Custom Thermoforming Made Easy

Scale: Thermoforming is an ideal manufacturing process for medium to large run sizes of various products, especially large parts of up to 96’’ x 144’’ x 40’’. The process can also combine various parts into one assembled component. The finished product comes color-matched with many material options.

Cost: Thermoforming is a cost-effective means of producing larger parts compared to other manufacturing processes; as part size increases, thermoforming costs are less than injection molding costs. Producing a single-sided thermoforming tool is less expensive than a double-sided injection mold.

Efficiency: Thermoforming is a significantly less time-consuming process than injection molding. On average, injection molding takes 12-16 weeks for production tooling. Choosing thermoforming for the same project can cut that time in half, as thermoforming averages a production tooling time of just 6-8 weeks. This makes thermoforming ideal for projects requiring a quick turnaround.

There are many benefits of plastic thermoforming including cost effectiveness, design flexibility, material efficiency, fast production timelines, and product durability. 

• Cost-Effectiveness: Plastic thermoforming typically involves lower tooling costs compared to other plastic molding processes like injection molding, making it ideal for small to medium production runs.
• Design Flexibility: The thermoforming process allows for the creation of complex shapes and designs that can be customized to specific requirements, including varying wall thicknesses, textures, and finishes.
• Material Efficiency: Thermoforming uses a wide range of thermoplastics, optimizing material use based on application needs, resulting in less waste and more efficient production.
• Speed and Efficiency: The quick production cycle of plastic thermoforming speeds up the manufacturing process, benefiting industries needing fast turnaround times.

Durability and Strength: Depending on the material, thermoformed products can offer excellent durability and strength, suitable for both lightweight and heavy-duty applications.

Common thermoformable materials include:

• Acrylonitrile Butadiene Styrene (ABS): Known for its toughness and impact resistance.
• Polyvinyl Chloride (PVC): Available in both flexible and rigid forms, used in packaging and construction.
• Polycarbonate (PC): Renowned for its strength and transparency, often used in eyewear and electronics.
• High Impact Polystyrene (HIPS): Used in food packaging and display trays.
• Polyethylene Terephthalate (PET): Commonly found in beverage bottles and food containers.
• Polymethyl Methacrylate (PMMA): Also known as acrylic, used for clarity in displays and signage.

These thermoformable materials are popular in packaging, automotive, medical, consumer goods, and construction industries due to their versatility and ease of processing.

A thermoforming machine shapes plastic sheets into desired forms using heat, molds, and pressure or vacuum. Here are the key steps involved:

1. Heating: A thermoplastic sheet is loaded into the thermoforming machine and heated until pliable using infrared heaters or other elements, ensuring uniform temperature.
2. Forming: The heated sheet is positioned in the forming station and shaped over or into a mold using vacuum, pressure, or mechanical force.
3. Cooling and Setting: The formed plastic is cooled in the mold to solidify it, then removed manually or automatically.
4. Trimming and Finishing: Excess material is trimmed, and additional steps like drilling, painting, or labeling may be applied.
5. Quality Control: The final product undergoes quality checks to ensure it meets specifications and standards.

Thermoformed plastic parts offer significant advantages over metal parts, including:

1. Weight Reduction: Thermoformed plastic parts are generally lighter than metal, ideal for automotive and aerospace industries.
2. Cost Efficiency: Plastic materials  are typically less expensive than metals and molds are quicker to produce, which result in significant cost savings.
3. Design Flexibility: Thermoforming allows for the creation of complex designs that can  be easily modified and customized, making them ideal for prototyping and short-run production.
4. Corrosion Resistance: Unlike metals, many plastics are naturally resistant to corrosion and do not require additional coatings or treatments to protect against rust or oxidation.
5. Insulation: Thermoformed plastics  provide better thermal and electrical insulation properties.
6. Simplified Manufacturing: The thermoforming process integrates multiple features, reducing assembly needs and labor costs.
7. Aesthetic Options: Thermoformed parts coe in a wide range of colors, textures, and finishes  without the need for additional painting or surface treatments.  Some thermoformed plastics are naturally transparent which make them ideal for products like display cases, lenses, or protective covers.
8. Durability: Certain thermoformed plastics are  impact resistant and can absorb and dissipate energy, resulting in a highly durable product.
9. Noise Reduction: Thermoformed plastic parts help reduce noise and vibration.
10. Sustainability: Many plastics are recyclable and have a lower environmental impact compared to metalworking.

These benefits make thermoformed plastic parts an attractive alternative to metal parts in various applications, offering advantages in terms of cost, weight, design flexibility, and more.

Thermoforming machines can be categorized based on their forming methods and production scale:

1. Vacuum Forming Machines: Primarily used for simpler vacuum forming processes.
2. Pressure Forming Machines: Utilized for more detailed and complex shapes using both vacuum and pressure.
3. Twin-Sheet Thermoforming Machines: Form two plastic sheets simultaneously, which are then joined to create hollow parts.
4. Roll-Fed Thermoforming Machines: Designed for high-speed production using rolls of plastic material, ideal for large-scale production.

Each type of thermoforming machine is tailored to specific materials, designs, and production volumes, making the choice of machine crucial in the manufacturing process.
