...kpit has always been a real challenge. ‧Continental now uses a combination of film insert molding, in-mold decoration and injection-compression molding to produce large, three-dimensionally formed plastic panels. The display increasingly sets the tone of a vehicle cockpit. Most current car models already have two full-color, graphic-‧capable displays. The instrument cluster usually consists of a large display (full digital cluster, FDC). In addition, there is usually a second display in the cen...

Inadequately dispersed pigments can result in disruption to the production process. Difficulties include variations in colour tone and strength, rapid clogging of filters and spinnerets, breaking of fibres during spinning, film tear, and a lack of strength in welds, coatings or print. Pigment concentrates or master batches have gained acceptance in recent years as pigments ...

Immediately after irradiation, the DSC curves indicate a shift of the crystallite melting points to lower values, si...

Special. Targeted Modification of Properties. Phyllosilicates. Unusually high thermal stability of compounds results from a combination of (polyamide+polypropylene) blends with organically modified phyllosilicates (organoclays) obtained via the extrusion process. The observed effects can be traced to a nanoparticulate distribution of the phyllosilicates and their orientation at the phase boundary between the polyamide and polypropylene. Stefan Reinemann et.al. Reports on the development of poly...

This room was split and partly covered with film, which had to be cut out at this point as a secondary operation. The problem was solved with a neat idea. The mould pre-punches the film with a cutting edge. “We can now simply lift out the film cut-out without any tools,” says Jenni and stresses that all the modifications w...

Alleged benefits include the lightning-fast curing of the ink layer, the improved adhesion versus water-based inks and a constant colour tone that does not require viscosity control. In return for these benefits, however, a higher price and more difficult adjustments during printing must be taken into account. Printing of smaller quantities of textiles, film or paper by means of digit...

... The outer layer of these blankets is therefore usually made of rubber. This material plays a very important role in these products. Only absolutely homogeneous surfaces ensure high dot and contour definition and excellent full-tone smoothness. The sensitive offset printing process requires the manufacture of blanket rolls to a precision of ±0.02mm over several hundred square meters of surface per batch. During use, care must be taken to ensure the inks and chemicals used to clean the blankets d...

The new BYK-mac measurement system objectively determines both parameters, i.e. changes in the color tone as well as the glitter effect (Fig. 3).

... This meant that the choice of component color was very limited and light or transparent colors could not be produced. Help is now at hand in the form of additives that have very low self coloration and thus practically no influence on the color tone. Up until now such additives were only available for the wavelength ranges around 800 and 1,050 nm. Laser absorbers have however recently become available that absorb in all the important wavelengths. Regardless of whether this is diode lasers at 80...
