Even in this ripe context TWIMP machines shall give an added value being the solution for semi-finished with articulated geometry working. The advanced robot motion joined with the interpolation of external axis are the advantageous way of working pieces hydroformed, deep drawn, cold-moulded,...

REFLECTIVE MATERIALS
The high-reflective materials work is increasingly becoming necessary because these metals, such as copper, aluminium, bronze, are being adopted in applications related to the electrical mobility, but not only. Other sectors, like kitchen furniture or food in general, with their lucid panels are interested by this process also as preliminary preparation of following welding actions.		Instance of a round-section lucid stainless steel piece worked..
		Instance of a cut brass sample.
VARIABLE THICKNESS
Be alternative respect mechanical working, also high-precision machining, but more affordable is a request that found a valid solution in the laser processes application. A relevant challenge is, for example, the cutting of opening in piece, whose thickness is indefinitely known along the path, obtaining anyway excellent edges and well defined sections.		Instance of a not phased helical gear (teeth position unknown).
LOW DENSITY POLYMERIC MATERIAL
The principle on which is based the cutting process is the physical phenomenon of the absorption of the energy and thus the expulsion of the melt material thanks to the high pressure blown gas (of course, simplifying very much). This process happens with great difficulty whether the material affected by the energy of the laser has low density, just like that one of the polymeric fabrics. However, the cutting of this kind of materials is really common and the advantages of the laser are immediately perceptible in view of maintenance and operator safety.		Instance of cutting of few polymeric materials different in density and thickness.

The joining on which TWIMP focused its attention is the autogenous welding. Without the filling material, in fact, the economic advantages, due to the reduced power absorption, are maximized by the resetting of purchasing and logistic costs of the filler and by the zeroing of the relative machine downtimes. Furthermore, the absence of third materials introduced in the seam avoids the chemical contamination of the structures of the metals to be joined.

In order to offer the best and most advanced welding, TWIMP avails itself of latest generation laser generators with variable BPP.

DISSIMILAR MATERIALS
The joining of different materials has been normally based on a technique traditionally using filling material (i.e. MIG or TIG). The filler could introduce a different mechanical or electrotechnical behaviour in the seam zone. The process set by TWIMP technicians, instead, proposes welding of the most common metals of the automotive industry matched together.		Instance of welding of AL6061 with DP600 and AL6061 with Cu.
ABUTTED SHAFTS
This topic is generally faced with the ordinary technology called friction-stir welding (FSW); a system that requires power, material and tim consumptions not negligible. The adoption of this technique has contributed to instilling the concept of "full penetration". In reality, being the two faces joined abutted because of their own friction, it's improper to talk about "penetration". The process developed by TWIMP team ensures important penetrations of the keyhole with mechanical performances of strength and sealing utterly comparable to those of FSW.		Instance of welding as joining of abutted cilynders (with circular section), with penetration of about 15 mm well located across the joined edges.
AESTHETIC WELDING
Laser welding is the already available way to satisfy the increasingly more stringent hygienic and aesthetic concerns pertaining metal works in kitchen furnishing and food tools industry. In these sectors, in fact, is fundamental to avoid junctions in which bacteria can collect and breed or dust may accumulate, whilst alternative joining systems that facilitate a deep and accurate cleaning are mandatory. The aesthetic is the other side of the same medal. TWIMP, in this field, has cultivated perceptible experience supporting the major manufacturers affirmed throughout the world.		Instance of thin and lucid sheet-metal welding (sinks and hoods)
COPPER PARTS
Copper is a metal whose industrial use, as assembled components, is exponentially increasing. Mobility evolution toward electrical engines is giving knowledge and meaning to the words "hairpin" and "busbar". Here, respect to other applicative context, the parameters of qualifying of the welding have to match other kind of expectations such as those electrotechincal; therefore not just strength, not only sealing, but mostly conductivity. TWIMP team worked on this topic with Universities and polytechnics to define stable and spatter-free processes.		Instance of copper strips welded in overlapping where it's appreciable an homogeneous seam without porosity and spattering

Surface treatments are normally the latest manufacturing chain steps of a product. Hardening collateral effects, thus, can represent a complication for the next operations or the cause of additional corrective operations. Hardening, although useless, with its intrinsic collateral effects can introduce risks to semi-worked or finished products subject to strict dimensional tolerances.

Hardening, necessary for the durability of the artefact, cannot be, in the modern industrial world, a process that introduces costs and quality issues fixable spending time and resources.

LOCALIZED HARDENING
By leveraging the concentrated energy of the laser it's possible to heat in a scrupulously monitored manner (both temperature and penetration) the treated metal. The process has the relevant advantage, combined with the 3D functionalities of TWIMP, of hardening contoured areas of products with articulated shapes avoiding the physiological deformation due to the thermal stress of the traditional systems.		Instance of localized hardening applied to the teeth of a gear.

Coating process itself, as well as it happens in the "3D stamping" or "additive manufacturing", needs a heat source that melt the material to be deposited. The laser, concentrated energy as definition, transforms the coating in a work precise, quick and affordable.
