FAQ
What is your minimum order quantity for custom metal parts?
Our minimum order quantity depends on the complexity of the part and production process. For simple stamping parts, we can accept orders as low as 100 pieces for initial production runs. More complex CNC machined components typically have a minimum order of 50-100 pieces. We understand that new product development often requires smaller quantities for testing, and we’re flexible to support our clients’ needs during these stages.
How do you ensure the dimensional accuracy of custom components?
Dimensional accuracy is maintained through several measures: First, our engineering team reviews all drawings carefully before production. Second, we use high-precision equipment with automatic feeding systems to minimize human error. Third, we implement in-process inspection using calipers, micrometers, and CMM machines. Finally, for critical dimensions, we perform 100% inspection before shipping. Our quality system documents all measurement data for traceability.
What materials can you work with for custom metal parts?
We have extensive experience working with various metals including stainless steel (304, 316), carbon steel (Q235, Q345), aluminum alloys (6061, 7075), brass (H59, H62), and copper. For each material, we can recommend suitable surface treatments based on the application environment. For example, stainless steel parts can be passivated for enhanced corrosion resistance, while carbon steel parts typically receive zinc plating or powder coating.
How long does it take to produce custom metal components?
Production lead time depends on several factors: part complexity, order quantity, and our current production schedule. For simple stamping parts, sample production takes about 7-10 days, with mass production ready in 15-20 days after sample approval. More complex CNC machined components require 10-15 days for prototyping and 20-30 days for mass production. We always provide detailed production schedules at the time of order confirmation and keep clients updated on progress.
Can you help with product design optimization?
Absolutely. Our experienced engineering team regularly assists clients with design optimization to improve manufacturability and reduce costs. We can suggest modifications to material selection, wall thickness, bend radii, and other features based on our production capabilities. This service is particularly valuable for clients developing new products who want to ensure their designs can be efficiently produced while maintaining all functional requirements.
