(*Disclaimer: The 550°C claim for ThermaCAST™ Resin is based on optimal conditions and proper mould design. The resin’s performance at high temperatures depends on several factors, including the mould’s wall thickness, design, and the volume of metal being poured relative to the mould’s size. Exceeding recommended casting parameters may lead to mould degradation or failure. Always ensure your mould is appropriately designed and tested for your casting requirements.)

Compatible Metal Information

Here are some metals that can be cast at temperatures under 500°C:

1. Pewter: is a low-melting-point alloy, typically consisting of tin mixed with small amounts of other metals like copper, antimony, bismuth, or lead. It melts around 170-230°C, making it ideal for low-temperature casting.
2. Tin: has a melting point of around 232°C. It’s often used in casting for applications like figurines, medals, and small parts.
3. Lead: melts at about 327°C. It’s commonly used for casting fishing weights, bullets, and other applications where its density is advantageous.
4. Zinc: Its melting point is approximately 419°C, but it can be alloyed with other metals to lower it. Zinc alloys are frequently used in die casting for small components.
5. Bismuth: Melts at about 271°C. It is often used in low-melting-point alloys for safety devices like fire sprinkler systems and metalworking applications.

6. Cadmium: Although not commonly used due to toxicity concerns, cadmium melts at around 321°C. It’s sometimes found in certain low-melting-point alloys.
7. Indium: Indium has a melting point of 156°C. It’s used in some specialty low-melting-point alloys and for applications requiring soft, malleable metals.
8. Field’s Metal: This is a fusible alloy consisting of bismuth, indium, and tin, with a melting point of approximately 62°C. It’s often used in demonstrations and for creating fusible plugs in safety devices.
9. Wood’s Metal: Another fusible alloy with a melting point around 70°C, composed of bismuth, lead, tin, and cadmium. It’s used in similar applications to Field’s Metal.
10. Rose’s Metal: Melting at around 98°C, this alloy of bismuth, lead, and tin is used for similar applications where low melting points are advantageous.

Metal Melting and Pouring Temperatures Guide

The table below shows temperature ranges for low-melting-point metals ideal for ThermaCAST™ Resin moulds. Optimal casting temperatures are typically 50–100°C (122–212°F) above the melting point, depending on mould size, detail, and shape. These metals are commonly used for jewellery, custom components, and small-scale manufacturing.

Metal Melting Temperature (°C) Melting Temperature (°F) Optimal Pouring Temperature (°C) Optimal Pouring Temperature (°F)
Pewter 170–230 338–446 280–300 536–572
Tin 232 450 280–300 536–572
Bismuth 271 520 300–320 572–608
Lead-Free Solder 217–227 423–441 250–270 482–518
White Metal 200–250 392–482 280–300 536–572
Zinc 420 788 480–510 896–950
Zinc Alloy (ZA12) 432 810 480–500 896–932
Zinc Alloy (ZA 3/5) 386 727 430–450 806–842
Indium Alloy 156–200 313–392 220–240 428–464

The melting temperature is the minimum temperature at which metal transitions from a solid to a liquid. The optimal pouring temperature is slightly higher to ensure smooth flow and proper filling of mould details. Casting at the right temperature improves flow, minimises defects like air pockets and shrinkage, and protects the mould from overheating. Choose a metal that suits your project, use a thermocouple for accurate monitoring, and preheat and dry the mould to prevent steam-related issues.

ThermaCAST™ | Final Tips

Keep Moulds Cool Between Casts

Allow your mould to cool completely before reusing to prevent warping or cracking, especially for intricate designs.

Monitor Metal Temperatures

Always use a thermocouple to ensure the molten metal is at the optimal pouring temperature, as furnace gauges can be inaccurate.

Use High-Quality Release Agents

Apply 100% pure talc or fine graphite powder to ensure a clean part release. Avoid cornstarch-based products, as they can burn.

Plan for Safety First

Always work in a well-ventilated area, wear proper PPE (heat-resistant gloves, face shields, and aprons), and keep a powder-based fire extinguisher nearby.

Frequently Asked Questions (FAQs)

ThermaCAST™ is compatible with a variety of low-melting-point metal Alloys (under 550°C), including:

  • Pewter
  • Zinc and Zinc Alloys (such as ZA2 / 3 / 12)
  • White Metals (e.g., Tin Alloys, Bismuth Alloys)
  • Bismuth Alloys
  • Lead-Free Solder Alloys
  • Indium Alloys

NB: Always ensure the materials pouring temperature does not exceed 550°C.

While ThermaCAST™ is durable and suitable for repeated use, high-volume production may require multiple moulds or considering other materials designed for mass manufacturing. ThermaCAST™ is ideal for small to medium-scale projects, prototyping, and bespoke applications.

After post-curing, allow the mould to air dry thoroughly. For added assurance, use a dehydrator or low-temperature oven (40-50°C) for at least 30 minutes, adjusting the time based on mould size. Ensure no moisture or cleaning residue remains by using compressed air or a hairdryer.

Possible reasons include:

  • Check the design of the mould: Ensure it has adequate draft angle and is free from any undercuts.
  • Insufficient Application of Release Powder: Ensure a light, even layer of talc or graphite powder.
  • Overly Tight Clamps: Prevent proper release by adjusting clamp tightness.
  • Mould Warping: Excessive heat can warp the mould, affecting release.
  • Inadequate Cooling: Allow sufficient cooling time before attempting to remove the part.

Yes, ThermaCAST™ moulds are designed for multiple uses. Proper maintenance, cleaning, and careful handling will extend the lifespan of your moulds. Reapply release powder before each use to ensure easy part release.

If your mould shows signs of warping or cracking:

  • Assess Usage: Ensure you are not exceeding the recommended temperature limits.
  • Wall Thickness: Verify that mould walls are sufficiently thick.
  • Cooling: Allow adequate cooling between pours to prevent thermal stress.
  • Storage: Store moulds properly to avoid deformation.

When used according to guidelines and with appropriate PPE, ThermaCAST™ is safe for handling. Always follow safety instructions to minimise exposure to uncured resin and molten metals.

Dispose of excess resin and cleaning solvents in accordance with local regulations. Do not pour resin down drains or dispose of it in regular trash. Refer to your local waste management guidelines for proper disposal methods.

Search on Amazon or eBay for “electric metal melting furnace”. For Safety Gear, check your local hardware store in the welding section for gloves, face shields, and aprons.
