Pressure Forming

Crafting High-Detail Plastic Parts with Thermoplastics

Pressure forming is an advanced type of thermoforming that uses air pressure to push a heated plastic sheet into a mold. This method is particularly effective for creating plastic parts with intricate details, textures, and undercuts that vacuum forming might not achieve. When the plastic sheet reaches the optimal temperature, it becomes flexible. Air pressure is then applied, forcing the plastic into every nook and cranny of the mold, ensuring high-quality detail on the finished part.

This process is ideal for medium to small production runs where the detail and finish of injection molding are desired, but without the high cost associated with injection mold tooling. Pressure forming allows for the production of parts with complex geometries and high-quality finishes at a fraction of the cost of injection molding, making it a cost-effective solution for many applications.

Molds for Pressure Forming: For pressure forming, molds can be made from various materials, including aluminum, which offers durability and longevity far surpassing that of ceramic or wood. Aluminum molds are not only cost-effective in terms of tooling but also provide the flexibility needed for designing complex parts. These molds ensure that the parts produced meet the high standards of detail and quality required by our clients.

Pressure forming is a versatile and efficient method for producing plastic parts that require detailed features and a high-quality finish. It bridges the gap between the simplicity and cost-effectiveness of vacuum forming and the detail-oriented capabilities of injection molding. For projects that demand precision without the high costs of injection molding, pressure forming presents an ideal solution.
