What is Plastic Vacuum Forming?

Plastic vacuum forming is a simplified version of thermoforming where a plastic sheet is heated to a forming temperature, stretched onto a single-surface mold, and forced against the mold by a vacuum. This process is ideal for creating permanent objects such as packaging trays, automotive parts, and protective covers.

Vacuum forming uses heated plastic sheets⁴ and vacuum pressure to create custom shapes, offering a cost-effective solution for large, shallow parts with simple geometries.

Understanding the process and its applications is key to leveraging its benefits for your industry. Explore how different materials and molds affect the final product’s quality and performance.

What Materials Are Used in Plastic Vacuum Forming?

The choice of material is critical in vacuum forming, as it determines the part’s strength, flexibility, and suitability for specific applications.

Common materials for vacuum forming include polystyrene (PS), ABS, PVC, polyethylene (PE), polypropylene (PP), and polycarbonate (PC), each offering unique properties for different industries.

폴리스티렌(PS)

PS is an affordable material, commonly used in packaging due to its ease of forming. However, it is brittle and less durable than other options.

아크릴로니트릴 부타디엔 스티렌(ABS)

ABS offers a balance of strength and flexibility, making it ideal for automotive parts and consumer goods. Its impact resistance ensures longevity in demanding applications.

폴리염화비닐(PVC)

PVC is weather-resistant and durable, often used for outdoor signage and protective covers. Its rigidity makes it suitable for structural components.

폴리에틸렌(PE)

PE is flexible and durable, commonly used in packaging and containers. Its versatility allows for a wide range of applications.

폴리프로필렌(PP)

PP is known for its chemical resistance, making it ideal for food packaging and medical trays. It also offers good heat resistance.

폴리카보네이트(PC)

PC is prized for its high impact strength and transparency, used in applications like protective covers and equipment housings.

What Are the Steps in the Vacuum Forming Process?

The vacuum forming process is straightforward but requires precision to ensure high-quality parts.

그리고 진공 성형 공정⁶ involves clamping, heating, molding⁷, applying vacuum, cooling, and trimming, making it ideal for producing large, shallow parts with simple geometries.

Clamping

The plastic sheet is securely clamped in a frame to prevent movement during heating⁸ and forming.

난방

The sheet is heated to its forming temperature using infrared heaters. The temperature must be carefully controlled to avoid material degradation.

Molding

Once pliable, the sheet is stretched over a mold. The mold can be made from wood, aluminum, or other materials, depending on production volume.

Vacuum

A vacuum is applied to draw the plastic sheet against the mold, ensuring it conforms to the desired shape.

냉각

The formed part is cooled using fans or water to solidify the plastic and maintain its shape.

트리밍

Excess material is trimmed, and the part is finished with any necessary secondary operations, such as drilling or polishing.

What Are the Key Factors in the Vacuum Forming Process?

Several factors influence the quality and success of vacuum-formed parts.

Key factors in vacuum forming include temperature control, vacuum pressure, mold design, material thickness, and cooling rate, all of which affect part quality and production efficiency.

온도 제어

The heating temperature must be precise to ensure the plastic is pliable without becoming too soft or degraded. Each material has an optimal forming temperature (e.g., PVC: 150-180°C, ABS: 160-180°C).

진공 압력

Sufficient vacuum pressure (typically 15-30 inHg) is needed to form the plastic accurately against the mold. Higher pressure improves detail and surface finish.

금형 설계

Molds must include draft angles (2-5°) and venting to allow for easy part removal and uniform forming.

Material Thickness

Thicker materials require higher temperatures and longer heating times, while thinner sheets form more quickly but may lack strength.

냉각 속도

Rapid cooling can cause warping, while slow cooling may extend cycle times. Proper cooling ensures dimensional stability.
