Which includes Dot Peen and Scribe methods to produce dot or continuous line mark, Dot Peen means hard alloy needle tip powered by compressed air or electricity to punch the metal workpiece in high frequency, and Scribe uses hard alloy or diamond needle tip powered by compressed air to carve on workpieces. Basically, peen marking is an efficient marking method for metal with high speed and high depth for a permanent mark.Fast: to mark with same specific depth such as 0.3mm, our peen marking machine is 8~10X faster than a 100W fiber laser system;Depth: our peen marking machine offer 0.1~0.3mm depth in one pass, and able to precise repeat for deeper marks;Beautiful: our peen marking machine offer smooth mark edge and keep in primary color of metal especially by scribe, and no damage or burn on environ surfaces.

Because laser marking requires no physical contact, it produces less noise and metal debris than traditional peen marking, and can be configured to fit more complex shapes. And because there are no consumables such as marking needles, laser markers can be installed and operated at high loads for long periods of time, requiring only periodic calibration to maintain consistent marking quality and efficiency.Quiet: laser marking of metal also generates noise especially deep engraving, but this is negligible compared to the peen marking process;Accuracy: Laser marking can mark as small as 2*2mm square UDI code or 0.03mm line width characters, which is impossible for peen marking;Visibility: Using MOPA fiber or UV laser for laser annealing instead of engraving for black or other color marking on metal workpiece with high contrast.

In recent years, the use of lasers as an alternative to TIG and MIG welding for all types of metals has become a trend. Compared to TIG and MIG welding, laser welding provides a smoother and more consistent power output, is easier to automate with CNC multi-axis tables or robots, and can be used with a galvanometer welding system for ultra-precise, non-contact welding.Easy to use: extremely consistent weld quality that requires less operator skill than TIG and MIG welding;Precise: QCW or MOPA fiber laser welding system produces extremely small spots and weld marks for high-precision welding of thin sheets, films, electronic circuits and more;Easy to automate: the physical structure of laser welding is simpler than that of TIG and MIG, which facilitates the development and use of automated welding.

Laser cleaning has been used since the 1960s, but it has been popularized for industrial rust removal in the last decade. Non-contact laser cleaning is more efficient and sustainable than ultrasonic or detergent cleaning. Pulsed laser cleaners have become popular as MOPA lasers have become more affordable over the years, offering finer cleaning quality and a wider range of applications than CW cleaners.Efficiency: the high-energy laser beam vaporizes contaminants in a very short time with minimal damage to the workpiece.Non-consumable: laser cleaning can be operated without detergents or catalysts, a significant savings for high-volume industrial metal derusting.Non-contact: laser beam can remove rust, oxides, oil, grease, paint and coating at a distance, therefore suitable to clean hard-to-touch workpiece such as injection mold.
