MECHASYS GMBH - Prototypes and smaller batcher in lasercutting, stamping and bending

Laser cutting or laser fine cutting of metal, we can precisely process all metallic, non-toxic materials in material thicknesses from 0.2 to 2.0 mm. With our high-precision 1kW fiber laser (Nd: YAG with a wavelength of 1064nm) in combination with highly dynamic linear drives, we can produce your laser cuts in copper and brass. Due to our extremely small focus of 0.05mm, we usually create a cutting cag/ clearance of 0.07mm, so that the most delicate contours (especially inner contours) can be realized without mechanical stress, as the processing takes place without contact. This enables high-quality and precise prototypes and small series in contract manufacturing using cutting lasers. Accuracies of +/- 0.01mm, which are required in the sealing area for plastic overmolding for complete plugs or housings. Dimensions: sheet thicknesses from 0.2 to 2.0mm, max. sheet metal of max. 1,250mm x 1,250mm.

Laser welding is a very gentle welding technique, as the heat input takes place in a locally very limited area. In this way, it is possible to reliably connect critical components with one another in a materially bonded manner, without the parts annealing. With laser welding, the two welding partners are joined together with as few gaps as possible in order to then weld them together (e.g. press-fit zones such as EloPin® puzzled at any feed or distance). The background to this is that no additional material is generally used in laser welding. Exception for build-up welding or repair welding of e.g. broken tool parts such as punches or cutting plates or injection molding tools for abrasive plastics with glass fiber filling. Materials - almost all metals: e.g. • non-ferrous metals (Cu, CuSn0.15, CuSn6, CuNiSi, ...), • titanium, • steel, stainless steel (1.4301, 1.4404, ...), • spring steel (1.4310), • electrical steel (M235, M270, NO20, NO30, ...), …

When it comes to laser marking, the following types of marking are essentially differentiated: • temper colour: in the case of stainless steels and titanium, oxygen storage in the surface, • white engraving, • deep engraving, • Color removal e.g. of anodized layers for aluminum, • Color change of plastics (usually additives required in the plastic), • foaming of plastics, • ... The advantages of laser marking are on the one hand: • longevity, • Biocompatible for and in medical technology. In addition, laser inscription is: • individually designed, • space-saving thanks to data matrix code, • consecutive numbering can be generated (serial number, date of manufacture, ...), • cheap, as e.g. there are no mask costs compared to pad printing.

Samples, prototypes and small series made of sheet metal Laser cutting, embossing and bending or punching including electroplating. Prototypes and small series - everything from a single source! We manufacture your individual sample parts, prototypes and small series mostly without any proportionate tool costs. This means that we are very flexible, efficient and cost-effective even with small quantities - in extreme cases from a quantity of 1. This is made possible by our modular bending kit. Everything from a single source: • raw sheets in stock • Laser fine cutting also from pre-punching tape using camera calibration technology • Embossing, bending, folding, pressing • Punching of functional areas • Progressive punching of medium quantities, depending on economic efficiency • Module assembly • CNC laser welding • Complete or partial electroplating by partner.

Electrical Steel: rotor and stator sheets as full service Due to the growing demand for electrical steel, we have bundled our technological resources and expanded the production of pure sheet metal blanks to complete packages in stator and rotor sheets. We are therefore able to provide you, our customers the service of complete sheet metal stacks baked, laser-welded or punched packaged in the electrical steel sector. Due to our extremely thin cutting gap of just 0.07mm - as much as the diameter of a human hair - we are able to produce the smallest contours. The extreme power density at a max. laser power of 1,000 watts enable electrical sheets based on baked varnish technology with the lowest possible edge zone melting - burr-free. Everything 100% "Made in Germany" in packaged quality - usually tolerance class T7. Usual delivery times are approx. one week for cutted sheets, 2-3 weeks for baking or welding parts. Let’s get in contact for your new e-drive, rotor or stator!

Medical technology: bone saws and blades for scissors If the cutting gap has to be aligned with the laser cutting of 0.07 mm, we are able to hear the smallest contours and thus filigree deeds for and a bone saw. What used to be lavishly packaged and wire-cut is now "simply" laser, and faster. Alternatively, we also cut blanks for blades, scissors, tweezers, other surgical instruments or medical instruments for endoscopy, dental and laboratory technology.

Do you have the idea for a new product, but don't know how you should or can implement it? We gladly support you! If you wish, let us sign a mutual nondisclosure agreement (NDA). Then we can speak openly, exchange ideas in mutual interest and together create the best possible design and the associated processes. You can see some of the products that have been implemented on the following pages. For example, modular punched cable shoes, press-fit areas in customer-specific hole spacing of the circuit board or punch feed. Or do you have the problem that you can only present handwritten sketches and no CAD data suitable for production? We can support you here too. Our team will be happy to advise you and design for you.

In terms of project management, the respective feasibility study is a matter of course. No offer without a feasibility study. -An offer implies manufacturability; this is how our process is defined! - We live from prototypes and small series. Often there is no second assignment, so there shouldn't be any unforeseen surprises. Or at least only within a manageable framework. The combination of metal and plastic composite parts makes this a challenge from time to time. But you can be sure that here we draw on a wealth of experience that we would like to share with you.

Quality engineering With the most modern measuring equipment, release parts are checked and the measurements accompanying the production are carried out. Tactile measuring devices such as calipers, micrometers and dial gauges, measuring projectors and digital measuring technology are also used. All measuring equipment is subject to the annual measuring equipment monitoring - standard for us as a 9001-certified company. Our equipment is also available for you in case of contract measurement. Extract from the measuring equipment list: • Keyence IM 6125 backlight projector • Keyence VHX measuring microscope • Mitutoyo PV 5000 measuring projector • Outside micrometer 0-25mm with electr. digital display • Mitutoyo digimatic caliper ...

Projects that have already been implemented range from the construction of a "low-cost - high efficiency" laser welding system with CNC axis control focused on customer-specific needs, handling systems, assembly concepts, modular cable shoes, small presses for individual parts (bulk) or continuous goods (stips) for less than 8,000 Euros ...
