Get Economic Plastic Products Using Various Plastic Molding TechniquesBy Expert Author: Johny Peter
General use of plastic:
The world without plastic is not possible because the use of plastic is huge. All the people in the world are using plastic in their day to day life. The applications of plastics products in our everyday life are countless some of them are mobile phones, clocks, toothbrushes, pen, bike etc. The one of the important use of plastic product is packaging purpose. All the cool drinks industries are using PET as a packaging material this shows the importance of the plastic material. The plastic products are available in many shapes. So the work of plastic mold manufacturers is to develop the quality product in the market.
Raw material and properties:
The raw material used in plastic molding is polymer resin. Polymer resin subjected to high pressure and temperature forms a hard polymer. The applied temperature varied based on the resin characteristics. After that the hard polymer is subjected in rollers to make a required shape. The quality plastic material must fulfill the following requirement they are free from chemical reaction with other materials and the mechanical property must be high. Based on the requirement the plastic mold manufactures treats the polymer resin. The material is used for outdoor usage then it must have the properties of high UV resistance and it should free from fire.
Plastic manufacturing process:
Plastic manufacturing involves several steps they are molding, this is the primary process for manufacturing process, other steps of manufacturing plastic is varied based on the requirement. The next step is machining, this step is used for make holes in the manufactured plastic. Third process is modification this step is used to shine the product and will give smooth surface, the final step is assembling all the parts to make a complete material.
Plastic molding technique:
The three major plastic molding technologiesare Extrusion, injection molding and combination of Extrusion and injection molding. In Extrusion the raw material are powdered the powdered plastic raw material is supplied to gyrating chamber this gyrating chamber is called as Extruder. The next step is shaping based on the requirement the plastic raw material is shaped. After shaping process the material is cooled with water to make a complete plastic product. In injection molding, techniques are same as the extrusion techniques but there is difference in the use of a hopper. The raw material is fed to melting chamber via hopper then the melted raw material is fed into the cold mold and then its applied high pressure the reason for giving high pressure is to clean the melted plastic and it also improve the quality of plastic material. Another technique is a combination of both extrusion and injection molding technique in this technique the blowing process is used either after extrusion process or injection molding process. These plastic molding technologies are used to manufacture quality plastic material.
