LATEX FOAM, TECHNOPOLYMERS AND COMPOSITES RF Systems designs and manufactures Radio Frequency machines for latex foam, construction materials and chemical industries, that speed up and improve the efficiency of drying and other thermal processes, cutting energy consumption and operating costs. Established in 1990, RF Systems manufactures Radio Frequency equipment for the drying, vulcanizing, thermosetting and curing of latex foam, technopolymers and composites. Driven by customers' challenges, RF Systems aims at enhancing industrial drying and thermal processes through state-of-the-art RF...

VULCANIZATION AND DRYING OF LATEX FOAM Radio Frequency vulcanizing and drying of mattresses, pillows, sheets and other latex foam products Vulcanization and drying processes in latex foam production factories have always been an expensive and challenging task: latex is a good thermal insulator and steam heating is a slow process with inherent problems of product degradation. At present the prevailing method of transferring thermal energy for the industrial vulcanization and drying of latex foam is heat transfer by thermal conduction and convection with steam and hot air serving as energy...

The Radio Frequency technology is based on electromagnetic fields that generate heat within the product mass and allow rapid vulcanization in a few minutes. Being an endogenous process, no metal pins or expensive metal moulds are required: in fact, the product can be vulcanized in light and cheap plastic moulds, allowing for a more flexible design and easier product stripping. The drying process can be carried out very quicky as well: the water evaporates in the surface as in the core at the same time (also in shaped items), leaving the product uniformly dried, without yellowing or wet...

DRYING AND THERMOSETTING OF PU FOAM Radio Frequency drying and thermosetting of polyurethane foam on various substrates Polyurethane foam is commonly used in many application fields and products such as thermal or acustic insulation, mattress pads, couch or chair filling. Being an insulating material, the drying and thermosetting process is often slow and inefficient, if performed with conventional technologies. Radiofrequencies, on the other hand, are selective towards the water and therefore can heat up and dry the substrate quickly. RF machines can perform the entire process or work in...

DRYING OF CERAMIC AND OTHER COMPOSITE MATERIALS Radio Frequency drying of sanitary ware, tiles, technical ceramics etc.. The problems related to the delicate process of drying ceramics after pressing or cast-moulding, especially if they have a complex form, are well-known. Cracks in particular occur very frequently and cause breakings - both before and after baking - with consequent product waste which can affect up to 30% of the total production. Instead, RF technology enables to dry highly porous ceramic substrates in a short time and in a very uniform way, thus eliminating the risk of...

LATEX FOAM, TECHNOPOLYMERS AND COMPOSITES DRYING AND THERMOSETTING OF IMPREGNATED RESINS Radio Frequency drying and thermosetting of infused resins in fiber mats, non-wovens etc... Impregnated resins are used in a large number of substrates including construction materials, aircraft and automotive industry, packaging, furnishing and textile industries. The RF treatment can be efficiently applied to a variety of resin and binding agents on several substrates such as fiber mats, paper, wood etc.. It ensures uniform moisture leveling and quick cross-linking/thermosetting. The equipment...

LATEX FOAM, TECHNOPOLYMERS AND COMPOSITES DRYING AND GLUING OF PAPERY SUBSTRATES Radio Frequency drying and gluing of cardboard, abrasive paper etc.. RF Systems has developed specific machines for the rapid curing of glue/ink/varnish and drying of papery substrates (cardboard, abrasive paper, etc..). The process is carried out in-line uniformly in just a few seconds or minutes and prevents deformations and scalding. The equipment configuration is extremely flexible and additional modules can be added to cope with higher capacities. No migration of chemicals or yellowing In-line non stop...
