摘要:
Medical device polymeric tubing segments suitable for forming catheter shafts or as balloon parisons are formed with discrete regions (1,2,3) having different orientation relative to each other. Wall thickness may also be varied of the length of the segment.
摘要:
Procédé de thermoformage d'une bande thermoplastique (1) préchauffée comprenant des moyens pour positionner ladite bande entre la matrice (2) et le poinçon (5) d'un outil de conformation, des moyens pour actionner le poinçon et former un objet, des moyens (8) pour refroidir ledit objet et pour l'éjecter, caractérisé en ce que, de manière à augmenter la cadence de production, ledit poinçon est actionné à l'aide d'un vérin à déplacement contrôlé selon une fonction du temps prédéterminée. Dispositif correspondant pour mettre en oeuvre le procédé.
摘要:
The present invention relates to a process for producing free-flowing, agglomeration resistant amorphous poly-alpha-olefin based adhesive pellets. The process includes (a) extruding the adhesive through an orifice of a die plate immersed in a cooling fluid; (b) cutting the adhesive into a plurality of pellets in the cooling fluid; (c) solidifying the pellets at a temperature range of about 25° C. to about 40° C. for at least 30 minutes; and (d) separating the pellets from the recrystallization fluid and drying the pellets. The pellets harden at least three folds faster than conventionally formed pellets.

The present invention relates to a method and a device for rapidly stress relieving laminated RFID cards sheets (1 ) or individually cut cards (2) so that the effect of card wrap, bending and distortion is reduced. A freezer tunnel (5) is located downstream of a laminator machine. The freezer tunnel (5) uses nozzles (8) to supply a cryogenic liquid in vaporized form. Laminated RFID card sheets (1) are transported through the freezer tunnel (5), where they are exposed to an ambient temperature between -40°C to -100°C during two minutes or less.
