Precision Sheet Metal Fabrication

Custom Precision Sheet Metal Components

High-Quality Sheet Metal Parts with Tight Tolerances

Our precision sheet metal fabrication service delivers accurate, durable, and cost-effective sheet metal components. From prototype development to mass production, we support OEMs with custom enclosures, panels, brackets, chassis, and complex formed parts.

Service Overview

What Is Precision Sheet Metal Fabrication?

Sheet metal fabrication transforms flat metal sheets into functional parts and assemblies through cutting, punching, bending, forming, welding, and surface finishing. Precision sheet metal fabrication focuses on tight tolerances, consistent bend angles, clean edges, and reliable repeatability — essential for enclosures, panels, brackets, and machine housings.
At Golift, we process customer CAD files (DXF, DWG, STEP) and use nesting software to maximize material utilization, reduce waste, and lower part cost.

CAD File Review

Validate DXF/DWG/STEP files and check bend allowances.

Nesting

Arrange parts on sheet metal to maximize material usage.

Cutting / Punching

Laser cut or punch holes, slots, and outer profiles.

Deburring

Remove sharp edges and burrs for safe handling and quality finish.

Bending / Forming

CNC press brake forms flanges, channels, boxes, and brackets.

Welding / Assembly

Join multiple parts; install hardware, hinges, or fasteners.

Surface Finishing

Powder coat, anodize, paint, or polish to final specification.

Final Inspection

Dimensional and visual check before packaging.

Quality Control

Quality Control for Sheet Metal Parts

Four inspection gates stand between raw material and export packaging. Every part is checked at each stage — nothing ships until it passes them all.

Step 01

First Article Inspection (FAI)

Every new design starts with a full first-article dimensional review before batch production is released.
Step 01
Step 02

In-Process Dimensional Checks

Dimensions are checked after each critical operation — catching deviations while they can still be corrected.
Step 02
Step 03

Bend Angle Verification

Bend angles are verified against your drawing using precision gauges or CMM — every time, not just at setup.
Step 03
Step 04

Surface & Coating Inspection

Surface finish quality and coating thickness are inspected to match your specification — color, gloss, and coverage.
Step 04
Step 05

Final Assembly Fit Check

Complete assemblies are fit-checked before shipment, so the parts you receive go straight into your production line.
