What to Consider When Looking for Manufacturers?
Selecting a manufacturer is not just about price; it is about finding a long-term strategic partner. Here are the core factors to evaluate:
- Technical Capabilities: Does the factory have experience with your specific requirements? For example, if you need multi-material parts, look for expertise in 2-Shot Molding. If you need electronics integration, prioritize Insert Molding specialists.
- Production Volume: Some manufacturers (like Rodon) only accept orders in the millions, while others specialize in low-volume or prototype runs. Ensure their business model fits your forecasted demand.
- Certifications: For general manufacturing, ISO 9001 is the baseline. However, if you are in the automotive sector, TS 16949 is mandatory. For medical devices, look for ISO 13485.
- Turnaround Time: In competitive markets, speed is currency. Ask about their “T1” time (time to first trial sample). Agile manufacturers can often deliver T1 samples in as little as 15 days.
How to Verify a Reliable Supplier?
Before signing a contract or transferring a down payment, perform due diligence:
- Request a DFM (Design for Manufacturing) Report: A professional supplier will review your 3D files and provide a detailed report highlighting potential molding issues (draft angles, sink marks) within 24–48 hours. DFM is crucial for avoiding costly revisions.
- Check Quality Control Equipment: A reliable mold maker must have precise inspection equipment. Look for CMM (Coordinate Measuring Machines) and Vision Systems. Ask for sample CPK reports.
- Virtual or Physical Audit: If you cannot travel, request a live video tour of the factory floor. Pay attention to the organization of the CNC department and the cleanliness of the injection workshop.
- Ask for References: Request case studies similar to your project. A confident manufacturer will happily share their success stories.
