Description
The D9801 Sudoplast is a welder for polyethylene film 0.1–0.25 mm thick and up to 280 mm long, for making packaging, made by IEMI in Bucharest and designed at the ICE research institute in Bucharest [1].
ICE’s laboratory for electronic instruments for measuring non-electrical quantities designed approved prototypes for many branches of the economy: strain gauge equipment (some configurations were exported to East Germany in 1971–1974 and 1977–1989), vibration meters, dimensional gauges, ultrasonic non-destructive testers, geophysical well-logging equipment and railway equipment [1]. Its designs were made in series at IEMI (27 types) and at the Precision Mechanics Enterprise (5 types), or in ICE’s microproduction workshop (45 types) for small series and one-off models [1].
IEMI’s production table lists 177 units made in 1971–1976 [2].
Annex III.2.13 calls the film polystyrene in one place and polyethylene in another. The welding time, set according to the film thickness, ran from 0.5 to 2.5 s on a dial marked 1 to 10; the resistive strips of the jaws, fed with less than 24 V AC, reached 100 °C ±20% and drew up to 210 W [3].
