摘要:
An automatic apparatus for in-line cleaning of moulds for tyres comprises a nozzle (2) suitable for sending a cleaning jet onto the moulds (1a, 1b), and a manipulator robot (22) able to guide the nozzle (2) for cleaning the moulds (1a, 1b) according to the tread pattern and according to images of the moulds (1a, 1b) supplied by detecting means (10).
摘要:
A container-fabricating apparatus (100) comprises an injection head (101) establishing fluid communication between an injection fluid port (106) disposed therein and a preform disposed in communication with a nozzle (108) of said injection head (101), and a stretching rod (111, 211) mobile between a position projecting from said injection head (101) through said nozzle (108) and a substantially retracted position; said apparatus (100) The apparatus (100) further comprises a cleaning chamber (113) at least partially defined by a hollow, elongate housing (114) contiguous with and extending from said injection head (101, 201), a plurality of cleaning chamber ports (115A, 115B) in a wall of said housing (114) establishing fluid communication with said cleaning chamber (113), said stretching rod (111) being substantially disposed within said cleaning chamber (113) when disposed in said substantially retracted position.
摘要:
The process of preparing a middle ear prosthesis of polymeric material by injection moulding technology according to the presented invention is characterized by drying the thermoplastic polymer granules, preferably high density polyethylene or polyamide or polysulphone, at a temperature in the range of 60 to 150°C for a period of 2 to 8 hours. Subsequently granules are plasticized and then injected at a temperature between 180 and 400°C into the mold heated to a temperature between 60 and 150°C. Then obtained moulder is cooled and in the final stage it is hermetically packed in a vacuum and sterilized. In addition, the granules of the thermoplastic polymer composite are used, obtained by addition of bactericidal additive introduced into the thermoplastic polymer granules, preferably a silver powder with a particle size from 15 to 100 nm, in an amount of 0.1 - 3 wt %.
