CNC Machining Precision Components | Custom Manufacturing
Mechpart delivers high-precision CNC turned and milled components engineered to the most demanding tolerances in the industry. Our ISO-certified facility handles everything from one-off prototypes to full-scale production runs of 100,000+ units, working across aluminum alloys (6061, 7075), stainless steel (304, 316L), titanium (Ti-6Al-4V), brass, and engineering plastics. Every component undergoes in-process inspection with CMM verification traceable to international standards, ensuring dimensional accuracy down to ±0.005mm and surface finishes as fine as Ra 0.4μm. Our CNC precision parts serve mission-critical applications across aerospace (engine brackets, actuator housings, landing gear components), medical devices (surgical instrument bodies, implant fixtures, diagnostic equipment chassis), automotive (EV powertrain spacers, sensor mounts, valve bodies), and robotics (joint assemblies, end-effector mounts, drivetrain components). We routinely produce complex geometries including undercuts, deep-hole drilling, multi-axis contours, and tight-tolerance threading that many shops decline—backed by full material certifications and PPAP documentation when required. Why do procurement managers in 12+ countries choose Mechpart? Because we combine 15 years of CNC expertise with a transparent, engineer-to-engineer workflow: you upload a 3D file (STEP/IGS/X_T), receive a DFM review within 24 hours, and track your order through our online portal from blank to finished part. No hidden surcharges, no minimum-order games—just precision machining backed by an on-time delivery rate of 98.6%.

Custom Industrial Fasteners & Bolts | Precision Manufacturing
Mechpart manufactures standard and custom-engineered fasteners that meet the exact specifications of your assembly line, construction project, or heavy-equipment overhaul. Our portfolio spans metric (M3–M64) and imperial (UNC/UNF) threads in strength grades from 8.8 through 12.9 for carbon/alloy steel and A2/A4 for stainless steel, with optional coatings including zinc plating, hot-dip galvanizing, Dacromet, and Xylan. Every batch is traceable to its heat lot with full mechanical-property test reports (tensile, yield, elongation, hardness) available on request. Our fasteners are deployed in structural steel frameworks, automotive powertrain assemblies, wind-turbine flange connections, railway infrastructure, and marine deck hardware—environments where a failed bolt means downtime measured in thousands of dollars per hour. We supply OEMs requiring just-in-time delivery schedules as well as MRO buyers who need mixed kits of unusual thread pitches, captive washers, or tamper-proof drive geometries shipped within a week. What sets Mechpart apart from catalog distributors? We don't just pick parts from a warehouse—we engineer solutions. Need a custom shoulder bolt with an under-head radius to eliminate a stress riser? A titanium hex-cap screw for a weight-sensitive aerospace fixture? A nylon-patch locking fastener that survives 500 thermal cycles? Our in-house tooling department turns drawings into finished parts faster than most competitors can process a purchase order. Standard fasteners ship in 1–3 weeks; custom designs in 3–5. Minimum order quantities start at 1,000 pieces for stock items and scale down for specials—talk to our team.
Metal Casting Service | Custom Cast Parts Manufacturing
From single prototypes to 50,000-unit production runs, Mechpart's casting division delivers ferrous and non-ferrous cast parts through sand casting, investment casting (lost-wax), and high-pressure die casting processes. Our foundry partners handle part weights from 0.5 kg to 500 kg in materials including gray iron, ductile iron, carbon steel, stainless steel (304/316/2205), aluminum alloys (A356, ADC12), and copper-based alloys (brass, bronze). Dimensional tolerances as tight as ±0.1mm are achievable depending on the process, with comprehensive NDT inspection (X-ray, dye penetrant, ultrasonic) available for safety-critical components. Industries served include pump and valve manufacturing (impellers, bodies, bonnets), agricultural machinery (hitch components, gearbox housings), construction equipment (bucket teeth, track idlers, boom pivots), and marine propulsion (propellers, struts, rudder stocks). We routinely cast parts with complex internal passages, thin-walled sections down to 3mm, and surface finish requirements that eliminate secondary machining operations—reducing your total landed cost. Why choose Mechpart for casting? Because we bridge the gap between low-cost offshore foundries that ship to a PO box and premium domestic shops with year-long backlogs. Every casting project includes a solidification simulation review, a first-article inspection report with dimensional layout, and a metallurgical certificate per heat. Lead times run 3–6 weeks from pattern approval to shipment, with expedited options for urgent tooling. Cast your next project with a partner who treats quality as a process, not a promise.
Sheet Metal Stamping Parts | Custom Fabrication & Assembly
Mechpart provides progressive-die and transfer-die stamping solutions for sheet metal components ranging from simple brackets to complex multi-bend enclosures. Our press capacity spans 1 ton to 400 tons, processing cold-rolled steel, stainless steel (301/304/316), aluminum (5052/6061), copper, and pre-plated materials in thicknesses from 0.5mm to 6mm. Each stamping line is supported by in-house wire-EDM tooling, CMM first-article inspection, and automated vision sorting for zero-defect deliveries on safety-critical parts. Typical applications include automotive body-in-white brackets and reinforcement plates, electrical enclosure chassis and busbar connectors, HVAC duct flanges and mounting frames, consumer appliance structural panels, and solar-energy mounting hardware. We excel at rapid tooling for new-product introduction (NPI) programs, delivering prototype stampings in as little as two weeks before transitioning to hardened production tooling for volumes exceeding one million strokes per year. What makes Mechpart a preferred stamping partner? Our tooling engineers review every part drawing for manufacturability before cutting steel—catching burr-direction issues, springback compensation needs, and strip-layout inefficiencies that inflate your per-piece cost. Combined with an in-house secondary-operations cell (tapping, welding, riveting, assembly), we deliver finished subassemblies, not just blanks. Standard lead time is 2–4 weeks with MOQs from 500 pieces; contact us for full-service stamping that treats your budget as carefully as your tolerances.
