SealWerks offers specialized vacuum forming services designed to produce precision 3D thermoplastic parts. Our custom vacuum forming services excel in creating high-quality plastic components with detailed precision and controlled tooling costs. With our ISO-certified manufacturing processes, we cater to industries with stringent hygiene standards, such as medical devices and food service packaging, ensuring consistent quality and reliability.
Vacuum forming relies on a vacuum to draw a thermoplastic sheet over and into a mold, removing trapped air so the material conforms to the mold’s precise shape and detail. This technique is ideal for creating detailed, custom parts in various applications, offering a cost-effective and efficient solution for producing components with both flexible and rigid characteristics. While vacuum forming uses a slightly different process, it renders similar results to thermoforming.
Vacuum forming is an essential manufacturing process for creating a diverse array of products across various industries. This method produces vacuum-formed parts that are both functional and aesthetically pleasing. By utilizing thermoplastic parts, companies can achieve flexible and rigid solutions tailored to specific needs. These applications benefit from the precision and versatility of vacuum forming, ensuring high-quality outcomes that meet strict industry standards.
Vacuum forming offers unparalleled flexibility in manufacturing, allowing for the creation of intricate and complex flexible plastic shapes unattainable by many other processes. It is not only cost-effective but also known for its speed and efficiency, offering fast turnaround times to meet tight production schedules. SealWerks is capable of helping you with your next prototype to medium to large production runs. Expert manufacturers guide you through design, engineering, and production, leveraging industry knowledge to produce parts that meet precise specifications while eliminating waste and minimizing costs.
Plastic Heating: Heat a thermoplastic sheet until it reaches a pliable state, prepared for molding into complex configurations.
Vacuum Application: Employ vacuum pressure to draw the heated sheet snugly against the mold, forming the desired shape with high precision. The vacuum ensures air is evacuated effectively to eliminate imperfections.
Stabilizing and Finishing: Allow the formed part to stabilize, retaining its new shape. Trim and finish to exact specifications, ensuring seamless integration into its intended application.
Vacuum forming utilizes negative pressure, drawing air through tiny channels in the mold, especially at critical areas like corners. This ensures the flexible film precisely conforms to the mold’s shape. Once the film is formed around the mold, the vacuum gradually releases until the film is removed.
The vacuum starts from a central point on the mold and removes air between the mold surface and film, allowing it to adhere to complex shapes. Material type and thickness dictate forming limitations, yet vacuum forming often serves as a cost-effective alternative to pricier methods.
Key Considerations
Typically, vacuum-formed parts have open sides, which can be enclosed by welding or heat sealing. Additional features can be attached to enhance functionality, such as for air or liquid containment.
