Swirl Colors

Recommended Posts

Two ways to get it. One is to take off the top cross bar and pulse the injectors one at a time . Two is to loosen the top cross bar and pulse this will give you a tighter swirl. The second ways is easier to fill the Twinjector otherwise you have two handles to fill one at a time. Frank

Are you saying the picture does not look like a swirl or you dont call it a swirl. Cause they all look a bit differant or is it my computer? But if you want something that looks like the picture the way I said to do it will do that. There will be no change of direction just pulsing from one to the other. And no you dont have to run around your mold while injecting but them that may be a swirl. Frank

maybe CarolinaMike can chime in here but i believe i remember him saying that swirls are achieved by alternately pulsing each nozzle on the big machines. you just have to find that sweet spot with each mold.

Big Daddy, swirls or pulse laminates (as it's known in the industry), are achieved by alternating from one color to another. To get anywhere close to a machine made product you will have to have a twin injector with a single nozzle going into the mold. The reason I say this, most pulse laminates are done in tenths of seconds. So, in other words, one color shoots for let's say three tenths of a second, then the other shoots three tenths of a second. On a machine, this will alternate back and forth for as long as I need to fill whatever size cavity I'm making. Some run as long as a minute, and then of course there's cooling time. But I think if you practice, you can get close to what you want. My suggestion is when you're sure your cavity is full, hold continuous pressure on both sides for a few seconds to take care of any dents you might get if you're using a soft plastic.

How long (time) do you have to do this (pulsing)? Looks like the plastic would cool off and plug the nozzle. At lease that's the problem I have.

Gary, That will be one of the problems on replicating a machine produced bait like this. Although the baits shown in the picture shouldn't be so hard that you couldn't get close. This application by hand is just going to take a lot of practice. Remember like I said, the machine does it in tenths of a second, but doing a single cavity you may be able to get by by doing 1 second. But yeah, your plastic will have to be hot to keep the bond intact. I've seen some swirl work by hand and some guys do a good job at it, but keep your eyes out, cause there will soon be a different way to do this. Be patient.

It is more of a continues movement than a pause and go. Let me ask how long can you inject before it clogs. I would like to know. I can empty out two 6oz injectors and the block will still drip at the end. I dont pause much. Frank

If you stop injecting for a couple of seconds, it will clog up. Now this was with a jacob injector which has a small opening to start with. Haven't tried the dual injector so maybe its something that won't come into play.

I had him make me a tip with a bigger hole and it works much better. I use the smaller one to inject his molds. The Twinjector has a much bigger hole. Frank
