| Forming: |
 |
Mechanical Pressing (up to 250 tons); qty.: 51
- utilized for high volume production
Extrusion (up to 1 in. diameter and 12 in. length);
qty.: 3
- utilized for shapes requiring lengths greater than 2 in.
Cold Isostatic Pressing (CIP)
- (up to 6 in. diameter and 20 in. length); qty.: 7
- utilized when, due to the size or complexity of the shape
or due to time and/or volume
- considerations, conventional
mechanical pressing is not feasible
Molding - utilized for non-ceramic materials |

Grinding (sintered:hard and green:soft): flat-th
/ od / id / form / drilling / milling
Slicing: (from 0.005 thick and 6 in. diameter)
Lapping: finish 0.2 – 0.4 µm
Polishing: finish 0.1 –0.2 µm (std.)
Optically Polished: finish 0.075 – 0.1 µm
(less than 50 angstroms)
Hot Isostatic Pressing (HIP): (up to 1500 C and up
to 30,000 psi)
- utilized for ferrite in magnetic heads in contact with tape,
which require a dense
- material, virtually without
pores and resistant to abrasion. also, due to near
- theoretical densities achieved,
magnetic properties of most materials are
- significantly improved
Magnetizing: (axial, radial and multi-pole up to 10,000
oersteds)
Automatic & Manual Electrical Sorting/Grading:
up to 10,000 parts/hour
Annealing: magnetic and thermal
Tumbling: edge rounding (prevents sharp edges from
cutting wire insulation)
