A successful hot runner mold application project needs many links to guarantee. Existem dois fatores técnicos mais importantes. Um deles é o controle da temperatura do plástico, o outro é o controle do fluxo plástico.
1. Controle de temperatura do plástico
The control of plastic temperature is very important in the application of hot runner mould. Many processing and product quality problems in the production process are directly due to poor temperature control of the hot runner system. Por exemplo, the quality of the product gate is poor when the hot needle gate is used in the injection molding, the valve pin is difficult to close when the valve gate is formed, the filling time and the quality of the parts in the multi-cavity die are not consistent, e assim por diante. Hot runner systems with multi-area temperature control should be selected as far as possible to increase flexibility and resilience.
- Control of plastic flow
Plastics should be balanced in the hot runner system. The gate should be opened at the same time so that the plastic is filled with each cavity synchronously. For parts of the weight difference between the FAMILY MOLD to carry out the design balance of the size of the sprue. Por outro lado, there will be some problems such as insufficient filling and holding pressure of some parts, excessive filling and holding pressure of some parts, poor quality of flash edge and so on. The design of hot runner sprue should be reasonable. Too small size filling die pressure loss. If the size is too large, the volume of hot runner is too large, and the residence time of plastics in hot runner system is too long. There are already CAE software such as MOLDCAE that help users design the best runner in the world.
