Frequently Asked Questions (FAQs)

How do I find reliable custom sheet metal manufacturers?
Start by searching online directories, trade platforms, or industry associations. Look for companies with good reviews, a robust website, and clear information about capabilities. Asking for referrals from industry peers can also point you to trusted suppliers.

What qualifications should I look for in a sheet metal factory?
Check for certifications like ISO 9001, experience with your type of project, advanced machinery, and a skilled workforce. It’s also important that they have strong quality control processes and clear communication practices.

How do I compare quotes from different manufacturers?
Beyond price, examine what’s included in each quote—such as materials, tolerances, lead times, and after-sales service. Consider the manufacturer’s reputation, production capabilities, and willingness to accommodate custom needs.

Can I request samples or prototypes before placing a large order?
Yes, reputable factories usually offer samples or prototypes to help you assess quality and fit. Be clear about your requirements and budget, as there may be additional charges for custom samples.

What should I ask about production lead times and order minimums?
Always confirm the average lead time for orders similar to yours and whether they can meet tight deadlines when needed. Also, ask about minimum order quantities (MOQs) to ensure their services align with your project size.
