Hi everyone, Other option is to polish the senko mold. You will need a dremel a bounch of rotative felts and a polish paste for aluminum molds. After this You can get a very nice and smooth finish on your senkos.

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?

I would like to try this one

Hi every one, I really love the presto pot, is very cheap compared to a kitchen canister with a band clamp heater. I mean cheap in price and energy consume. I have two presto pots controled by 2 "my pin TA4 Pid " and a J type thermocouple. I weld a square pice of aluminum with a 3/16 hole to the bottom side presto pot for the thermocouple, this is to get the thermocouple tip in contact with the Pot wall. You may wire the 110 current on a direct way or make a very easy trick on the presto temp control. You can make an special pot or machine base that allways let you fix your pot or machine in a 45 degree position for small batches or 90 degrees for large batches. There are some little electric pots for fondeu on target or wallmart and I'm shure there is a way to control it with a PID .

Hi guys. For plastisol baits aluminum is for me the best choice. Like slowfish said nowhere near the ability of aluminum to dissipate heat, and if you add cooling to your aluminum everything will go faster. About machinig aluminum I prefer slow and non deep cuts, it will take more time to finish but I will save endmills and I could leave the machine almost alone without worry about broken endmill.

Less pigment on your plastic and Baking soda should works.

I build and inyection machine, it holds 15" x 17" molds, 2 color inyection, laminated, swirl and core. I could do 30 5" stick baits per shoot.

Do you have your own production molds? I have my own inyection machine shooting 2 different molds for now.

Hi every one. Does this happened with all your molds? How much plastic is in the pots when you shoot? 2 cups? Half or full? You can reach for the bubbles in your inyector, load you inyectors with half plastic and let them cool, tacke out the cooled plastic and look for the bubbles. The hand inyection proces is a never acurate proces, I mean, plastic temperature, inyection presure, cycle time, inyector position, mold temperature never is the same , etc, etc there are a lot of things to control.

It is in there, without heat stabilizer nothing works. Soft plastic get stained very fast.

Use hig temp automotive silicone, make some little strings or balls with the black silicone, let them dry and cure, then add the balls and / or strings to your plastic and inyect. This happened to me when some silicone strings release from the seal of my inyection machine. Greate black spoted effect over watermelon

Hi everyone,A hand core inyection proces could work shooting the half of plastic on a single cavity, close the sprue of the cavity with a cork plug or any other kind of diy plug, give some 180 degres half turns to the mold and stop after plastic get solid like roto molding proces. This should result in a hollow bait. Now open your mold and see if you need to cut the tip near to the sprue for the second color.

I'm doing my own pigments in Mexico, for this situation you can use a baking hand mixer, add some worm oil or softener to the hard rock pigment and mix for a long time. After mix store your pigment in wide containers, butter containers work fine. Next time it will be easier to mix.

5/8", you may consider a runner diameter bigger than your bait diameter.

I tried to quote the zorn, machine, but never answered me. So I decided to build my own soft plastic injection machine. this machine can run 12 "x 15" zise molds, this is about 10 lizards of 5 " or 24 stick baits of 5" per cycle, solid colors, laminated, swirls and chrtreuse tails. it requires 120v and 220v AC. It takes about 20 minutes to cool down, other 20 minutes to change the color and 2 cycles for purge hot runers.
