For many years, plastic has been a popular material to use for various products and goods. The methods to produce plastic might not be something that many people think about. However, there are many ways in which this occurs. They are effective because plastic is malleable and budget-friendly. Plastic is also a highly useful material with extreme durability. Plastics fabrication is a fascinating process to understand and take part in.
Types of Plastics
Not all plastics are the same. They come in two categories: thermosetting plastics and thermoplastics. The degree to which the plastics can withstand certain temperatures and their malleability determine this category. When you can mold plastic multiple times, it is thermoplastic.
With these, a plastic fabrication company will continually remold the material by softening and melting it. This allows the desired reshaping to occur. A thermosetting plastic does not have these abilities. Within these two categories are the following varieties of plastics.
- Polyethylene Terephthalate
- High-density Polyethylene
- Polyvinyl Chloride
- Polypropylene
- Polystyrene
- Miscellaneous
Methods That Plastic Manufacturing Companies Use
One of the most common ways to produce plastics is through welding. This melts more than one plastic together to form a single piece. Plastic welding uses pressing, heating, and cooling to complete this process.
Another option for plastics fabrication is compounding. This tactic blends multiple plastics with additives. A technician then forms this combination into various pieces. This occurs via molds and dies. This method simplifies the ability to process various plastics. Common compounding plastics include base resins, blowing agents, and purge compounds.
Lamination is another type that companies may use. Here, the technician holds multiple layers together. This creates a barrier along the surface of another material. When a company uses this option, the product has better durability. It also has a pleasing look and less need for maintenance and upkeep. The technique does take a lot longer than others, however you will see it frequently in the production of film, resin, and lamination.
Plastic molding has been common for decades and still has merit today. A technician heats the plastic, melting it and then the melted plastic goes into a mold to harden. There is also injection molding, which a plastic fabrication company may use to make car parts. It includes the steps of clamping, injection, dwelling, cooling, and mold opening.
Other Options
Plastic fabrication is versatile and can suit the needs of many users. Other popular methods of fabricating plastics include compressed molding, blow molding, rotational molding, thermoforming, extrusion, die-cutting, and pultrusion.
Methods You Can Count On
If you work in an environment that fabricates plastic, you will likely use one of these techniques. It is good to understand these plastics fabrication options. Call the team at Johnston Industrial Plastics to learn more.
