sticky Posted October 27, 2015 Report Share Posted October 27, 2015 I just can't figure out why my baits turn out like this. I've tried making sure the temps are even. I've shot it slow and fast. When I can get it to work right, it makes great baits, I just need a little help. What do you guys think I'm doing wrong? Quote Link to comment Share on other sites More sharing options...
sticky Posted October 27, 2015 Author Report Share Posted October 27, 2015 The picture didn't load. I'll try to add it when i get home. The colors are all swirled together and are very inconsistent Quote Link to comment Share on other sites More sharing options...
ruthunter Posted October 27, 2015 Report Share Posted October 27, 2015 If your mixing block isn't perfectly square the colors will twist. Quote Link to comment Share on other sites More sharing options...
sticky Posted October 28, 2015 Author Report Share Posted October 28, 2015 Maybe I'm turning it a bit. I'll keep note of that the next time I shoot some baits. Thanks you. It seemed like the last time the bottom color was covering the top color a bit Quote Link to comment Share on other sites More sharing options...
Apdriver Posted October 28, 2015 Report Share Posted October 28, 2015 The twin injector just mixes in the middle a little. You will rarely, if ever, get that lam plate seperation, that crisp horizontal line, with your twin injector. Nature of the beast. Quote Link to comment Share on other sites More sharing options...
Apdriver Posted October 28, 2015 Report Share Posted October 28, 2015 Also, let me say, some molds laminate better than others. Quote Link to comment Share on other sites More sharing options...
sticky Posted October 28, 2015 Author Report Share Posted October 28, 2015 I understand I'm not going to get the same effect as the plates. It just seems like the bottom color is overtaking the top color. This picture won't load because of the size. I'll take another tonight . I appreciate all of the input Quote Link to comment Share on other sites More sharing options...
ipt Posted October 28, 2015 Report Share Posted October 28, 2015 one color will usually take over the other if you are using a dark and light, or if one or both colors are translucent. the best way to get a good looking 2 color bait is to make sure they are opaque colors Quote Link to comment Share on other sites More sharing options...

ipt Posted October 28, 2015 Report Share Posted October 28, 2015 yeah it looks like you may have one hotter than the other, or maybe you arent getting even pressure from each. my advice would be to: Clean both injectors and o-rings. Make sure both your plastic is around the same temperature (use an IR thermo). Inject slow smoth and steady. 1 Quote Link to comment Share on other sites More sharing options...
sticky Posted October 28, 2015 Author Report Share Posted October 28, 2015 Alright thank you ipt . I was thinking it might be a heat issue. I'll give it a try tomorrow when I shoot some baits for this weekend. No bait making tonight. I can't miss the game Quote Link to comment Share on other sites More sharing options...
Frank Posted October 29, 2015 Report Share Posted October 29, 2015 Looking at the pictures both temps are to hot. If you want to shoot white as a belly both temps should be around 310 or lower. This way it won't have time to mix. Smooth steady pressure will get you what you are looking for. The thicker the plastic is the better the laminate will be. 1 Quote Link to comment Share on other sites More sharing options...
sticky Posted October 29, 2015 Author Report Share Posted October 29, 2015 Alright frank. Thank you. I'll shoot some baits later today or tomorrow. I'm definitely going to watch the temps a lot better Quote Link to comment Share on other sites More sharing options...
MonteSS Posted October 29, 2015 Report Share Posted October 29, 2015 Make sure blending block is warm/hot Same temp plastic each side Same amount plastic each side Same viscosity (thickness) plastic each side Burp injector (IMPORTANT) Block straight Smooth, not too fast, steady pressure, on each side Hold pressure 10 secs Quote Link to comment Share on other sites More sharing options...
Cub48 Posted October 30, 2015 Report Share Posted October 30, 2015 Franks right on the plastic too hot. I have just started shooting with twin injector and ran into the same problem. But i was looking at mine and the ones that i shot last were looking good then i reheated my plugs and they started mixing. Also my infra red themo is not accurate above say 250F i bought a digital candy thermo with the metal probe i checked both the infra red and digital and after 250f the infra red don't read right. the plastic is hotter than it reads.Cub48 Quote Link to comment Share on other sites More sharing options...
mark poulson Posted October 30, 2015 Report Share Posted October 30, 2015 I thought my digital ir thermometer was wrong, until I figured this out. I found that the plastic is cooler on the surface than in the middle, so I stir and check the temps of the middle stuff as it comes up.

I found that the plastic is cooler on the surface than in the middle, so I stir and check the temps of the middle stuff as it comes up. Finally someone who understands you have to be stirring the plastic to take the temp with an ir temp gun. Even a digital candy thermometer need some stirring to be right. I have both and they are pretty much the same when all things are equal. Heat up plastic long Enough and you will find that temps in plastic vary so much it is unreal at times. some times I want the temp so low I have to break though a skin of cooled plastic to suck up the colors. But this gives me the most definite line in a laminate. When I reheat the colors mix a bit. Quote Link to comment Share on other sites More sharing options...
smallmouthaholic Posted October 30, 2015 Report Share Posted October 30, 2015 I don't think anyone mentioned this but both colors must be of the same viscosity and type of plastisol. Put your injector and blending blockmin a toaster over to keep them both warm. I used to do that until i moved up to the Shooting Star System that eliminated the blending block and keeps the injector heated. Quote Link to comment Share on other sites More sharing options...
Frank Posted October 30, 2015 Report Share Posted October 30, 2015 (edited) Yes the temps must be within 10deg or less but if they are like 350&340 they will mix just like the photo. In this case the blending block has nothing to do with it as you can see he has both colors in the baits. Look at a mold real good and at the gate where the plastic enters it is like a nozzle. So when it is to thin it sprays in the cavity instead of flowing. Lower temp thicker plastic will flow thinner hotter plastic sprays/mixes at the gate. Look at most of the baits and you will see where the white crossed over just after the gate. Much less noticeable on colors that are transparent.

sticky Posted November 2, 2015 Author Report Share Posted November 2, 2015 I just wanted to let you guys know I shot some baits last night and they turned out a whole lot better. For it to work for me, I had to have both colors right at 300. I also took time to warm up everything in my oven really good. I just wish there was a set of smaller injectors available for those of us who shoot small baits. Once again, thank you all for the input. You guys sure know what you're talking about. One last question I have is where is a good place to get custom molds made? I want to get some cnc molds done for a project I've been thinking about. I googled a few places, but the only one I got word back from quoted me well over $600 for a 12 cavity 2 1/2" mold. Quote Link to comment Share on other sites More sharing options...

I googled a few places, but the only one I got word back from quoted me well over $600 for a 12 cavity 2 1/2" mold. That sounds about right. You have to realize that when you buy a stock off the shelf mold from any one of the mold makers, you aren't directly paying for the design time, they are banking on selling a large number of that particular mold. When it comes to custom molds you now have to pay a $250 - $500 design fee as well as the mold (which you will pay a per hour rate for machine time)Custom CNC molds aren't cheap.

Saugerman Posted November 2, 2015 Report Share Posted November 2, 2015 I too shoot my laminates at about 310 degrees, as Frank has stated. But I sometimes have a problem with them not adhering to each other. They sometimes can be pulled apart very easily. Do you reheat them some how for better adherence?

MonteSS Posted November 3, 2015 Report Share Posted November 3, 2015 Ya $600+ is right for a custom mold with design work included. Each additional mold should be normal prices tho. Try Bob Lalonde here or Baitjunkies 1 Quote Link to comment Share on other sites More sharing options...
