How you decide the parting line?

Question

Accepted Answer

The process of deciding the parting line for plastic molding or die casting dies depends heavily on the final product's design and manufacturing requirements. Here are some key considerations:

#Functionality of the Product: We aim to place the parting line in areas that won’t affect the product's structural integrity or appearance. For instance, we avoid placing it in high-stress or high-wear areas and where there are strict cosmetic requirements.

#Core and Cavity Design Simplicity: A simple core and cavity design reduces the need for side cores and undercuts. This approach minimizes manufacturing complexity and cost while also reducing the potential for alignment issues and mold wear over time.

#Material Flow and Cooling: The parting line placement can affect how the material flows and cools within the mold. By optimizing its position, we can help avoid warpage or shrinkage, ensuring higher product quality.

#Ejector Placement: Proper parting line placement also facilitates efficient ejection of the part from the mold. This allows us to place ejector pins in non-visible areas, minimizing visible marks on the final product.

These considerations help us create a mold design that is efficient, cost-effective, and produces a high-quality product.
