Vacuum flow is essential to the forming operation. When you finish heating the sheet to the forming temperature the vacuum needs to follow right away. This is as you raise the tool. The vacuum hoses and pump, the clamp frame, and the table’s seals each play an essential role. This creates the conditions to form parts that have the right definition.
When using several tools here, you will want to fashion an even vacuum flow. It must come from the table’s primary central vacuum hole, to the underside of all your utensils. To raise every tool off the baseboard, employ spacers for vacuum flow. With some customers, they don’t focus on long production runs. Therefore, they can use double sided foam tape or thin plywood strips. Other options include washers and wire mesh.
More powerful flows and air pressure
Just remember here that raising a mould/tool off the baseboard by 1 mm shall generate a more powerful vacuum flow. The same goes for the air pressure. You may possess an even spread of vacuum holes as well as uniform heating. If so, the vacuum’s pull shall be far more visible. Here, the sheet has the least resilience. It is simpler for the vacuum to drag your sheet above a void as opposed to the tool’s exterior. Here, it will have a cooling effect on your sheet.
