Thermosetting plastics are more suitable for extrusion moulding
Thermosetting plastics are actually not more suitable for extrusion moulding. Here's why:
- Extrusion Moulding Process: Extrusion moulding is a process used to create objects with a fixed cross-sectional profile. It involves forcing material through a die to create shapes such as rods, tubes, pipes, and ropes.
- Thermoplastics vs. Thermosetting Plastics: Thermoplastics are more commonly used in extrusion moulding as they can be melted and reshaped multiple times. They soften when heated and solidify when cooled. On the other hand, thermosetting plastics, once hardened by heat or chemical reaction, cannot be remelted or reshaped. This makes thermosetting plastics less suitable for extrusion moulding as the material cannot be easily reprocessed.
- Injection Die Moulding: Injection die moulding, on the other hand, is a process where exact amounts of material are delivered to fill a cylinder and then injected into a mould cavity. This process is generally limited to forming thermoplastic materials, which can be melted and cooled repeatedly without affecting their properties.
In conclusion, thermoplastics are more suitable for extrusion moulding due to their ability to be melted and reshaped multiple times, while thermosetting plastics are not ideal for this process as they cannot be remelted.
