Quick answer: A vacuum formed tray is a carrier tray made by heating a PET or PS plastic sheet and vacuum-forming it against a mold, used to precisely position and protect electronic components, IC chips and industrial products. Choose PET when you need clarity and recyclability; choose PS when you need anti-static properties and rigid support.
01Vacuum Forming: A Key Process for Electronics & Industrial Packaging
Vacuum forming (thermoforming) heats a plastic sheet until pliable, then uses vacuum suction to draw it tightly against a mold surface, cooling it into shape. With short development cycles, high cost-efficiency and great design flexibility, it is indispensable for electronics and industrial packaging.
02Material of Choice: PET vs PS Sheet
Choosing the right material is the first step in protection. Guann-Ming mainly uses PET and PS sheets — here is how they compare:
| Criteria | PET sheet | PS sheet |
|---|---|---|
| Key strengths | Clarity, high toughness, chemical resistance | Rigidity, good forming flow |
| Anti-static / conductive | Harder to modify | Easily modified |
| Recyclability & grade | Recyclable, anti-fog, food/electronic grade | Precision electronic support |
| Best for | Display-grade, sustainability-focused packaging | Rigid protection for precision components |
Rule of thumb: need clarity or recyclability → PET; need anti-static or rigid support → PS. Confirm the final choice with our engineering contact based on your component and environment.
03High-Protection Electronic Trays & Support Trays
Electronics demand extremely careful component storage — a tiny impact or static event can scrap an entire batch. Vacuum-formed trays are built for exactly this.
- Custom pocket design: molded precisely to the product shape, giving each component its own fixed cavity to prevent friction.
- Stepped stacking design: empty trays nest tightly to save storage; loaded trays stack securely to prevent crushing.
04Our Advantages & Applications
Guann-Ming offers integrated capability from sheet selection and precision mold design to vacuum forming, delivering low-cost, high-efficiency packaging fast.
- Main applications: electronic precision-component trays, semiconductor wafer/chip box liners, optical lens protection trays, and industrial / consumer product liner trays.
