Large POSTMOULD Graphic Quick Tip

Large POSTMOULD Graphic Quick Tip

 

If you’ve ever wondered how to apply POSTMOULD graphics using a heat transfer process, you’re in the right place. At PSI Brand, we’re experts on mould-on graphics for large applications, and we’ve created this short summary to help you find quick tips for POSTMOULD graphic application procedures.

Tools you’ll need

To use a heat transfer process for POSTMOULD graphics applications, you’ll need a propane gas torch with a wide-flame adapter such as RIPACK brand, an air-burnishing tool, burnishing pad and a plastic squeegee.

Instructions

Step 1
Begin by using your propane gas torch to flame the plastic surface using brush-type strokes until you reach a temperature of approximately 70 degrees Celsius.

Note to extend flaming to higher temp such as 110 degrees Celsius for a larger window of application time and /or higher density plastics.

Step 2
Apply the POSTMOULD graphic, starting from one end, by scraping with the plastic squeegee to eradicate any air bubbles. Extreme care is required to ensure that no air is trapped beneath the surface, as this will destroy the graphic during final flaming stages – every part of the graphic needs to be in full contact with the plastic part.

Step 3
Use your burnishing tool to burnish the graphic onto the plastic surface, starting by tracing around the edges of the graphic and paying particular attention to the corners, before then moving to the centre of the graphic.

Step 4
Once the graphic starts to lift at one end, stop burnishing and peel the clear backing away from the plastic, leaving the graphic behind.

Check your application thoroughly for any air bubbles that may have been missed. If you find any, use a knife to prick the bubble and then expel the air with your fingers – this will prevent the air bubble from burning and causing discolouration during the final flaming stage.

Step 5
Finally, use your propane gas torch to flame the graphic one last time, again to a temperature of 70 degrees Celsius or higher. Extended flaming will help the graphic edges to become less prominent, resistant to scratching or being chipped.

Frequently asked questions

Here are some of the most common questions we get when it comes to large POSTMOULD graphics applications.

What is the application process for Type 3 graphics?
The above heat transfer process is ideal for type 3 graphics system applications. Visit our specific page for smaller POSTMOULD graphic applications.

Why use a burnishing tool?
The burnishing tool essentially buffs the graphic onto a plastic surface and will improve the surface finish, surface hardness, durability, and corrosion resistance of your POSTMOULD graphic, to keep it looking brilliant for even longer.

Where to find training for POSTMOULD graphics applications?
We have a range of application videos on our website for our range of POSTMOULD graphics.

Additionally, PSI Brand has created an online training portal where you can learn all about our revolutionary INMOULD and POSTMOULD graphic solutions.
