Operating the Makyu Form Box

Set the heat and time dials for your material.

The temperature light will go from orange to green when the machine reaches the right temperature  

Separate the top tray by lifting the handles and raising until it clicks into place at the top of the sliders – this may require gentle force.  

Peel any protective film off your material  

Place the material on the bottom tray so the edges are covering the grey silicone seal 

Push the top tray down onto the bottom tray so that the material is held in place. The handles click into place to secure it down. 

Lift both the trays, together, to the top for the material to be heated  

Place your mould form on the surface mesh plate 

Ensure your mould has no undercuts, as this will prevent the mould from being able to be released from the formed sheet.

To reduce waste, you can use multiple moulds at one time on a sheet

Press the timer start button. You will hear ticking.

When the ticking has stopped it is time to start forming 

Watch the material for floppiness or elasticity as it heats up.

You will see it becoming more mailable as the sheet starts to droop.

Once the sheet is bowing and soft, push both of the trays down fully over the mould. 

The vacuum cleaner will turn on automatically and create a vacuum sucking the plastic sheet tight over the mould to form the final shape or shapes 

Leave the sheet to cool for 10 seconds 

Once cool, turn off the extraction 

Switch the temperature dial to zero

Unclamp the top tray and lift up, clicking to lock in place at the top of the sliders

Remove the mould from the formed sheet and place on a heat proof mat for processing.

Clean up or trim the sheet as needed 

DO NOT unplug or switch off the machine for 25 mins, as it uses fans to cool down the heater element fully and an orange light will show. Once the orange light goes off, it is safe to switch off the machine. 

Your form is now ready  


Ideal moulds for vacuum forming follow 3 main rules.

Rule #1 

Remove all undercuts 

Undercuts make it difficult to remove templates once they have been formed. Make sure your design doesn’t have any ledges or indents that could stop a template from being removed. 

Rule #2 

Add draft angles 

Draft angles are slopes on the edges of your templates.They help you remove templates from the vacuum form very easily.The slopes on the edges of your forms should point outwards not inwards, so templates come out with little effort. 

Rule #3 

Add air holes 

Adding air holes allows air to flow freely though your design to the vacuum plate. This will help your sheet to form around smaller spaces with greater detail.
