Injection Moulding Product for
Confectionery & Food Packaging
Thermoforming is a manufacturing process for thermoplastic sheet or film. The sheet or film is heated between infrared, natural gas, or other heaters to its forming temperature. Then it is stretched over or into a temperature-controlled, single-surface mold. Cast or machined aluminum is the most common mold material, although epoxy and wood tooling are sometime used for low volume production. The sheet is held against the mold surface unit until cooled. The formed part is then trimmed from the sheet. The trimmed material is usually reground, mixed with virgin plastic, and reprocessed into usable sheet [1]. There are several categories of thermoforming, including vacuum forming, pressure forming, twin-sheet forming, drape forming, free blowing, and simple sheet bending.

Thin and thick gauge thermoforming
There are two general thermoforming process categories. Sheet thickness less than 1.5 mm (0.060 inches) is usually delivered to the thermoforming press in rolls. Thin gauge roll fed thermoforming applications are dominated by rigid or semirigid disposable packaging. Sheet thickness greater than 3 mm (0.120 inches) is usually delivered to the forming press cut to final dimensions and stacked on pallets. Heavy or thick gauge, cut sheet thermoforming applications are primarily used as permanent structural components. There is a small but growing medium gauge market that forms sheet 1.5 mm to 3 mm in thickness.

Heavy gauge forming depended on convection oven heating of the sheet and draping of the sheet over male, female or paired molds. Aircraft windscreens and machine gun turret windows spurred the advance of heavy gauge forming technology during WWII. Heavy gauge parts are used as cosmetic surfaces on permanent structures such as automobiles, refrigerators, spas and shower enclosures, and electrical and electronic equipment.

In second process we have complete line like heat transfer printing, silkscreen printing, spray printing, and hot stamping in the end plastic product to improve the image and add value. Malaysia Plastic Thermoforming and Vacuum Pressure Forming Thermoforming and Vacuum Pressure Forming Product Range Thermoforming and vacuum forming equipment forms thermoplastic sheets or films over molds into finished shapes. First, the thermoplastic sheet or film is heated with electric, infrared, or natural gas heaters. Next, the thermoplastic material is stretched over a temperature-controlled, single-surface, aluminum mold. When the thermoplastic film is cooled, the formed part is trimmed from the sheet. Typically, the unused trim is reprocessed for subsequent use. There are several basic types of thermoforming and vacuum forming equipment. Pressure forming equipment applies a flow of positive air pressure between the mold’s surface and the thermoplastic sheet or film. Vacuum forming equipment applies negative air pressure between the mold and thermoplastic. Twin-sheet forming equipment combines two thermoplastic sheets into a uniform part. Drape forming equipment is used to produce parts with a gradual bend. Thermoforming and vacuum forming equipment that uses free blowing or simple-sheet bending techniques are also available. Selecting thermoforming and vacuum forming equipment requires an analysis of product specifications, features, and approvals. Thermoformer product specifications include: forming area, depth of draw, sheet width, material thickness range, machine dimensions, machine height, and air pressure. Air consumption, power consumption, main supply voltage, knife length, and clamping force are additional parameters to consider when selecting thermoforming machines. Typically, product output rates are measured in pieces per minute or pieces per hour. Some thermoformers feature robotic part handling, horizontal stacking, or multi-zone heaters. Others include a pneumatic or mechanical roll lift. A thermoforming machine with quick tool-change capabilities and a programmable logic controller (PLC) is a good choice for many applications. In terms of approvals, thermoforming and vacuum forming equipment often bears marks from organizations such as Underwriters Laboratories (UL) or the Canadian Standards Association (CSA).
