For uninterrupted work in production processes, where products are vacuum packets, such as pills or various dragees, with the aid of sealing press packaging, the press plates, which perform this pressing, must be perfectly clean.
Usually, the plates are cleaned either due to inappropriate vacuum or due to the poor pressing of the packaging parts and consequentially poor sticking of the forming and cover foil of the press packaging. Cleanliness of sealing plates may be ensured in several ways, but not all are efficient, or, due to the mechanical nature of the cleaning, cause the destruction of the sealing plate, which is a very expensive element considering the duration of its use.
At FerroČrtalič we developed a special automatic machine for the cleaning of sealing plates with soda - SODABLAST 1 AUTO ECO.
This is a very efficient cleaning process without consequences for the basic material. Due to the small granulation, the grains of soda reach all corners and remove filth without causing any damage to the basic matrix even after several 100 cleaning cycles. A fully automatic procedure makes the cleaning very simple, requiring only the appropriate choice of programme regarding the dimensions of the plate. It is a major advantage that sealing plates may be cleaned hot and returned, still hot, into the production process, which enables an uninhibited process of packaging. Cleaning with soda may be used on all surfaces, where it is important for the basic material to remain undamaged, making the actual use literally unlimited.
