Problems solved by technology

High precision in the manufacture of components is complex and correspondingly expensive
[0007] In addition, even when the individual components or components are produced very precisely, different aging states of components or components of the same type can occur, and thus different wear states can lead to containers produced by different forming stations. The deviation between the increases over the duration of use

Embodiment Construction

[0058] exist figure 1 The structure of a device 10 known in principle from the prior art for producing containers from preforms made of thermoplastic material is shown in FIG. This view shows such a device 10 in the form of a rotary machine with a rotary working wheel 20 with at least two forming stations 16 . In the region of the forming station 16 , the preforms 12 are formed into containers 14 by biaxial expansion.

[0059] In a typical configuration, the typical apparatus 10 for making the container 14 includes a tempering apparatus 26 for thermally conditioning the preforms 12 . As shown here, the tempering device 26 can be arranged upstream of the working wheel 20 so that the preforms 12 can be heated before reaching the forming station 16 . The schematically shown preforms 12 , also referred to as preforms, can be continuously conveyed from the feed device 22 to the tempering device 26 by using the transfer wheels 24 . The preforms 12 are transported along the heatin...

Abstract

The invention relates to a method for producing containers ( 14 ) from preforms ( 12 ) made of thermoplastic material by means of a blow molding machine ( 10 ) having at least one tempering device ( 26 ) and a Forming device of at least two forming stations ( 16 ), wherein the temperature of the preforms ( 12 ) is controlled by means of the temperature control device ( 26 ) according to a predefinable first control parameter, wherein by means of the temperature control device ( 26 ) One of the forming stations ( 16 ) forms the temperature-controlled preforms ( 12 ) in each case into containers ( 14 ) according to a second predefinable control parameter, wherein for each forming station ( 16 ) an individual preform is preformed at least one second control parameter of the second control parameters. The invention also relates to a blow molding machine ( 10 ) designed for carrying out the method according to the invention for producing containers ( 14 ) from preforms ( 12 ) made of thermoplastic material.

Description

technical field [0001] The invention relates to a method for producing a container of thermoplastic material according to the preamble of claim 1 and to a blow moulding machine according to the preamble of claim 9 . Background technique [0002] It is known to manufacture containers from preforms made of thermoplastic material, eg preforms made of PET (polyethylene terephthalate), by means of blow moulding moulds, wherein the preforms are conveyed in a blow moulding machine to different processing stations (DE4340291 A1). Typically, a blow-molding machine has a tempering device for tempering or thermally tempering the preforms and a blow-molding device with at least one blow-molding station, also referred to as a molding station, in the region of the blow-molding station. The preforms, which have been individually tempered before, are expanded into containers. The expansion is effected by means of a compressed gas (usually compressed air) as forming fluid or pressure mediu...
