What kind of carrier molds are used?

Carrier molds are used in various manufacturing processes, particularly in the production of composite materials, plastics, and other items that require a specific shape or structure. The types of carrier molds can vary based on the application and the materials being used. Here are some common types of carrier molds:

1. **Injection Molds**: Used in the injection molding process to shape thermoplastics and thermosetting plastics. These molds are designed to withstand high pressure and temperature.

2. **Blow Molds**: Used for creating hollow plastic parts, such as bottles and containers. The process involves inflating a heated plastic tube within a mold.

3. **Compression Molds**: Used in compression molding, where material is placed in a heated mold cavity and then compressed to shape the final product. This is often used for rubber and thermosetting plastics.

4. **Rotational Molds**: Used for creating large hollow items by rotating a mold around multiple axes. This technique is often used for items like tanks and playground equipment.

5. **Vacuum Molds**: Used in vacuum forming processes, where a sheet of plastic is heated and then formed over a mold using vacuum pressure. This is common for creating packaging and trays.

6. **Die Cast Molds**: Used in die casting processes, typically for metals, where molten metal is injected into a mold under high pressure.

7. **3D Printed Molds**: Increasingly being used for rapid prototyping and low-volume production, these molds can be created using additive manufacturing techniques.

8. **Ceramic Molds**: Used in processes like slip casting and for creating ceramic items, where a liquid clay mixture is poured into a mold to form a solid object.

The choice of carrier mold depends on the specific requirements of the manufacturing process, including the material properties, production volume, and desired product characteristics.
