Laser Ablation Plastic

Application Details:

The various HMWPE (High Molecular Weight Polyethylene) were sent in for processing with our 20 watt fiber laser. The customer’s logo was generated and lased on all the various color samples and implants using various laser parameters to achieve the best overall contrast. Some colors responded better than others due to their individual absorption rates of the 1060-1070nm wavelength produced by the fiber laser.

By comparison to an Nd:YAG producing the same wavelength, the beam structure of the fiber laser is of a much higher quality (smaller spot size, higher energy density and is round/concentric versus a significantly larger beam size that is elliptical and not nearly as uniform). Many of the colored HMWPE parts were marked at 8 watts of power resulting in approximately a 3.5 second cycle time. The remaining colors required full power to create a contrasting mark at the 3.5 second cycle time. The orange sample did not result in any contrast.

Laser Engraving Machine

Fiber Tower™ Series is the new generation of Fiber Laser Material Processing Systems for Direct Parts Marking, UID Marking (Unique Identifier), and Deep Engraving. It is the most advanced, compact, industrial grade, mid size, Fiber Laser Engraving Machine available on the market. Fiber Tower™ series employs the new generation of solid state Ytterbium fiber laser systems of near infrared spectral range (1060-1080nm) with a unique combination of high peak power, ideal beam quality, fiber delivery and highest electro-optical wall-plug efficiency

These laser machines possess a reliability that is unmatched by any other kind of solid state or gas laser systems. Wide selectivity of operating wavelengths, ultra-low amplitude noise, high stability and ultra-long pump diode lifetime complete an impressive list of advantages of these modern fiber laser systems.

Hand Held Laser Marking System

The Hand Held Fiber Laser is a safe, state-of-the-art, Direct Parts Marking (DPM) alternative for Nd:YAG and Nd:YVO4 lasers (Lamp-pumped, Side-pumped Diode, and End-Pumped Diode). Components include a Q-Switched Ytterbium Fiber Laser with Scan Head, Industrial PC Controller, Power Supply, and Marking Software.

Direct Parts Marking, UID Marking, Date Codes, Bar Codes, Time Stamps and all other permanent marks on all non-movable parts and equipment for traceability and Code Compliance purposes.

Fiber Laser Marking Kit

The i-Series Fiber Laser Marking Kit was specifically designed for maintenance-free OEM applications.  It delivers a diffraction limited (M2<1.05) laser beam directly to the worksite via a metal sheathed single mode fiber cable.

These compact service-free lasers are designed to operate under high shock, vibration and dust conditions, with relatively high humidity and temperatures. They do not require routine replacement parts or materials. Wall-plug efficiencies up to 50% result in a compact size, reduced utilities, and trouble-free air cooling.

Fiber-to-fiber architecture means a robust, monolithic design with no optics to align or maintain, no mechanics to stabilize, and with the focusable power and high power densities needed for the most demanding applications. One cable connection makes it easy to integrate into any laser marking and engraving system.
