CNC FREAK

OK thanks Frank It's for the European market, not the USA.

Hi, i would need the raw materials to produce motoroil(changeable) in a huge amount to create several motoroil colors. Drum size is not a problem. Anyone got an idea where i could buy these ? Many thanks.

hi slowfish thanks for the FASTresponse -> fastfish understand about the vents, i'm going to try that ! i inject each bait seperately vertical because i wanted to make perfect 2 color laminates At the moment i have 2 twisters in one mold, using the blending block i inject the 2 baits seperately. i could inject these horizontaly and inject from the top, that should work also for laminates but i think, if i want to have perfect laminates i can only inject one bait at a time. Possible to make a multi cavity laminate twistermold ? i think the plastic will be mixed up....

i have a small problem with a twister mold the U-shaped ribs of the body are not completely filled with plastic. when i inject fast i have this problem, i guess air is closed in so i inject very slow, the result is better but the problem is not solved. Dont know how to solve this problem... The injector hole is 5/8, the conical shape of the injection channel on the drawing might not be perfect for a 2 color laminate. Done some tests and the colors are mixed up. Does anybody know how to get the bodys FULL with plastic ? Thanks !

Caney Creek molds has a product to sink baits : "HDS Additive is a naturally occurring silicate formulated specifically for use in making soft plastic baits sink" mhh does anyone know what kind of product this is ?

i use a digital microwave 800Watts, i heat up the plastic combining full power with 30% power plastic is cristal clear without stirring (only shaking the cup a few times) i reheat on 10% power, works perfect to me i think some microwaves have a program that is perfect to keep it just hot enough and dont overheat

have tested my new blending block today !!! problem solved ! have made some very nice baits...i'm happy

Bob, that sounds good and would be happy to give it a try i can make the block this week and post the results i have read your message several times but i dont get it can u draw me a sketch on a piece of paper and post it please?

Have just made my brand new blending block and it looks perfect ! the 2 colors channels are coming together in the mold and not in the blending block like my previous one keep my fingers crossed, tomorrow i'm going to test it !!! and i'm going to design some blending blocks for swirl effects...!

i'm going to start with making a new blending block not sure if this might be the cause but if will give it a try my block has an aluminum insert tube, the colors come together before the plastic gets into the mold i have made some nice laminates before but i will change it anyway

just shot some baits at 340+ same problem BUT i discovered that every time, after sucking up the plastic and moving them out of the plastic to the blending block, the injectors are dripping. Not a few drips, its a fine stream maybe this dripping is getting into the blending block and cause the mixed problem have done a test and as soon as i remove the injectors out of the plastic i hold the tip up and than quickly put them into the blending block. The result is much better but still not perfect. i think i need to solve this dripping problem and test again with several temps of plastic have checked you tube and this dripping seems to be normal

Hi Frank sorry i forgot to mention that my 2 injectors are combined. They can not be pushed individually. They have a thick wall so i pre-heat them. i suck up 2 colors at once, put these in the block and inject the mold. Works perfect but like you where saying, to get it perfect several things must be perfect. i'm using 2 microwaves for the moment, my thermometer is working to slow to measure each color fast so it's not that easy to get the 2 colors perfect the same temp i will start to set up 2 presto pots with a digital temperature regulator so i have perfect temp control i'm not sure but i think my plastic is to liquid. am i right that if the plastic is very liquid a laminate is difficult or not possible ?

everybody thanks for the response/advice ! today i have done some shots, this time i used a digital thermometer and heated the plastic to 310 no succes so i heated another time to 320, same result tried 5 more times without a proper laminate enclosed a picture to see the result could it be possible that the "rounded ribs" in the mold are causing this problem? a few baits have a body that are quite ok but most of the baits have also a mixed body ! i'm using 2 single injectors with a blending block. its a single bait mold, i shoot in from the head of the bait, so i'm not using a multicavity mold and shooting from the side. As soon as i get this one to work i will make a multicavity model. last week i have injected another bait/mold with perfect result so my injectors/block are ok to me. The only way i get a perfect laminate is when i shoot in 2 steps, first color 1 with a plate, remove the plate and shoot color 2. Perfect bait but to much work... ow boy what is going wrong

