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.
A high mold temperature prolongs the molten state of the polymer melt during the injection stage, enabling the melt to more easily fill the rest of the cavity, generally increasing the bulk strength, as well as the weld strength.
High bulk strength
, 100% coupling and faster charging lead to more effective, and predictable, blasts, combined with consistently higher productivity.
The use of high bulk strength explosives, such as heavy AN/FO, and the realization of the associated direct and indirect cost savings, is becoming more common in the mining industry today.
Aluminum increases total energy output, bulk strength and detonation temperature and pressure of the explosive but does not greatly affect the velocity of detonation.
Highlights will include: Orica offers bulk explosives that range from less than half, to almost triple the Relative Bulk Strength
of ANFO with additional flexibility in Velocity of Detonation.
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
Vistis produces over three and a half times the detonation pressure of ANFO at triple the Relative Bulk Strength
For each parameter setting, the weld line strength was measured and related to the bulk strength
via a weld line factor.
