FAQ
What is your minimum order quantity for custom metal components?
Our minimum order quantity varies depending on the complexity of the component. For simple stamping parts, we can accept orders as low as 100 pieces, while more complex CNC machined components typically have a minimum of 50-100 pieces. We also offer prototyping services without minimum quantity requirements for design validation.
How do you ensure the dimensional accuracy of custom components?
We maintain dimensional accuracy through several measures: 1) Using high-precision CNC equipment with ±0.005mm positioning accuracy; 2) Implementing regular machine calibration and maintenance; 3) Conducting in-process inspections with CMM (Coordinate Measuring Machine); 4) Performing final dimensional checks before shipping. All measurements are documented in our quality control reports.
What materials can you work with for custom metal parts?
Our material capabilities include: 1) Ferrous metals: Cold-rolled steel, stainless steel (304, 316, etc.), spring steel; 2) Non-ferrous metals: Aluminum alloy (6061, 7075), brass, copper, bronze; 3) Special materials: Titanium, nickel alloys, beryllium copper upon request. We source materials from certified suppliers and provide material certificates with each shipment.
How long does it typically take to produce custom metal components?
Production lead times depend on component complexity and order quantity: 1) Prototyping: 5-15 days for simple parts, 2-4 weeks for complex components; 2) Mass production: 2-4 weeks for stamping parts (10,000+ pieces), 3-6 weeks for CNC machined components (1,000+ pieces). We provide detailed production schedules at order confirmation and maintain regular communication about progress.
What surface treatments are available for metal components?
We offer comprehensive surface treatment options: 1) Electroplating: Zinc, nickel, chrome, tin, silver, gold plating; 2) Anodizing: Clear, black, or colored anodizing for aluminum; 3) Painting: Powder coating, wet painting in various colors; 4) Other treatments: Passivation, blackening, brushing, polishing, sandblasting. Our engineers can recommend the most suitable surface treatment based on your application requirements.
