SEE-THROUGH MOLDS, Shooting Clear Lure Injection Molds To See The Injection Process 

Thanks so much for watching! Which one was your favorite to watch? Swirl? Bloodline laminate? Core Shot??

Replacement arrived!By the way, I did forget to mention that the original lure did have a decent strike however as most anglers will attest you can get a hit ru-vid.comUgkxCbNOWAGmn6nfbCbJDmasvBq7J38KZNw2 and fish will hang on and release lure. I used the replacement lure yesterday and ran thru a Shimano Waxwing, Kastmaster, Bobber (set to sink). I found the does run deep (I casting on the flats 3.5'). Make sure you adjust your rate of retrieve and rod tip angle (up) to prevent getting snagged on bottom. Used it a couple of times and action was very lifelike (looked like local bait fish for trevally), craftsmanship very good....however eyeball fell out. I asked for replacement and it is on it's way! It was very easy to change out treble to single inline hook.

What it looked like to me was that shooting the core has less to do with pressure and more with an arterial draw. That is why the upper ones tend to fill faster than the lower ones. If there is a flaw in the core then pressure comes into play. What was cool to see with the bloodline was the pearl purging the purple out of the belly and into the tail then the belly filling with pearl creating a nearly flawless laminate. A huge THANK YOU to Josh for covering his CNC machines with plastic shavings so that we could see this. Also a huge THANK YOU to both you and Josh for incurring the cost of this demonstration. The loss of production time and expense at AI just to produce these molds may not be fully realized by all viewers. 👍🍺🎣

On the core-shot that didn't fill all the way, I'd say the fluid pressure wasn't high enough to fill the bottom until the spru was about half full. In the slow motion video, you can see it tried to fill about half way through the pour but the material that hit the bottom of the spru first probably chilled, skinned over and clogged the in-gate to the bottom cavity. It happens a lot in the casting world and it's called a cold shut. The only way to prevent this is to build pressure faster, keep the material hotter/insulated or increase the in-gate size to lower the sensitivity of clogging due to chilled material/low pressure. You hit 2/3 on those options on the blue and clear core-shot. With 8 years of experience in the casting industry and a passion for fishing, this video was awesome. Great work!

The core shot worms are absolutely beautiful! I think that is one of the coolest things I have ever seen!

on the bloodline core shot, it appeared that the bottom one caught air and it became trapped in that bottom worm. Amazing to watch though!

That's awesome to see what happens inside. Thanks Chris

I cannot thank you and Josh enough for doing this. Seeing the way it works inside was fascinating and I think I have learned as much as I was simply entertained. Too bad the oil seemed to not work, those laminated looked great!

Cool video Chris and great idea. Thanks to Josh and Travis for awesome products (and top notch service)

Interesting to watch. I would like to see a follow up video of you using sprue extenders on your largest bait to see how the extender allows for more plastic to get sucked in. From the video you just shared, I don't see a lot of opportunity for the mold to suck in additional plastic even when you topped it off. There some back vacumm action when you pulled off the injector that you can see the plastic actually get pulled back out of the stick worm. That was neat. (the TPG Baits guy)

Really Amazing to watch the "internal" tracking of the injection process !!! Brilliant !!!!!

Imagine core shot flukes or small swimbaits. Lots of bait fish are somewhat translucent. Cool video.

The coolest thing I’ve seen on RU-vid. The swirl was my favorite. Thanks

That was awesome to watch the plastic flow. Great video

AWESOME video Chris. Nice work to you and Josh!

This is hands down the best RU-vid video I have ever watched

This has got to be one of the coolest videos I've ever seen on plastic bait making! The swirl was absolutely amazing!

Beautiful bait turned out! We also pour plastisol in acrylic forms, cheaper than aluminum! Only more clamps are needed, it turns out to be an environment at the lures. And it's just super !!!

I’m very new to soft plastic making but I’d be willing to bet that the mold cooled down the first bit of plastic enough that it didn’t flow well, where the plastic above that was contacting already warm mold (plus more thermal mass from the surrounding plastic). When using the Jann Netcraft molds, I found that before pouring the mold, I needed to dump a little bit out because the pour spout on the measuring cup was cool enough that the first bit of plastic would set way too fast. Dumping a little bit on the counter right before pouring brought the cup up to temp in that area and fixed the problem. I’m guessing that’s why the hotter temp filled out better. A deeper / larger sprue might let more hot plastic build up in the bottom before going into the first cavity. If it extended down past that first one another 1/2” for instance, you’d have a bigger volume of plastic built up before it starts to fill out, if that makes any sense.

Great idea! Answers a lot of questions. Love those core shots.....

I've had the Janns clear molds for many years. I got the first ones back in the late 70s and they still work fine. Yours are great.

You can see the swirls! The little spirals..... OH MY GOSH THAT GOD DANG LAUNDRY !!!😂😂😂😂😂 I’m dying! This is really freaking cool, great content Chris

Thats so cool! I am still amazed that the colors dont just mix together coming out of the block.

