GN Corporations Inc.

Automated Machining
GN is the largest private machining facility in western Canada featuring over 65 CNC machine tools, 25% of our CNC machine tools are fully automated. That is, robots are load/unload, deburr, part mark and measure all components produced. Virtually all of our CNC machine tools are multi-tasking that are capable of machining all components complete in one chucking. We also have a conventional machine shop that allows to perform specialized machining operations and tooling and fixturing for our production CNC machine tools.

Induction Hardening
Induction hardening is a form of heat treatment in which a metal part is heated by induction heating and then quenched. The quenched metal undergoes a martensitic transformation, increasing the hardness and brittleness of the part. Localized hardening of Cast Iron and Steel of different diameters and different shapes, includes tempering, micro hardness testing and microscopic testing.

Zinc Phosphate
· Zinc Phosphate per MIL-DTL-16232G, Type Z, Class 1. Follow with oil. – Coating Weight 1000 to 1800 mg/ft2 Salt Spray Test as per ASTM B117
· Zinc Phosphate per MIL-DTL-16232G, Type Z, Class 3. – Coating Weight 1000 to 1800 mg/ft2
· Zinc Phosphate per MIL-DTL-16232G, Type Z, Class 1. Follow with oil. – Coating Weight 150 to 500 mg/ft2 Salt Spray Test as per ASTM B117
· Zinc Phosphate per MIL-DTL-16232G, Type Z Class 3. – Coating Weight 150 to 500 mg/ft2

Fluoropolymer Coating
These coatings are a superior dry film lubricant that produce a smooth, hard, slick coating and provide excellent corrosion and chemical resistance. Other benefits of fluoropolymer coatings include reduced friction, resistance to galling, non-stick, non-wetting, electrical resistance and abrasion resistance. Dupont Teflon-S 959G-203 is used and Whitford products will be used for Xylan coating.

NDT (MPI/LPI)
MPI is used for the detection and sizing (length not depth) of surface-breaking cracks in ferromagnetic materials and LPI is used for same but non-ferrous material.

GN is equipped with Magnetic Particle Inspection (MPI) machines and Liquid Penetrant Inspection (LPI) line and Inspectors are certified through Canadian General Standards Board (CGSB Level II). Both LPI and MPI is set up for high volumes as well as large pieces with any shape (Yoke AC/DC will be used). And Latest editions of ASTM E-1444, ATM E-709, ESTM E1316, ASTM E-1417, ASTM E-1316 and ASTM E-1209 are followed.
