How to Accurately Calculate The Injection Molding Cycle?

In the injection molding industry, accurately calculating the molding cycle is not only the key to evaluating production efficiency, but also an important basis for providing customers with accurate quotations. A reasonable molding cycle not only concerns the control of production costs, but also directly affects customer satisfaction and market competitiveness. This article will provide you with a detailed introduction on how to accurately calculate the injection molding cycle and explore its important role in enterprise pricing.

The injection molding cycle, which refers to the unit time required to complete an injection molding process from start to finish, mainly consists of the following stages:

1.Closing time: The time required for the mold to fully close from the open state.

2.Filling time: The time required for molten plastic to be injected into the mold cavity and filled.

3.Holding time: To ensure that the plastic is fully cured in the mold, a certain amount of pressure is applied to the mold for a certain period of time.

4.Cooling time: The time required for plastic to cool and solidify in the mold, including plasticization time.

How to accurately calculate the injection molding cycle

1.Understand the material properties

The melting temperature, flowability, and curing time of different plastic materials vary, which directly affect the injection molding cycle.

2.Optimize mold design

By optimizing mold design, such as improving cooling circuits and increasing cooling efficiency, the cooling time can be significantly shortened, thereby shortening the entire molding cycle.

3.Comprehensive consideration of injection molding machine performance

When choosing an injection molding machine, its performance parameters should be comprehensively considered based on production needs to ensure efficient production while also meeting product quality requirements.

4.Actual operation and adjustment

In the actual production process, it is necessary to adjust the molding cycle in real time according to the specific situation. By monitoring various parameters during the production process, such as melt temperature, mold temperature, injection speed, etc., timely adjustments are made to optimize the molding cycle.
