Causes and Solutions of Edge Overflow During Injection Molding of TPE Materials

During the injection molding process, certain challenges can arise, such as edge overflow, which can result in product defects and waste. In this article, we will discuss the causes of edge overflow during TPE injection molding and explore the solutions that JS Precision offers to tackle this issue.

Causes of Edge Overflow During TPE Injection Molding

Edge overflow refers to the excess material that spills over the edge of the mold during the injection molding process. This can be caused by several factors, including:

1. Improper mold design: If the mold design is not optimized for TPE materials, it can cause flow imbalances that result in edge overflow.
2. Inadequate injection pressure: If the injection pressure is too low, the material may not fill the mold completely, resulting in edge overflow.
3. Poor temperature control: TPE materials are sensitive to temperature fluctuations, and if the temperature is not controlled properly, it can cause flow imbalances and edge overflow.
4. Insufficient venting: If the mold is not properly vented, it can cause air pockets to form, which can lead to flow imbalances and edge overflow.

Solutions to Edge Overflow During TPE Injection Molding

At JS Precision, we have a range of solutions to tackle edge overflow during TPE injection molding. These include:

1. Optimizing the mold design: Our team of experts can work with you to design a mold that is optimized for TPE materials, ensuring that the flow is balanced and reducing the risk of edge overflow.
2. Adjusting injection pressure: We can adjust the injection pressure to ensure that the material fills the mold completely, reducing the risk of edge overflow.
3. Temperature control: Our state-of-the-art equipment allows us to precisely control the temperature during the injection molding process, preventing flow imbalances and reducing the risk of edge overflow.
4. Improving venting: We can improve the ventilation in the mold to prevent air pockets from forming and reduce the risk of edge overflow.
