In the fields of robot R&D and non-standard customization, many purchasing and engineering personnel are often perplexed: why do some manufacturers quote 300 yuan while others quote 1200 yuan for the same drawings? How deep is the “water” in processing fees?
To establish a transparent supply chain environment, today we will thoroughly break down the logic behind precision parts processing quotes, helping you spend every penny wisely.
I. Four Core Components of Precision Prototyping Prices
A standard prototyping quote is typically composed of the following formula: Total Price = Material Cost + Programming Cost + Machine Setup Cost + Processing Cost (Machine Time Cost) + Surface Treatment Cost.
Material Cost: This includes not only the volume of the part itself but also the waste of the blank. For special engineering plastics (such as PEEK) or expensive alloys (such as 17-4PH), the material cost percentage will increase significantly.
Fixed Costs (Programming and Machine Setup): This is the most expensive aspect of prototyping. Even for a single part, engineers spend several hours on CAM programming and machine tool setting. At Kzron, we try to minimize this expense through modular programming, but it remains a core component of unit cost.
Machining Costs (Machine Time): The machine time cost varies significantly depending on the complexity of the part, for 3-axis, 4-axis, and 5-axis robots. High-precision equipment (±0.005mm level) typically has a higher machine time unit price than ordinary equipment.
Surface Treatment and Inspection: Includes anodizing, electroless nickel plating, and coordinate measuring machine (CMM) inspection costs.
II. Why is producing 1 prototype so much more expensive than mass-producing 100?
This is due to the logic of “machine setup cost amortization.”
Assumption: For a robot joint component, programming + machine setup costs 500 yuan, and machining costs 100 yuan.
When making 1 unit: Unit price = 500 + 100 = 600 yuan.
When producing 100 pieces: Unit price = (500/100) + 100 = 105 yuan.
Therefore, the cost-effectiveness inflection point for small-batch non-standard parts processing usually occurs between 10-30 pieces.
II. Kzron’s Pricing Commitment: Open, Transparent, and Fast
As a trusted partner of robotics companies, Kzron adheres to the following principles:
24-Hour Quotation: Upon receiving drawings, we conduct precise calculations using a professional ERP quotation system, rejecting “quoting based on personal connections.”
No Minimum Order Quantity: We do not reject individual parts and proactively provide DFM suggestions to the R&D team, optimizing the processing flow from the design stage to reduce prices.
Transparent Precision Premium: If your parts require extreme precision of ±0.005mm, we will clearly inform you of the increased inspection and processing time, ensuring you understand that higher prices stem from higher quality.
III. Comparison Table of Processing Quotation Pitfalls
Price reflects service, but it should never be an insurmountable barrier. Kzron aims to lower the R&D entry barrier for companies needing small-batch non-standard parts machining through its transparent pricing logic. If you require small-batch non-standard parts machining, please feel free to send us your drawings. We will provide you with high-quality precision machining services based on the most honest cost accounting.