That was gnarly. I'm not a bit maker. So don't know all the new advances or anyting but I've never seen worms made with pins like that for second colors. That's super cool.

Wow that was really cool!! Also awesome that a company was willing to work with you to come up with this! I think it would be really cool to do the same with a blending block that way you could see how everything flows from start to finish.

This was a great idea! Super cool to see how it all works. I’m an industrial mechanic and we make plastic containers such as mustard bottles and oil bottles. Really cool to see how it works!

Hey Chris. Great intro! Loved it! OMG! Clear molds! How freaking awesome is that! It was awesome to see the injection process in action! Too cool! This is my 2nd favorite vid of yours! Thanks Chris! Thanks Angling AI! Fantastic!

That was so cool to watch. Thank you Chris,and Josh. Loved them all.

Great video Chris gave a lot insight on the injection process. Thanks for posting this video.

Oh man this made my day. As everyone else has stated that was really cool! Was every bit as awesome as I hoped. Thanks for going and doing this! I had done a bit of research on it and knew it could be done, but the material is pretty darn expensive.

The bottom one didn't fill, most likely because your runner was too wide, which created a higher pressure than what the air needed to escape. If you made the bottom part of the runner deeper, it may have filled. At 9:53, you can see the pressure equalize (the resin moves back), once you release pressure in your injector. Also, not sure why your mold is sideways, would be much easier and hassle free, flipped 90° facing up. If you need to keep this design, you should add vents (air escapes) on the opposite end of your parts, which direct airflow back to the top and out. Injection molding, these can be 0.025 mm (4-8k tons/in²), but since you're not applying a lot of pressure, I'd aim for 1 - 2 mm, depending how quickly your resin/silicone settles. It's easier to cut of the ends, than to lose a part. Which is another thing, not sure what resin you're using that it's exotherm'ing so quickly. If you're able to, I'd let it exotherm naturally, then post-cure it if you need the extra thermal and mechanical properties. In fact, if you're heating it on purpose, there's a chance you're losing properties. Also, a lot more expensive and harder to get, you could try polysulfone for your mold, especially one reinforced. You can get the Tg over 400F. If mold clarity is absolutely necessary.

Hey all, I actually have a degree in plastics engineering so I thought I would lend some knowledge. The top lures filled first because plastic is a non-newtonian fluid and it causes a pressure gradient from the nozzle to your end of fill especially with such a thick sprue.

Definitely awesome to see. Always wanted to know how it worked, Thanks.

Great video loved seeing the inner workings of injection shooting.

Just when I thought you couldn't possibly top your last video, you do. Excellent.

I think that u have some air that went in when the liquid was going in forming a packet at the end of the first worm but pretty cool I love it

This is too cool!..... I could watch this all day! Thanks

That was super satisfying to watch. I think the laminate was my fav. Thanks for the great video!

thats awesome! very cool to actually be able see how everything flows and fills the molds

Awesome idea Chris! Blew my mind away, coolest thing I've watched to date.

Pretty awesome! It was crazy watching the Laminate on the swimbait. The top purple color actually started to go into the belly some but once it was filled and pressure was applied it pushed it back. Very cool. Good stuff! 👊🏻

That was cool to watch. I love the core shots. I love the blue and the red cores in the clear plastic with flakes. Nice baits.

Very cool. Love the slow motions. Thanks for sharing.

that is flippin crazy! it would be a sweet mold to have, did you guys figure the cost difference between aluminum and whatever these are made from? diggin every video and this one was spectacular!

You need to bring these ones back man awesome molds

Is hard to pick a favorite because all of them were so cool to see

Amazing!!! Have always wanted to see it happen. Thanks for the great video

The core shot ...very cool thanks

Family time is the best time thanks for sharing

That was really awesome! I loved seeing the core shots the most, watching the little shells fill was pretty awesome.

Havent read thru all comments to see if its been mentioned but you may need to vent the end of the cavity to allow air to escape when filling. Otherwise you pressurize the cavity and it prevents the resin from flowing to the end. Common issue in traditional injection molding, especially when filling at extremely high fill rates.

I really love this idea. Great video chris. Havent watched in awhile uk life happens but im glad I jumped back on with this video

As a former bass fisherman, I absolutely loved this, loved the blue core... You should send this to Roland Martin, he does stuff like this as well and has some videos out there too.. Thanks for the video, I thoroughly enjoyed it..

Great video as usual. I loved seeing that swirl go in. Lookin forward to the next one!

They all was interesting. My favorite was the Blood Line. Thanks for a great video

You didn't want to use your fancy spray can lube lol. I don't fish over here in England,but I'm addicted to watching you make baits.ThankQ.TkEZ>UK

Amazing!!! I love the core shots. Thank you for taking the time to get with AI to make this amazing molds for this dimension.

