Mach Prototype delivers professional custom sheet metal fabrication services, covering prototyping to low‑volume production. We perform laser cutting, bending, stamping and surface finishing for metal components. Strict dimensional tolerance control, multiple material options, fast lead‑time for your sheet metal project.
High‑power laser beams vaporize metal sheets to cut intricate contours and holes, producing high‑precision custom flat blanks for sheet‑metal manufacturing.
Press‑brake machines bend flat metal blanks along set lines to convert flat stock into usable 3D brackets, housings and structural shell components.
Punch‑and‑die tooling shears sheet metal under pressure to create holes and slots, enabling fast, economical high‑volume sheet‑metal part processing.
Forming dies shape sheet metal under press force to mass‑produce uniform, repeatable complex embossed and formed metal parts.
Welding joins individual sheet‑metal pieces, then fastening work combines them to build fully finished, functional ready‑to‑deploy assemblies.
Please consider bending requirements, mechanical performance and corrosion resistance when choosing materials.

Aluminum features low weight, good ductility and excellent bend‑ability. Most grades support complex bending operations. It delivers decent strength and corrosion resistance, widely used for aerospace and automotive sheet‑metal components.
6061, 5052, 5083, 2014
High ductility, outstanding bending & stamping performance. Easy to form intricate bent shapes. Good electrical and thermal conductivity. Best for conductive parts; lower mechanical strength for load‑bearing structures.
C11000 Pure Copper, C101 Oxygen‑Free Copper
Good ductility for moderate bending. Too sharp bends may cause cracking. Nice surface finish, good corrosion resistance. Fit for decorative sheet‑metal parts and electrical hardware.
C3604, C26000, H59, H62
Medium ductility, limited bending capacity. Not recommended for sharp complex bends. High wear resistance and strength, mainly applied for structural wear‑resistant sheet parts.
Good bend‑ability under proper thickness. Harder high‑carbon grades tend to crack during tight bending. High mechanical strength, low cost. Surface rust protection treatment is required.
C45, 1045, A36, Q235
Good ductility for bending, but higher spring‑back effect compared to aluminum. Need to compensate spring‑back value during bending process. Excellent corrosion resistance, high strength, ideal for outdoor & humid‑environment sheet metal assemblies.
304, 316L(1.4404), 303, 430, 17‑4 PH
Retains visible tool marks from CNC cutting. Cost‑effective for non‑visible functional surfaces with no strict cosmetic requirements. Standard surface roughness Ra 1.6‑6.3μm.
An electrolytic conversion coating primarily for aluminum parts. It builds a hard, durable oxide layer to boost wear and corrosion resistance, and supports custom color options.
Mechanical polishing removes surface imperfections to deliver a smooth, high‑gloss surface. It lowers surface roughness and significantly improves the visual quality of metal components.
Pressurized abrasive media strikes the workpiece to form an even, fine matte texture. It eliminates tool scratches and creates an ideal base for subsequent painting or coating.
Parts rotate inside a barrel with abrasive media. This mass‑finishing process removes sharp burrs and softens edges for small‑size workpieces with uniform subtle texture.
An electrochemical smoothing treatment that dissolves tiny surface peaks. It brightens metal surfaces, reduces micro‑roughness and delivers better corrosion performance.
A chemical conversion finish for aluminium substrates. It provides reliable corrosion protection and greatly improves bonding strength for paints and adhesives.
Controlled heating and cooling modifies internal metal microstructure. It precisely adjusts mechanical properties including hardness, tensile strength and material ductility.
Linear unidirectional grinding creates a subtle satin grain texture. This decorative finish hides minor surface flaws and delivers a premium metallic appearance.
A low‑thickness chemical conversion coating for ferrous metals. It creates a matte black finish for anti‑glare purposes and offers moderate corrosion protection.
A thin metallic layer (nickel, chrome, zinc etc.) is chemically deposited on component surfaces. It enhances hardness, anti‑corrosion performance and surface conductivity.
We maintain precise dimensional tolerances and controlled surface roughness for custom sheet‑metal parts in compliance with ISO 2768 standards.
We offer large‑size laser cutting and bending capacities, with multiple surface finish options from as‑machined to brushed and polished. See the table for full technical specifications.

Sheet‑metal fabrication transforms flat thin metal sheets into finished parts via cutting, bending and secondary operations. It is ideal for prototype and low‑volume projects, supporting aluminum, steel, stainless steel and other metals for housings, brackets and assemblies.
Your CAD drawing drives laser cutting or punching to produce flat blanks. Press brakes bend blanks into target geometries. Additional tapping, welding and surface treatments complete your custom sheet‑metal components.
Good Structural Strength
Sheet metal parts deliver high strength‑to‑weight ratio. Thin metal sheets create rigid, durable housings and frames for mechanical and electronic equipment.
Wide Material Selection
Compatible with aluminum, mild steel, stainless steel, copper and brass sheets. Different grades and thicknesses satisfy strength, anti‑corrosion and weight‑reduction requirements.
Versatile Surface Treatments
Raw laser‑cut surfaces are clean. A full set of finishing options including powder coating, anodizing, plating and brushing for protection and cosmetic appearance.
Flexible Part Geometry
Supports various bent, punched and welded structures from simple panels to complex enclosures. Easily realize custom shapes directly from your CAD files.
Cost‑Effective for Prototypes & Small Batches
No expensive stamping molds are needed. It works well for proof‑of‑concept prototypes and low‑volume custom production to save your tooling investment.
Reliable Batch Consistency
