Abstract
In a molding step, at least a first member, which constitutes a liquid supply unit together with a second member, is injection molded by using an injection mold including first and second molds being made openable and closable. In a mold opening step, the first and second molds are opened while leaving the first member, which is injection molded in the molding step, on the first mold. In a first bonding step, a third member constituting the liquid supply unit is bonded to the first member left on the first mold.
Claims12
A method of manufacturing a liquid supply unit to form a liquid passage to supply a liquid to a liquid ejecting head, comprising:
- a molding step of injection molding at least a first member, which constitutes the liquid supply unit together with a second member, by using an injection mold including first and second molds being made openable and closable;
- a mold opening step of opening the first and second molds while leaving the first member, which is injection molded in the molding step, on the first mold;
- and
- a first bonding step of bonding a third member constituting the liquid supply unit to the first member left on the first mold.
A method of manufacturing a liquid ejecting head provided with a liquid supply unit, comprising:
- a molding step of injection molding at least a first member, which constitutes the liquid supply unit together with a second member, by using an injection mold including first and second molds being made openable and closable;
- a mold opening step of opening the first and second molds while leaving the first member, which is injection molded in the molding step, on the first mold;
- a first bonding step of bonding a third member constituting the liquid supply unit to the first member left on the first mold;
- and
- a second bonding step of bonding the second member to the first member having the third member bonded thereto in the first bonding step;
- and
- a third bonding step of bonding a printing element board, which is configured to eject a liquid, to the members bonded in the second bonding step.
