Zyonb Posted April 20, 2016 Report Share Posted April 20, 2016 Do you need an injector for a two part mold? Or can you just pour the plastic in from a measuring cup..? Quote Link to comment Share on other sites More sharing options...
Frank Posted April 20, 2016 Report Share Posted April 20, 2016 Some of the older ones you could hand pour but most nowadays need to be injected. If you can hand pour it will say that in the description when you buy. 1 Quote Link to comment Share on other sites More sharing options...
Zyonb Posted April 20, 2016 Author Report Share Posted April 20, 2016 If I wanted to make a two part plaster mold and I want to hand pour it do I need to make any design changes? Quote Link to comment Share on other sites More sharing options...
gone2long Posted April 20, 2016 Report Share Posted April 20, 2016 The real issue you have is in the detail if its just a large cavity without detail and appendages like stick baits and the like then most often it can be hand poured but you will find yourself very frustrated if you put claws, legs and the like into it. 1 Quote Link to comment Share on other sites More sharing options...
ipt Posted April 22, 2016 Report Share Posted April 22, 2016 i make 2 piece hand pour molds from POP all the time, you just need to make sure gravity will fill your cavity. also everything needs to be thick enough to keep plastic flowing without cooling off. send me a pic or more details and i'll have a pretty good idea for you.
