真空成形とは？

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 熱可塑性シート⁴ 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.

• 分類:

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

一般材料

Vacuum forming uses various 熱可塑性プラスチック⁶, each suited to specific applications:

Material choice impacts 成形温度⁷, durability, and aesthetics in vacuum forming.

真空成形プロセスのステップとは？

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

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

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

5. トリミング: Remove excess material.

6. 仕上げ: 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.

• 成形温度: Must match the material (e.g., 250°F–350°F).

• 真空圧: Ensures tight mold contact.

• 金型設計: Draft angles (min. 3°) and vent holes are critical.
