Professional injection molding machine injection molding analysis
1. Hot runner
An alternative to the traditional "cold" runner and runner system is hot runner. For the hot runner, the general process is the same, but in this case, the plastic should be kept heated so that it will never solidify in the runner. This speeds up production and eliminates the need to collect and recycle cooled plastic. To learn more about the advantages and disadvantages of hot runners, check out our blog here.
2. What is a gate?
The gate is the channel through which the molten plastic flows into the mold of the injection molding machine. Specifically, the gate is the entrance of the molten plastic, which is the vertical channel through which the plastic then flows into the runner and the gate. Generally, the entire assembly is often referred to as a runner. When looking at the various parts of the toy model, it is easy to see the entire system. The actual part is the final product produced in the cavity, and the connecting plastic is the cooling material inside the runner and runner. The entire structure can be seen in the plastic component below.
3. Gating and recycling
After removing the finished product from the sprue, you will find that you have a lot of plastic waste. This is generally regarded as one of the disadvantages of injection molding in this way. However, this residual amount is not without use. It can be collected, melted and recycled into usable plastic in preparation for the injection molding process again.
