The Process Of Making Thermoformed Plastic Packaging
The primary duty of custom thermoforming industries is to produce quality thermoformed plastic items. Examples of such products include; custom plastic radomes, thermoformed medical devices and thermoformed plastic enclosures. Generally, thermoforming industries deal with various thermoforming needs of their clients. Thermoformed plastic packaging products are also among these and can as well be made according to the specifications of a client.
Normally, the companies use in-door tools and machinery to meet the different requirements of thermoforming business. This may include temperature-controlled aluminum molds, fixtures and trim jigs that are custom designed to handle different projects. Virtually, all custom thermoforming companies use the same process of manufacturing thermoformed products.
The first procedure in thermoforming involves collecting all the needed sheets. There are a number of machines that can be used to thermoform different types of sheets. The latter are normally mounted on a clamp and then heated in an oven. The heating process takes a specified period of time before the sheet is removed for forming. Once heated, the hot sheet can be placed above or under the forming tool. This is done moving the tool up to the sheet.
In the next step, a seal is made around the sheet and a combination of vacuum and pressure is used to force the sheet to form the shape of the mold. After the sheet has been molded, it is held in place until the cooling process is over. The next step involves removing the sheet from the clamping and preparing it for trimming. The trimming can be done in a number of ways such as drilling, saw cutting, hand routing, and 3 or 5-axis machinery.
The finished parts of the sheets are then cleaned and packed in polybags once the thermoforming process is completed. There are also a number services that can also be offered by these companies. These may include pressure forming, vacuum forming, twin sheet thermoforming, heavy gauge thermoforming, and that of mold making. The vacuum forming, for instance, is majorly used for the production of medical devices.
Another version of the vacuum forming is pressure forming. It mainly adopts the traditional thermoforming techniques to bridge the appearance gap. Pressure forming is still regarded as an ancient mode of thermoforming and mainly used by the industries dealing with thin-gage plastic packaging. The twin sheet pressure forming on the other hand involves heating two sheets together and forming them at the same time. The sheets are normally preformed into respective molds and then pressed back together.
A pin is also pushed through one of the sheets and air is pushed through them for forming. This is carried out with the aid of heat to enable the sheets form a single unit. Usually, products made through this forming process resemble those made through blow molding or rotational molding.
The heavy gauge thermoforming is used to manufacture industrial, electronics and medical devices. It is majorly used for the manufacturing of sturdy rigid enclosures for various equipments like computers, radomes, electronic enclosures, medical devices, outdoor equipment, and exercise equipment. Heavy gauge thermoforming uses thick plastic sheets to manufacture products of different thickness. For thermoformed plastic packaging, there are a number of similar processes involved, but the most important thing is to go for those companies that can be able to customize products according to the needs of their clients.
