Plastic has widespread use as it is durable, flexible and lightweight. Plastics can be easily moulded or pressed to make a product of any shape and It is inexpensive to produce plastic products.
The two main technologies used to produce plastic products are Injection moulding and blow moulding. plastic manufacturing company in UAE design products and use advanced manufacturing and CAD-CAM technologies.
Different types of technologies
The two types of technologies used to make plastic products are:
Injection moulding
This technology is used by plastic manufacturers to make products like spacers, shims, custom moulded products, insulation accessories, aluminium facade accessories, steel fabrication accessories, medical accessories, aluminium cabinet corners and rolling shutter accessories.
In this technology, the molten material is injected into a mould. The material is first added in a heated barrel, mixed and injected into the mould cavity where it is cooled. It hardens and takes the shape of the cavity. The products to be moulded have to be designed carefully to facilitate the moulding process. A ram is used to force the molten plastic into the mould cavity.

The properties of plastics like the ability to soften and flow when heated make them highly suitable for this type of manufacturing process. There are single-cavity and multiple-cavity moulds used.
Blow moulding
This technology is used to make hollow products like jerry cans with sturdy handles. These cans can be used to store liquids, oils, chemicals and more. Such jars are used in the industries like lubricants, edible oil and more.
There are three types of blow moulding: Extrusion blow moulding, Injection blow moulding and Injection stretch blow moulding.
In this process, the plastic is first heated and softened. A parison which is a tube-like piece of plastic is used to make the compressed air enter. The plastic is put into a mould and the air is blown into it. The air pressure inflates the plastic which takes the shape of the mould. It is then cooled and hardened and the product is removed.
Post-moulding processes
Once the products are manufactured they undergo a post-moulding process to get the final output The different post-moulding processes are:
Mould/Parts painting
In this process, the products can be pained as desired using spray painting, powder coating, silk screening, stamping and in-moulding painting.
Ultrasonic welding
This process is used to soften the material along the joint line. Welding sonotrode is used to generate vibrations above the audible range.
Screen printing
This process is used to print patterns, images, multiple colours, text and logos on plastic products.
Hot stamping and hot foiling
This is a printing method in which pre-died ink or foils are printed on the surface at high temperatures.
Chrome plating
In this process, chrome is electroplated on plastic products.
