First dry systems for bottling lines thanks to new DuPont Delrin grade for conveyors

Du Pont Engineering Polymers : 01 August, 2001  (New Product)
At the Drinktec Interbau World Fair for Beverage Technology (Munich 20-27 September 2001) DuPont and leading conveyor chain and belt manufacturer Regina Sud of Italy will jointly announce the successful commercial introduction of Regina's DK family of conveying components. The DK family is based on a new grade of DuPont's best-selling Delrin acetal resin, modified with Kevlar., that is especially developed for high performance glass container and filling conveyor systems.
At the Drinktec Interbau World Fair for Beverage Technology (Munich 20-27 September 2001) DuPont and leading conveyor chain and belt manufacturer Regina Sud of Italy will jointly announce the successful commercial introduction of Regina's DK family of conveying components. The DK family is based on a new grade of DuPont's best-selling Delrin acetal resin, modified with Kevlar., that is especially developed for high performance glass container and filling conveyor systems.

The low coefficient of friction and low wear of the new grade - Delrin 100KM, means that high speed conveyor systems equipped with Regina DK chains and belts demonstrate even better wear and abrasion resistance than those made of previous grades of DuPont's acetal resin, which has been used for bottling plant conveyor mats for the past 20 years. This means that, for the first time, glass, can and PET lines can be run using 'dry' systems (using either substantially reduced lubrication or even no lubrication at all) for substantially longer, uninterrupted service periods than with metal chain conveyor systems, with fewer scheduled and unscheduled down times.

The result is significant improvement in production and cost for glass bottle manufacturers and bottling facilities, which save the capital investment associated with installing lubrication equipment and the consequent cost of running the equipment. Moving to a 'dry' environment also means less mess and a more environmentally acceptable working environment for plant employees.

Delrin is a tough, lightweight, durable, wear-resistant, low friction and low noise, high performance acetal resin solution for today's bottling industry. It offers enhanced quality and performance, uncompromised reliability and greater design freedom than metal or other plastic solutions. Regina DK chains and belts of Delrin therefore need less maintenance than chains and belts of other materials.

A further advantage of using Delrin 100KM for glass bottling lines is that conveyor belts of the same material can be used for all the beverage container production lines in the plant, including lines for aluminium cans and PET bottles. Until now, a single plant may have been fitted with conveyor systems of plastic (for cans and PET bottles) and metal (for glass bottles). Use of Delrin 100KM throughout the plant gives bottling plants the production flexibility required in today's competitive environment.

Prior to the commercial launch, conveyor systems based on Delrin 100KM have been test marketed in cooperation with Regina Sud S.p.A. of Cernusco Lombardone, near Milan (Italy) since early 1999, with great success. Regina reports that more than 50 percent of its customers now specify conveyor belts based on DuPont's new acetal resin grade, which are marketed under Regina's DK brand.

Paolo Deco of leading global glass manufacturer Bormioli Rocco S.p.A. of Parma (Italy), a Regina customer, said: 'Regina DK chains and belts perform very well in dry conditions, and display very low wear.'

Regina Marketing and R&D Executive, Maurizio Viglino, said: Regina Marketing and R&D Executive, Maurizio Viglino, said: 'Regina DK chains and belts based on Delrin 100KM are winners for customers like glass manufacturers and bottling plants, which can now operate in dry environments at reduced cost. Since the introduction of our DK brand products in 1999, the trend among our OEM and end user customers is to switch to our DK belts and chains of Delrin instead of metal or other plastics, because of the many benefits the material brings.'

Regina Application Engineer, Valerio Carati, said: 'Our customers have long been asking us for a way to bring bottling lines into a dry environment in order to cut the cost of lubricants, reduce maintenance and improve working conditions. When we found a solution to their needs, they were incredulous at first, but once the new conveyors equipped with DK belts of Delrin KM100 are installed, they are invariably pleased with the result.'

Regina is a worldwide market leader in the manufacture of chains and belts for a wide range of applications. Founded in 1919, the company has affiliated companies in Europe, America and Asia.
