End-to-End Process
From Flat Sheet to Finished Assembly — One Partner.
Amsol's sheet metal capability covers the complete manufacturing chain — cutting, stamping, forming, welding, and finishing — under one quality system. No transfer between separate suppliers. No dimension loss at each handover. One inspection report covering the complete fabrication.
Process 01 — Cutting
Laser Cutting & CNC Punch
⚡ Laser Cutting & CNC Punch
±0.1mm. Any Profile. Any Hole Pattern.
Laser cutting produces any 2D profile from flat sheet with ±0.1mm accuracy — no tooling cost, no setup time per profile, no minimum order. CNC punching for repetitive hole patterns, louvres, and knockouts in high-volume production. Both processes work on mild steel, stainless, aluminium, and galvanised sheet from 0.5mm to 25mm thickness.

Stamping — High Volume. Precise. Low Cost Per Part.
Progressive die stamping and blanking for high-volume sheet metal components. Where laser cutting is flexible, stamping is fast and economical at volume — the same part produced thousands of times per hour with no per-part processing cost. Amsol's stamping capability covers blanking, piercing, drawing, embossing, and coining from mild steel, stainless, aluminium, and copper strip.
Process 02 — Stamping
Progressive Die Stamping & Blanking
🔨 Progressive Die Stamping
Blanking. Piercing. Drawing. Embossing. Volume from 5,000/year.
Progressive die stamping feeds strip material through a series of die stations — each station adds one forming operation — until the finished component exits at the end. One press stroke produces one complete part. At volumes from 5,000 per year, stamping delivers the lowest cost-per-part of any sheet metal process. Amsol's stamping covers blanking (cut to shape), piercing (holes), drawing (3D forms), embossing (raised features), and coining (precision thickness).

Process 03 — Forming
CNC Press Brake Bending & Roll Forming
📐 Bending & Roll Forming
±0.5° Angular Accuracy. Complex Multi-Bend Profiles.
CNC press brake bending converts flat laser-cut blanks and stamped parts into 3D forms — brackets, enclosures, channels, frames, and structural sections. CNC back gauge ensures ±0.5° angular accuracy on every bend. Roll forming for cylindrical and conical profiles — tanks, pipes, curved enclosures. Multi-stage bending for complex profiles with 4+ bends programmed and verified on first article before production.

AWS D1.1. Coded Welders. Full Weld Inspection.
Welding is where sheet metal parts become assemblies — and where quality discipline matters most. Amsol's welding operation covers MIG (GMAW) for structural and high-production fabrications, TIG (GTAW) for precision stainless and aluminium welding, spot welding for thin-sheet automotive-style assemblies, and structural welding to AWS D1.1. All welders are qualified. Weld quality verified by visual inspection, dimensional check, and NDT where specified.

Weld Quality & Inspection
Six Weld Quality Standards Amsol Maintains
A perfectly cut and bent bracket becomes useless if the weld is inconsistent, under-penetrated, or distorted. Amsol's welding quality system covers every joint on every assembly.
AWS D1.1 Structural
Structural welding to American Welding Society D1.1. Pre-qualified joint details. Procedure qualification records maintained. Applicable to all structural steel fabrications.
Qualified Welders
All Amsol welders qualified to relevant welding procedure specifications. Qualification records maintained. Welder performance tracked per process and material.
Visual Inspection (VT)
100% visual inspection on all welds. Bead profile, size, length, undercut, overlap, and surface porosity checked against drawing specification before assembly moves to next stage.
Dimensional After Weld
Critical dimensions re-verified after welding by CMM or checking fixture. Welding distortion controlled by fixture and sequence — not corrected after the fact.
NDT — PT / UT on Request
Penetrant testing (PT) for surface defects on stainless and aluminium welds. Ultrasonic testing (UT) for internal soundness on structural welds where specified. Both available on request.
Pressure Test Available
Hydrostatic and pneumatic pressure testing for welded vessels, tanks, and pressure-containing fabrications. Test pressure to customer specification. Certificate issued.
