Metal parts & components
CNC machining, stamping, casting, extrusions, MIM, laser cutting, punching, welding and fabrication — precision metal components engineered, certified, and delivered on one PO.
Capabilities & Specifications
SureSource manufactures precision metal parts and assemblies using CNC machining, extrusions, stamping, sand and die casting, and welded fabrication, in steel, aluminum, and specialty alloys. We support finishes including powder coating, anodizing, plating, and painted finishes, and hold tolerances to your drawing spec — not “close enough.” We perform in-house DFM review before tooling starts, so cost and manufacturability issues surface before they become schedule and quality risk.
Typical categories include structural brackets and housings, precision-turned and ground components, gears and shafts, springs, fasteners, and welded assemblies for audio, automotive, and industrial equipment applications. We manage certification and compliance documentation (UL, CE, FCC, RoHS, REACH) as part of the production process, and coordinate material certs where traceability matters.
MOQs vary by process and complexity — die casting and stamping typically need higher volumes to be cost-effective than CNC or fabrication. Share your drawing or BOM and we’ll determine the right process and MOQ for your part.
Custom steel brackets, welded steel components, turned steel parts, custom aluminum extrusions, large custom aluminum brackets, welded aluminum components, custom sand case components, aluminum enclosures.
Steel springs, fasteners, handlebars, standard fluid fittings, precision ground gears, high-quality large game fishing hooks.

Frequently Asked Questions
What types of metal parts can SureSource manufacture?
CNC-machined, stamped, cast, extruded, MIM, laser cut, and welded/fabricated components in steel, aluminum, and specialty alloys — from simple brackets to complex multi-part assemblies.
What's the difference between working with a turnkey manufacturer and sourcing metal parts directly from a factory?
A turnkey partner like SureSource owns the full process — supplier selection, tooling, QC, logistics — under one PO and one point of accountability, all in-house. Sourcing direct means managing multiple factories, language and time-zone gaps, and QC yourself. SureSource provides every client a Project Manager who communicates in English and provides updates throughout the entire process.
What tolerances can you hold for CNC-machined or stamped parts?
Tolerances are set by process and material — share your drawing and we’ll confirm achievable tolerances and DFM feedback before quoting.
What's a typical MOQ for custom metal parts?
CNC and fabrication can run small pilot batches; stamping , extruding, and die casting generally need higher volumes to be cost-effective given tooling investment. Send your BOM for a tailored quote.
How do you handle quality control and certification for metal parts shipped internationally?
In-process and outgoing QC checkpoints, with material and process certifications (UL, CE, RoHS, REACH) documented and provided before shipment.
Does SureSource have environmental chambers to test for various environmental conditions?
