How to work with our materials
These instructional videos provide our recommendations for storing, caring for, and working with our materials. You can download text guides via the links below each video. If you have any questions or need further assistance, consult our FAQ's page, read our fabrication guidelines PDF or contact us directly; we're always happy to help you realise your project.
Cleaning your material
Smile Plastics sheets require little maintenance. Surface dirt can easily be removed using a mild detergent and warm water. Abrasive cleaners should be used with caution. Remember to always follow the manufacturer's instructions and test any cleaning product on a small, inconspicuous area before applying it to the entire surface.
Cutting your materials
Our recycled panels share many of the characteristics of other plastics and composite wood-based boards such as MDF. They can be worked with most woodworking, plastics and metal tools, providing they are kept sharp.
Cutting on the CNC
For CNC cutting, we recommend using a sharp single flute upward cutter ideally with a polished face suitable for plastics. CNC machines cope with feed rates and speeds differently.
Cutting on the wall saw
Most saws can be used to cut Smile Plastics boards, though fine teeth are recommended. We recommend using a wavy set or skip tooth saw to minimise friction.
Refinishing your material
Just like a fine wine, our materials develop character over time, but may show some signs of wear. Refinishing your material is a quick, easy, and effective way to restore its original beauty and ensure it lasts for many more years.
Refinishing HIPS
Spot finishing the Heron colour washes is not advisable; however, you can refinish the entire sheet to reveal a consistent colour. For further guidance, please speak with a member of the Smile Plastics team.
Refinishing PET
Scuffs and minor scratches on the surface can be sanded out using appropriate grades of paper and scotch-brite pads – the selection of which should be determined by the level of refinishing required.
Joining Materials - Adhesives
Smile Plastics materials can be used to fabricate a variety of structures and items, and the joining method needed may vary with the application. Different adhesives will work for different plastic types. We strongly advise you to conduct testing to determine the most suitable adhesive and application method for your specific needs.
Edge Finishing
The edge finish created by different cutting methods can vary. CNC machining using the recommended bit can leave a finished and ready-to-use edge, but there are many more edge options you can explore.
Chamfered Edge
Chamfered and straight edges can be made using table saws, rail saws, or a router and a chamfer bit.
Rollover
Applying even pressure, a rollover edge can be achieved using a router and a rollover bit.
Blade Finishing (Skiving)
We recommend using a very sharp blade to scrape/cut away any burrs or melted plastic.
Hand Deburr
Hand deburring can be a time-consuming process and should be done with patience and care.
Hand Deburr Using a Router
Curved edges or fillets can also be created using a router. Ensure you use sharp tools to minimise heat build up and to give you a clean edge.
Pre-Drilling and Hand-Tightening Fixings
When assembling components, it is crucial to implement proper handling techniques to accommodate thermal expansion effectively. For comprehensive assembly guidelines, please read the PDF and refer to our handling guidelines download.
Storing your materials
Correct storage of your material is essential to maintain quality and usability. Ensure you store your plastic sheets in a cool, dry and indoor environment, away from direct sunlight or areas prone to high temperatures. The sheets will bend if improperly stacked. If bending occurs, then stacking them in the opposite direction will normally return the sheets to their original shape.
Horizontally on a Pallet
Smile Plastics sheets should be fully supported on a level plane to avoid any warping.
On an Angle/A-Frame
An A-frame adds optimal support and stability to material storing.
Further Resources
Our handling guideline resources are not exhaustive and we are continually testing new possibilities with our materials. Please send us your recommendations so we can expand our knowledge of the workability of our products, so we can share ideas and information with our community. For information on how to join our materials, including guidance on adhesives, please refer to our Fabrication guidelines PDF. If you feel unsure about the work or have any further questions, please get in touch.
