The difference between injection compression moulding (B29C 45/561) and B29C 45/572 is typically that in injection compression moulding a movable mould half is used for shaping the material in the cavity, while in B29C 45/572 the already shaped material is pressed for compensating the volume change caused by the shrinkage. Pressurizing is typically done locally e.g. by pressurizing pins
It is further noted, that B29C 45/56 comprises a reference out, that B29C 45/572 takes precedence.

Illustrative example of subject matter classified in this group:
As seen in Figure 1, Element 30 is a cushion which can be inflated such that it projects slightly past the rear face of the mould-half, at least on three sides. Thus, by inflating the cushion 30 with a fluid at a pressure substantially equal to or greater than that of the blow-moulding fluid, the resulting action of these two fluids on the mould-half is an action that pushes toward the other mould-half 14.
In the extrusion-blow-moulding process, pressures on the order of 10 bars are generally used. Also, when the mould has a large cavity or several cavities, the forces exerted by the fluid pressures can be quite large. However, the use of a flexible cushion makes it possible to ensure that the compensating pressure is distributed uniformly over the entire rear face of the mould-half. In this way, the force of the first mould-half 12 applied against the second 14 is uniformly distributed over the entire joint plane of the mould, without the need to use particularly rigid mould-halves or mould clamping units, which allows costs to be decreased.

Illustrative example of subject matter classified in this group:
To close the blow-mould and to hold it closed with a high force for a blow-moulding process, the electric motor is activated to drive the push mechanism. The push mechanism, preferably designed as a spindle drive, moves the push rod out of the push mechanism and the electric motor reaches the required torque. Directly after the blow-mould has been closed with high force by an elastic deformation, the braking device is activated to hold the push rod in a state of constantly maintained tension in its instantaneous position and to hold the blowing mould closed with a required closing force.

After the seal 30 has contacted the upper lip of the parison 24 and the piston 38 moved upward against the biasing force of spring 80, a gaseous blowing medium, typically air, is quickly injected through outlet 14 and into axial passageway 46. The downwardly angled ports 51 extending from the axial passageway 46 through the inner wall 53 of chamber 34 causes a quick increase in pressure within the chamber 34. This increase in pressure within chamber 34 exerts a force on the annular pressure surface 72 of piston 38 causing it to press downwardly to ensure a complete and full seal by the sealing means 30 on the upper lip of opening 22.

Illustrative example of subject matter classified in this group:
FIG. 6 illustrates in a diagram the relation of a chronological blow pressure pattern 42, a stretching force development 43 as well as a stretching rod positioning 44. The scale of the time axis takes place in this case in milliseconds and the amplitude values are scaled in bar, Newton or millimeter. FIG. 6 illustrates that with respect to the positioning of the stretching rod 11, this stretching rod is initially moved essentially without development of a stretching force into the preform 1. After a contact of the stretching rod 11 at the bottom of the preform 1, the latter is stretched and a relatively great development of the stretching force takes place. After the longitudinal stretching is concluded, the remaining stretching force results from the stabilization of the preform in the stretched position while taking into consideration elastic restoring forces within the material of the preform. The blowing pressure sequence 42 shows the division into a pre-blowing phase during the carrying out of the stretching process and a principal blowing phase after a significant conclusion of the stretching procedure.

Control of a material-shaping process including controlling blowing pressure in terms of how fast/slow the pressure decreases. This may depend on preform stretch or position.
Illustrative example of subject matter classified in this group:
While blowing, the compressed air itself is preferably cooled to an adjustable temperature as well, which may be either higher or lower than zero degrees Celsius. Thus, the decrease of pressure can be faster, since the blown object has to cool less long, and the de-aeration time D thus decreases, and the production speed and the output of the blowing process increase. The decrease of pressure in area C can be obtained by successively going through more than one adjustable discrete pressure value or, when using an unlimited number of such adjustable pressure values, by running through a continuously adjustable curve, whereby the last set pressure value can amount to zero bar relative pressure in relation to the atmospheric pressure.
This place covers:
Control of a material-shaping process including controlling temperature of a preform.
Illustrative example of subject matter classified in this group:
Figure 1 depicts the outlet of the heating station 8, the heated preforms 22 are at a temperature comprised between the glass transition temperature of the material of the preform and its crystallization temperature, in order to obtain, at the outlet of the heating station 8, soft heated preforms 22 able to be deformed under the influence of a pressure injected inside the heated preforms 22, i.e. malleable preforms. The temperature is such that the preforms however still maintain their shape at the atmospheric pressure, meaning that they do not tend to be deformed without any pressure applied on them. As an example, for a preform made of PET in the dimensions range mentioned previously, the preform is heated at a temperature comprised between 100° C. and 140° C. It should however be noted that the more the preform has to be subjected to a greater expansion along an axial direction and/or along radial directions, the more the preform is heated at a temperature over the glass transition temperature, but without reaching the crystallization temperature, for example around 135° C. for a preform made of PET in the dimensions range mentioned previously. Consequently, for preforms having a high bi-orientation rate, defining the cumulated axial elongation and radial expansion to which the preform has to be subjected, one wants to work at the highest possible temperatures, but without crystalizing the material of the preform, in order to allow the preform to be deformed easily enough to reach the wanted shape of the container without the appearance of an overstretching of the material, possible with a temperature not high enough and/or of an high stretching rate.
The acquired images or film are then transferred to the control unit 50 and compared to the reference gauge. Furthermore, a sensor for sensing the temperature of the heated preform 22 could be provided and a formula for correcting the acceptable retraction depending on the temperature of the heated preform 22 could be applied. If one of the acquired images or one of the images of the film shows a profile of the preform radially diverging more than the reference gauge, then it is determined that the analyzed preform is unsatisfactory.

To give a concrete idea of this, the preforms are typically heated to a temperature of the order of 100° C. whereas the average temperature of the drawing rod remains of the order of 85° C.
