Job description

To fabricate ceramic cores via low pressure injection, high pressure injection, and invested core processes; to work independently to assure smooth product flow through all aspects of core production.

PRINCIPAL ACCOUNTABILITY:

Slurry Makeup and Testing:

• Essential Job Functions:
  • Many different slurries are used; checks pH, viscosity, temperature, and gel times, applies results to specification ranges and determines whether slurries are usable.
  • If needed, modifies slurries to bring into specification without altering slurry with respect to core requirements.
  • Records time, tracks work in progress.

Invested Core Processing:

• Essential Job Functions:
  • Inspects soluble for defects; decides on usability.
  • Assembles soluble patterns which differ for each core configuration; helps develop new assemble techniques.
  • Builds wax shell of assembled pattern.
  • Leaches soluble from wax shell.
  • Builds alpha coated core, attending to surface quality, stucco and adhesion before next layer is applied.
  • Fills remaining cavity with core pack.
  • De-waxes in hot wax tank and fires in furnace.
  • Records time, tracks work in progress.

High Pressure Injection:

• Essential Job Functions:
  • Operates high pressure machines per established process; monitors temperature and pressure.
  • Monitors inventory levels of high pressure ceramic mix and orders materials as needed.
  • Assists in the preparation of high-pressure ceramic mix.
  • Places green state cores in sand-filled trays, transports trays

Low Pressure Injection:

• Essential Job Functions:
  • Operates low pressure machines per established process specifications to produce cores of acceptable quality.
  • Removes binder by using either flaming, ovens or place under water as needed.

Plasma Spraying

• Essential Job Functions:
  • Sets up and operates plasma spray unit.
  • Applies uniform thickness by measuring cores before, during and after plasma spraying.

Setter Production:

• Fabricates and reface setters by pouring slurry into mold cavity; removes binder; fires setters.

Core Repair:

• Essential Job Functions:
  • Inspects cores for surface defects, flash, positives and negatives, and air pockets.
  • Repairs identified defects using established techniques.

Firing:

• Essential Job Functions:
  • Loads and unloads setters and product per PCC specifications.
  • Sets up and operates furnace per instructions.
