Bassinfool Posted February 8, 2017 Report Share Posted February 8, 2017 Is it the CNC or sand casted mold? If it is the CNC you shouldn't be having any issues with shine unless you're not cooking your plastic to 350 degrees to fully convert it which can lead to cloudy and tacky feeling plastic. The sand casted mold will not give you the very shiny appearance that a CNC mold will. You can modify it using high temp engine paint. There are several threads on this site detailing how this is accomplished. Quote Link to comment Share on other sites More sharing options...
MonteSS Posted February 9, 2017 Report Share Posted February 9, 2017 Buy the aluminum cnc mold from Baitjunkys. The Do-it mold is not designed properly for us home injectors. And yes the Essential molds are all dull and textured like that. Quote Link to comment Share on other sites More sharing options...
mark poulson Posted February 10, 2017 Report Share Posted February 10, 2017 I am a hobby pourer, and use a hand injector. I hand inject my two Essential 5" senko molds all the time, and they shoot great! I wish they made more Essential molds, because I can afford them.

Tiderunner Posted February 11, 2017 Report Share Posted February 11, 2017 In the video he masks off the mold area. I couldn't be bothered. We're talking a layer of paint a couple of microns thick. I also used clear engine paint. Makes it hard to see where you painted. Using color might be better. There are also other auto paints that can handle higher temps. After about 4 coats, I scuff the flat areas lightly with sandpaper to remove those couple of excess microns. I've made a couple hundred without having to recoat. My senkos come out super shiny. I also have the CNC mold, and I hate to say it, but at times it seems the essential mold works better. But what a difference in quality of the molds. 2 Quote Link to comment Share on other sites More sharing options...
Heelfan Posted February 17, 2017 Report Share Posted February 17, 2017 I just painted the same mold and After some trial and errors ended up using VHT high gloss engine enamel. Put three or four light coats let air dry then cure for 30 minutes in oven at 200 degrees per there instructions. Now it is super slick. Unbelievable the difference.
