Trying to thread the breech with a hand-held die and die holder
will not be accurate enough.
A die with two parts, specially designed pin shapes and die holder
are the three main sections of ECAP system.
When sizing/depriming is completed, the die is removed, a collet screwed into the die holder
, and the shell holder transferred to the die's position.
Said to be a key technical highlight of the Series 900 is a patent-pending FeatherTouch adjustment in the die holder
and a cartridge-style ball assembly that does not require the loosening of retaining screws to make adjustments.
An experimental rig was specially designed and manufactured, and consisted of a barrel, two piston systems, a die and die holder
and operational control systems.
At the same time, you want to draw the material over the die holder
. So the problem is you want to have the sheet draw in because the more you draw in, the more material you have, the more complex parts you can make.
The "FeatherTouch" adjustment in the die holder
is a cartridge-style ball assembly that does not require the loosening of retaining screws to make adjustments.
Guill Tool & Extrusion Co., West Warwick, R.I., adapted its Feather Touch adjustment of the die holder
and ball assembly (see photo) to micro-tune layers as thin as 0.0005 in.
All of the company's heads offer a patent-pending Feather-touch adjustment in the die holder
, a cartridge-style ball assembly that does not require the loosening of retaining screws to make adjustments.
Features of the MiniMicro die, which the company reports achieves accuracy up to 0.0005 OD of wall thickness, include a FeatherTouch adjustment in the die holder
that does not require the loosening of retaining screws to make adjustments, and a Seal Right System that eliminates leakage between the deflectors and is maintained through self-adjustments, thereby reducing the possibility of errors during assembly.
Its "Flexispiral" crosshead tubing dies have two new features: spiral melt flow and a ball-shaped die holder
. Spirals create even flow while the spherical die holder
, called FeatherTouch, supports the die, allowing wall thickness to be adjusted without loosening a set of retaining screws.
