Bodysix2 Posted April 5, 2019 Report Share Posted April 5, 2019 Just received my BTS stick mold. I choose to go with the top ports and individual shots. I went to go shoot some today and the ports are too large for the tip of the injector to sit properly. This is causing huge issues when trying to shoot plastic. Also, seems like when i go shoot the second port air gets into the first shot and pushes the plastic out. I clamp the crap out of it. Any suggestions?

Apdriver Posted April 5, 2019 Report Share Posted April 5, 2019 Dang. What injector are you using? Quote Link to comment Share on other sites More sharing options...

Apdriver Posted April 5, 2019 Report Share Posted April 5, 2019 Well, shoot. It’s pretty dang simple. The standard is 5/8 inch and one or the other is off. If the BTS injection port is too big, communicate that with Bob and send it back. If your injector is off, well call Sarah and do the same. That prob is hard to fix and you shouldn’t have to. 1 Quote Link to comment Share on other sites More sharing options...
Bodysix2 Posted April 5, 2019 Author Report Share Posted April 5, 2019 It’s not the injector , I have four other molds , three custom and another from BTS all fit well. Hopefully bob responds to my email. Quote Link to comment Share on other sites More sharing options...
Apdriver Posted April 5, 2019 Report Share Posted April 5, 2019 Yeah, he was just off with something that day. He should make it right. Quote Link to comment Share on other sites More sharing options...
Bodysix2 Posted April 5, 2019 Author Report Share Posted April 5, 2019 I ended up measuring the port size. The 5” sticks ports are anywhere from 1/16 to 1/8 bigger from the other molds I have. I think because of the bigger ports it making the walls in between each port very thin allowing air to get pushed into the ports when shooting.

Baitjunkys Posted April 5, 2019 Report Share Posted April 5, 2019 well top port stick is designed to be hand poured. Probably why it has a big port. If injecting IMO top port is the worst thing a guy could use. 1 Quote Link to comment Share on other sites More sharing options...
Baitjunkys Posted April 5, 2019 Report Share Posted April 5, 2019 Air is pushing in because it cant properly vent out, but rather vent into the other cavity, not a issue as much hand pouring as designed to do. 1 Quote Link to comment Share on other sites More sharing options...
Bodysix2 Posted April 5, 2019 Author Report Share Posted April 5, 2019 Well that makes sense now, but hand pouring laminates will be terrible. Reason why I got the top port so I could shoot single shoots. Well that sucks. Quote Link to comment Share on other sites More sharing options...
Apdriver Posted April 5, 2019 Report Share Posted April 5, 2019 That does suck. Never thought about it being hand pour as most folks have moved away from it to hand injection. 1 Quote Link to comment Share on other sites More sharing options...

Bob must have thought you wanted a hand pour for some reason because very few of his molds are hand pour. You can still do laminates with that mold the old fashioned way: open the mold, pour one side, close the mold and pour the other half. Personally I prefer side inject for sticks. In my mind, the salt,sand, whatever would tend to sink towards the tail in the vertical baits making them a tad tail heavy as opposed to the side inject where it would tend to sink towards the side of the bait evenly along the length of the bait. I could be all wet in that theory but in my mind it's possible. 1 Quote Link to comment Share on other sites More sharing options...
Bodysix2 Posted April 5, 2019 Author Report Share Posted April 5, 2019 I wanted a top port with individual shoots to make laminates. This way I don’t have a giant spruce that gets trashed. Also, I was thinking the single ports would make a better laminate. Yea, I’m not going to hand pour. Before I placed the orders I specifically asked Bob the different between a side and top injection. No mention the top was going to be cut for hand pouring. Plus his description says top inject or side inject nothing about hand pouring... Just frustration as I waited almost 25-30 days after the order to receive the molds, never bugged them to see where the order was. Guess I’m out of $70 and now the tip mold I have is useless unless I buy another stick mold from him. Quote Link to comment Share on other sites More sharing options...
bryanmc Posted April 5, 2019 Report Share Posted April 5, 2019 I'm sure he'll work with you on it. If it was intended to be injection the sprue was obviously cut incorrectly and I imagine he'll re-cut the mold for you.. 1 Quote Link to comment Share on other sites More sharing options...
Baitjunkys Posted April 5, 2019 Report Share Posted April 5, 2019 Im sure he will as well, but in theory you have 4, 1" top ports, or you have one 4" side port. you really don't save any material. I think side port shoots much nicer laminates myself. as it works more from pressure not gravity. 1 Quote Link to comment Share on other sites More sharing options...
SlowFISH Posted April 5, 2019 Report Share Posted April 5, 2019 For my own learning (as I've made all my bait molds and with few exceptions design them with a single top port and run the bait "vertical") when shooting a "side port" laminate... are you using a blending block? If so - I assume the port is on top of the mold and the bait running "horizontal"..... any issues with the colors not being somewhat even as it fills the injection port then has to "turn" and fill out the bait horizontally? I'd imaging if you don't have the block registered correctly obviously that would be an issue... but otherwise does it work pretty well? Thanks!

Bodysix2 Posted April 5, 2019 Author Report Share Posted April 5, 2019 It doesn’t work with a blending block or a single injector. Like someone said before I strongly believe the ports are made for hand pouring. 1 Quote Link to comment Share on other sites More sharing options...
Vodkaman Posted April 5, 2019 Report Share Posted April 5, 2019 It looks to me that a final skimming operation was omitted, making the mold halves thicker than design. The resulting uneven contact surface causing leakage between cavities and a sloppy fit of the injector in one direction. Dave Quote Link to comment Share on other sites More sharing options...
Baitjunkys Posted April 5, 2019 Report Share Posted April 5, 2019 Most mold makers face first not last, And the holes look round which they should as they are clearly drilled out post, hence the chatter marks at the bottom. 1 Quote Link to comment Share on other sites More sharing options...
Bodysix2 Posted April 5, 2019 Author Report Share Posted April 5, 2019 Bob did confirm he made it for hand pouring and we’re working out getting a new one. Thank you everyone for the help. 2 Quote Link to comment Share on other sites More sharing options...

Those holes are programmed in the mold half. They are done with a ball end mill. No chatter just a large step over. That’s the way some of the early molds were done. I have many molds like that and most are hand pour. Not that they can’t be injected but they have some issues when doing so. On the question of saving plastic from a long Sprue you will have four short ones and when making sure they are topped off I would bet you are wasting about the same amount of plastic but wasting time keeping them full. 2 Quote Link to comment Share on other sites More sharing options...
