Custom Non-Standard Nut Tapping Equipment Project for an Auto Parts Enterprise

A Benchmark in Custom Automated Equipment, Empowering Global Manufacturing Upgrade

· Case

Customer Needs

A leading domestic auto parts manufacturer required high-precision tapping processing for a special-specification T-thread welding nut to support the R&D of a new car model. The nut featured a unique structure and strict dimensional tolerance requirements (±0.02mm), which could not be met by traditional standard equipment. Additionally, the customer needed mass production capacity (daily output ≥ 5,000 units) and demanded automated loading and unloading functions to reduce labor costs.

Solutions

Zheqiang Machinery established a dedicated R&D team to conduct in-depth on-site investigations at the customer's production facility and developed a customized design based on their process requirements:

  1. Optimized core equipment mechanism: Adopted high-precision ball screws, servo drive systems, and customized tapping tools to ensure tapping accuracy meets the customer's tolerance standards.
  2. Integrated automated modules: Added automatic feeding devices with vibratory bowls, visual positioning systems, and finished product sorting mechanisms to achieve full-process automation from raw material conveying and positioning processing to finished product collection.
  3. Upgraded control system: Equipped with an industrial touch screen to support flexible parameter adjustment and real-time monitoring of production data, facilitating the customer's process optimization and capacity management.

Cooperation Achievements

  1. Meeting processing accuracy requirements: The equipment's tapping qualification rate remained stable above 99.8%, fully satisfying the customer's high-precision processing needs for special nuts.
  2. Efficient capacity improvement: The daily output reached 6,000 units, exceeding the customer's expectations and supporting the smooth advancement of their new car model mass production plan.
  3. Significant cost reduction and efficiency improvement: After automation transformation, labor input for a single production line was reduced by 80%, production efficiency increased by 3 times, and the customer's overall production costs decreased by 40%.
  4. Long-term stable operation: The equipment operated continuously for 18 months without major failures, with timely after-sales service responses. It gained high recognition from the customer, who subsequently placed orders for 3 additional custom equipment of the same series.
