 Types of vacuum molding products
|
 |
: is like snapback forming except that the thermoplastic sheet |
| |
is stretched to the base of the mold. In both cases, the use of air to stretch the |
| |
material prior to vacuum sealing and application to the mold permits the material to |
| |
thin uniformly. |
|
|
Plug forming: is a thermoforming procedure that |
| |
uses a plug or male mold to press the heated |
| |
thermoplastic material into the female mold prior
|
| |
to the application of a vacuum. This method helps |
| |
uniformly distribute the sheet. |
|
: is a thermoforming procedure |
| |
that involves applying pressure to the top of the |
| |
plastic sheeting while the vacuum force pulls downward. Pressure forming is done |
| |
through air pressure or mechanical means, and provides greater precision because the |
| |
plastic is able to attain a greater definition of shape in the mold. |
|
: is the process of pre-stretching the sheet material with a |
| |
vacuum box.A partial vacuum is then applied to the box, just enough for the necessary |
| |
stretching, and the mold is pushed into the material where the box is vented to |
|
atmospheric pressure that draws on a vacuum. |
| |
Straight vacuum forming: is vacuum thermoforming using only female molds that |
| |
produce a material distribution that is the opposite of the results obtained from male |
| |
molds. |
