Hybrid technology is divided into two processes. In insert molding, plastic parts are combined with components made of different materials. In this process, metal inserts are predominantly used and usually completely overmolded with plastic. This results in a stable connection between metal and plastic. A subsequent assembly step can thus be eliminated.

GRAFE is an expert in coloring translucent plastics Decades of experience, the highest level of technical know-how and state-of-the-art technical equipment - these are the three pillars on which the comprehensive expertise of the GRAFE GROUP, Blankenhain, in the coloring of transparent engineering plastics rests. "The requirements for dispersion and homogenization are much higher for transparent materials than for opaque colorings," explains sales manager Lars Tonnecker. "Therefore, a compound is a better and cleaner solution than a masterbatch when it comes to product manufacturing. This is because defect patterns on the component, such as uneven color distribution, streaks and concentration differences, can be avoided or eliminated, since there is no need for additional metering of the masterbatch at the factory." "Whether headlights, taillights or displays - colored transparent plastics are mostly used in lighting applications. For this, there are precisely defined wavelength ranges from the manufacturers that must be adhered to and from which there must be no deviations," adds project manager Elke Milus. "We can adjust our compounds so that each batch corresponds to the other with minimal tolerances, with the highest reproducibility and thus the best quality." GRAFE has also recently invested extensively in its laboratory equipment and now has, among other things, a high-resolution spectrophotometer for measuring transmission in different wavelength ranges (UV/VIS/NIR = ultraviolet/visible/near-infrared). Thanks to its higher optical resolution in an extended wavelength range from 350 to 1,050 nanometers, the instrument even measures in five-nanometer steps instead of the usual ten-nanometer steps and is thus much more precise.

Design and production – complete in-house production The sonotrodes guide the ultrasonic vibration into the workpiece. We manufacture the sonotrodes individually tailored to the respective application and customer requirements and proceed with the development based on many years of experience and supported by the finite element method (FEM). The design of the sonotrodes depends on the ultrasonic application (welding, cut & seal, riveting, embossing, punching, cutting) and the properties of the workpiece to be processed.

Reinforcement or transformation pieces with the highest precision The SONOTRONIC component program includes boosters (amplitude transformation pieces) for ultrasonic frequencies of 20 kHz, 30 kHz and 35 kHz in various ratios. The booster is part of the ultrasonic oscillating unit, which consists of the components converter, booster and sonotrode. In the oscillating unit, the booster is interposed between the converter and the sonotrode.

Different frequencies for optimal welding results SONOTRONIC offers converters with three different frequencies: 20, 30 and 35 kilohertz, with outputs from 1,200 to 4,000 watts. There is a wide range of different variants for different applications, and waterproof types are also available. Depending on the application, the ultrasonic converters are equipped with four or six disk ceramics. The latter are mainly used in the packaging industry and for continuous ultrasonic applications. Via the disk ceramics, the vibrations are optimally transmitted to the ultrasonic tool (sonotrode), so that short process times and high process reliability are achieved. The high-quality housings are very robust and durable and have different HF interfaces.

For the fixation of the ultrasonic oscillating units The feed units are mainly used in special machine construction in industries such as the automotive industry or other plastics processing industries, the textile industry as well as in packaging machine construction and the food industry. For the various applications, they can be easily integrated into existing or new machine concepts.

Fast and precise control of ultrasonic processes What does the generator do? The ultrasonic frequency is generated in a generator. The generator converts energy from the electrical network into a high-frequency sinusoidal oscillation of 35 kHz or 20 kHz and transmits this to the oscillating structure, which consists of the converter, the booster and the sonotrode. Optimized control processes generate optimum ultrasonic oscillations.

Individual production of all parts nests in our internal special department The parts nest is the form-bound counter bearing to the sonotrode or the welding tools. In the finest precision work, we geometrically adapt the nests to the workpiece to be machined and the required vibration behavior. Based on original parts or on the basis of customer-specific CAD data, the nests are individually designed 100 % in-house and then manufactured,
