Vacuum Form Trays

Vacuum forming is a simplified version of thermoforming, whereby a sheet of plastic is heated to a forming temperature, stretched onto a single-surface mold, and forced against the mold by a vacuum is formed into permanent objects such as turnpike signs and protective covers.

The following are the material types:

  • HDPE

  • ABS

  • HIPS

  • PET

Thermoform Trays

Coralpack knows how important it is for you to deliver new products as promised and ahead of the competition. And when prototypes change at the last minute, it can be especially challenging to meet deadlines. Now our new Trays in Days program takes the worry out of getting custom trays produced in time for your prototype components, connectors and other small parts. With Trays in Days, we can produce one dozen, custom thermoformed trays for you to evaluate in just three days.

Tray Design

Give us the part geometry and we'll design the tray. Because we use Solid Works and Pro/E CAD software, we can handle almost any file type you give us. And your sample trays will be completed three days after approval of your tray design.

Tray Material

We keep all common thermoforming-grade materials in stock. These include: PVC, PETG, PET, HIPS, etc. ln addition, we can provide ESD-rated materials, both topical and intrinsic. Less common materials can be obtained, although this can delay delivery. Material thickness must be between 0.015" and 0.045".

Tray Format

Coralpack will build your tray according to the most recent thermoform tray standard: EIA-948 or EIA-960. We also will build trays according to any other layout you suggest, as long as the tray is no larger than 14" x 14" x 1.5".

Mold Specifications

We will use either a male or a female configuration, depending on the requirements and geometry of the tray. A plug assist will be provided if required. Since aluminum is used to make all molds, you will benefit from getting production-quality samples. An additional advantage of aluminum is that the mold can eventually be used for short- to medium-run production at Coralpack with no additional tooling charge.
