The Different Classification of Plastic Molding Machines

1. The Different Classification of Plastic Molding Machines

2. These days, plastics are highly used not only for our households but on making everything from automotive body parts to human body parts. But each of these plastic applications are requiring special manufacturing process which can mold the parts needed based on each specifications. For those who are planning to start their plastic manufacturing business, they should familiarize themselves with the types of plastic molding and their benefits.

3. 1. Compression Molding or Thermoforming This type of molding is ideal for larger objects like auto parts. Its name clearly implies how it works. A heated plastic material is placed in a heated mold and it will be compressed into shape. The plastic used in this molding mostly come in bulk but often comes in sheet. Aside from the statement above, this type of molding is very ideal for high-strength compounds such as thermosetting resins as well as for fiberglass making it a superior process for the automotive industry.

4. 2. Extrusion Molding This type is perfect for long hollow plastics such as pipes, straws and tubes. Unlike the other forms of molding, this type extrudes the melted plastic directly into a die. The die shape determines the final appearance or shape of the product.

5. 3. Injection Molding This is by far the most versatile of all injection molding techniques, because this is well suited for high quality and high volume part manufacturing. This is also the reason on why the majority of marketers engage with this business are aiming to have this machinery even it is already used plastic machinery. Although the mold making costs with this method can be a bit expensive, the cost per part is very economical making it very popular machinery with today’s manufacturing industry.

6. 4. Rotational Molding This type of molding is best for large and hollow one piece parts. This process has been using high temperatures and rotational environment to be able to coat the inside part of the mold and to form its parts. With the molds consistent rotation, it creates a centrifugal force which forms even walled products. This process is very economical and is cheaper compared to the other types of molding.

7. 5. Blow Molding This process if perfect for hollow items such as bottles, this process is following the basic steps mostly present in glass blowing. In this, a parison or a heated plastic mass is being inflated by the air. The air technically pushes the plastic against the mold to form the manufacturer’s desired shape. Once the plastic is cooled it will be ejected.
