It has now become possible to apply the technique successfully to the precision-cutting and manufacture of refrigerator-door linings.the automatic pressure forming machines of the KMd range are your guarantee of maximum precision and optimum processing speed. outstanding quality and output rates can also be achieved in the production of refrigerator interior components.combined vacuum/pressure forming with connected steel-strip punching, mould-release movement in the tool and plug assist can all be carried out without problem.KIEFEL BFS SySTEMMAxIMuM PRECISIONwith cost-efficient technologypressure bellcutting bladeproductlower clamping frameforming toolplug assistFunctioning Principlen Mechanical and electrical design, plus high in-house manufacturing capacityn Machines and tools are put into service by process technicians with ample experience in the implementing of turnkey projectsn tools produced in-house by our own team of toolmakersn specialists in after-sales service and the supply of spare partsKIEFEL KNOw HOwI n l I n e t h e r M o f o r M I n g M a c h I n e s K I V / K I d s e r I e sKIEFEL – with the power it takesKIefel is a world leader when it comes to the design and manufacture of machines used to process plastic film materials. the company offers core expertise in the fields of forming and joining technologies. as a supplier to reputable manufacturers in various sectors, KIefel gmbh services customers in the automotive, medical technology, refrigerator and packaging industries.the headquarters of KIefel gmbh is in freilassing/germany. the company also runs its own network of sales and service centres in the united states, france, the netherlands, russia, china, Brazil and Indonesia, and is represented by sales partners in more than 60 countries worldwide.Kiefel gmbh is a member of the german Brückner group, a worldwide leading supplier of plastics machinery.KIefel is certified to dIn en Iso 9001:2000 standards.Company AddressKIefel gmbh Industriestraße 17–19 83395 freIlassIng, gerManYpo Box 3125 83397 freIlassIng, gerManYtel.: +49 / 8654 / 78-0 fax: +49 / 8654 / 78-490 e-mail: kiefel@kiefel.de www.kiefel.deThe data supplied by Kiefel in this brochure are technically oriented.
