2025.8 Custom Case of Automotive Hardware Components: Numerical Control Technology Solves the Problem of Small Batch Processing

      As a custom factory for processing and manufacturing hardware products, we, with a complete range of precision equipment and a professional design engineering team, always solve customers' processing pain points based on technology. In August 2025, we completed the small batch customization of automotive hardware components for an automotive manufacturer using numerical control processing technology. This technology efficiently overcame its production difficulties. The following is the case details.

1. Customer Requirements and Core Challenges
The automotive manufacturer needed to customize a batch of small quantities (300 sets) of automotive chassis connection hardware components due to the requirements of new car research and development tests. The core requirements included:
Accuracy compliance: The key dimensions of the components must be controlled within ±0.02mm to meet the assembly accuracy of the chassis;
Emergency delivery: The components needed to be delivered within 10 days to support the subsequent research and development testing progress;
Cost control: Under the traditional processing mode, small batch orders were prone to cost overruns due to frequent equipment debugging and high scrap rates.
Previously, the factory that the customer had connected was unable to meet the requirements due to "difficulty in controlling the small batch accuracy and inability to compress the delivery cycle".

2. Technical Solution: Dual Guarantee of Numerical Control Equipment + Professional Team
To address the customer's pain points, we used high-precision numerical control processing centers and automatic lathes as the core processing equipment, combined with the design engineering team for full follow-up, and formulated a customized solution:
Precise processing: The numerical control equipment controls the accuracy

Using the numerical control processing center for the main cutting of the components, the equipment positioning accuracy reaches ±0.005mm, and through programming, multiple processes such as drilling and milling are completed automatically, avoiding the deviation in accuracy caused by manual operation; key parts are supplemented with fine turning by automatic lathes to ensure that the threads, chamfers, etc. meet the requirements of the drawings

Efficient production: Shorten debugging and cycle
The design engineering team used 3D modeling to simulate the processing flow in advance, optimized the tool paths and equipment parameters, reducing the equipment debugging time from the traditional 2 days to 8 hours; at the same time, the "process combination" mode was adopted to reduce the time for component circulation, and finally completed the processing of 300 sets of components in 7 days, 3 days earlier than the customer's requirements.

Cost optimization: Reduce waste and loss
The numerical control equipment optimizes the feed and cutting parameters through automation, increasing the material utilization rate from the traditional processing's 75% to 92%, reducing waste production; at the same time, eliminating the additional equipment debugging fees for small batch orders, helping the customer reduce 18% of the single set processing cost.

      We always rely on "equipment + technology + team" as our support. Whether it's auto and motorcycle parts, hardware components, beauty tools, or outdoor hardware, we can provide customized processing services according to the customer's batch requirements (from small batch trial production to large-scale production). If you have the need for processing of hardware finished products, please feel free to consult. Let our professional technology solve your production problems!
