How to get the most competitive quote?
To get the best price from die casting services, you need to provide a good Request for Quote (RFQ):
- Include complete STEP/IGS files: If the drawings are not clear, the vendor will likely add extra costs to the quote to cover the added risk.
- Be clear about tolerances: Not every hole needs to be accurate to ±0.02mm. Setting overly tight general tolerances might force the vendor to use expensive 5-axis finishing, increasing the price by 30% or more.
- Ask for tiered pricing: Request quotes for 50, 200, and 1000 pieces. This helps you see how productive they are and if they can handle moving from prototypes to small production runs.
How to Compare the Prices of Rapid Prototyping Service Providers
To make a rational decision, you must dismantle the hidden logic behind the PDF quote. True cost consists of four pillars:
- NRE/Tooling: Verify if the quote uses aluminum or steel. Aluminum is cheaper but dimensions drift after only 50 shots.
- Piece Price: Small-batch unit prices are often 3-5x higher than mass production due to machine setup costs.
- Secondary Ops: CNC machining can account for 40% of the total cost. Confirm if this is included.
- Logistics: Factor in air freight and potential tariffs (like the 25% US Section 301 tariff) early.
Industry Pitfall Avoidance Guide
When comparing prices, if you notice a supplier’s quote is unusually low, use the following criteria to audit them:
- Beware of “Low Mold Cost + High Modification Fees”: Some suppliers lure customers with extremely low mold setup fees, but after the first trial mold (T1), they charge modification fees nearly equal to the original mold cost—even for minor design changes.
- Verify DFM depth: Low-cost suppliers often produce molds directly from drawings without conducting fill simulations. This results in parts with severe internal porosity upon sampling, forcing you to pay additional mold fees for modifications.
- Material Authenticity Verification: Aluminum alloy prices fluctuate with the London Metal Exchange (LME). If quotes persistently fall below market raw material costs, suppliers may be incorporating recycled material. This can cause surface black spots or blistering during anodizing or plating of prototypes.
FAQs
How do I compare quotes from different die casting suppliers?
Look for a “Cost Breakdown.” If tooling is under $2,000, it’s likely a short-life aluminum mold. P20 steel molds cost 30% more but support over 1,000 stable injections, ensuring consistency.
What is the lead time for rapid die casting prototypes?
Standard lead times range from 2 to 4 weeks. A die casting manufacturer in china can often reduce this to 10 days by utilizing integrated industrial clusters. Always calculate lead time from the date of DFM approval, not the deposit date.
Why is prototype unit price so much higher than mass production?
It’s driven by “Setup Costs.” Every mold change takes 2-4 hours of machine time and trial material. When volume increases from 10 to 500 units, the unit price typically drops by over 60%.
