Abstract
A feed system for an injection molding method and machine includes a first part including a first channel, and a second part including a second channel, the first channel and the second channel forming a molten plastic feed conduit when the first part is located adjacent to the second part. A joint is formed between the first part and the second part along the first channel and the second channel and the joint is one of a sintered joint, a welded joint, and a brazed joint.
Claims14
An injection mold system including a multi-part feed system, the multi-part feed system comprising:
- a first part including a first feed channel;
- and
- a second part including a second feed channel, the first feed channel and the second feed channel forming a molten plastic feed conduit when the first part is located adjacent the second part, wherein a metal-connecting brazed joint is formed between the first part and second part and between the first feed channel and the second feed channel, the metal-connecting brazed joint extends from the molten plastic feed conduit a distance greater than 2 microns but less than 0.2 mm.
An injection mold system including a multi-part feed system, the multi-part feed system comprising:
- a first part including a first feed channel;
- and
- a second part including a second feed channel, the first feed channel and the second feed channel forming a molten plastic feed conduit when the first part is located adjacent the second part, the molten plastic feed conduit including at least one turn having a radius that is between 0 and 2 times a diameter of the molten plastic feed conduit,
- wherein a metal-connecting brazed joint is formed between the first part and second part and between the first feed channel and the second feed channel, the metal-connecting brazed joint extends from the molten plastic feed conduit a distance greater than 2 microns but less than 0.2 mm.
