– Blow Molding
Blow molding process is used to make hollow and seamless parts of thermoplastic polymers. It is best suited for basically hollow parts uniform wall thicknesses. Various dimensions (capacity) of plastic parts in the range of 4 liters for plastic bottles to 60 Liters for large storage drums are obtained by this process.
In this process the parison is ejected vertically until it is clamped inside the tool. Then air is injected through the blow-pin structure so that the product is molded along the cavity completely. The mold is then cooled down and the tool opened for the product to de-mold.
– Injection Molding
Injection molding process is a popular method in plastic industry. This process is the most commonly used manufacturing process for fabrication of plastic parts. A wide variety of products are manufactured by injection molding, which vary greatly in their size, complexity, and application.
This process is used to produce thin-walled plastic parts for a wide variety of applications, one of the most common being plastic housings. Plastic housing is a thin-walled enclosure, often requiring many ribs and bosses on the interior. These housings are used in a variety of products including household appliances, consumer electronics, power tools, and as automotive dashboards.
Other common thin-walled products include different types of open containers, such as buckets. Injection molding is also used to produce several everyday items such as toothbrushes or small plastic toys. Many medical devices, including valves and syringes, are manufactured using injection molding as well.
