As a professional injection molding manufacturer, JS Precision knows that moisture content is a crucial variable in the injection molding process. The amount of moisture in the resin can significantly impact the quality of the final product. In this article, we will explore the effects of moisture content on the injection molding process and how JS Precision ensures the proper moisture content for high-quality injection-molded parts.
First, let’s understand what moisture content is and why it matters in the injection molding process. Moisture content refers to the amount of water in the raw material used to mold a part. Most plastics, including resins, absorb moisture from the atmosphere. The moisture content in the resin can affect its physical properties, such as viscosity, molecular weight, and melt flow rate. As a result, it can impact the quality of the final product.
One of the most significant impacts of high moisture content in the resin is the creation of bubbles or voids in the molded part. This can lead to surface defects, such as surface cracking, blistering, and warping. In addition, high moisture content can cause the part to be weaker, more brittle, and prone to failure over time. Therefore, it is essential to ensure that the moisture content of the resin is within a specific range for successful injection molding.
JS Precision uses several techniques to ensure the proper moisture content of the resin. First, we store all our raw materials in a climate-controlled environment to prevent moisture absorption. Second, we use moisture analyzers to test the moisture content of the resin before processing. If the moisture content is too high, we use drying equipment to remove the extra moisture. Lastly, we monitor the moisture content of the resin throughout the injection molding process to ensure consistency and quality.
Moisture content is just one of the many variables that can impact the injection molding process. JS Precision has over 20 years of experience in injection molding and can help customers navigate the complexity of the process. We offer a wide range of services, from design and prototyping to production and assembly. Our team of experts can help customers optimize their designs for manufacturability and cost-effectiveness.
