hey guys...i've been making molds for a long time now and have never had this type of issue. was wondering if anyone else has or at least has an answer.
im making a 2 part mold of 2 humvee tires. im using a form of alumilite to make the casting. it has the same 2 1/2 minute set time as alumilite. i have a 3/16 sq pour sprue and a nice size air vent. i've made 12 attempts and each one fails me in that the mold wont fill all the way b4 it pours out of the top of the sprue then wont "fill" all the way. i get 1/2 moon tires. i'm not upset but getting really frustrated with this. the mold itself came out great and short of not having enough casting resin for my first try...the first try really came out great (except the 1/2 moon thing). HELP PLEASE ANYONE?????!!! thanks guys!
