SnakeHead Posted June 17, 2010 Report Share Posted June 17, 2010 How consistent are the results with these two color injectors? I have my eye on a multiple cavity mold, which fills all cavities with a runner, and I was wondering how well the two color injectors work on that type of mold? One last question, Do you get a lot of scrap (useless colors) from the sprue and vents? Thanks, Quote Link to comment Share on other sites More sharing options...

I have my eye on a multiple cavity mold, which fills all cavities with a runner, and I was wondering how well the two color injectors work on that type of mold? One last question, Do you get a lot of scrap (useless colors) from the sprue and vents? Thanks, I can tell you about the Basstackle one. It is real consistant in the result category. The design tends to keep the equal pressure on both colors and filling is a breeze. You can fill both colors at the same time from two cups of hot plastic. The only trick is to keep the temp of both colors within 10 deg of each other. I use it almost everytime I shoot and when I buy a new mold I always think of how it will work with the twinjector. I have used it in miltiple and the sprue is not useless, I set them aside and when I get a chance I get them and cut them in half as good as I can and remelt with the others and add them back to the main cup. The only time this does not work is with light colors. You would be real surprised how much you really dont throw away. I shoot four cups at a sitting, two of each color and end up with less than three oz of plastic I do not use. And it is not junk I just cant get it in the twinjector again. Another trick is to fill the twinjector all the way up and then inject. I just bought his new hog with wings mold four cavitys and it shoots like a dream. If you look real close the tails are two colors. Pretty thin to be that consistant. I just got a bears lizard mold with split tails and one tail is one color and the other is the other color, now these are right next to each other.I know you are asking about miltiple cavity molds but it works on the single cavity 90 deg fill sprues also but in my opinion the results are better in the nose pour molds. Hope this answers your questions. Frank Quote Link to comment Share on other sites More sharing options...

Frank Posted June 18, 2010 Report Share Posted June 18, 2010 I would love to see some pictures of all of that Frank if you don't mind some of your competitors seeing your work. I bet a couple presto pots sitting side by side would really help with that. too. I was wondering about two color injection in multi cavity molds myself. Look through the archives for a post called injecting video by me and you can see the twinjector in use. This was a while ago but it will give you the idea of what is going on. I have come a long way since then and have a few changes. As have alot of others. I was injecting a hand pour mold with two sprues. The new mold I have has four cavitys one sprue. I will post some pics this weekend of that mold in use. I am still using pyrex but now I put them on a griddle to keep them hot. I only micro the first time then I use a second contianer to remelt the sprues and slugs from the injector. If my son comes over I may do another video with the newest set up. Since my camera went into the canal trying to film a bait in the water.Frank Quote Link to comment Share on other sites More sharing options...
