Part of the formula is "blowing pressure." Increasing blowing pressure helps us play louder, but what happens to the intonation?
The air can then be switched to higher final blowing pressure such as 100 psi for final forming of the part.
The blowing pressure was maintained at 2.9 MPa for the three different blowing temperatures.
Find the blowing clamp force (to keep molds closed during air blow): Projected area of blown section x blowing pressure (around 100 psi) / 2000.
The blowing pressure is recorded versus time using a pressure sensor (the pressure value is actually different from the imposed blowing pressure).
A special mechanical mold locking system reportedly withstands 35 bar (507 psi) blowing pressure and leaves a smooth parting line.
The parison inflation stage is highly complex, involving the interaction of several process variables, such as the parison thickness distribution (parison programming), blowing pressure, parison temperature profile, and the material characteristics.
It focuses on reducing the volume of dead space, reducing the blowing pressure, and recycling the blowing air.
High blowing pressure forces the bottle against the hot mold.
blowing pressure. Priest says this approach is much less expensive than incorporating a high-pressure air compressor.
Besides minimizing material consumption, the new bottle reportedly saves energy in production through a reduction in blowing pressure and heating power, with no compromise of package performance.
With around 60 employees, they were a first mover in the low blowing pressure technologies.
