Weißer+Grießhaber is one of the leading manufacturers of technical plastic lenses and optical components. Our products direct light precisely and reliably in safety-related applications such as automatic door systems, robotics solutions and industrial trucks. The highest standards of transparency, profile accuracy and surface quality are a matter of course for us and characterise every step of the manufacturing process.

Lifocork biocomposite materials combine the sustainability, low weight and feel of natural cork with the processability of plastics. Lifocork is suitable for a wide range of applications, with new ideas being introduced every day. Its comfortable feel and non-slip texture make it a good choice for handles and grips, where it has been used in sports equipment, tools and household items. Lifocork has also been used to manufacture bowls, trays, boxes and plant pots and toys. In 2K applications, the material can be overmoulded or co-extruded onto TPE, PP or PE. This allows for sophisticated designs and enhances consumer appeal with the integration of a soft-touch area. Plates, belts, endless tapes and tech profiles can be manufactured from Lifocork via extrusion. You also get a damping effect for orthopaedic shoe lifts by foaming Lifocork. We offer coloured Lifocork compounds or it can be easily coloured using a standard PE masterbatch, opening up even more design possibilities.

Lifolit is a family of high-quality, soft polyvinyl chloride (PVC) compounds, custom formulated to your requirements. We’ve been developing PVC compounds since 1965 and continue to engineer new solutions to address current and emerging market demands. To address consumer concerns over the potential health and environmental risks of certain plasticizers used in the manufacture of PVC compounds, we have developed the Lifolit range to include several non phthalate alternatives. This helps our customers to comply with tightening regulations governing the use of phthalates. Particularly in the toy and childcare market, where non phthalate compounds have become the industry standard in response to directives such as EU 2005/84/EC. We work with a number of raw materials and plasticizers to give the best performance / cost ratio while always keeping in compliance with the different levels of phthalate use. This includes DEHP free PVC as well as grades that are considered low in Volatile Organic Compounds (VOCs).

The LMF Easy XL is the large-format entry-level system of the LMF Easy series and has been specifically designed for users requiring a cost-effective laser marking solution for small batch sizes and large components. Based on the proven LMF Easy platform, the system stands out for its ease of operation and robust, compact machine design. The integrated fiber laser technology is maintenance-free and wear-free, offering an average service life of up to 100,000 operating hours. This makes the LMF Easy XL an ideal solution for workshops, small-scale production, and as an entry point into industrial laser marking. The system is suitable for laser marking of all types of metals, coatings, and high-contrast plastic markings. Typical applications include Data Matrix codes, serial numbers, nameplates, as well as complex graphics and artworks. A key feature of the LMF Easy XL is its large working area, allowing the processing of components with heights of up to 500 mm and dimensions of up to 650 mm x 450 mm in width and depth. This makes the system particularly suitable for bulky or large-volume components where simple handling is essential. The LMF Easy XL combines intuitive operation, reliable fiber laser technology, and a large processing volume, providing a flexible and economical entry into laser marking technology.
