Ice Cream Packaging - Injection Moulding VS Blow Molding
Injection moulding (injection molding in the USA) is a manufacturing process for producing parts by injecting material into a mould. Material for the part is fed into a heated barrel, mixed, an-d forced into a mould cavity, where it cools an-d hardens to the configuration of the cavity.
Blow molding ( BrE moulding ) is a manufacturing process by which hollow plastic parts are formed. In general, there are three main types of blow molding: extrusion blow molding, injection blow molding, an-d injection stretch blow molding. The blow molding process begins with melting down the plastic an-d forming it into a parison or in the case of injection an-d injection stretch blow moulding (ISB) a preform. The parison is a tube-like piece of plastic with a hole in one end through which compressed air can pass. The parison is then clamped into a mold an-d air is blown into it. The air pressure then pushes the plastic out to match the mold. Once the plastic has cooled an-d hardened the mold opens up an-d the part is ejected.
There are some advantages an-d disadvantages to using injection moulding an-d blow molding.
Injection Molded Cases
Advantages
Injection molding allows plastic-molding companies to be able to produce more complex products in different shapes an-d designs. Injection Molding is suitable for mass production. It means that the injection molding process is more ideal for a high volume of cases needed. With the injection molding process molding companies will be able to mass produce parts an-d create the product at the same time. Injection molding creates a high production out put while having a low labor cost an-d it is an easy process to repeat.
Disadvantages:
Injection molding involves more effort on creating the mold. The main disadvantage to injection molding is the cost. The number of cavities incorporated into a mould will directly correlate in moulding costs. There are also some limitations to what types of designs can be made with this process.
Blow Molding Cases
Advantages:
The process that blow mold manufacturers use is not time-consuming or lengthy. The process is affordable an-d produces long-lasting cases that are lightweight an-d available to use in many different situations. We can blow mold products in a variety of volumes, including low an-d high. The blow molded process gives product designers a good amount of flexibility over the manufacturing of the products. Blow molded products can produce a high volume of products in a quick turnaround time. Having the ability to produce a high volume gives product producers the ability to create a lot of cases in a short amount of time, when needed.
Disadvantages:
Blow molding is limited to hollow forms, such as plastic containers an-d bottles, as air pressure is an integral component of the process. Wall thickness is also hard to control, as the larger the product being built gets, the thinner the polymer has to be stretched.
