Manufacturing Process

OUR PROCESS

At K.R. Manufacturers, each coupling is produced through a carefully controlled process to ensure precision, strength, and lasting performance. Our key manufacturing stages include:

Our-Process-Step-1

Strategic Blueprinting

  • Process: Receive raw material as per purchase specifications.
  • QC Check: Verify material grade, dimensions, surface finish, and test certificate (TC).
Our-Process-Step-2

Raw Material Storage

  • Process: Store approved material in designated area with proper tagging.
  • QC Check: Inspect for correct outer diameter (OD) using Vernier, check for surface damage, and confirm identification tags.
Our-Process-Step-3

Cutting (Automatic Bandsaw)

  • Process: Cut raw bars to required lengths using an automatic bandsaw.
  • QC Check: Verify cut length and ensure edges are free from burrs.
Our-Process-Step-4

Pre-Machining Inspection

  • Process: Inspect cut pieces before machining operations.
  • QC Check: Confirm raw cut piece matches job specifications and drawing requirements.
Our-Process-Step-5

CNC Machining

  • Process: Perform semi-turning, drilling, and other CNC operations.
  • In-Process QC:
    • First-piece inspection
    • Tool wear monitoring
    • Dimensional check using Vernier, Micrometer, & Gauges
Our-Process-Step-6

Intermediate Cleaning & Deburring

  • Process: Remove burrs, chips, and sharp edges after machining.
  • QC Check: Visual inspection to ensure cleanliness and smooth edges.
Our-Process-Step-7

Strategic Blueprinting

  • Process: Perform semi-turning, drilling, and other CNC operations.
  • QC Check:
    • Verify final dimensions as per drawing
    • Length: Vernier Calliper
    • Outer Diameter (OD): Digital micro meter
    • Bore: Bore Gauge / Plug Gauge
Our-Process-Step-8

Secondary Operations

  • Process: Verify thread accuracy, tolerance, and surface finish using standard gauges.
  • QC Check: Visual inspection to ensure cleanliness and smooth edges.
Our-Process-Step-9

Surface Finishing

  • Process: Ensure smooth surface finish and measure coating thickness (hard chrome).
  • QC Check: Visual inspection to ensure cleanliness and smooth edges.
Our-Process-Step-10

Final Dimensional Inspection

  • Process: Conduct complete dimensional verification.
  • QC Check: Perform 100% or sampling inspection using CMM, plug gauges, and other precision instruments.
Our-Process-Step-11

Final QC & Approval

  • Process: Approve product for dispatch after full inspection.
  • QC Check: Visual inspection, dimensional report verification, and QC stamp approval.
Our-Process-Step-12

Packing & Dispatch

  • Process: Pack and label finished products for shipment.
  • QC Check: Inspect packing quality, labelling accuracy, and accompanying documentation.
