Tutorial: molds and Resin copies 2 part

This topic is published with the intention of giving useful informations to those that want to start using rubber molds and resins for casting figurines or other objects to be customized. I will take as a sample some characters from my collection of superheroes.


Given the assumption you got a mold now, let's cast.

You need: two-components resin, 3 plastic glasses (1 for component A, 1 for B and 1 for the mix of A+B) and a plastic stick to mix A and B together.
Fill equal parts of A and B in 2 different glasses
Pour them together in the third glass and start mixing with the plastic (or wood or iron or the hell you prefer) stick for 10-12 seconds. Don't stay longer or the mixed resin will start to react and harden before you cast. 10 second of vigorous mixing is pretty enough!!

Fill your molds

 Fill the mold, give time to resin to penetrate and fill more until resin appears at upper parts


Check the resin is coming from air channels also or you'll have air bubbles in the hands, nose, chin and in worst cases some arm or part missing!!
Do not move, rotate, manipolate the molds while resin is hardening, or you'll have "double lines" effects.
Just wait. Give the time to the resin to become hard:
After 5-8 minutes you could already extract the cast. the Prochima suggests to extract after 30 mins, but I'm maniac and rush... rush... rush...

take them all!!













hope this second part was useful for you, if you have any further question, just ask, I'll be glad to modify this post in order to reply as much I can to all questions.
Hope this will give you the motivation to start your "custom" hobby now and to realize yourself all the characters that unfortunately the collection has not issued.

Time for final balance:

Never forget to remove the resin hardened into the air channels before the next casting!!
Casting fins are really easy to remove from the copies as they can be cutted with a cutter or even with your fingers.

If you found this topic useful please feedback me, I would like to start also talking about different resins I experienced and modeling materials also.

  3. non faccio il modesto, io parlavo principalmente della facilità con cui ti muovi tra gomme e esine ti assicuro a me risulta molto difficile e faccio casini enormi, poi si sono rovinati quasi tutti gli stampi che avevo e mi sono ridotto a fare la basi dc per me e le marvel speciali per spidey :-)
