Vols824 Posted December 7, 2011 Report Share Posted December 7, 2011 I have been hand pouring for the past 2 years and really wanting to step up to injecting. A simple question that I cant find the answers to after searching: 1) Do all the injection manufactures fit every mold or do you have to stick with that brand molds? If not are there adapters out there that make this possible. I have also seen reference to blending blocks? Whats the purpose of these? Thanks Guys for the help...This is a great site for learning Quote Link to comment Share on other sites More sharing options...
Jig Man Posted December 7, 2011 Report Share Posted December 7, 2011 I only have 2 injectors but have 2 tips for each. They came from Bear's. I have to have an adapter to fit some of my molds. I have a blending block which allows me to do laminates with some of my molds. Quote Link to comment Share on other sites More sharing options...

smallmouthaholic Posted December 8, 2011 Report Share Posted December 8, 2011 All of my injection molds have a 5/8" diameter port. Lubricating the inside of your injectors w/ Pam makes them slide much easier. Two color inject takes time to master. The injectors ,blending blocks and molds must be pre-heated for optimum performance and consistency in colder climates. Both colors of plastisol MUST be the same temperature and viscosity for good laminates. I use 3-4 different blending blocks when injecting 18-24 molds @ one time w/ two colors since the blending block coagulates 1st preventing multiple molds being injected in one round. Two color,hand injection is a learning curve for sure Quote Link to comment Share on other sites More sharing options...

When I first bought my twin injector I would get more of one color than the other color and it didnt come out right. I think it might have been Frank who is on this site that told me that both injectors have to be within 10 degrees of each other in order to make a good laminate. Example one injector might be 345 degrees so the other injector needs to be the same or within 10 degrees of that temperature. I bought a laser thermometer off of Amazon.com for about $25 and I have not had a problem since. Quote Link to comment Share on other sites More sharing options...
