How many types of plastic moulding are there?
Roughly there are 5 types of the plastic moulding, they are extrusion moulding, compression moulding, blow moulding, injection moulding and rotational moulding.
Base on different shape and design of a parts, you can decide which one will be the most effective for you to use.
1. Extrusion Moulding
2. Compression Moulding
3. Blow Moulding
4. Injection Moulding
5. Rotational Moulding
1. Extrusion Moulding: This process is used to create long, continuous shapes such as pipes, tubing, and sheets. It involves forcing molten plastic through a die to create the desired shape.
2. Compression Moulding: This method is suitable for producing large, intricate parts with high strength and durability. It involves placing a heated plastic material into a mold and compressing it with a hydraulic press to form the desired shape.
3. Blow Moulding: This process is commonly used to produce hollow objects such as bottles and containers. It involves blowing air into a heated plastic tube to expand it into the shape of the mold.
4. Injection Moulding: This is one of the most widely used plastic moulding processes for producing a variety of complex parts with high precision. It involves injecting molten plastic into a mold under high pressure to form the final product.
5. Rotational Moulding: This method is ideal for producing large, hollow parts such as tanks, containers, and playground equipment. It involves rotating a mold with the plastic material inside a heated oven to evenly coat the interior of the mold and form the desired shape.
