What Custom Sheet Metal Fabrication Services Does XC Machining Offer?
XC Machining provides custom sheet metal fabrication for enclosures, brackets, panels, chassis, frames, housings, and covers in steel, stainless steel, aluminum, copper, and brass. We handle single prototypes through 10,000+ production runs from our Dongguan, China facility.
One of the custom sheet metal parts suppliers, XC Machining, has been producing highly accurate custom sheet metal parts that are used in many areas of settings. We have state of art equipment that is used to manufacture parts to your desired design specifications.
Our sheet metal department operates fiber laser cutters (up to 6kW), CNC press brakes (up to 250 tons), TIG and MIG welding stations, CNC turret punch presses, and roll forming equipment. All fabrication follows ISO 9001:2015 quality procedures.
How Fast Can XC Machining Deliver Sheet Metal Prototypes and Production?
XC Machining delivers sheet metal prototypes in 3–5 business days and production batches in 7–15 days. Prototype orders of 1–100 parts use the same laser cutting, bending, and welding processes as production, ensuring your prototype is dimensionally identical to the final manufactured part.
Production volumes scale from single prototypes through 50,000+ annual parts. CNC press brake bending, laser cutting, and welding processes maintain ±0.1 mm consistency across prototype and production runs — no compromise between batch sizes.
XC Machining operates sheet metal fabrication from our facility in Dongguan, China, serving customers in the USA, Europe, and Asia with DHL/FedEx/UPS international shipping and full export documentation.
What Makes XC Machining Different for Sheet Metal Fabrication Projects?
XC Machining sheet metal fabrication combines fiber laser cutting (6kW), CNC press brakes (250 tons), certified TIG/MIG welding, and ISO 9001:2015 quality across all operations from prototype through high-volume production.

What Surface Finishes Are Available for Sheet Metal Fabricated Parts?
XC Machining applies the following surface finishes to sheet metal fabricated parts for corrosion protection, wear resistance, cosmetic appearance, and regulatory compliance.
Powder coating applies a 60–120 μm thermoset polymer layer to steel and aluminum sheet metal parts with RAL/Pantone color matching and UV resistance. Available in gloss, semi-gloss, matte, and textured finishes.
Anodizing (Type II standard, Type III hard-coat to 80 μm) protects aluminum sheet metal parts with custom color options and Rockwell hardness up to 70. Minimum 0.5 mm sheet thickness required for anodizing.
Brushing creates a directional satin grain at Ra 0.4–0.8 μm on stainless steel and aluminum sheet metal, masking minor scratches and providing a professional industrial appearance for enclosures and panels.
Mirror polishing achieves Ra 0.05–0.2 μm on stainless steel and aluminum sheet metal parts for decorative panels, hospitality fixtures, and architectural trim requiring high-gloss reflective surfaces.
Zinc electroplating deposits a 5–25 μm zinc layer on mild steel and carbon steel sheet metal for 200–500 hour salt spray corrosion resistance per ASTM B117 testing. Clear or yellow chromate passivation available.
Hot-dip galvanizing deposits 45–85 μm zinc coating on steel sheet metal for outdoor and industrial applications requiring 1,000+ hour salt spray resistance. Ideal for structural brackets, frames, and enclosures exposed to weather.

Frequently Asked Questions
What Is Sheet Metal Fabrication and What Parts Can It Produce?
Sheet metal fabrication transforms flat metal sheets (0.5–12 mm thickness) into finished parts through laser cutting, CNC bending, welding, punching, and forming. Common sheet metal parts include enclosures, brackets, panels, chassis, frames, covers, heat shields, and ductwork. XC Machining fabricates sheet metal in steel, stainless steel, aluminum, copper, brass, and titanium for automotive, electronics, medical, telecom, and industrial applications.
What Metals Does XC Machining Fabricate in Sheet Metal?
XC Machining fabricates: mild steel A36/1018 (general purpose), stainless steel 304/316/430 (corrosion-resistant), aluminum 5052/6061 (lightweight), copper C110 (electrical/thermal conductivity), brass C260/C360 (decorative/conductive), galvanized steel (pre-coated corrosion protection), cold rolled steel CRS 1008/1010 (precision enclosures), hot rolled steel A36/1011 (structural), and titanium Grade 2/5 (aerospace/medical). Sheet thickness: 0.5–12 mm across all materials.
What Tolerances Does XC Machining Achieve in Sheet Metal Fabrication?
XC Machining holds ±0.1 mm on laser-cut features (fiber laser, ±0.05 mm capable), ±0.1° on CNC press brake bends (CNC back gauge positioning), and ±0.5 mm on welded assemblies (jigged TIG/MIG). Punched hole positions are accurate to ±0.1 mm. All tolerances are per ISO 2768-m unless tighter specifications are noted on your drawing. CMM inspection verifies critical dimensions on every first article.
What Is the Lead Time for Sheet Metal Fabrication at XC Machining?
Sheet metal lead times at XC Machining: simple laser-cut flat parts — 2–3 business days, standard formed parts (cut + bend) — 3–5 days, welded assemblies — 5–7 days, complex multi-operation parts with hardware and finishing — 7–15 days. Rush delivery available for time-critical projects. Production batches of 1,000+ parts typically require 10–20 business days depending on finishing requirements.
What Post-Processing and Finishing Options Are Available for Sheet Metal Parts?
XC Machining post-processing for sheet metal: deburring (tumble, manual, or thermal), powder coating (60–120 μm, RAL color matching), anodizing (Type II/III for aluminum), zinc plating (5–25 μm), galvanizing, brushing (Ra 0.4–0.8 μm), polishing (Ra 0.05–0.2 μm), painting (primer + topcoat), silk screening, hardware insertion (PEM studs, clinch nuts, standoffs), and electrostatic painting for complex geometries.
