Materials Needed

• TPU Sheets: Thermoplastic polyurethane sheets that can be molded and shaped under heat.

• Molds: Custom molds designed to create the 3D effect and raised details.

• Laser Cutter or Engraver: For precise cutting and detailing.

• Heat Press: For transferring the label onto the desired surface.

• Adhesive Layer: To help bond the TPU to the fabric or material.

• Protective Film: To protect the design during the heat transfer process.

Steps

1. Design Creation

• Software: Use graphic design software to create a detailed design of your label. The design should consider the 3D effect, with varying heights and depths.

• 3D Modeling: If available, use 3D modeling software to visualize the raised effect and adjust the design accordingly.

2. Creating the Mold

• Custom Molds: Depending on the complexity of your design, you may need custom molds. These can be created using CNC machining or 3D printing.

• Mold Material: Ensure the mold material can withstand high temperatures and repeated use.

3. Cutting and Shaping the TPU

• Laser Cutting: Use a laser cutter to cut the TPU sheet into the desired shape and size based on your design. Ensure precision to maintain the integrity of the design.

• Engraving Details: If needed, use the laser engraver to add fine details to the TPU that will be highlighted in the 3D effect.

4. Molding the TPU

• Heating the Mold: Preheat the mold to the necessary temperature for shaping the TPU.

• Pressing: Place the TPU sheet into the mold and apply heat and pressure. The TPU will take on the shape of the mold, creating the raised, 3D effect.

• Cooling: Allow the TPU to cool in the mold to set the shape.

5. Preparing for Heat Transfer

• Adhesive Layer: Apply a heat-activated adhesive layer to the back of the molded TPU label.

• Protective Film: Place a protective film over the front of the label to protect the design during the heat transfer process.

6. Heat Pressing

• Preheating: Preheat your heat press according to the TPU and adhesive manufacturer's instructions.

• Positioning: Place the item to be labeled on the heat press, position the TPU label on it, and cover with a protective sheet if necessary.

• Pressing: Apply the heat press with the appropriate temperature, pressure, and time settings. This usually involves temperatures around 300-350°F (150-177°C) and pressing for 10-15 seconds.

• Cooling and Peeling: Allow the label to cool slightly before carefully peeling off the protective film.

Tips for Success

• Test Runs: Perform test runs to ensure the mold, heat, and pressure settings yield the desired 3D effect.

• Clean Surfaces: Ensure both the TPU and the surface to be labeled are clean and free of debris for optimal adhesion.

• Safety Precautions: Follow all safety guidelines for using molds, laser cutters, and heat presses.

Applications

• Fashion and Apparel: Adds a premium, high-end look to clothing and accessories.

• Sporting Goods: Durable and resistant to wear and tear, suitable for sports gear.

• Branding and Promotional Items: Eye-catching and tactile, ideal for branding purposes.
