What is the Vacuum Forming Process?

The vacuum forming process is straightforward yet highly effective, consisting of these key steps:

1. Pemilihan Bahan: Choose a thermoplastic sheet based on application requirements.

2. Pemanasan: Uniformly heat the sheet to its forming temperature.

3. Pembentukan: Drape the heated sheet over a mold and apply vacuum pressure.

4. Pendinginan: Cool the formed part to set its shape.

5. Pemangkasan: Remove excess material using cutting tools.

6. Penyelesaian: Perform secondary operations like printing or assembly.

Parameter Utama:

• Heating Time and Temperature: Must be controlled to prevent material degradation.

• Vacuum Level: Ensures proper adhesion to the mold.

• Waktu Pendinginan: Affects dimensional stability.

What Materials are Used in Vacuum Forming?

Vacuum forming utilizes a variety of thermoplastics, each chosen for specific properties:

• Polistiren (PS)⁷: Excellent clarity, ideal for display packaging.

• Polipropilena (PP)⁸: High heat resistance, suitable for food packaging.

• Polivinil Klorida (PVC)⁹: Rigid and chemical-resistant, used in blister packs.

• Akrilonitril Butadiena Stirena (ABS): Strong and impact-resistant, used in automotive parts.

• Polietilen Tereftalat (PET): Clear, recyclable, used in trays and containers.

Dampak Material:

• Suhu Pembentukan: Varies significantly (e.g., PS at ~120–150°C, PVC at ~150–180°C).

• Penyusutan: Materials like PP have higher shrinkage rates (~1–2%).

Apa Saja Aplikasi Pembentukan Vakum?

Vacuum forming serves a wide range of industries, including:

• Pengemasan: Blister packs, clamshells, trays.

• Otomotif: Interior trim, dashboards.

• Medis: Trays for surgical instruments.

• Konstruksi: Signage, architectural models.

• Dirgantara: Prototyping and interior components.
