These factories excel in delivering custom solutions for various industries, leveraging advanced equipment and expertise.

Что такое вакуумная формовка?

Vacuum forming, a type of thermoforming, heats a thermoplastic sheet until pliable, then uses a vacuum to pull it over a mold, cooling it to form a solid shape. It’s valued for its simplicity and cost-effectiveness.

Vacuum forming shapes heated термопластичные листы⁴ over molds using vacuum pressure, ideal for producing large, lightweight parts with moderate detail.

• Core Principles: Heating softens the plastic, vacuum pressure forms it, and cooling solidifies the shape.

• Классификация:

  • By mold type⁵: Male (positive) or female (negative).
  • By sheet thickness: Thin-gauge (<0.06") or thick-gauge (>0.12").

Какие этапы включает в себя процесс вакуумной формовки?

Process Breakdown

The vacuum forming process transforms plastic sheets into finished parts through these steps:

Vacuum forming involves heating, shaping, and cooling plastic sheets over molds, producing parts for packaging, automotive, and medical use.

1. Clamping: Secure the plastic sheet in a frame.

2. Отопление: Warm the sheet to its forming temperature (e.g., 275°F for ABS).

3. Формирование: Apply vacuum pressure to shape the sheet over a mold.

4. Охлаждение: Cool the part to set its shape.

5. Обрезка: Remove excess material.

6. Отделка: Add secondary operations like painting or drilling.

What are the Key Factors in Vacuum Forming?

Technical Insights

Several factors influence vacuum forming outcomes:

Vacuum forming depends on temperature, vacuum pressure, and mold design, affecting part quality and efficiency.

• Температура формования: Must match the material (e.g., 250°F–350°F).

• Вакуумное давление: Ensures tight mold contact.

• Дизайн пресс-формы: Draft angles (min. 3°) and vent holes are critical.
