Custom Thermoforming
At CW Thomas, we specialize in custom thermoforming, providing high-quality, cost-effective solutions tailored to meet the unique needs of various industries. From product design to final production, our custom thermoforming services deliver precision and durability while offering flexibility in material selection, shapes, and finishes. With over 75 years of experience, we ensure that every project meets our rigorous quality standards, whether you’re looking for small runs or large-scale production.
What is Custom Thermoforming?
Custom thermoforming is a plastic fabrication process that heats a plastic sheet until it becomes pliable, then molds it into a specific shape using a custom-designed mold. This process can be used to create highly complex shapes and detailed parts that meet the exact specifications of your project. Whether you need vacuum forming or pressure forming, custom thermoforming allows for detailed customization in various thicknesses, materials, and finishes.
Our expertise spans across industries such as automotive, medical devices, aerospace, consumer products, and more. We work with a wide range of materials to ensure that your product not only looks great but also meets performance standards in demanding environments.

Custom Thermoforming for Today’s Industry Leaders
The Custom Thermoforming Process
Our custom thermoforming process involves several critical steps to ensure that every part meets your exact specifications.
1. Design & Material Selection
The first step in custom thermoforming is collaborating on the design and selecting the right material for your part. Depending on the application, we’ll recommend materials that offer the best performance characteristics, such as heat resistance, impact strength, or optical clarity. Popular materials include:
- ABS: Known for its impact resistance and versatility.
- Polycarbonate: Excellent for parts requiring high clarity and heat resistance.
- High-Density Polyethylene (HDPE): Ideal for applications requiring chemical resistance and durability.
2. Thermoforming
Once the design is finalized and materials selected, the plastic sheets are heated to their optimal forming temperature. Depending on your project’s complexity, we’ll use either vacuum forming or pressure forming to create your custom part:
- Vacuum Forming: Uses vacuum pressure to draw the heated sheet against the mold, producing parts with smooth, simple shapes.
- Pressure Forming: Adds air pressure to the process for more complex details and tighter tolerances.
3. Cooling & Trimming
After the plastic takes shape over the mold, it is cooled and then carefully trimmed to remove excess material. Post-processing steps such as CNC trimming or laser cutting are used to achieve precise edges and final dimensions.
4. Finishing & Assembly
We offer additional finishing options, including painting, silk-screening, and adding textures to the surface. For more complex assemblies, we provide part integration services, adding fasteners or mounting hardware if required.

Benefits of Custom Thermoforming
Custom thermoforming offers a range of advantages over other manufacturing methods like injection molding or rotational molding, making it ideal for both small-batch and large-scale production.
1. Cost-Effective for Mid-Size Runs
Compared to other plastic molding processes, custom thermoforming is highly cost-effective for mid-size production runs due to its lower tooling costs and shorter lead times.
2. Design Flexibility
Custom thermoforming allows for intricate shapes and large part sizes that are difficult to achieve with other processes. It also supports various surface textures, finishes, and material choices.
3. Durable & Lightweight Parts
Parts made through thermoforming can be both durable and lightweight, offering the ideal combination of strength and reduced weight, especially in industries like automotive and aerospace.
4. Faster Turnaround
With in-house tooling and streamlined production processes, custom thermoforming offers faster production cycles compared to other methods. This makes it an excellent choice for projects with tight deadlines.
