Professional Capabilities 02 / 05 · Performance Customization
Turn property requirements
into control across coils and batches.
Determine performance ranges such as tensile strength, elongation, and hardness around the customer’s part, while also monitoring fluctuations across coils and batches.
The customer’s requirements
The performance range must match the customer’s processing method.
The performance range needs to be clarified further
If the customer has specific requirements for tensile strength, elongation, or hardness, a project control range must be established.
Intra-coil or batch-to-batch variations affect machining
Even if a material meets general standards, its consistency still needs to be evaluated based on continuous processing performance.
Strength and ductility must be balanced
The final part requires high strength, while the raw material must also meet the deformation demands of subsequent cold forming.
Development approach
From target performance to process and sampling plans.
Jointly define the performance window
Considering wire diameter, part application, forming stations, and subsequent heat treatment, define key parameters and their allowable ranges.
Coordinating material and processing conditions
Evaluate raw materials, spheroidizing annealing, wire-drawing reduction ratios, and delivery conditions together, and organize corresponding trials and testing.
Confirm the consistency control method
Agree on sampling locations, frequency, and acceptance criteria, and continuously verify process stability by comparing in-coil and inter-batch results.
Projects and Case Studies
Examining different focuses of performance control across existing projects
The following are existing project directions; specific values and acceptance methods must align with the original project or a new technical agreement.
C4C · Control of properties throughout the coil
Include the consistency of properties across the entire coil in the project requirements.
10B21 · 1.92 mm
Performance and processing conditions of high-strength wire are developed in collaboration.
Sample dimensions and project names are used to illustrate development experience and do not imply that all wire diameters, conditions, or batches adhere to the same specifications.
Verification and Confirmation
Confirm materials and solutions using supporting evidence.
- Tensile strength, elongation, and hardness testing
- Perform sampling within the coil at the agreed locations.
- Comparison of batch results and verification of process records
- Joint confirmation of the customer’s forming results and material condition
Initiate project communication
Bring this information along to make technical discussions more precise.
For materials already available, initial discussions can proceed; any unclear conditions will be further confirmed by both parties.
- Material Grade, Wire Diameter, and Delivery Condition
- Individual performance targets and allowable ranges
- Sampling locations, frequency, and test methods
- Records of existing variations and customer processing performance
The achievable performance range depends on the material, dimensions, and processing conditions. Coil-wide and batch-level control are conducted according to the agreed sampling and acceptance plan; the performance of the entire material cannot be inferred from a single sample.
