What is the best possible cooling time
for this medical luer?
I can already hear the protests: "You want me to increase my fill time; increase my gate size, which will increase my pack time; and heat my cooling water, which will increase my cooling time
. You're killing my cycle!" If we were molding PP, you'd he right.
A pressure control knob allows the operator to hold pressure constant during cooling time
for better joint integrity, circle No.
The system is designed to accommodate flaskless molds at a maximum rate of 120 molds/hr with 70 mm of in-mold cooling time
. These molds are indexed on pallet cars that carry two molds each.
Components of the cycle included injection time, pack/hold time, cooling time
, and clamp-open time.
It was found that when the initial voltage level was decreased gradually and the total power supply reached 86% of the value of that equivalent to 75 V applied for 220 s, thermal degradation of the resin close to the wire was unlikely to occur and the cooling time
could be shortened.
Users plug in the profile shape and material, and the computer simulates the cooling time
needed by calculating the convection heat-transfer coefficient from the profile into the coolant, while taking into account how profile mechanical properties are impacted by specific cooling times
To achieve sand temperatures below the 212F, the cooling time
increases and this process is no longer instantaneous.
At two melt temperatures the blow time was varied and the tail temperature measured as a function of cooling time

is reduced by increasing the flow and speed of water in the mold and changing the temperature and humidity of the blowing air.
This defect can typically be fixed by lengthening the cooling time
or adding a water nozzle to the tooling in the area of concern.
