Fricke und Mallah supplies microwave technology of the highest quality to numerous branches of industry. The expertise of our experienced high frequency engineers enables us to understand the most demanding applications and deliver solutions that convince our customers.
Our expertise in building complex microwave systems has enabled many projects in the chemical industry.
Homogeneous heating without the formation of cold and superheated spots and optimized energy input are just some of the advantages of microwave technology. The reactions in the microwave field are much faster than in classic heated systems. Many syntheses have thus been improved or made possible. Therefore, microwave technology has established itself in this industry.
Due to the use of modern semiconductor-based generators, our systems are optimal for automated, sequential operation and are easy to handle.
The wide range of applications for microwave equipment includes in particular the rubber and plastics industries, where bipolar blends provide excellent heating of the product.
Production of rubber profiles
During the continuous vulcanization of rubber (elastomers) during the production of rubber profiles, the product is extruded directly into the vulcanization line. This is done by hot air channels, salt baths or microwaves.
Ultra-high-frequency (UHF) vulcanization systems achieve heating of the material as quickly as possible. The elastomer absorbs the microwaves, converts them into heat and vulcanizes them. This process is faster and achieves better results because the rubber profile vulcanizes more directly and homogeneously.
Recycling of plastics
Microwave technology improves energy and resource efficiency in recycling processes for polyamides and polyurethanes - both in the use of industrial and post-consumer waste.
Chemical recycling, supported by microwaves and intelligent magnetic catalysts, is a way to recover plastic monomers and valuable fillers (carbon or glass fibers). This contributes to compliance with recycling quotas and saves costs and resources.
