The method includes the steps of conveying a plastics melt through at least one feed channel into a mold cavity which is delimited by a first mold and a second mold; moving the first and second molds toward one another; removing the at least one diaphragm from the mold cavity; and cutting off a sprue from the at least one diaphragm removed from the mold cavity.
Claims10
A method for producing at least one valve diaphragm for a diaphragm valve, the method comprising:
- conveying a plastics melt through at least one feed channel into a mold cavity which is delimited by a first mold and at least two second molds;
- moving the first mold and the at least two second molds toward one another as the molten plastic is conveyed;
- removing the at least one valve diaphragm from the mold cavity;
- and
- cutting off a sprue from the at least one valve diaphragm removed from the mold cavity;
- wherein the first mold is arranged so as to be stationary, and wherein the at least two second molds are movable with respect to the first mold, wherein a stationary mold is arranged between the at least two second molds, which stationary mold at least partially delimits a feed channel opening into the mold cavity.
