Blister is negative pressure molding equipment - Union star packaging machinery

Blister are negative pressure molding machine production, will be used in several devices. A, clamping equipment of plastic forming, sheet is fixed on the clamping assembly. In hot forming of universal and composite thermoforming machine to facilitate more fixed clamping assembly of various size sheet. Have a plenty of the whole machine with a set of clamping frame. The clamping assembly can be divided into two kinds: one kind is frame type, another kind is split type. Frame type clamping assembly consists of upper and lower two frameworks. Sheet between two frameworks. Framework under a framework for open, maintain fixed state. Simplex bit molding machine on the framework of each type of lower fixed on the molding room directly. Parison and products with the hand pull out the manual and semi-active molding machine, when the frame size is very big, there are in safe operation within the framework of open scale assembly. The larger parison forming glide, clamping force can within relatively wide scale adjustment, therefore, take two bags rubber roller, with the spring pressure to each other, and equipped with a pressure adjusting assembly. Continue's clamping piece molding machine is the zipper on both sides with the front and rear brake work together. Clamping assembly is best to take active control, in order to move the agile, can contribute to the progress parts quality and compliance. Second, vacuum heating thermoplastic plastic sheet and film forming process, the heating is one of the important process of sheet. The continuous time and quality of electrical heating depends on the structure of the heater, after the appearance of radiation temperature of heat transfer of thermal inertia, sheet and heater, the interval between radiant energy absorbing coefficient of website production price, heater appearance characteristics and thermal physical properties of materials. Commonly used radiator heater electric heater, crystal and infrared heater. Vacuum system consists of vacuum pumps, vacuum equipment and storage tanks, valves, piping, and vacuum gauge, etc, in vacuum forming to take separate type vacuum pump, the pump vacuum should reach 0. 7 ~ 0. 09 Mpa( 520毫米汞柱) The above. Storage tanks as usual was made of thin plate welding cylindrical box body, bottom is elliptical. The capacity of the storage tank should be at least half than maximum molding chamber capacity. You must have appropriate valves, vacuum tubes, to control the vacuum narrow capacity. The rotation of the vacuum pump power is determined by the size of the molding equipment and forming speed, larger or molding equipment commonly used to 2 - fast 4 kw. Vacuum system among large factory production and development of the specific requirements. Four, compressed air equipment pneumatic system by the machine itself with the compressor, storage tanks, workshop director path sets, valve, etc. Molding machine necessary pressure to zero. 4 - 0. 5 mpa compressed air, vacuum blister forming machine widely adopt the piston type air compressor. Also can use large supply of screw air compressor whole factory. In addition to a large number of compressed air shall be in shape, there are at the beginning of the part when used for stripping, finished product outside such as cooling and manipulation of the mold frame and operation sheet parts move.
