Vacuum Forming

Vacuum Forming

Vacuum forming is a manufacturing process used to shape plastic sheets into various forms and sizes. It is a sort of thermoforming where a plastic sheet is warmed up until it becomes malleable and is then drawn over a mould using a vacuum to generate the required shape.

Vacuum forming in Calgary is a versatile process used in various industries, including packaging, automotive, aerospace, and consumer goods. It is commonly used to create trays, containers, blister packs, automotive parts, and point-of-purchase displays. The process offers several advantages, including cost-effectiveness, rapid production, and the ability to create complex shapes with relatively low tooling costs compared to other manufacturing methods.

Advantages of Vacuum Forming in Calgary

Vacuum forming offers several advantages in Calgary, as well as in any other location. Here are some specific benefits of vacuum forming in Calgary:

  1. Cost-Effectiveness: Vacuum forming is a relatively cost-effective manufacturing process compared to other methods like injection moulding or CNC machining. The tooling costs for vacuum forming are generally lower, making it an attractive option for producing low to medium-volume parts or prototypes in Calgary.
  2. Rapid Prototyping and Production: Vacuum forming, Calgary, allows quick prototyping and production turnaround times. The process is relatively fast, especially for smaller and less complex parts. This speed can be advantageous in Calgary’s competitive business environment, enabling companies to iterate designs and bring products to market quickly.
  3. Customization and Design Flexibility: Vacuum forming offers excellent design flexibility, allowing for the production of complex shapes and intricate details. It is possible to create parts with undercuts, texture, and varying thicknesses. This flexibility benefits businesses in Calgary looking to develop unique and customized products.
  4. Material Options: Many thermoplastic materials can be used for vacuum forming, including ABS, polystyrene, PETG, PVC, and more. These materials come in different colours, textures, and finishes, enabling businesses in Calgary to choose the most suitable material for their specific application requirements.
  5. Versatility in Applications: Whether it’s producing packaging solutions, automotive components, point-of-sale displays, or industrial parts, vacuum forming in Calgary can meet diverse manufacturing needs.
  6. Local Availability: Calgary has a well-developed manufacturing industry and a network of suppliers and service providers that support vacuum forming. This local availability of expertise, materials, and equipment can facilitate smoother production processes and quicker project completion.

Vacuum Forming Process

Here’s a step-by-step overview of vacuum forming Calgary process:

  1. Mould Preparation: A mould or tool is created with the desired shape. The mould can be made from wood, aluminium, or composite materials.
  2. Heating the Plastic Sheet: A plastic sheet, typically made of materials like ABS (Acrylonitrile Butadiene Styrene) or polystyrene, is clamped or secured in a frame above or between heating elements. The sheet is heated until it reaches the desired temperature, becoming soft and pliable.
  3. Forming Station: Once the sheet is heated, it is moved to the forming station, which typically consists of a vacuum table and a mould. The mould can be male or female, depending on the desired shape. The mould is placed on the vacuum table, and the sheet is positioned over it.
  4. Vacuum Application: The vacuum is applied to the mould, creating a pressure difference between the two sides of the plastic sheet. The atmospheric pressure on the mould side of the sheet forces the heated plastic to conform to the shape of the mould, resulting in the desired form.
  5. Cooling and Solidification: After the plastic has taken the shape of the mould, the vacuum is released, and the sheet is cooled. It helps solidify the plastic and maintain its shape. Cooling can be done through various methods, such as fans, water sprays, or cooling chambers.
  6. Trimming and Finishing: Once the plastic has cooled and solidified, it is removed from the mould. Any excess material is trimmed off, and additional finishing operations, such as cutting, drilling, or machining, can be performed to achieve the final product.

Commonly Used Materials in Vacuum Forming

Vacuum forming can be performed using various thermoplastic materials. Here are some commonly used materials in vacuum forming:

  • Acrylonitrile Butadiene Styrene (ABS): ABS is a popular thermoplastic material known for its strength, impact resistance, and affordability. It is commonly used in vacuum forming for applications such as automotive parts, electronic enclosures, and consumer goods.
  • Polystyrene (PS): Polystyrene is a versatile material with good clarity and excellent formability. It is widely used in vacuum forming for applications like food packaging, disposable trays, point-of-sale displays, and lightweight parts.
  • Polyethene (PE): Polyethylene is a lightweight and flexible material with good chemical resistance and insulation properties. It is often used in vacuum-forming applications such as protective packaging, trays, and containers.
  • Polypropylene (PP): Polypropylene is a durable and heat-resistant material with good chemical resistance. It is commonly used in vacuum forming in Calgary for applications like automotive components, medical trays, and industrial parts.
  • Acrylic (Polymethyl Methacrylate or PMMA): Acrylic is a transparent thermoplastic material known for its optical clarity, high gloss, and excellent weather resistance. It is a popular choice for vacuum-forming applications that require transparency, such as display cases, signage, lighting fixtures, and architectural components. Acrylic offers good impact strength and can be easily machined and polished.
  • Polycarbonate (PC): Polycarbonate is a solid and impact-resistant thermoplastic material with excellent clarity. It is known for its high strength-to-weight ratio and resistance to extreme temperatures, making it suitable for applications that require durability and transparency. Polycarbonate is commonly used in vacuum forming for safety helmets, protective shields, automotive parts, and machine guards.
  • High-Density Polyethylene (HDPE): HDPE is a rigid and durable thermoplastic material with excellent chemical resistance. It has a high strength-to-density ratio, making it strong yet lightweight. HDPE is often used in vacuum forming in Calgary for applications such as industrial containers, storage bins, automotive parts, and agricultural equipment. It is also FDA-approved for food contact applications, making it suitable for packaging and food processing industries.

Why Choose Us?

Choosing Acrylic Plexiglass for various applications, such as vacuum forming in Calgary, offers several advantages:
