Mechanical Assembly FAQ
What is mechanical assembly?
Mechanical assembly is the process of joining individual components—such as machined parts, stamped parts, fasteners, bearings, and electronic elements—into a complete functional unit. This can include manual, automated, or semi‑automated processes.
What tolerances can mechanical assemblies meet?
Tolerances typically include ±0.01–0.05 mm for CNC machined parts, ±0.05–0.1 mm for stamped parts, and ±0.1–0.3 mm for molded parts, depending on complexity and application requirements.
How much does mechanical assembly cost?
Cost depends on component complexity, volume, labor, testing, and supply chain requirements. Simple assemblies may cost a few dollars, while complex assemblies can cost significantly more. Meco provides detailed DFM costing support.
What is included in a full mechanical assembly service?
Services include component fabrication, sourcing, sub‑assemblies, fastener installation, bonding, alignment, testing, packaging, and supply chain coordination.
