High energy density enables precise processing of thick metal plates

Fiber lasers are utilized for a broad range of material processing from metal to polymer. Spot size narrowed down by focusing high quality beam brings more energy density to faster high-precision cutting. High power kilowatt-level fiber lasers grow in the plate thickness for practically feasible cutting thus responding to broader processing needs.

Excellent welding quality beyond expectation

Fiber lasers possibly defy the common wisdom in the past by realizing excellent quality welding. The additional power and better beam quality decrease gap of target materials and provide cleaner welding lines and faster speeds. Single fiber laser welder is able to cover various processing needs so as to decrease the number of operation processes. High power feature enables faster processing so as to improve production throughputs. Lower cost of ownership in comparison to older solid-state laser technology should not be overlooked.

Contributes to electronic device waterproofness, automobile weight reduction, etc.

Laser plastic welding is a processing method that uses laser irradiation to adhere targets by generating heat at the boundary surface. Combination of laser permeating material and laser absorbing material is required to implement the processes. Not only will plastic welding enable draft-free, high velocity joints, but also adhesions that have been difficult for existing methods to realize.

Innovation of unconstrained material selection

Fiber laser marking covers semi-permanent engraving on variety of materials such as metal, non-metal, ceramics, plastic, glass, silicon-materials etc. One of the features of fiber laser marking is microfabrication which enables engraving within ultra narrow space. As a non-contact marking method, fiber lasers are also utilized in medical and food sectors. Fiber lasers are more flexible than other lasers in terms of peak power, nanosecond pulses, frequency and process speed, which allows for effective marking and engraving by choosing optimal process conditions applicable to the target material. Additionally, fiber lasers are both color pigment-free and solvent-free, making it an ecological marking method.
