The reprocessing of tubular glass (e.g. to produce ampules or syringes)
means that a high degree of cleanliness must be assured in the
manufacturing process. In addition to classical ampule pens
manufactured from our FH421 material, graphite pressure rolls and
shaping mandrels have recently been supplied by Schunk which reduce
the oil content (and sometimes make it unnecessary).
