Quality

Quality Defines Our Culture and Our Processes

In the absence of standards the term quality can become ambiguous, often used more in marketing than procedure. At Hapman quality is both engrained in our processes and integrated into our culture.

The term quality by definition is what drives our entire operating environment. Our engineering, operations, and production system is a balance of three key elements;

  1. Philosophy: Our blueprint for success
    • Customers First
    • People are the most valuable resource
    • Kaizen is our way of life, the way we complete
    • Shop floor focus
  2. True North: Pointing toward perfection
    • Customer Satisfaction
      • ZERO Defects
      • 100% Value Added
      • Build only what is needed to meet demand
    • Human Development
      • Physical Safety & Security
      • Professional Challenge
      • Mental Growth & Contribution
  3. Technical Tools: The tools of the Production System
  4. Practicing Compliance Standards

Stainless Steel Finishes

Standard Finish

Stainless Steel standard welding finish sample.Surface Finish Specification

  • All metal surfaces to have primary mill finish as rolled, drawn or formed
  • Edges deburred

 

 

 

Weld Finish Specification

  • Free of splatter
  • Free of discoloration (stainless steel surfaces)
  • Light clean up and wire brush
  • The weld when finished is not necessarily flush, ripple or crevice free

Food Grade Finish

Surface Finish Specification:

  • Sheet metal (to 10 ga.) to have 2B mill finish and free of scratches and cracks
  • All other metal surfaces (i.e. plate, structural, machined, cast, etc.) to be polished to a 120 grit finish and all scratches removed. Pull clamps, bolts, nuts, roll pins, keys, etc. not polished
  • Grain direction to be indiscriminate
  • Edges deburred

Weld Finish Specification:

  • Welds continuous unless otherwise noted
  • Free of cracks, spatter and discoloration
  • Weld ground with 120 grit abrasive to smooth entire weld and is crevice free
  • Weld is not necessarily ripple free, flush or blended with base metal surrounding the weld

Sanitary Finish

Stainless Steel sanitary welding finish sample.Surface Finish Specification:

  • All metal surfaces polished to a 150 grit finish and all scratches removed
  • Pull clamps, bolts, nuts, roll pins, keys, etc. not polished
  • Grain direction to be indiscriminate
  • Edges deburred

Weld Finish Specification:

  • Welds continuous unless otherwise noted
  • Free of cracks, spatter, ripple and discoloration
  • Weld ground with 150 grit abrasive to smooth entire weld and is crevice free
  • Weld when finished will contain no bead left around the weld and will be flush and blended with base metal surrounding the weld. In corners the weld will be radiused and blended into base metal.
