, allowing permanent vector engraving or sub-surface frost marking without burning.
Laser additives—such as mica particles, antimony trioxide, or proprietary optical absorber compounds—are mixed into raw plastic resin before molding. When hit by a fiber laser, these additives absorb photon energy rapidly, triggering intense color changes (dark-on-light or light-on-dark) even in challenging resins like pure Polypropylene or Polyethylene.
Our controllers natively support standard vector and raster file formats including DXF, PLT, AI, BMP, SVG, and JPG. For smart factory integration, our systems feature TCP/IP, Modbus, and RS232 communication interfaces to seamlessly connect with factory MES/ERP systems for dynamic serial number, 2D QR code, and barcode generation.
All export-grade machines come standard with a comprehensive 2-year to 3-year warranty covering the optical laser engine, galvo scanner, and power supplies.
