FAQ of precision machining manufacturer
What manufacturing services do you offer? Can you deliver end-to-end?
Weldo Machining supports CNC machining, sheet metal fabrication, aluminum extrusion, 3D printing, and tooling/mold development. From prototypes to low-volume and mass production, we match the best process plan based on geometry, cost, and lead time for one-stop delivery.
What CNC tolerances can you achieve, and how are tolerances handled?
Standard parts follow typical default tolerances of 0.01–0.05 mm. For high-precision fit components, tolerances can reach ±0.003 mm (depending on part design and material). We recommend specifying GD&T, critical dimensions, datums, and surface finish on the drawing for consistent results.
What are your typical lead times for prototypes and production? Do you offer expedited shipping?
Lead time depends on process, quantity, material availability, and secondary operations such as heat treatment or finishing. Prototypes can be evaluated for rush builds; low-volume and production runs are confirmed with scheduling. Expedited options include priority scheduling, split shipments, and staged deliveries.
What materials can you machine, and can you help with material selection?
We work with aluminum alloys, stainless steels, carbon/alloy steels, copper/brass, and engineering plastics. We can also recommend material substitutions for performance or cost, and support finishing such as anodizing, plating, powder coating, and sandblasting.
What files do you need for a quote, and how do you ensure quality consistency?
Please provide 3D files (STEP/IGES, STEP preferred) and 2D drawings (PDF/DWG) with tolerances, finish requirements, quantity, and revision. We support critical-dimension inspection and process controls, and can provide inspection records upon request to ensure consistency from prototype to production.
