Background -- A time-consuming and often problematic aspect of making nickel electroform tooling is building the mandrels
on which the nickel is deposited.
The design strategy that combines Taguchi approach with two-dimensional flow simulation are then applied to search the sets of geometric parameters, with which the spiral mandrel
sections can yield local maxima of flow uniformity.
A significant difference between traditional presses and these new sleeve presses is the use of a fixed mandrel
at each print station.
When uniform hoopwise circular grids were initially marked on the billets, it was found that after drawing over a mandrel
the bottom side of the markings were seen to have moved forward faster than the top portion of the tubular product [ILLUSTRATION FOR FIGURE 3 OMITTED].
Each Watchwinder uses one or more mandrels
containing a 22B spur gearhead incorporated within a Model 2230 coreless DC motor.

Compatible with all Dremel rotary tools, including the recently released Dremel Stylus(TM), the EZ Lock Mandrel
System is designed for reinforced cut-off wheels -- Dremel's most popular accessory.
BEX's largest hybrid die so far is for 800-mm, four-layer pipe, using its special VSI spiral-mandrel
/lattice-basket die for the HMW-PE core and three spiral mandrels
for layers of PP coatings.
The new Viper systems are 90-ft long, and can accommodate longer mandrels
(molds), which are mounted in line for sequential layup, enabling one ship set to be produced per cycle.
the leading original equipment manufacturer of mandrel
bending equipment, announced today it had added a powerful interactive feature to its web site.
The two main composite fabrication methods are prepreg lay-up in molds for the wings and automated tape-laying on a mandrel
for the fuselage sections.
The large symmetrical blind-side spread allows for use in soft or brittle materials, and the smooth, rounded mandrel
ball is designed to insert easily into the workpiece.
