Great Choices for the Perfect Plastic Molding

The injection molding process can be used for bulk production of parts. The molten material is injected under pressure into a mold.

SHENZHEN, China - Sept. 12, 2019 - PRLog -- Just imagine we have to produce thousands of products like this one below (pen cap).  There are 1.5 billion liters of ice cream, there is also everything that is used for storage, transportation and the consumption of ice cream, which are jars, boxes and spoons, all made of plastic.

Examples of plastic molded parts
This is just an example of producing a product made of plastic, look at a car; most parts are made of plastic.we must have a shape and this is basically the foundation of injection molding. The process must be kept constant: maintaining the temperature, injection pressure and cooling efficiency time of the object. In addition to plastic injection, there are other molding processes, to name only those involving plastics, we have:
• Blow molding process
• Extrusion Process
• Rotational molding
• Vacuums Forming
• Injection Molding Process

Blow Molding
The Blow Molding Process is widely used for making jars, toys or other parts that are hollow inside. You will need the plastic injection molding manufacturers for such work.

Mold Closure
Airflow into the cavity causing the plastic to take the shape of the mold (throws the plastic against the mold walls)

Part opening and removal (process that can be automated).

Extrusion Molding
The process basically consists of forcing the passage of the heated and softened plastic through a matrix.

Plastic profile part is created by the extrusion process In addition, the extrusion process is also used for the formation of granules used in other processes (raw material).

Rotational Process
The process of plastic injection molding by rotational system or rotational molding is usually applied to large parts that do not have dimensionally and very rigidly hollow shape requirements. Or in cases of "rubber or similar" parts, the material is heated as the mold begins to rotate in various directions.

Vacuum Forming
This process consists of creating parts by suctioning a temperature-softened plastic sheet into a shape normally made of aluminum, through a vacuum created at the bottom.

Injection Molding Process
The injection molding process is (almost exclusively) the economically best choice for large scale production; however, the cost of the tool is often a significant investment, even relatively simple tools. Hence the importance of the Toolmaker, who is often responsible for designing, building and maintaining these production tools.

Plastic injection process
The equipment has several working options and can be of various types: ranging from simple machines to machines that inject more than one color in the same product, but the basics of an injector can be seen in the image below.
