hpssports Posted November 18, 2016 Report Share Posted November 18, 2016 I just purchased a one of a kind finesse production mold & I'm having problems with denting. I know the problem is coming from the gates being small. What would be the best way to make the gates bigger other than just spending all day cutting them out with a grinding stone or cutting wheel. I know that's probably my only option but does anyone else have any other suggestions? Quote Link to comment Share on other sites More sharing options...
Baitjunkys Posted November 18, 2016 Report Share Posted November 18, 2016 Believe it or not, I cut back my venting on a stick bait mold, and it dented like a sob. I went back to the .375 spacing on the vents and it cured it. Same exact gate. To answer your question tho, A small jewlers round file works best for me. 1 Quote Link to comment Share on other sites More sharing options...
hpssports Posted November 18, 2016 Author Report Share Posted November 18, 2016 My problem is that when they cut the mold they made the gates long & small diameter. The gates are probably about 1/4 inches long. I need to take some pics. Quote Link to comment Share on other sites More sharing options...
FATFLATTIE Posted November 18, 2016 Report Share Posted November 18, 2016 Did they not shoot the mold before they sold it to you!? I'd I'd be a little upset about paying the kind of money a custom mold brings for one that dents. Quote Link to comment Share on other sites More sharing options...
Frank Posted November 18, 2016 Report Share Posted November 18, 2016 Did you try and lower your temps below 300 and hold pressure? Might work for you. Another thing to try is demold way early and throw them in water to cool. This is a real pain but works on big swim baits. Quote Link to comment Share on other sites More sharing options...
Baitjunkys Posted November 18, 2016 Report Share Posted November 18, 2016 hawg it out with a dremel. just stay away from the actual gate. then use a file on that. Quote Link to comment Share on other sites More sharing options...
hpssports Posted November 18, 2016 Author Report Share Posted November 18, 2016 It was actually bought at a company liquidation. It was a prototype bait they were working on before they shut down. I don't have allot tied up in it as they did. I'd just like to get it to work. Quote Link to comment Share on other sites More sharing options...
hpssports Posted November 19, 2016 Author Report Share Posted November 19, 2016 I opened the gates on the first six cavities & they shoot great! Now just fourteen more to go. lol Now the only problem I'm having is that the aluminum gums up the grinding stones really fast. 1 Quote Link to comment Share on other sites More sharing options...
smallmouthaholic Posted November 19, 2016 Report Share Posted November 19, 2016 It was actually bought at a company liquidation. I wonder why it doesn't work. Unfortunately,you got what you paid for. Quote Link to comment Share on other sites More sharing options...
mark poulson Posted November 20, 2016 Report Share Posted November 20, 2016 I opened the gates on the first six cavities & they shoot great!

I even tried a metal burr tool, but the aluminum was too hard. I had a genius idea to add some extra detail to one of my molds. Doh!!!

rayhorse Posted November 20, 2016 Report Share Posted November 20, 2016 Hi everyone I recomend to make a Try shooting at more temp on your plastic, hold presure for 20 seconds and make sure your stirrer is on. The best mold cooling is from tail to bait head and runner on the last cooling order. Considering the number of cavities, you may have a 7 or 9 inches long runner, if this is right you may have more denting on the lower cavities than the upper ones, you would like a thicker runner than your bait diameter. On a milling shop you can get a nice modification. Show some pics of your mold, I´m sure there are a bounch of things for making it work better. Tacke care. wich is the diameter of the runners? how thick is your mold plate? Quote Link to comment Share on other sites More sharing options...
