Aluminum foil blister packaging machine blister forming

The poor forming of aluminum foil bubble cover of blister packaging machine is generally divided into three types: insufficient or inconsistent depth of forming bubble cover, bubble eye rupture after forming, and above wrinkling after forming.

1. Reasons for insufficient or inconsistent depth of forming bubble cover: the forming depth is not adjusted properly.

Solution: loosen the adjusting nut and adjust downward. Use vernier caliper to measure the depth of the forming bubble cover, which is 0.3-0.5mm deeper than the drug thickness. If the depth is inconsistent, use vernier caliper inner claw to measure the distance between the upper die bottom plate and the forming lower die in the forming station.

2. Reasons for bubble hole rupture after forming: the forming depth is too deep, and the elongation of aluminum foil is insufficient.

Solution: reduce the forming depth, aluminum foil for another purchase.

3. Upper wrinkle after forming: The forming depth is too deep, and the pressure between the upper and lower dies is insufficient.

Solution: reduce the forming depth, adjust the forming station nut, increase the pressure between the upper and lower dies.
