Control & Software
Modeling Software:
Any modeling software that can generates SAT or IGES file format can be used, such as: ProE, CATIA, SolidWorks, UG, Inventor, etc. CAD software can be supplied on request to client requirements
Control Panel:
SIEMENS SINUMERIK 828D is a panel-based CNC system. CNC, PLC, Operator Panel and 6-axis drive control (standard) are integrated in one unit.
This configuration eliminates the hardware interface between the CNC circuit board and the operator panel, thus improving the system’s durability and provide ease of operation. Extra customised functions can be added by the customer. Siemens provides good customer service around the world. Most of Metlas working functions can be directly accessed and modified here on the panel.
The MetBuild software is a proprietary programming software that converts 3D CAD drawings into CNC codes that can directly drive Metlas or other AM systems to build parts. MetBuild consists of three main modules:
- WorkTable:
An User-friendly environment where a CAD file can be imported, inspected and manipulated before slicing. - 3D Slicer:
Slicing 3D geometry into a finite number of 2D layers, each filled with vector paths. - EASY LMD:
A postprocessor that generates and edits G-Codes from the Vector paths. The G/M Codes can be saved as text files and then transferred to the controller unit of an AM/Cladding machine.
The MetBuild software can be purchased along with Metlas Systems, or individually, to be used on clients’ existing Blown Powder AM/Cladding machines.

From welding of special gears for small batches of gearboxes, to rack-and-pinion steering gear, differentials, cylinder blocks, suspension arm strengthening ribs and advanced devices at the cutting edge of racing technology, you can depend on us to keep your team in pole position. 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.
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 destroying the covering film of the collector.
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.
We manufacture & supply an excellent assortment of our Glove Box Welding Machines, which is widely accepted by our clients all across the globe. Our such range is fabricated from high grade material that makes it more reliable and durable. These machines are very efficient as they are built using advanced technology.
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 is 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 makes the most affordable system on the market. The Lasersystem can cut both framed and frameless stencils, without requiring any changeover. The light weight motion system allows excellent positioning accuracy while maintaining cutting speeds that are the highest in its class.
