New to pouring

So i been pouring my own lead weights amd jig heads, and tying crappie jigs for a while. Just orders a bunch of stuff to pour plastics, or try. I added in to my workbench in the basement to add room fro microwave and all that. I got the pyrex cups, microwave, and everything i think ill need. Does anyone have any advice to offer? Any dos or donts i should know before i start? I do have one question. The molds i have seen, looks like you inject the plastic into it, where does the air go thats in the mold cavity? Id think it would have to have and exit or vent and one would pour till it came out or something. Or im thinkin too much lol

Injection molds are vented and the vents can be almost invisible. They are there though.

If you are doing this in a basement, be sure to do it under an open window with a fan blowing fresh air over your work area and another forcing air out another open window.. The fumes from the cooked plastic are not something you want to stand around and breathe in.

Make darned sure you get a digital, probe-type thermometer to check your plastic temperature while cooking it and read it by holding the probe in the center of the plastic mass in the cup, not touching the sides or bottom. Be sure to break up the cooking time into shorter bursts - like 30 seconds, stir, 30 seconds and stir again until you reach the 350 degrees for full conversion.

I ordered everything from do it molds. My basement is a walkout, so i have aalk through doors and a overhead door for ventilation. If it goes well i can add a stove range hood and vent it outside. I do a lot of welding and fabrication so the safety items are taken care of already. Is a lrobe type or infrared thermometer better?

Welcome aboard sure that you will find this form very interesting and you will have definitely a lot of information here on this post. just make sure in your basement that your ventilation is good enough to carry all the fumes out of the room.
you have picked a good choice with do-it I'm sure that you are going to like their plastics in the molds that they do offer I hope that you will enjoy your new hobby and hopefully that we will see you posting some a year plastic baits on here shortly. there are stickers on the top of this form please read the safety one for sure please feel free to ask all questions I'm sure his guys will definitely answer all of them.

I had ordered a catalog from do it, and they sent a 25% off first order, so i saved about $350. Im pretty excited to get this started

Have fun with the hobby and stay safe. Burns hurt!

Get a probe type thermometer. Do-It sells a dandy in the plastics section of the catalog. About 16 bucks I think, maybe wrong. Page 132 of the paper catalog.

Always wear a long sleeve shirt and good gloves. Like Shipsahoy41 said burns hurt and are deep. Dave