That is awesome. I absolutely love the colors of the core shots!

super sick! love seeing how the injection process works fully!

What an amazing idea!

Chris, congrats to Josh and you on a great concept,well executed. Very informative

Great video, thank you for posting it! The blood line was my favorite. I've always wondered how they are done. I mold and build my own hard baits (spinnerbaits, jigs etc), but I don't do soft plastics yet. I'm thinking I'll start.

Lord have mercy the crawfish boil looked amazing lol and nice to meet u momma fishing live long and prosper😉😄😇😎

The clear and blue look so amazing, I gotta get my hands on those!

The core shots looked awesome

Awesome video! In the past when I have had issues with my core seinkos it’s always the bottom one. Makes a lot more sense after watching this video! Side note... so glad my laundry room is in the house!!! Haha!!!

Maybe because the injector wasn't hot the silicone cooled down. So when you injected it the already cooled silicon goes down and them gets cooled on the walls of the mold. So there's a chunk of silicone in the liquid that plugs up the last worm. But since the first bit of silicone already warmed up the upper part of the mold it was able to stay hotter for longer and stayed a liquid. I think heating up the mold and injector could help... The mold is plastic so it doesn't have a very high thermal mass but could still be warmed I think. It looked like the injector had some metal so that could be good for keeping the silicone liquid. Idk why that took so many words or if I made my points clearly but there ya go.

That was very cool. Hat's off to you and Josh. Great video

Idk what I was expecting it to look like but that's definitely not it lol. Its amazing to see what actually happens in the mold. Another Awesome video!

Definitely a cool process

really nice man however i dont know about useing the clear molds they are cool but i like what works best

simple the bottom one was the coldest. as you pour the upper ones are now insulated by the bottom thus retaining more heat which is more fluid and better able to flow throughout.

Great video,loved the core shot and bloodline laminate. thank you for all the effort and lengths that you go to keep us informed and entertained. my first 2 Angling AI molds will be with me in South Africa in 10 days time cannot wait to use them.

That was cool Chris thanks

Most likely the clear molds will take longer to cool the plastic. Try submerging the entire mold after shooting in some cool water before extracting. I think that should help the release.

Chris great Idea you and Josh came up with. I was wondering just like you about which core shot filled up first. I will be in touch soon my friend.

I’ve never seen a core of a different color. That’s pretty dope

Loved this video.... This was such a cool perspective to see.

So cool thanks for this Chris!

I'm guessing the top filled first because it is the closest to the pressure source.

Very cool Chris, my fav were the core shots. Thanks for the videos you make!

I work on plastic injection molds for a living making pvc fittings. Looks like you need to inject from the midpoint of the mold so that it is balanced. Just a suggestion

Swirls were very cool. Thanks for the video

Really cool to see how the injections function, but yeah the material clearly doesnt absorb the heat from the plastic like metal can, that's probably a major reason for the sticking. Nice little project but definitely not very practical

I really liked them all . pretty fascinating .

Great technical video, it is weird how every time the cavities fill at a different rate.

Molde e fantástico o melhor que ja vi da pra ver se o preenchimento ficou completo Parabéns! !

Now that was AWESOME!

Awesome perspective

I won't lie I'm really upset at myself, I really wanted to be the first to try this. If you want it to really work then use Pyrex glass, they can take the high temps cause it's clearly used for cooking but the big question is how well they would do in a CNC machine which I assume will be be okay. I love the slow mo work. Thermal Dynamics and fluid mechanics explain it, I really want to see the flukes as a darker Arkansas shad with a black jewel on the side.

really cool to watch thanks for showing us!

Totally awesome! I have the same laundry issue!

Great demo, the swimbaits were the best to watch I'm gonna have to order that mold now

The clear molds really give you a good look at how the plastic flows. But I have a question about these types of molds and the air. For stick worm for example. It fills bottom to top, left to right when its hot enough. As it is filling in from the left where does the trapped air stuck in the tips/right side go? I don't see it pushing out the fill end. Or is there enough space in the mold that the air can escape the cracks but the plastic is too thick? I don't see any sprue holes like you would on a hand pour closed mold.

Core shot is the coolest thing ive ever seen. Keep these awesome videos coming

not a plastic expert, but i do have some metal casting experience. It looks to me like the riser is a little too large for the application. The plastic seems to gel far quicker than metal would, and you are applying pressure to inject, not relying on gravity to fill like a metal mold would. I think performance of swirls and core shots would be better with a smaller riser.

This was an awesome episode. Always find myself coming back to it 🤙🏽

Those Excalibur mortars are awsome I had like 15 tubes set up at once it was crazy

Wow! That's amazing. My favorite was the bloodline laminate. Great video, very informative. Love AI molds.

I have a couple Ideas for some stick baits using those core shots. What if you didn't fill the cores but instead dip the ends in melted plastic then water so just the ends get capped off and the rest is hollow so they float better. You could also try filling them with something that bubbles in the water like those bleeding tube rigs.
