Nine Techniques To Consider For Your Plastic Processing Job
Posted on: 9 February 2023
Choosing the best techniques for the task at hand is essential when you need to have plastic processing work done as part of your recycling efforts. Plastic processing involves many technique options to choose from to get the job done.
You should familiarize yourself with plastic processing techniques to plan out your job to achieve maximum productivity and efficiency. The following are nine techniques to consider for your plastic processing job.
Injection molding
Injection molding is one of the most popular and versatile plastic processing techniques. This technique involves injecting heated plastic material into a replaceable mold. Injection molding frequently offers multi-impression capabilities to maximize efficiency.
Rotational molding
Rotational molding is typically the method of choice when plastic processing must produce large-scale plastic objects like water tanks. With rotational molding, a mold is heated and then filled with a charge weight of material to form the plastic form that is desired.
Coatings
In plastic processing, coating is a process that can involve roll, blade, or curtain coating. The process involves coating a liquid material over a web structure.
Blow molding
Blow molding processes are classified as either extrusion or injection blow molding. Blow molding is typically the process of choice for producing bottles or similar hollow plastic items.
Extrusion
Extrusion is another very common technique when it comes to plastic processing. Extrusion is a technique that is frequently chosen for high-volume production.
The extrusion technique involves using a polymer that is formed into granulates and contains certain additives. This polymer is fed into a hopper and feed throat assembly to create the desired forms.
Thermoforming
Through thermoforming, plastics are processed while they are exposed to enough heat to bring the materials to a rubbery state. This technique is often used when small, thin plastic parts are produced.
Spinning
Spinning is a process that is chosen when plastic must be formed into fibers. In this process, a spinneret is used to form a melted polymer. Fibers are produced as the melted polymer material goes through the spinneret.
Compression molding
Compression molding forms plastic parts through the use of a mold that includes two plates with a cavity toward the bottom. The mold is heated through electricity or steam according to the particular temperature requirements of the project. The cavity is filled with the plastic material after the plates are heated.
Calendaring
Calendaring is a plastic processing technique that is typically used to produce sheet forms. Calendaring involves using a machine that is composed of two rollers that rotate together. Sheet thickness is determined by how closely the rollers are placed together. Plastic is forced through the rollers to create sheet forms.
