NOZZLE
Features and instructions
- Hot runner system nozzle is designed according to different product requirements. There are two types of open gate and valve gate hot nozzles.
Advantages of hot runner system
- Reduction in scrap and maunal operstion such as sprue trimming and scrap crushing.
- Cycle time reduction : hot runner could help runner freeze more quickly and simplify molding process such as runner removing.
- Make the most of machine capability : less reaction force from hot runner system, shorter cycle time, less clamping force.
- Engry save : Engry is spent on preparation stage to heat up maniflod and materail. But there will be less engry input when molding process begins.
- Simplify mold design and enable automated production.
- For big part, hot runner system could help solve pressure loss issue when using cold runner system.
- A less pressure loss could help injection more efficiently.
- Continuous packing effect could help reduce part shrinkage.
- By temperature control and valve gate control, hot runner system could make flow balance more easily.
- A sequence controled valve gate system could help produce a weld line free part.
OPEN GATE
- Simple and easy to use.
- According to the necessary, we can choose by using Sprue gating or Pin-point gating nozzle.
- The sprue nozzle is the most popular type. Not only it's suitable for almost all of the plastic material but also it provides easy color change.
- The pin-point gating nozzle：It provides good gate mark, reduction in raw materials consumption, and reduction of finishing work on molding.
- There are AESB, ANPR, ANPT, NL-ANPT and other specifications.
VALVE GATE
- No stringing, no drooling, no residue in the gate. Very good gate mark.
- Because it can provide bigger gate size, therefore it is very suitable for big size injection molding. Also lower injection pressure and less stress during molding.
- A sequence controlled valve gate system could help produce a no weld line part.
- We provide AVMT, SVDT, NL-SVDP, SVG types.
