These tools are manufactured to avoid the problem of Granule contamination during the tabletting process that can cause costly manufacturing problems. ‘Black Spots’ on tablets resulting in high numbers of rejected tablets, increased wear of punch guides and tightening of upper punches can result in excessive machine down time and high maintenance costs. So to prevent from this huge loss and rejection of tablets sealed groove punches are manufactured. This type of Punches are used to prevent
The tools from black spot, wear, machine lubricant oil and dust. The groove seal improves the Punch performance and make it more durable by increasing its life period.
