Oven Prep
-
Inspection of die upon arrival, all parts are checked for OEM alignment and/or original markings.
-
Removal of the top end of the die (Lip set- top pin, bushing, etc.)
-
Removal of all OD/ID heaters and thermocouples.
Burn Off and Pre-heating:
-
Die is placed in an oven to bake all existing poly from the machine. Can also provide a “hot” disassembly to remove seals and/or inspect for carbon build-up.
Bottom-half Disassembly
-
Careful disassembly of the lower half of the die, spiral pins, die body, feed blocks, etc.
-
Inspection of all parts during disassembly to check for any leaks or damages within the die.
Die Cleaning
-
ALL surfaces such as flow areas, sealing surfaces, and exterior parts are cleaned BY HAND with no use of power tools (not including flow ports and threaded holes).
-
No power tools are used on critical faces to promote the longevity of flow and sealing surfaces.
Refurbishment(If necessary):
-
After cleaning, parts are stripped of plating from all surfaces.
-
Once stripped, parts are cleaned and put into a lathe to receive a mirror-like finish on all surfaces. (8-16 RMS)
-
Multiple plating options include Hard Nickel, Hard Chrome, Armoloy Chrome, PVD, and more.
-
If necessary, we can machine any faces/surfaces to repair damaged areas.
Final Assembly
-
Once all parts have been thoroughly cleaned and inspected, the parts are wiped with alcohol and staged for assembly.
-
All parts are assembled to OEM torques/tolerances.
-
Dies are gauged within .001, and the information is then passed along to the customer for their records.
