2. Setup and Preparation

Proper preparation is crucial for successful mold creation. Follow these steps carefully:

2.1. Materials and Environment

• Ensure your workspace is clean, dry, and well-ventilated.
• Gather all necessary tools: mixing cups, stir sticks, scale for accurate measurement, and your original model.
• Wear appropriate personal protective equipment, such as gloves and eye protection.

2.2. Mixing Instructions

1. Prepare the Mold Box: Construct a mold box around your original model, ensuring it is sealed to prevent leaks.
2. Measure Components: The Alumilite Plat 25 uses a simple 1:1 mixing ratio by weight or volume. Carefully weigh or measure equal parts of Part A and Part B into a clean mixing container.
3. Mix Thoroughly: Stir the mixture thoroughly for at least 4 to 6 minutes. During mixing, scrape the sides and bottom of the container to ensure all material is fully incorporated. Incomplete mixing can lead to soft or uncured spots in the mold.
4. Degassing (Recommended): For best results and to eliminate air bubbles, degas the mixed silicone in a vacuum chamber.

3. Operation: Pouring and Curing

Once the silicone is thoroughly mixed and degassed, it is ready for pouring.

3.1. Pouring the Silicone

• Slowly pour the mixed Plat 25 into the lowest part of your mold box.
• Avoid pouring directly over the original model to minimize air entrapment. Allow the silicone to flow naturally around the model.
• The working time for Plat 25 is approximately 35 minutes.

3.2. Curing and Demolding

• Allow the mold to cure at room temperature.
• Plat 25 is typically ready to demold after 24 hours.
• The mold will achieve full cure in 7 days, reaching its optimal strength and flexibility.

4. Care and Maintenance

To prolong the life of your Alumilite Plat 25 silicone molds:

• Clean molds thoroughly after each use with mild soap and water.
• Avoid using abrasive cleaners or sharp objects that could damage the mold surface.
• Store molds flat in a cool, dry place away from direct sunlight and extreme temperatures.

5. Troubleshooting Common Issues

If you encounter issues during the mold-making process, consider the following:

5.1. Soft or Uncured Spots

• Cause: Incomplete mixing of Part A and Part B.
• Solution: Ensure thorough mixing for the recommended 4-6 minutes, scraping the sides and bottom of the container.
• Cause: Incorrect mixing ratio.
• Solution: Always measure equal parts by weight or volume accurately.
• Cause: Contamination from sulfur-based clays, latex, or other platinum cure inhibitors.
• Solution: Use only sulfur-free modeling clays and ensure all surfaces and tools are clean and free from contaminants.

5.2. Bubbles in the Mold

• Cause: Air introduced during mixing or pouring.
• Solution: Mix slowly and deliberately. Pour the silicone from a high point in a thin stream into the lowest part of the mold box.
• Cause: Not degassing the silicone.
• Solution: Use a vacuum chamber to degas the mixed silicone for best results.
