Hamer-Pack - BPC25-M
The Hamer BPC25-M is a fully automated blister machine of modular design for forming, filling and sealing of medical devides and pharmaceutical products. Main specifications Suitable for clean room operation
 Main frame configuration
Individual station description Heating station Lower heater with infrared ceramic resistances and a regulation system of shutters built in stainless steeel which allows adjusting of the heating area according to the forming index. The lenght of the heater is three times the maximum index possible in this machine and there are several heating clusters, each one capable of its own temperature adjustment. An in-built control system ensures all heating elements are working as expected. Forming station Thermoforming action is done by vacuum assisted with air pressure (up to 6 bars). Forming cycle begins by clamping a preheated film and applying a moderate vacuum action to stretch the film. Then, while material is still within the proper temperature range, upper and lower platen move in and they seal the preheated film to the mould. A strong vacuum action combined with air pressure is applied to form the part. Once formed, vacuum action is reverted and air is blown to separate the formed blister from the mould. This forming process is usually used in combination with plug-assist forming. This technique distributes the material more evenly over the mould thus achieving deeper draws. Vacuum air flow and forming pressure are controlled by means of servo-valves, operated directly from the control panel of the machine. All relevant parameters (including mould temperature) are monitored and each forming cycle is individually validated. Air pressure used in the forming action is filtered to remove particles larger than 0.01 microns, therefore being this machine suitable for operation in Class 7 cleanroom. Lower platen is motioned by a vertical pneumatic cylinder in combination with a mechanical toggle system. Upper platen is motioned by a servo driven spindle. This system allows a high degree of accuracy in the forming process. Machine is provided with a built-in pin-hole detection of the formed parts by vacuum decay (leak detection) which may result from original defects in the forming material.  Sealing station Sealing of lidding material is done by applying pressure and temperature in the sealing press. Lower platen is motioned by a vertical pneumatic cylinder in combination with a mechanical toggle system. Upper platen is motioned by a membrane pneumatic cylinder. Sealing pressure is adjusted by means of a servo-valve operated from the control panel of the machine. Effective applied sealing pressure is monitored each cycle by means of a pressure switch. Temperature in the sealing tool is monitored one each cycle and it can be measured in a precise manner with calibrated thermocouples.  Steel rule die-cutting station Sealed blisters are trimmed from the web with a steel rule die mounted on a press. As cut progresses, the press consistently brings the die to the same line on the backing plate. Lower and upper platens in the cutting station are motioned by a pneumatic cylinder assisted with a mechanical toggle system which multiplies the pressing force. Cutting pressure is adjusted by adjusting the position of the upper plate. This adjustment is motor driven. Temperature in the cuttinh tool is monitored one ach cycle and it can be measured in a precise manner with calibrated thermocouples.  Discharge blister station Sealed blisters are discharged by a tooling provided of suction cups which holds each sealed blister from the top and moves them onto an external parallel conveyor belt. The system allows individual discrimination between god and bad parts. Twin scrap winding unit A double winding unit is used to collect forming and lidding scrap in separate rolls.
