SOFT INTEGRAL PUR FOAM
Wide range of products called REHA program – armrests or headrests for wheelchairs and other rehabilitation aid tools, such as equipment casings and resting parts for gynecological chairs and infusion sets.
Here, it was necessary to meet the washability and resistance to disinfection detergents, as well as the neutral behavior of the material that comes to a contact with a human skin.
SEMI-RIGID INTEGRAL PUR FOAM
Armrests for office chairs, anti-vibration handles for manual electric tools, parts for cabins of construction machinery, handles of medical devices, transporting panels of airport luggage conveyors, etc.
A fundamental requirement for these products is a demand for mechanical resistance of parts while maintaining its pleasant touch. In some cases it was necessary to reduce the flammability of polyurethane foam with respect to the use of parts in the air rescue services.
RIGID INTEGRAL PUR FOAM
Covers and casings for medical instruments, equipment for dental chairs.
Technology of production of covers from hard integral polyurethane foam is suitable for small and medium production runs, when production equipment is amortized in relatively small number of products. Molds are much cheaper for this production if compared with injection molds for thermoplastics; on the other hand the products are more expensive due to the higher price of the base material and lower productivity. After applying paint, the parts are aesthetically on significantly higher level than parts molded or vacuum formed.
COLD PUR FOAM
Fittings for seating furniture, foaming of entire furniture components by applying cold PUR foam into the prefabricated coating of leather or leatherette. The technology was developed thanks to the grant program for business innovation subsidized by the Ministry of Industry and Trade of the Czech Republic. We had to solve these fundamental tasks: Preforming of a suitable type of leatherette so that when adhered to a supporting skeleton it can be filled by cold PUR foam in the mold. Furthermore we had to develop materials and technologies suitable for this kind of foaming and we had to design forms for such production.
The main advantage of the final product is the fact that it has no seams, which are problematic as far as the hygiene is concerned for dental or surgical gynecological seats.
THE COMBINATION OF RIGID AND SOFT INTEGRAL PUR FOAM
Cabins of vehicles – the dashboard, door handles. This specific product is designed for use as a part of a cabin of a crane. This project was subsidized by the Ministry of Industry and Trade of the Czech Republic.
We faced a task to develop parts with so-called “soft touch” surface while meeting demanding criteria for use in vehicles, which is mechanical strength and shape and color stability over a wide temperature range. Due to the low production the emphasis was to solve the task with low initial costs, while the price of the product was not that crucial. A key problem was to develop materials suitable for this purpose, then resolve the coherence between the supporting layer of hard polyurethane integral foam and soft integral foam that creates the „soft touch“ surface of the product and finally create the desired surface finish of the outer layers of products.
For PUR production – it is a combination of a functional cavity from hard durable resin and a bearing block of aluminum. The surface of the mold is of long durability, highly resistant to mechanical damage, for example when inserting inserts or metal braces.
Masking templates for manufacturers of car lights and toys. For their production we use technologies that ensure perfect reproduction of the shape of the surface being masked – electroforming, lamination of carbon composites or 3D printing.
