Molding and Casting

Group assignment requirements

The group assignment for this week is the following: - Review the safety data sheets for each of your molding and casting materials
- Make and compare test casts with each of them
- Compare printing vs milling molds

Material 1: Graffiti Resin Multi Use

Safety Instruction:

• Keep out of children’s reach.

• Store product in a dry place, preferably in the sealed original container, at temperatures between 20c & 25c.

• Do not swallow. If you swallowed the resin, call a doctor immediately.

• A face mask should be used for pregnant women while using product.

• Wear protective gloves when you use the product.

• In case the product comes in contact with eyes: rinse cautiously with water for several minutes.

• Caution: contact with contents may cause an allergic skin reaction.

Process steps:

Property Details
Mix Ratio (if applicable) A (resin):B (hardener) = 10:6
Work Time About 40 minutes
Cure Time 8 to 12 hours
Demolding Time Preferably remove from mold after 24 hours
Cured Material State Transforms from liquid state into solid form

Graffiti Resin Multi Use

Process Steps:

Step 01: Preparation of Materials:

We started by gathering all the necessary materials:

  • A cup filled with water (to measure the ratio needed for hardener and resin).

  • Two empty cups (for mixing and weighing the hardener and resin).

  • Spoons for mixing.

  • The mold to be used (bookmark mold in this case).

  • A scale for accurate measurement.

Step 02:Preparing the Mold:

  • We placed the mold on the scale and zeroed it.

  • We chose a bookmark mold for this process.

Step 03:Measuring the Mold’s Volume:

  • We poured water into the mold, filling the desired spaces.

  • Then, we measured the weight of the water on the scale 44.4 ml.

  • Afterward, we removed the water from the mold and dry it thoroughly with tissue paper to prepare it for resin usage.

Step 04:Measuring the Resin:

  • We placed the first empty cup on the scale, zeroed it, and poured 34.4 ml of resin into the cup.

Step 05:Measuring the Hardener:

We placed the second empty cup on the scale, zeroed it, and poured 34.4 ml of hardener into the cup.

Step 06:Mixing the Resin and Hardener:

  • We poured the resin (from the first cup) into the hardener (in the second cup).

  • mixed it thoroughly for one minute.

  • We Repeated the process by pouring the mixture back into the first cup and mixing again for one minute to ensure consistency.

Step 07:Coloring the Mixture:

  • We divided the mixed resin and hardener into two cups.

  • Then, we added colored powder (pink for the first batch) to one of the cups, little by little, mixing until the desired color is achieved.

Step 08:Pouring into the Mold:

  • We poured the clear resin mixture and the colored resin mixture into the mold as desired.

  • For the remaining clear resin, we added purple powder, mixed it thoroughly, and poured it into the mold.

  • Finally, we added gold foil to the poured resin for decorative purposes.

Step 09:Curing and Demolding:

  • We allowed the resin to cure and dry for 24 hours.

  • Once fully cured, we removed the resin items from the mold.
