真空成形に使用される一般的な材料とは？

Vacuum forming relies on thermoplastic materials that can be heated, shaped, and cooled to form durable products. Each material has unique properties suited for specific applications.

Common vacuum forming materials include ヒップス⁷, ABS⁸, PET⁹, PVC, and PP, chosen for their formability, durability, and cost-effectiveness in packaging, automotive, and consumer goods.

素材タイプ	Recommended Max Thickness	備考
ヒップス	3 - 4 mm	コストパフォーマンスが高く、成形が容易
ABS	Up to 6 mm	Higher impact resistance
PET	1 - 2 mm	Clear, rigid, food-safe
PVC	2 - 3 mm	Flexible, cost-effective
PP	2 - 4 mm	Recyclable, good for food contact

ハイインパクトポリスチレン（HIPS）

HIPS is a cost-effective, easy-to-form material ideal for low-impact products like packaging trays and disposable items. Its affordability and versatility make it a popular choice in the packaging industry.

アクリロニトリル・ブタジエン・スチレン（ABS）

ABS offers higher impact resistance and durability, making it suitable for automotive parts, consumer goods, and other applications requiring strength and longevity.

ポリエチレンテレフタレート（PET）

PET is clear, rigid, and commonly used for food packaging and blister packs due to its excellent barrier properties and recyclability.

ポリ塩化ビニル（PVC）

PVC is flexible and cost-effective, often used for blister packaging. However, environmental concerns due to its chlorine content have led to a shift toward more sustainable materials.

ポリプロピレン（PP）

PP is recyclable and suitable for food contact, making it ideal for food trays and containers. It offers good chemical resistance but may have lower clarity compared to PET.

真空成形プロセスのステップとは？

The vacuum forming process is a straightforward yet precise method for shaping plastic sheets into functional products. Each step must be carefully controlled to ensure high-quality results.

The vacuum forming process involves clamping, heating, forming, cooling, trimming, and finishing plastic sheets to create shaped products for various industries.

Clamping

The plastic sheet is secured in a frame to prevent movement during heating and forming. The frame must be robust enough to handle the sheet’s thickness, typically ranging from 1 to 10 mm.

暖房

The sheet is heated using infrared or radiant heaters to a pliable temperature, typically between 120°C and 180°C, depending on the material. Proper temperature control is crucial to avoid overheating or underheating.

成形

The heated sheet is stretched over a mold, and vacuum pressure (typically 28-30 inches of mercury) is applied to draw the plastic tightly against the mold, ensuring accurate shaping.

冷却

The formed part is cooled using fans or ambient air to solidify the plastic and retain its shape. Cooling time varies based on material thickness and mold design.

トリミング

Excess material (flash) is removed using cutting tools or CNC machines to achieve the final part dimensions. Precision in trimming is essential for part quality.

仕上げ

Additional operations like printing, assembly, or secondary machining may be applied to meet specific product requirements, such as branding or functionality.

真空成形プロセスにおける重要な要素とは？

Several factors influence the quality and efficiency of the vacuum forming process. Understanding these can help optimize production and ensure consistent results.

Key factors in vacuum forming include temperature control, vacuum pressure, and material thickness, which directly affect the part’s quality, detail, and strength.

温度管理

Proper heating ensures the plastic is pliable enough to form without overheating, which can cause material degradation or poor surface finish. Each material has an optimal forming temperature range.

真空圧

Sufficient vacuum pressure is necessary to draw the plastic tightly against the mold. Inadequate pressure can lead to incomplete forming, while excessive pressure may cause defects like webbing or thinning.

材料の厚さ

Thicker sheets require longer heating times and may limit the complexity of shapes that can be formed. Thinner sheets are more suitable for intricate details but may lack strength for certain applications.

真空成形の用途は？

Vacuum forming is used across a wide range of industries due to its versatility and cost-effectiveness. It is particularly valuable for producing large, lightweight parts with relatively low tooling costs.

Vacuum forming is applied in packaging, automotive, consumer goods, signage, and medical industries for creating lightweight, durable, and cost-effective products.

包装業界

Vacuum forming is ideal for producing blister packs, clamshells, and trays used in food, electronics, and pharmaceutical packaging. It offers excellent product visibility and protection.

Automotive Sector

The process is used to create interior components like dashboards, door panels, and trim parts, providing a cost-effective solution for large, complex shapes.

消費財

Vacuum forming is used for appliance housings, furniture components, and toys, offering lightweight and customizable options for manufacturers.

看板とディスプレイ

The process is applied in creating dimensional signs and retail displays, leveraging its ability to produce aesthetically pleasing and functional designs.

Medical Applications

Vacuum forming creates trays for medical devices and packaging for pharmaceuticals, ensuring hygiene, tamper-resistance, and ease of use.

真空成形と射出成形の違いは？

Understanding the differences between vacuum forming and other manufacturing processes like injection molding can help businesses choose the right method for their needs.

Vacuum forming offers lower tooling costs and faster setup times compared to injection molding, making it ideal for large parts and prototyping, but it lacks the precision and strength of injection-molded parts.

Tooling Costs and Setup Times

Vacuum forming molds are simpler and cheaper to produce than injection molding tools, making it more cost-effective for small to medium production runs and prototyping.

Part Complexity and Precision

Injection molding allows for higher precision and more complex geometries, while vacuum forming is better suited for simpler, larger parts.

素材の選択

Injection molding can use a wider range of materials, including thermosets, while vacuum forming is limited to thermoplastics.

生産量

Injection molding is more efficient for high-volume production due to faster cycle times and automation, whereas vacuum forming is better for lower volumes or larger parts.

結論

Plastic vacuum forming is a versatile and cost-effective manufacturing process widely used in Indonesia for producing a variety of products across industries. Factories like PT. FLN, PT. Vacpack Indonesia, and PT. Surya Indo Plastic are leading the way in providing high-quality vacuum-formed products, from packaging solutions to automotive components. By understanding the materials, process steps, key factors, and applications of vacuum forming, businesses can leverage this technology to meet their manufacturing needs efficiently.
