on the Day:

* detach vacuum cleaner hose * remove vacuum cleaner bag * attach vacuum molding table hose to vacuum cleaner * clean heating rods with paper and isopropanol * inspect all visible cables for visible damages * connect powercable with socket * get IR-thermometer, stopwatch, notepad and pen * go to toilet

right before the first molding

* clamp sheet * position molds * plug in vacuum cleaner * switch on oven-thermometer, adjust set-temp to 150°C * unlock main switch (from here on you must stay in direct vicinity of the machine at all times!) * check if heating elements are switched off * check if vacuum cleaner switch is off * check if the three automatic Over-Current circuit breakers are on * check if Residual-Current Circuit Breaker is on * switch on main switch * press test button on RCCB * switch RCCB off and then to on position * move up clamping frame in heating-position * switch on both oven parts and start the stopwatch * check temperature every 10-20sec * wait until the material is sufficiently soft, saggy and hot * release the clamping frame * have someone write down the exact time from the stopwatch * switch on vacuum cleaner * move clamping frame down on the mold * switch off oven * wait until plastic is cooled below 70° * switch off vaccuum cleaner * release plastics from mold

for any other molding after the first

* clamp sheet * position molds * check if heating elements are switched off * check if vacuum cleaner switch is off * check if the three automatic Over-Current circuit breakers are on * check if Residual-Current Circuit Breaker is on * move up clamping frame in heating-position * switch on both oven parts and start the stopwatch * check temperature every 10-20sec * wait until the material is sufficiently soft, saggy and hot * release the clamping frame * have someone write down the exact time from the stopwatch * switch on vacuum cleaner * move clamping frame down on the mold * switch off oven * wait until plastic is cooled below 70° * switch off vaccuum cleaner * release plastics from mold

after the last mold of the day

* switch the three automatic Over-Current circuit breakers to off * switch main switch to off * lock main switch (only after this task you are permitted to leave the vicinity of the machine!) * remove molds from the vacuum molding table * unplug vacuum cleaner * remove vacuum molding table hose from vacuum cleaner * reattach vacuum cleaner hose * put in new or old vacuum cleaner bag in vacuum cleaner * unplug the powercable from the wallsocket * store away the vacuum cleaner where it belongs * submit temperatures, timings, stopwatch-readings, useful info and your overall experience via email to vacuumforming@c-base.org
