Standard features: Up to 4000 psi injection pressure.
The catheter tip reforms and maintains shape, even under injection pressure, resulting in reduced whipping effect while contrast is injected and reduced risk of vessel wall injury.
Using pretreatment information, the initial design specified 50 bpm and 150,000 pounds of proppant with an injection pressure of 7,000 pounds per square inch (psi).
Tooling and o-rings often leak only when under clamp or injection pressure, conditions that cannot be replicated on the bench.
However, today's molding machines with the latest process controls provide the accuracy to hold mold temperature, injection pressure, and other variables within a tight enough window to allow most processors to mold precision gears.
The size of the FIFO injection unit determines the total shot volume and injection pressure.
The spring forces it closed with an air-tight seal as soon as injection pressure ceases.
The injection unit is a Super FIFO (first in, first out) type that is said to allow very fast compound changing, a fixed feeding point, high plasticization rate, high injection pressure, excellent temperature control, complete pull back of the screw and easy screw changing, according to the literature.
Standard features: Single or twin extruders, single/twin accumulators, multi-nozzle manifolds, injection pressure to 6000 psi.
Features include a maximum injection pressure of 43,530 psi and injection speeds up to 300 mm/sec.
The rubber injection molding unit features a screw with special intake toothing and compression zone, a plasticizing cylinder with intake pocket and effective temperature regulation, high injection pressure which continues into the mold without mentionable pressure loss due to the nozzle design, back pressure control and controlled temperature in the intake zone, according to the literature.
