Thread: Just injected my first molds have a few questions please !!!!

You guessed it on the injector i made. I made it out of a liftgate shock. The one i used had leaked the oil out of it. I sawed it to the length i wanted. Beveled the end of the tube. Replaced the oring on the aluminum piston. 3/4"inside bore that is super smooth. I made the tip from an old broken torque socket. It fit perfect and tight in the bore. the socket had a hole in it's side i tapped a hole in the tube and put a set screw in it to hold the tip. Only problem i have had is keeping the tip hot enought so the plastic won't cool to fast I solved that problem by pulling the plunger back and let the tip set on the hot plate when i am taking the plastic out of the mold. I have also ordered some 3/4" aluminum rod to make some tips out of I think this will help the cooling problem as it should heat up faster. I have $0.00 in this injector. The shock was free ,the socket was broken, the partsman gave me the new oring, if i add the new tip i am going to make i will have 10.00 in about 24 tips. this is my hobbie so won't count labor. P.S It can be completely taken apart and cleaned the end screws off the rod and the piston and rod will slide all the way out. Cub4

I do no injecting but I have seen pans that might do what you want. My wife has a few Revere Ware pans that are very small, only about 4" across, and have a copper coating on the outside to even out the heat distribution. All stainless inside would give the silver bottom stated in another post. Those baits look good.
