I have to keep both of them in mind. Holding center to center on the lens insert to 2 microns so that is critical as well as the surface finish. We are looking into the drawings now to see what is feasible for cooling lines and if that does not work incorporating smaller holes in the tool to...
It is an Injection mold. I would have to look at the tool drawings and see if there is enough room to adapt cooling line to the inserts themselves. I could rig up a solenoid valve that after injection I trigger the valve to allow the water to enter the tool. I think I would have to be careful...
Ours is a class 7 used strictly for molding. ours only has water and air lines coming into the the room. Air to operate the robotics and water to cool to molding machines. We do not have the LN2 or nitrogen plumbed into it. The unit I demoed in house uses a portable tank for the CO2 cooling...
Tool running with Electric Heaters, job runs in a clean room so steam or air is not an option. In order to reduce the tool steel temperature down low enough I would need to look at CO2 cooling directed at the insert. I have had someone come in with the unit for a demo but tough to justify for...
I can not run the tool at a cooler temperature. When this is done the clarity of the part is gone and the light transmission going through the array diminishes enough to make the part NG. In order to keep the clarity there I need the 280'F steel temperature. I wish that I had induction heating...
Currently running a lens part using PEI resin. Experiencing plate out on the diamond turned insert causing lens quality to be bad. Looking for anyone who may know of a way to stop this from occuring or even a way to clean it off without damaging the insert. Material supplier no help, plate out...
Our material supplier has not been that much help. Due to the size of the plate out they can not get enough of a sample to do testing on. The only response that they sent me was that they feel its low level ligamits coming out of the resin. We have tried dedusting resin before molding, tried...
Molding a very small lens using PEI or Ultem for the base polymer. Problem is plate out of the Ultem resin on our diamond turned inserts. I know that there are release coatings that could be used and I am looking for anyone who may have this same issue or someone who already found a cure for...
