| BASIC MACHINE CONSTRUCTION - Welded, torsion-resistant machine frame in a heavy-gauge steel profile - Exposed surfaces or outer parts treated with either a solvent resistant paint or durable finish - Sound-absorbing side panelling for lower noise levels (approximately 74 DbA) |
| PRINTING TABLE - Heavy-gauge, anodised aluminum surface and aluminum sandwich construction - Vacuum printing area with 1,5 mm diameter holes, pitched every 15 mm on center - Printing table height for off-contact adjustment from 0-40 mm via central handcrank - Fine-adjustment in 3 axes via spindles scaled +/-10 mm and with dial indicator - PCB adapter with table grove and 2 tenon blocks |
| VACUUM SYSTEM - Silent running vacuum blower with high-volume air flow for reliable substrate position hold - Pre-vacuum initiation using two mushroom switches |
| THIEME SQUEEGEE UNIT - Pneumatic change-over or inversion from squeegee to flood-coater and vice-versa for each stroke - Pneumatic squeegee pressure control with automatic adjustment of parallelism to the plane of the printing table, infinitely adjustable for squeegee and flood coater - Angle of squeegee and flood coater infinitely adjustable, independent of the squeegee support beam - Squeegee diagonal positioning - Quick-release squeegee and flood coater iclamps for rapid insertion or removal - One maximum squeegee and flood coater set according to the machine size |
| SQUEEGEE CONTROL - Squeegee control is accomplished by a frequency-controlled and potentiometer adjustable 3-phase gear motor and a toothed drive belt - Squeegee and flood coater speed are infinitely and independently adustable in a range of 0,05 to 0,8 mtrs/sec - Squeegee stroke length is infinitely adjustable using proximity limit switches - Accurate squeegee carriage tracking is performed using dura-synthetic load-bearing rollers |
| PRINTING HEAD AND SCREEN FRAME MOUNTING - The opening and closing of the printing head is mechanically controlled for smooth, non- hesitating travel - Cleaning position extension is switch controlled - Screen frame mounting is accomplished by fast insertion from the front of the press - Screen frame suppoert bars are easily moved to accomodate different frame sizes - The screen frame is mechanically held in place |
| PEEL-OFF DEVICE - The peel-off height is adjustable from 0-5 mm per 200 mm of stroke length, or, a maximum rate of peel lift of 2,5 mm/linear/cm - The peel-off datum or starting point is infinitely adjustable across the squeegee stroke length - The horizontal position while flooding device allows the screen frame to be parallel to the printing table during the flood stroke |
| CONTROL - The THIEME 500E is equipped with a freely programmable controller - A two-position switch toggles between "Set-up" or "Print-cycle" operation - The control panel is attached to the press - Two-hand print cycle start via mushroom switches |
