Plastic is a very popular material that is used in almost all the industries. It is a flexible raw material that can be molded into any shape and form. A whole of articles and components are manufactured using plastic. There are different types of plastic raw materials that are used in combination to achieve certain industry specifications. Plastic is used for making kitchen appliances, articles of use, accessories, stationery items, bags, etc. Several manufacturing companies and industries such as electronics, automotive companies, food manufacturing industries and pharmaceutical companies use vacuum formed plastics packaging products and components that comprise their main product.
Plastic Thermoforming Process
In the plastic thermoforming process, heat is used on plastic sheets till it is pliable enough to be formed into a specific shape using a mold and then trimmed into shape to create a usable product. For mass vacuum forming plastic production, the manufacturing process is completely mechanized. Thin-gauge thermoforming is popularly used for manufacturing containers, disposable trays, cups, lids, clamshell packaging, blister packaging and various other products for industries that include medical, food and retail industries. Thick-gauge thermoforming is used for producing aircraft instrument panels, vehicle door panels, truck liners, refrigeration liners, pallets, etc.
Types of Plastics That Can Be Used For Vacuum Molding
There are different types of raw materials that can be used to produce a wide range of vacuum formed plastics products. Some of these include Polyethylene Terephthalate for producing food and non-food packing products, remanufactured polyethylene terephthalate for producing food and utility packaging, Polylactic acid for producing packaging for food products made from corn derivates, Polypropylene for producing bakery containers, domes and clamshells, Polyvinyl Chloride for producing blister packaging and other packaging varieties that require rigidity and strength. PVC is another variety of pharmaceutical grade which is used worldwide for pills blister packaging.
Advantages of Vacuum Forming Plastic
There are several advantages of vacuum forming compared to traditional methods. This form of manufacturing process offers excellent cost savings on smaller production runs as prototypes are created using wood molds that offer quick and inexpensive design adjustments. Production parts can be created from relatively inexpensive epoxy and aluminum molds. This process offers wide range of colors and characteristics on finished products. Thermoforming of plastic produces thin-walled products precisely and cost effectively. Thousands of product types can be created such as paint trays, instrument panels, packaging products, blister packs, bakery domes, plastic trays, and countless other products can be manufactured for personal and industry uses.
