Reduce production downtime by 75%

As a result of Cold Jet dry ice blasting, Preform mould manufacturers have been able to reduce their production downtime by 75% or more. Cold Jet dry ice blast systems are able to clean mould surfaces while the mould is still at curing temperature in the press.

The importance of clean mould cavities is a major concern in maintaining today's high quality standards. The build-up of unwanted surface residues from either the product mix itself, mould releases or the labeling process can create various problems, ranging from product release ("knock out") to inferior product quality and possible damage to tools from over-packing and straining. In addition to maintaining the cleanliness of the moulds, the Cold Jet dry ice blasting process also reduces and in many cases eliminates the need to disassemble the moulds as is required for traditional cleaning.


Cold Jet dry ice blasting removes the waxy, paraffin build-up that can lead to blemishes (orange peel effect) on the bottles while the moulds are hot and on-line.


The manufacturing of a polyurethane foam product used in sound dampening for autos and vans leaves the manufacturer with moulds coated with an isocyanate/wax mould release. Mould release build-up eventually causes "knock out" problems, and, in extreme cases, the wax release agent becomes encased in the polyurethane foam product, making the product unusable. With Cold Jet dry ice blasting, moulds are cleaned in only 15 to 20 minutes and the cavities are more thoroughly cleaned. Production up-time is increased significantly (can be more than 100 hours) and maintenance crews are now free to attend to other duties.


Cold Jet dry ice blasting can clean entire blow and injection mould cavities completely and effectively. Many leading blow moulding bottle manufacturers have discovered that dry ice blasting systems cut their daily mould cleaning time by about 80% simply by cleaning moulds hot and in place. Today, even the back 1/3 of the blow-mould surface and the entire deep-cavity injection moulds used to make test-tube shaped slugs are cleaned by dry ice blasting whereas it used to have to be cleaned by hand.

Cold Jet dry ice blasting has been shown to cut mould-cleaning time by 75% in the Rubber Industry, therefore increasing production time. Cold Jet dry ice blasting systems eliminate the need to remove and reinstall moulds during cleaning - decreasing downtime.


The buildup of fouling residue and mould release agents cause blemishes and unwanted flash to the final part. It also makes it more difficult to hold tolerances on parts, which can lead to increased scrap. Dirty moulds affect not only quality but productivity as well. Rubber parts will stick to the mould during removal, which increases cycle time, and in some cases, mould build-up can lead to over-packing, which in turn can cause internal strains to the tool.


Removing and reinstalling moulds may lead to tool wear, as well as risk damage to the tool during out-of-press handling. The use of Cold Jet dry ice blasting eliminates many sources of mould and tool damage.


Tire manufacturers have seen many benefits in using Cold Jet's dry ice blasting technology, including: reduced production costs of approximately $1 million per facility annually, press downtime reduced by 300% due to in-press cleaning, annual production increase, elimination of the need to hand drill micro vents, near zero-defect levels achieved, reduction in tool damage, and a reduction in the need to re-stamp sidewall lettering.
