Integral oil valve

The needle valve hot runner system has a wide range of applications in injection molding, and its main uses are as follows:

1. High precision injection molding: The needle valve hot runner system can achieve more precise control of plastic materials, controlling the flow and stop of plastic through the opening and closing of the needle valve to achieve higher injection molding accuracy. This is very important for the production of fine structure and high demand injection molded products, such as electronic product casings, lens components, etc.

2. Multi cavity injection molding: The needle valve hot runner system is particularly suitable for multi cavity injection molds. By independently controlling the needle valve of each chamber, independent control of injection molding cycle, temperature, and flow can be achieved for different chambers. This allows for the simultaneous production of multiple injection molded products while maintaining consistency in the plastic materials in each chamber.

3. Plastic flow channel control: Due to the opening and closing control of the needle valve, the needle valve hot flow channel system can effectively control the flow path and filling method of plastic materials. This enables better control of the filling, curing, and shrinkage processes of the product, reduces defects, and improves the quality and appearance of the product.

4. Injection molding of high-temperature materials: Due to the precise temperature control provided by the needle valve hot runner system, it is an ideal choice for injection molding of high-temperature thermoplastic materials. These high-temperature materials need to maintain a molten state and have appropriate fluidity at higher temperatures, and the needle valve hot runner system can provide reliable temperature control to meet these requirements.

In summary, the needle valve hot runner system is widely used in injection molding, including high-precision injection molding, multi cavity injection molding, plastic flow control, and high-temperature material injection molding. It can provide more precise injection molding control, improve product quality, increase production efficiency, and meet special requirements for the injection molding process.
