Abstract
A system and method are provided in which the rate of material flow to a plurality of gates can be controlled by a single controller. According to one embodiment, material is provided to first and second runners, the first runner comprising a plurality of distribution nozzles, and the flow to the first runner being controllable independently of the flow to the second runner.
Claims24
An injection molding system comprising:
- a manifold for distributing injected material to first and second runners, wherein the first runner leads to first and second gates;
- and
- a controller to control the rate of material flow through the first runner at a point of control away from the first and second gates independently of the second runner, the controller controlling the rate of material flow according to an algorithm using a value indicative of a sensed condition of the injected material.
A distribution system for distributing melt flow comprising:
- a first runner comprising a plurality of distribution nozzles delivering the melt flow to a plurality of gates;
- a second runner comprising at least one distribution nozzle;
- and
- a controller capable of controlling the material flow to the first runner at a point of control away from the gates independently of the second runner.
An injection molding system comprising:
- a manifold for distributing material to a runner;
- a plurality of gates coupled to the runner;
- and
- a controller positioned in the runner to control the flow of material to the plurality of gates at a point of control away from the gates, the controller controlling the rate of material flow according to an algorithm using a value indicative of a sensed condition of the injected material.
An injection molding system comprising:
- a manifold for distributing injected material to first and second runners, wherein the first runner leads to first and second gates and the second runner leads to one or more other gates;
- and
- a controller to control the rate of material flow through the first runner based on a sensed condition of the material leading to the first and second gates independently of a condition of the material leading to the other gates.
An injection molding system comprising:
- a manifold for distributing injected material to first and second runners, wherein the first runner leads to first and second gates and the second runner leads to one or more other gates;
- and
- a first controller to control the rate of material flow through the first runner based on a sensed condition of the material;
- a second controller to control the rate of material flow through the second runner based on a sensed condition of the material.
