Laser Structuring Makes Plastics Shine

Kunststofftechnik Bernt (KTB) has developed a new day‐night design for decorative panels in car interiors. The design can produce colored light using laser technology passing through chrome‐plated plastics. The system manufacturer Acsys Lasertechnik has delivered two laser systems and supporting KTB in technology development.

Fast Laser Beam Characterization

The power‐to‐weight ratio plays a key role in automotive construction: the lighter the powertrain components of the car or truck, the more efficient the vehicle. Moreover, it significantly cuts emissions and fuel consumption. And engineers are always striving to eliminate parts that are at higher risk of wear and tear. With these goals in mind, automotive experts at Daimler have successfully optimized the design and…

Beam Shaping

Using Diffractive Optical Elements

A diffractive optical element (DOE) uses thin micro‐structure patterns to alter the phase of the light that is propagated through it. Those micro‐structures, once properly designed, can manipulate the light to almost any desired intensity profile or shape. This technology enables many functions and light manipulations which are not feasible with standard refractive optics. In many applications, these…

Laser Cutting

Integrated Pierce Detection in Fiber Lasers

Piercing is a necessary but time consuming step in sheet metal cutting, particularly in thicker materials. Knowing exactly when pierce through is achieved is key to cutting efficiency, by eliminating wasted dwell time. Pierce detection has been a high priced optional extra on top end cutting process head but its uptake has to date been limited. SPI Lasers has developed a novel sensor within the laser that looks at back…

Laser Cutting, Positioning, and Joining in One Clamping

Equipping components which carry media with threaded bushings or fittings, replacing hydroformed components by deep‐drawn half‐shells, and building complex 3D assemblies from individual parts direct from the coil – these are the areas of application for CutFusion from Weil Engineering, the mechanical engineers from Müllheim, South Germany. CutFusion not only saves a great deal of handling time and effort, it also makes the…

Laser Welding

Seeing Things in a New Light

Nuburu has introduced a new high‐power blue laser that brings unmatched performance to many materials processing applications. Lasers are capable of delivering high energy density with pinpoint precision. The energy can be delivered without physical contact between the components of the laser and any material to be worked. These characteristics suit lasers for many materials processing applications – perhaps none more…

Additive Manufacturing

Hot Lithography – New Possibilities in Polymer 3D Printing

Additive manufacturing as an industrial production tool of polymer parts requires outstanding precision and surface quality of the printed objects in combination with good mechanical and thermal material properties. For this, current technologies often provide only insufficient solutions. Cubicure developed the hot lithography technology which allows the processing of high‐performance photopolymers in outstanding…

Application Report

3D‐Printed Sewer Cleaning Nozzles

It takes four steps to make a conventional sewer cleaning nozzle – cut, turn, mill, and glue the material. Trumpf recently joined forces with the nozzle manufacturer USB Düsen and the Heilbronn University of Applied Sciences to expedite the process with additive manufacturing (AM) and optimize the components. Their efforts paid off: USB Düsen’s machine availability is up 53 percent and the water jet’s guidance has improved….
