MHAOCNC provides integrated stainless steel sheet metal fabrication from raw sheet to finished assembly.
Our main capabilities include:
Laser cutting
CNC bending
TIG welding
MIG welding
Riveting
Tapping
Grinding
Brushing
Polishing
Passivation
Powder coating
Painting
Component assembly
By combining multiple processes in one manufacturing workflow, we can reduce unnecessary handling between suppliers and improve dimensional consistency throughout production.
Depending on the part design, the typical process can include:
Drawing Review → Laser Cutting → CNC Bending → Welding → Grinding → Brushing or Polishing → Passivation → Inspection → Assembly
CNC bending is used to create flanges, angles, channels, brackets, housings, frames, and other formed sheet metal structures.
MHAOCNC supports a typical bending tolerance of ±0.2 mm and angular accuracy of ±0.5°.
For selected precision features, positional accuracy can reach ±0.15 mm, depending on material thickness, bend radius, geometry, and overall part configuration.
Typical bent stainless steel parts include:
Mounting brackets
Equipment panels
Enclosure bodies
Structural frames
Covers
Trays
Support plates
Control cabinet components
For projects focused mainly on forming operations, our dedicated sheet metal bending services can support additional bending requirements.
Welding is one of the key capabilities of this product line.
MHAOCNC provides both TIG welding and MIG welding for custom stainless steel sheet metal components.
TIG welding is suitable for stainless steel parts requiring controlled heat input, clean weld appearance, and precise joining.
It is commonly used for:
Stainless steel enclosures
Thin sheet metal components
Visible welded structures
Precision frames
Food equipment parts
Instrument housings
MIG welding is suitable for structural components and production parts requiring efficient and stable welding.
Typical applications include:
Equipment frames
Structural supports
Industrial housings
Brackets
Welded assemblies
Weld strength can reach ≥200 MPa according to the specified material, joint design, and welding requirements.
After welding, the joint area can be ground, blended, brushed, or polished according to the required surface appearance.
Brushed stainless steel is widely used for parts requiring a clean, uniform, and industrial surface appearance.
MHAOCNC can provide brushed finishes for stainless steel 304, 316, and other specified grades.
Available finishing work can include:
Directional brushing
Weld seam grinding
Surface blending
Polishing
Passivation
Surface appearance matching
For welded assemblies, the weld area can be ground and re-brushed to match the surrounding grain direction and surface appearance.
This is especially important for:
Equipment enclosures
Machine covers
Control panels
Food processing equipment
Commercial stainless steel products
Visible industrial components
Brushed surface roughness can be controlled according to project requirements, including Ra 0.8–1.6 μm where specified.
Passivation can be applied to stainless steel components after cutting, bending, welding, and finishing.
Where required, passivation can be performed according to ASTM A967 requirements.
Passivation helps remove free iron and surface contamination while supporting the natural corrosion resistance of stainless steel.
For selected stainless steel parts with specified finishing and test conditions, salt spray performance can reach ≥1,000 hours.
Other finishing options include:
Polishing
Electroplating
Powder coating
Painting
Custom surface finishing
The final surface treatment should be selected according to the material, environment, appearance, and corrosion resistance requirements of the project.
MHAOCNC produces a wide range of custom stainless steel welded and bent components.
Typical parts include:
Stainless steel enclosures
Equipment housings
Welded frames
Machine covers
Control panels
Mounting brackets
Support structures
Stainless steel trays
Equipment panels
Cabinet components
Instrument housings
Food equipment parts
Structural assemblies
Custom fabricated components
Each part can be manufactured according to customer-supplied 2D drawings, 3D models, samples, or technical specifications.
Custom stainless steel welded sheet metal parts are widely used in equipment and structures that require strength, corrosion resistance, and clean surface appearance.
Typical applications include machine covers, frames, brackets, control cabinets, equipment panels, and structural assemblies.
Stainless steel is widely used in food processing environments because of its corrosion resistance and cleanable surface.
Typical parts include trays, housings, covers, supports, and welded assemblies.
Custom stainless steel sheet metal parts can be manufactured for medical equipment and instruments according to customer drawings, material specifications, tolerance requirements, and inspection criteria.
Brushed stainless steel components can be used for visible panels, housings, frames, decorative structures, and commercial equipment.
Stainless steel 316 and suitable surface treatments can be selected for components used in environments requiring improved corrosion resistance.
Quality inspection is performed according to customer drawings and project requirements.
Inspection can include:
Dimensional inspection
Bending angle inspection
Weld appearance inspection
Surface finish inspection
Assembly verification
