In Losma, we have the necessary cutting equipments to cover any need of our customers. All the laser models have been acquired with criteria of quality and efficiency, and include all the technological advances to guarantee a fast, precise and a maximum quality production.
The maximum cutting dimensions are 3000 x 1500 mm, with a maximum thickness of 25 mm in steel, 20 mm in stainless steel and 12 mm in aluminum.
The precision of our equipment allows us to work with tolerances of less than 0.1 mm, which guarantees maximum precision in all measures.
We work only with high quality materials, always guaranteed and certified by local suppliers of maximum confidence. We have immediate availability of the most common materials and thicknesses used by our customers, while the materials and special thicknesses are provided on demand according to your needs.
The laser cutting is a procedure of thermal division for the treatment of metal sheets. The laser beam is generated in the source or resonator, and it's guided with a mirror towards the nozzle of the head, where a lens concentrates a ray of very small and powerful diameter on the sheet, which melts the material.
This technology offers important advantages in the treatment and processing of metal sheets:
In CO2 lasers, a gas mixture generates the beam to the resonator by means of semiconductor exciter modules that are free from wear. It is the most suitable technology for universal use in different materials and thicknesses.
The cutting is done by fusion and sublimation, using high pressure gas to remove the remains of molten material from the cutting area. First, the starting point of the cut is heated to the melting point, then a jet of gas removes the melt from the edge by sublimation, avoiding the need to raise the temperature of the material.
We have several folding press breaks, all operated by numerical control highly by trained and experienced professionals. The equipments software allows the automation of processes for large series, which achieve to reduce the unproductive times and thus reduce costs, which allows us to impact the saving on the final price. The maximum folding dimensions are 4 meters of length and 12 mm of thickness. (In the case of large thicknesses, the maximum length may be reduced).
The needs of our customers are a priority for us. For this reason, we have specific folding tools manufactured in-house for special configurations. Flattening of double edges, round vertices, closed angles or protection against marks, are usual requirements in our daily work. Ask us what you need and we will provide you with personalized advice from the most experienced professionals in the sector.
These are machines specially designed for folding metal sheets. The force is transmitted vertically from two hydraulic pistons to the punching tool, which inlays the sheet into the matrix, to the exact point of folding required by the type of workpiece configuration.
The numerical control allows a high degree of automation, as well as an unbeatable precision in sizes and folding angles.
The software allows computers to program any bending sequence automatically, making production more accurate, and a faster and more efficient series production.
We have welding equipment for any material and need. Electrode (SMAW), continuous wire (GMAW), points (resistance, ERW) or gas (blowtorches).
In addition, our facilities are prepared to work in the most efficient way, regardless of the measurements and configuration of your product.
Our welders have a vast experience of more than 30 years. This allows us to guarantee results and finishes of the best quality for any type of product, whatever its difficulty or specificity.
Welding is a fastening procedure whereby two or more pieces are bonded together. The parts are fused by adding a filler, which has a lower melting point than the material of the pieces, which upon cooling becomes a strong bond. To form the joint between two pieces of metal, an electric arc is usually used. Fusion welds are generally made by direct contact with a tool or hot gas.
SMAW (electrode): It is a manual process that uses a permanent tungsten electrode, an inert gas and a filler material. It is characterized by a stable arc and a high quality weld. Requires highly qualified staff
GMAW (wire): This method is similar to the previous one, but the electrode is continuous and consumable. It is characterized by its balance between speed and quality.
Resistència (by points, ERW): it consists of passing an electric current of great intensity through the metals to be joined. Thus, there is an increase in temperature at the juncture. Taking advantage of this energy and with a little pressure, a union with almost imperceptible marks is achieved. Suitable for plates between 0.5 and 3 mm.
If you need to manufacture a specific component, but you don't have the possibility to develop it, or you are not clear about its suitability for your project, bring us your design idea. We will study it and develop it with you until it is 100% fit for your needs. We have the experience, the software and the necessary staff to ensure an optimum result in any application.
Our technical draughtsmen have developed for many years pieces for all kinds of sectors, with a demonstrable success by our clients. Their training and experience ensure great speed and efficiency in the development of custom projects.
We guarantee the maximum precision in the final result of your products, as well as an efficient use of the material, which allows us to adjust a lot the price of the series production.
Computer-Aided Design. CAD is used to design, develop and optimize products. It is also widely used in the design of tools and machinery used in the manufacture of components and the technical design of all types of constructions, from small residential type (houses) to commercial and industrial structures (hospitals and factories).
CAD has become a particularly important technology within the field of Computer Assisted Technologies, with tangible benefits, lower product development costs and very reduced design cycles.
In our company we work with standard software to the industry, Autodesk AutoCAD.
We accept, however, any vector graphics exchange file.
Libellula is a CAD / CAM application optimized for programming all types of cutting machines. Thanks to its integrated CAD system, it creates or imports files of geometric pieces from any other design environment, optimizing profiles automatically. Thanks to its excellent automatic algorithms of implantation, Libellula calculates better the positioning through a growing system of tests increasingly precise.
Libellula increases productivity in the workshop, ensuring that the amount of material actually used, meets the minimum threshold chosen by the user and optimizes the working space for any laser cutting technology.
