In the case of softer GLS materials, it may be necessary to use a more aggressive sprue puller such as a pine tree design (Figure 10). If the product design requires a sprue gate, a hot sprue is preferred over cold because it reduces scrap, decreases cycle time, and allows for easier processing.

The shear thinning behavior of SBCs should be considered when designing injection molds and also when setting mold conditions during processing. Injection Molding: Part Design Injection Molding: Mold Design

Sprue puller designs vary with the hardness of the material. The different sprue designs possible and their relative dimensions are shown in Figures 4 through 7. In addition, Table 3 shows the typical hardness range for which a particular sprue design is applicable.