the bait is completely round like a stick bait, nothing special to me. both sides of the mold are the same... will upload a picture tomorrow i guess the plastic temperature must be the problem i tried 5 times, heating some plastic in the microwave... none of the baits are ok shooting in one color and painting afterwords might be easier

i have made a new mold of a twister with a standard curly tail the body of the twister is about 1/2" in diameter and 2 1/2" long the tail is 2" in diameter , thickness 1/10" when injecting 2 colors with a blending block, the color of the body is ok but the color of the tail is completely mixed up. i have tried to inject fast, inject slow, doesnt work. also tried hot and thicker plastic my injectors are very hot this i not a multi cavity mold, only one bait (its a prototype mold) my blending block works perfect... for some reason i can not make a perfect 2 color laminate help....

i have plastic from www.brightbaits.com (europe) have tested from several company's, the best so far phtalathe free, cristal clear, less fumes,no airbubbles, no yellowing

how does a heat exchanger looks like for this kind of use? anyone got a link ?

Thanks Dave for the advice, its clear to me know, square pots are not ok i will use round pots

good idea mark, thanks i'm thinking about how to heat this beast i would like to have 2 pots of 5 quart plastic

well, i have made several injection molds this week and it works perfect but u need to use release agent like silicone oil before u inject the baits not every time, i repeat it after 3 cycles for me its perfect for making prototypes as long as i get waste material for free I dont have any problems with melting. But i dont use these for mass production, therefore i will use aluminum. however its not that easy to get it where i live, people who are using it for furniture, kitchens, save the small pieces because u can glue it to each other without any gaps. Buying this stuff NEW is no option, way to expensive. So tomorrow i'm going to check if i can find some other kind of material to make prototypes. I'm thinking about POM, Polyoxymethylene But i expect it would be more expensive than aluminum. texacan84, it would not be possible to make your mold, i'm from Europe. Price for shipping would be to expensive. Sorry mate,i'm sure there a lot of people in the US who can do that for u...

i was suprised of the high price for the band heaters... but ok maybee its better, i was thinking that bandheaters would heat up the liquid much faster because the contoursurface of the pot is bigger than only the surface of the bottom i'm thinking about using square pots in thick aluminum that holds the heat square pots would be easier to screw to each other, also easier to make the 2 color injection system at the bottom because i could place them closer to each other than with round pots i'm placing 2 automatic stirrers at the top, dont know if mixing in square pots would be a problem

does anyone know how this machine is heated ? bandheaters ? how much watt ? i think the pots are square and not round ?

can anyone send me pictures of the heating elements and how the control works of the handles thanks !

i'm planning to make an injection machine for large production i have seen the jacob baits injection machine but i need something bigger something to create thousands of baits/day i was thinking of 2 pressured pots with high volume plastic has anyone knowledge about this ? some tips ?

Thanks Bob for the picture !i understand perfectly HERE THE GOOD NEWS i made the runner bigger and problem is solved !!! thanks bait nr 2 and 3 are perfect bait nr 1, the nearest at the injection hole has a small collapse but i think i know how to fix it i did not expected that i need that big runner when i started drawing this mould has anyone expierence with "Corian" , "Hi Macs" composite material ? i have made some awesome moulds, smooth surface and much higher cutting speeds than aluminum. Its expensive but i get some waste material for free. I spray some silicone oil in the mould and they come smooth and glossy out of the mould. The advantage of this material is that u can SAND it easy and POLISH it If i need a thick mould i glue blocks perfectly on each other without seeing this, after milling it looks like one solid block I was wondering if this mould would work perfect to make laminates, 2 color baits. With previous test (small runner) bait nr 1 was not perfectly shot in 2 colors, bait nr 2 en 3 perfect 2 colors in the middle. any advice about 2 color injection would be GREAT. I So i will make a new mould tomorrow and give it a try ! thanks guys
