Its
bulk strength and weight properties are also very favorable when compared to metals, and it can be easily formed using molding processes.
Its
bulk strength and weight are also better than many metals, and it can be more readily molded into complex shapes.
These geometrical techniques address mechanisms that allow the
bulk strength of the solid to exceed the failure criteria in the critical arching dimensions of the flow channel.
In both categories, the insert's
bulk strength is exceeded leading to complete failure and tool breakage.
The ultimate tensile strength of single-end-gated samples is referred to as
bulk strength, while the failure strength of double-end-gated samples with weld lines will be called weld strength.
High
bulk strength, 100% coupling and faster charging lead to more effective, and predictable, blasts, combined with consistently higher productivity.
Figure 4 shows that for heating and welding pressures of 0.31 MPa, even long heating times could not improve the average weld strength beyond [similar to]16 MPa, which is only 65% of the
bulk strength of HDPE.
For each parameter setting, the weld line strength was measured and related to the
bulk strength via a weld line factor.