Forged Components & Parts | Industrial Hot & Cold Forging
Mechpart produces hot-forged and cold-forged components that deliver the grain-flow integrity and fatigue resistance demanded by heavy-industry applications. Our forging capabilities cover part weights from 0.1 kg to 50 kg in carbon steel (1045, 4140), alloy steel (4340, 8620), stainless steel (304, 316, 17-4PH), and aluminum alloys, with secondary heat-treatment options including quench-and-temper, normalizing, annealing, and induction hardening. Closed-die, open-die, and upset forging processes are available, supported by in-house die design and CNC finish machining for net-shape delivery. End-use segments include automotive driveline (connecting rods, steering knuckles, axle shafts), heavy machinery (track links, bucket pins, ripper shanks), oil-and-gas (flanges, valve bodies, pup joints rated to API 6A), and power generation (turbine blade preforms, generator shaft couplings). Components are routinely tested to ASTM, ASME, and customer-specific standards with full mill-cert traceability included as standard—not as a line-item surcharge. Why forge with Mechpart? Three words: reliability at scale. Our forging supply chain is vertically integrated from billet procurement through finish machining, eliminating the finger-pointing that plagues multi-vendor projects. Every shipment includes a dimensional inspection report, material certification, and surface-quality documentation. Lead times of 3–5 weeks from die approval, with MOQs as low as 100 pieces for development programs. Forge ahead with a partner that understands the difference between a casting and a forging—and when your application demands the latter.
Plastic Injection Molding Parts | Custom Manufacturing Service
Mechpart offers end-to-end custom plastic injection molding from 50-ton to 1,000-ton clamp force, capable of producing parts from a few grams to 5 kg in shot weight. Our material palette includes engineering thermoplastics (ABS, PC, PA6/PA66, POM, PBT, PPS, PEEK), commodity resins (PP, PE, PS, PVC), and glass-fiber-reinforced grades for structural applications. Mold-flow analysis and in-house tooling design ensure that every mold is optimized for cycle time, part quality, and mold longevity before the first steel chip is cut. Our injection-molded parts appear in medical-device housings (ISO 13485 clean-room molding available), automotive interior and under-hood components, consumer electronics enclosures, industrial control-panel bezels, and packaging components. We support overmolding, insert molding, two-shot molding, and gas-assist processes for complex multi-material designs that reduce assembly cost and improve product reliability. Why Mechpart for injection molding? Because we treat molding as an engineering discipline, not a commodity. Our tooling engineers provide a free DFM report within 48 hours of receiving your 3D CAD, identifying wall-thickness issues, sink-mark risks, draft-angle deficiencies, and gate-location optimizations before you spend a dollar. Standard lead time is 3–5 weeks for mold build and sampling, with production MOQs from 500 pieces. PPAP Level 3 documentation, Cpk studies, and IMDS submissions are handled in-house—making us a turnkey supplier for automotive and medical OEMs who can't afford a paperwork bottleneck.
Surface Treatment & Finishing Services | Industrial Coating Solutions
Mechpart delivers a complete suite of surface treatment and finishing services engineered to enhance corrosion resistance, wear performance, aesthetic quality, and electrical conductivity of your manufactured parts. Our in-house and partnered finishing lines cover anodizing (Type II sulfuric, Type III hardcoat in colors including clear, black, red, and blue), electroplating (zinc with trivalent Cr3+ passivation, nickel, hard chrome, electroless nickel), powder coating (epoxy, polyester, hybrid formulations with RAL color matching), and conversion coatings (Alodine, phosphate). Every finish is processed to RoHS and REACH compliance with full certification provided. Our surface-treatment expertise extends across aerospace (MIL-spec anodizing and passivation), automotive (corrosion-resistant underbody brackets and aesthetic trim pieces), medical-device housings (biocompatible electropolishing), consumer electronics (conductive chromate coatings on aluminum heatsinks), and architectural fittings (weather-resistant powder-coated railings and cladding). We handle parts ranging from M2 fasteners to 3-meter structural extrusions, with rack and barrel processing available to optimize cost for your batch size. Why outsource surface treatment to Mechpart? Because we eliminate the logistics headache of splitting manufacturing across three vendors. Send us your machined, cast, stamped, or forged parts—they return to you fully finished, inspected, and sealed for shipment under one purchase order and one quality system. Standard lead time is 1–2 weeks with expedited 72-hour turnaround available. MOQs start at one lot; volume pricing scales transparently. Finish strong with a partner who treats the last micron of coating as carefully as the first.
