Create Anything with Thermoforming
Thermoforming is a manufacturing process where a plastic sheet is heated to a pliable forming temperature, formed to a specific shape in a mold, and trimmed to create a usable product. Hunter Plastics offers a variety of thermoforming machines.
Sheet Fed Thermoforming Equipment: Sheet-fed thermoforming is when a single sheet of plastic is loaded into the machine at a time. The Process includes:
- Operator loading
- Heating of the oven
- vacuum seal
- Cooling and Unloading
We also have machines that can accomplish all of these steps simultaneously such as a shuttle or a rotary machine. However, these machines can be expensive to install, so you want to make sure that you have a large production rate to compensate for the costs to install the machinery.
These sheet-fed thermoforming machines come in multiple different options as well other than just mold size. Some of the different styles of these machines are: Ceramic, infared, gas, and calrod.
Roll-fed thermoforming machines: Roll-fed machines traditionally have a greater output capacity than the sheet-fed style. This is because the machines are automated and can perform multiple tasks simultaneously, thus producing more products. These machines are usually used in the production of food packaging, and blister, clamshell packaging industries. The plastic sheet that is fed into the thermoformer is heated and formed then it is measured to be trimmed. The trimming can be done in the thermoformer machine or is can be moved to a different machine called a trim press. The trimming separates the final product from the plastic scrap and then that excess plastic is recycled to make other products.
Inline thermoforming can also have a variety of options like servo plug drive, shallow or deep draw heights, the width of forming, but most thermoforming machinery is used in the market of servo-driven machines.
