Abstract
A method includes providing a mold defining a mold cavity for receiving material to be molded into a molded part, positioning an insert at least partially in the mold such that a portion of the insert defines a portion of the mold cavity, and injecting the material into the mold cavity to substantially fill the mold cavity to form the molded part. The molded par can then be removed from the mold and the insert can be removed from the molded part. The mold can include silicone and the insert can include polyoxymethylene.
Claims20
A method comprising:
- providing a mold defining a mold cavity for receiving material to be molded into a molded part, wherein the mold comprises silicone;
- positioning an insert at least partially in the mold such that a portion of the insert defines a portion of the mold cavity, wherein the insert comprises polyoxymethylene;
- positioning a pin in the mold cavity such that the pin extends from the insert and into the mold cavity, wherein the pin defines a shape of a hole of the molded part;
- injecting the material into the mold cavity to substantially fill the mold cavity to form the molded part;
- removing the molded part from the mold;
- and
- removing the insert and the pin from the molded part.
A method comprising:
- providing a mold defining an internal cavity, the internal cavity including a mold cavity for receiving material to be molded into a header for an implantable medical device and including an insert cavity adjacent the mold cavity;
- positioning an insert in the internal cavity so that the insert is entirely contained in the mold, wherein at least a portion of the insert is positioned in the insert cavity, and wherein a surface of the insert defines a portion of a top of the mold cavity for forming a portion of a top surface of the header opposite a bottom surface of the header, wherein the bottom surface is configured to be adjacent to a device housing;
- injecting the material into the mold cavity to substantially fill the mold cavity to form the header;
- removing the header from the mold;
- and
- removing the insert from the header.
A method comprising:
- providing a mold defining an internal cavity, the internal cavity including a mold cavity for receiving material to be molded into a header for an implantable medical device and an insert cavity adjacent the mold cavity, wherein the mold comprises silicone;
- positioning an insert in the internal cavity so that the insert is entirely contained in the mold, wherein at least a portion of the insert is positioned in the insert cavity, wherein a surface of the insert defines a portion of a top of the mold cavity, and wherein the insert comprises polyoxymethylene;
- positioning a pin in the mold cavity adjacent the insert prior to injecting the material into the mold cavity, wherein the pin defines a shape of a set screw hole of the header;
- injecting the material into the mold cavity to substantially fill the mold cavity to form the header;
- removing the header from the mold;
- and
- removing the insert from the header.
