Twin Sheet Thermoforming Process

How the Process Works

You start the twin sheet thermoforming process by choosing the right plastic for your medical device. The material you pick must be strong and safe for healthcare use. Next, you heat two sheets of this plastic until they become soft and flexible. When both sheets reach the right temperature, you place them into matching molds. These molds shape the sheets into the form you need.

After placing the sheets in the molds, you bring the molds together. High pressure pushes the sheets to fit the mold shapes exactly. This step forms a double-walled part with a hollow space inside. The part cools while still in the molds, which helps it keep its shape and strength. Once the part cools down, you remove it from the molds. You may need to trim or finish the part to make sure it meets your needs.

Tip: Careful control of heat and pressure during the twin sheet thermoforming process helps you get precise shapes and strong parts every time.

Here is a simple breakdown of the steps:

1. Select the right thermoplastic material.

2. Preheat two plastic sheets until they are soft.

3. Place the sheets into matching molds.

4. Press the molds together to shape the sheets.

5. Cool the part in the molds.

6. Remove and finish the part as needed.
