LPS Series of laser system for reliable Laser Machining
A typical example of laser system integration is the LPS Series, easy to use and compact to conserve valuable floor space. Typical applications include silicon wafer coring/resizing solar cell micromachining, and cutting/drilling/grooving thin metals and ceramics for all sorts of applications including medical.
Important features of the LPS-300 system
1. Through-the-Lens Viewing:
The LPS-300 features video viewing for a magnified image of work in progress. A video camera looks through the laser focusing lens – a similar principle to an SLR camera or a rifle scope. It simplifies and speeds up the alignment of each part, facilitates high yields, and targets laser impact. But most important – it provides both sharp visual human focus and sharp laser beam focus which otherwise would be at different places because of chromatic aberration. Magnification is 60X, twenty times more powerful than opera glasses.
2. Our standard design is 3-axis which increases the versatility of the laser machine. Parts having different thicknesses can be rapidly inserted into the machine.
3. Computer Controlled Focal Point
A method of rapid and reliable control of laser spot size is by the computer driving the motorized beam expanding telescope. This works by placing the laser focus quickly at desired distances above and below the top surface of the part, which does not change the operator’s visual plane of focus so the part remains in sharp focus to the human eye.

Pulse laser welders are electronically compatible and ideal for voltage-sensitive applications. Precision automated or manual welding construction can be performed on electronic/industrial components with a high degree of accuracy while eliminating the potential hazards of heat damage or thermal stress to complex manufacturing materials.
For flat plate solar energy collectors, the aluminium sheet and copper tube is thin, traditional welding will cause irregularity in welding depth, blemish, and destroy the covering film of the collector.
The Pillow Plate (or thermo plate) consists of two steel plates, connected by laser welding. After being welded together, the plate is inflated by using water pressure. The water pressure creates a specific single or double embossed profile – the pillow plate, through which the cooling or heating medium is conducted. While the thickness and the spot pattern are determined by the design pressure.
Tailored blanks are semi-finished parts, which are typically made from sheets with different alloys, thicknesses, coatings, or material properties. After joining, these will be subjected to deep drawing or stamping.
It incorporates space-saving design and ease of use. Its high cutting speed and very low operating cost make it the most affordable system on the market. The Laser system can cut both framed and frameless stencils, without requiring any changeover. The lightweight motion system allows excellent positioning accuracy while maintaining cutting speeds that are the highest in its class.

We weld aluminum alloys, steel and titanium and resolve your high-tech welding issues. Prototype work is frequently undertaken.
Standard motors have straight plain output shafts, and need gears or actuators welding on. Laser welding is ideal for its accuracy in aligning the gear and welding it firmly in place, and the low heat input avoids damaging the motor. Cars weld front wing trim actuators and gear selector motors for various teams.
The laser spot welding is an important aspect of laser process technology application. The spot welding process is thermal conduction, i.e. the laser radiation heats the surface of work piece, and the surface heat diffuses to the interior through thermal conduction and melts the work piece by controlling the width, energy, peak power and repeating frequency of laser pulse to form specific molten pool. Because of its unique advantage, it is widely used in the process of gold and silver jewelry and welding of mini and small parts.
Laser Hybrid welding is a type of welding process that combines the principles of laser beam welding and arc welding. The combination of laser light and an electrical arc into an amalgamated welding process has existed since the 1970s, but has only recently been used in industrial applications.
