Vapormatt have been active in the development of wet blasting systems for use in extrusion die shops for several decades. Our experience has led to us developing a deep understanding of the finishes required by extruders in order to improve their die success rate and reduce the time spent on manual inspection and polishing.
The Vapormatt wet blast process involves a custom blend of abrasive media, compressed air and water that quickly and easily penetrates the critical bearing surfaces. With our science of control, the abrasive slurry flows through the dies, removing any caustic trace and aluminium that can be damaging to the profiles.
Our wet blast process is intensive enough to effectively polish the critical bearing faces, however with the introduction of water the abrasive action becomes less aggressive than alternative processes and this prevents any geometric changes to your die profiles. The benefits of the Vapormatt wet blast process in die shops are most clearly seen in the increased efficiency and reduced downtime during the inspection stages.
However, the Vapormatt wet blast process has more to offer extruders. With the level of cleanliness and polish achievable extruders are able to increase their die success rates and with increased nitriding success longer runs are possible.
There are a large range of manual, semi and fully automatic Vapormatt wet blast systems available that will cater for plants with 1 or 2 presses all the way up to those running many more. With Vapormatt, die shop managers are able drastically improve their die success rates and margins.
