The REACH regulation on chemicals is intended to ensure a high level of protection for human health and the environment. Since it came into force, many substances previously used to clean production equipment have been reclassified.

Replacements for Problem Solvents

Färber & Schmid GmbH offers a number of substitutes for the “stalwarts” among solvents. The second part of this series looks at replacing methylene chloride and acetone and removing isocyanate.

Producing transparent and spotless headlight lenses by injection molding is extremely demanding, because even the slightest impurity becomes visible in these parts. At K2013, M.P.I. Srl – Moulds Plus International, Villalvernia, Italy, presented two newly developed types of their Ultra Purge purging compound developed specially for PC and PMMA applications. These purging agents induce a chemical reaction to purge plastic, color or carbon residues from the screw, barrel and hot runner system. As a result, according to supplier information, they reduce idle times due to color or material change, and help eliminate the dreaded “black specks”.

Color exchanges are a troublesome problem in plastic processing, particularly if hot-runner molds are employed. The start-up scrap produced during color exchange and the machine downtime must be reduced to a minimum. The best solution is based on optimization of the production technology and does not require modifications to the machine, mold or material.

Clean molds at the push of a button: A procedure that frequently takes several hours is now claimed to be possible within seconds, thereby considerably extending the inevitable maintenance intervals. At least that is how Husky Injection Molding Systems in Bolton, Ontario/Canada introduced a self-cleaning technology for injection molds at the NPE 2015. The new cleaning function is part of a package solution for the HyPET HPP5 preform production system, enabling it to operate for half a million cycles without downtimes for cleaning and greasing.

Avoiding Shutdowns

Mold cleaning is a challenge with a very small, 0.8 g light injection-molded part. The use of an efficient dry ice cleaning system not only increases product quality, but also reduces cleaning time, increasing both equipment availability and production capacity.

Mold cleaning with dry ice microparticles saved 400 hours of cleaning time per year, which corresponds to an increase in production capacity of 500,000 parts

Due to today’s high quality industry standards, cleanliness is an important factor and thus, injection mold cleaning is one of the most important prerequisites to yield high product quality. Through the use of dry ice, the Hans Geiger Spritzgießtechnik GmbH was able to increase not only its quality but also its overall productivity.   

Clean Gently and Reliably with Dry Ice   

Mold Surfaces as a Quality Determinant 

Pelletron Corporation in Lancaster, Pennsylvania, USA, improved their DeDuster unit with fully automatic material feeding. The series was developed for product cleaning with large loading capacities in plastics production plants, but can well be used for any other type of granular product. Pelletron will showcase their new DeDuster series. The throughputs of the equipment range from 18 t/h up to 150 t/h. A new type of material feeding unit makes expensive and heavy rotary vane feeders unnecessary. The fully automatic equipment controls and distributes the material flow homogeneously throughout the air wash decks. Pneumatic drive cylinders with integrated setting element move the feed valve in the desired position.
