Even when the filling rate is high, the surface temperature of molded bottles is kept at a certain temperature or higher, and the bottles can be adequately sterilized with a sterilizer.

A preform is heated, the heated preform is sealed in a neck portion mold, a trunk portion mold and a bottom portion mold at a predetermined temperature range, and the preform sealed in the molds is blow-molded into a bottle. Any bottle is removed which has been molded in the neck portion mold, the trunk portion mold and the bottom portion mold the temperature of any of which is outside the predetermined temperature range, and a sterilizer is blasted to any bottle for sterilization which has been molded in the neck portion mold, the trunk portion mold and the bottom portion mold the temperature of all of which is in the predetermined temperature range.

Even when the filling speed increases, the surface temperature of a molded bottle falls within a constant range, and a sterilizer adequately sterilizes the bottle.

A preform is heated, the heated preform is sealed in a mold, the preform sealed in the mold is blow-molded into a bottle, the surface temperatures of a neck portion, a body portion, and a bottom portion of the molded bottle are measured, and the mold temperatures of a neck portion, a body portion, and a bottom portion of the mold is so adjusted that the measured surface temperature of the bottle falls within a specified temperature range.

Systems and methods control the operation of a blow molder. An indication of a crystallinity of at least one container produced by the blow molder may be received along with a material distribution of the at least one container. A model may be executed, where the model relates a plurality of blow molder input parameters to the indication of crystallinity and the material distribution and where a result of the model comprises changes to at least one of the plurality of blow molder input parameters to move the material distribution towards a baseline material distribution and the crystallinity towards a baseline crystallinity. The changes to the at least one of the plurality of blow molder input parameters may be implemented.

A machine for blowing or stretch-blowing bottles or containers made of a polymer material includes molds movable on a transport system. Each mold includes a front, back, and bottom with a first and second half-molds hinged about a hinge axis and a base. Each of the molds includes a mechanism for synchronized actuation of the half-molds and the base independently from the machine's motor, to cyclically form with shaped portions, a closed cavity for receiving a preheated preform and to allow expansion by blowing or stretch-blowing the preform inside the cavity to obtain a bottle or container. The base is wedge-shaped with a horizontal closing surface facing the bottom of the mold, and an inclined surface. The actuation mechanism includes a wedge-shaped element having a surface inclining towards the front of the mold. The inclined surfaces of the base and of the wedge-shaped element are) being slidingly coupled.

A device for blow molding a container from a preform. The device includes a mold base and a pedestal for supporting the mold base. An electric heating element is beneath the mold base for heating the mold base. An insulator is between the heating element and the pedestal.

A method for operating a device to produce a product includes capturing at least one quality data record that includes measured values of one or more quality parameters that each correspond to one property of the product. The method captures at least one associated machine data record including actual values of several adjustable machine parameters of the device, chronologically assigns the quality data record to the machine data record, and generates a first data record comprising chronologically-correlated measured values and actual values. The preceding steps are repeated at least once to generate at least one second data record. A correlation is determined between the quality parameter(s) and the machine parameter(s). The method provides a corresponding target value for at least one of the adjustable machine parameters on the basis of the control model, proceeding from a target value of the quality parameter(s).
