  • Method for manufacturing a linear actuator
    Patent number: 8819940
    Abstract: A method for manufacturing a linear actuator includes inserting a portion of a thrust member of the actuator into a casting portion of a molding apparatus. The casting portion includes a model screw member having a threaded portion. A molding material can be added into the cast portion to overmold a nut to the thrust member. Thus, the nut will include a threaded portion on an internal circumference mateable with the threaded portion of the model screw member. The overmolded nut and thrust tube member may be coupled to a screw shaft of the actuator, such that the threaded portion of the nut mates with a threaded portion of the screw shaft.
    Type: Grant
