CNC Automated Precision Machining: Stainless Steel Terminals for New Energy Vehicles

I. Company Introduction

Dongguan Ganyuan Hardware Technology Co., Ltd. specializes in precision hardware machining for high-voltage connections in the new energy vehicle industry. 304 stainless steel terminals are core components of new energy vehicle wiring harness systems. Serving new energy vehicle manufacturers and high-voltage wiring harness companies, the company is equipped with CNC lathes, four-axis machining centers, five-axis machining centers, and a complete CNC automated production line encompassing turning and milling. The entire line adheres to the ISO9001:2015 quality management system, supporting non-standard customization based on drawings and samples, and balancing small-batch prototyping with large-scale automated mass production delivery.

II. Full-Chain CNC Equipment Cluster: Micron-Level Control of Terminal Precision Dimensions

Stainless steel terminals feature a multi-step outer diameter, precision internal threads, and a positioning slotted composite structure. The integrity of the thread, the coaxiality of the shaft, and the step dimensions directly determine the tightness and conductivity stability of the high-voltage wiring harness connection. Our factory's digital machining system boasts significant advantages:

In the pre-production stage, 3D programming simulation and intelligent toolpath planning are completed. The entire process, including external turning, internal boring, precision tapping, and positioning grooving, is completed in a single workpiece clamping. Machining accuracy reaches ±0.005mm, and machining efficiency is 30% higher than traditional lathes.

Multi-axis linkage milling and turning equipment integrates steps and internal threads, avoiding circular runout deviations caused by multiple clampings. This overcomes the machining difficulties of high hardness and easy stripping of threads in stainless steel. Each batch of terminals has uniform dimensions, ensuring a perfect fit with no play in the assembly.

III. Standardized and Automated Production Processes for High-Quality Stainless Steel Terminals for Automotive Use

Complete Automated Production Process
Raw Material CNC Cutting: Utilizing original 304 stainless steel solid bars, automatically cut to length, ensuring uniform material without porosity and a stable, corrosion-resistant base.
CNC Precision Turning: Machining a two-step outer diameter, strictly controlling outer diameter tolerances to ensure smooth insertion and removal of the wire harness sheath.
High-Precision Boring and Tapping: Precision machining of internal threads, resulting in full and smooth tooth profiles; thread gauges are fully inspected for stripping.

Milling Positioning and Anti-Rotation Slots: Side slotting for locking and anti-rotation after assembly, preventing loosening under high-voltage conditions.
Surface Deburring and Polishing: Removing sharp burrs from the cutting edge to avoid scratching the wire harness insulation layer.
Full-Dimension Factory Inspection: Thread, outer diameter, and coaxiality are inspected item by item to reject defective products.

Three Core Advantages of Stainless Steel Terminals:

304 Stainless Steel Base Material, Strong Corrosion Resistance
Made of virgin 304 stainless steel, it is oxidation-resistant, salt spray-resistant, and resistant to high-temperature oil stains. It is not prone to rusting even in the humid and temperature-varying environments of new energy vehicle engine compartments, ensuring long-term stable high-voltage connections.

Micron-Level Precision Machining, Highly Accurate Dimensions
Strict tolerance control for steps, internal threads, and positioning grooves ensures a tight, seamless mating of male and female terminals, providing a secure and gapless lock-in, stable current conduction, and reducing the risk of overheating.

Suitable for New Energy Vehicle Wiring Harness Scenarios, Safe and Durable
Designed specifically for high-voltage wiring harness connections in new energy vehicles, it is highly rigid and vibration-resistant, preventing loosening even under bumpy driving conditions, significantly improving the safety and lifespan of the overall vehicle electrical connections.

IV. ISO9001 Closed-Loop Quality Control, Compliant with Stringent Standards for Automotive Parts

The company holds GB/T19001-2016 (ISO9001:2015) quality management system certification, establishing automotive-grade full-process quality inspection standards:

Raw materials undergo spectral testing upon arrival; automated inspection is implemented for turning and tapping processes; finished products undergo full inspection using calipers, roundness testers, and thread gauges to eliminate defects such as stripped threads, out-of-tolerance outer diameters, and sharp burrs, fully meeting the access standards for new energy vehicle wiring harnesses.

V. Multi-Layer Anti-static Cushioning Packaging, Damage-Free Sea and Land Transportation

Precision threads and stepped surfaces are highly susceptible to scratches and damage. Finished stainless steel terminals are individually packaged in anti-static plastic bags, then further packaged in pearl cotton slots, and finally reinforced with thickened cardboard boxes. For large-volume export orders for complete vehicles, custom-made solid wood protective crates are available, providing moisture and shock protection, ensuring the integrity of the workpieces during domestic land transportation and ocean shipping.

VI. One-stop Non-standard Customization, Deeply Rooted in the New Energy Connection Accessories Market

Ganyuan Hardware offers customizable 304/316 stainless steel terminals, stepped connecting nuts, and slotted terminals, supporting processing based on drawings for any outer diameter, length, thread specification, and slotted structure. Leveraging a mature automated milling and turning production line, we strictly control machining tolerances to ±0.005mm, providing corrosion-resistant, high-precision, and reliable stainless steel terminal components for manufacturers of new energy vehicles, energy storage, and industrial high-voltage wiring harnesses.
