Worcester City, who stunned the Sky Blues in the first round, will be at home to Chesterfield if they can sink Mark
Robins's Scunthorpe United at the second attempt after Saturday's 1-1 stalemate at Glanford Park.
It can be used to flu in gaps in the scan data or to repair defects from the physical originals--for example, a crack in a historic ceramic piece or a sink mark
in a plastic moulding.
However, the increased packing pressure does not provide a complete solution for overcoming sink mark
problems or reducing shrinkage.
For example, the severity of sink mark
was referenced by its depth, which could be measured with a surface roughness measuring machine  or with a micrometer .
A sink mark
in thin sections is seen to depend on delay time, mold temperature, melt temperature and gas pressure (in order of declining importance).
In fact, the map pocket strengthening flange on the top edge of the map pocket is in excess of 1:1 (thicker than the nominal wall), which is possible only because the unsightly sink mark
that would otherwise result is prevented by the gas pressure within the microcellular foam melt.
They are said to improve sink mark
removal and reduce weight while preserving structural properties of ABS, LDPE, HDPE, and PP parts injection molded and extruded/coextruded.
Products improve flow, compatibilize mixed/ cycled polymers, reduce molding cycle or increase extrusion rates, and are used for sink mark
elimination and improved weld-line strength.
Overmolding also compensates for any sink marks
in the under-layer.
Compared to unfoamed injection molding, the use of this process minimizes warpage and the probability of sink marks
