How to adjust injection pressure to Improve part performance and durability?
Adjusting the injection pressure, higher injection pressure, pack pressure, linear pressure, and the filling phase of the injection molding cycle is crucial for improving the performance and durability of the parts produced in the case of a piston injection molding machine. Here are a few methods to consider:
Multi-Stage Injection:In this method, the injection process is divided into multiple stages, each with a different injection pressure. The first stage controls the gate, the second stage controls the main body, the third stage fills the product to about 95% of its capacity, and then the pressure is maintained to complete the product.
Injection Speed Controls: The injection speed controls the melt filling rate. The injection pressure serves as a guarantee for this filling rate. The injection position controls the melt flow position, while the holding pressure is used to adjust the product weight, size, deformation, and shrinkage.
Proper Injection Pressure Selection: Selecting the right injection pressure based on the mold temperature, storage temperature, material flowability, product thickness, and complexity is crucial. Higher injection pressures are recommended for more complex shapes and longer processes, while lower pressures are recommended for materials with good flowability.
Conclusion
Understanding and controlling injection pressure is key to the successful production of high-quality plastic injection molded parts. A combination of high-quality injection molds and experienced injection molding company is required to ensure that the injection pressure is set correctly and that the process results in high-quality products.
