In-die Tapping Technology
The stamping die for this tapping product has been in operation for over five years, accumulating tens of millions of stamping cycles.
Incorprated tapping device to stamping dies to carry on threading/tapping and stampings imultaneously. That’s why we called “in-die tapping”.
Advantage: In-die Tapping technology can effectively avoid the secondary processing error of missing tapping and reduce the cost of secondary processing……
Integrated Threading in Progressive Die Stages
This in‑die threading solution from ZYLY incorporates the threading process directly into the progressive stamping mold. Threading is performed as one of the operations during continuous feeding of the strip, enabling threaded parts to be formed in sync with blanking, piercing, and bending. This reduces handling between machines and eliminates the need for post-stamping threading or tapping equipment. With robust mold design, the process ensures alignment between the punched hole and the thread path. As a supplier of custom metal stamping components, ZYLY provides in‑die solutions that reduce time while meeting strict dimensional standards, ensuring compatibility with automotive stamping dies used in mass production.
Engineering Design for Precise Threading
The threading mechanism inside the mold is designed to engage only at the specified station and angle, cutting or forming threads with controlled torque application. To maintain the mold’s service life and threading consistency, wear-resistant materials are chosen for the thread-forming tools, and the threading station is structurally reinforced. ZYLY’s mold engineers ensure that every step—from pilot hole piercing to threading—is in precise alignment. Tolerances are tightly managed through tool simulation and pilot runs. These automotive stamping dies support complex geometries and thread profiles, allowing for internal thread formation within high-speed custom metal stamping workflows.
Stable Output Under High Production Loads
In-die threading is suitable for continuous, large-volume production. The mold is built to withstand repeated threading cycles without thread quality degradation. Thread inserts and hardened cavities are replaceable, and ZYLY’s internal maintenance system includes inspection intervals based on stroke count and part performance metrics. Threading torque, stroke timing, and material feed alignment are verified through in-die monitoring to ensure consistent thread shape and pitch. This ensures long-run stability, a key requirement in automotive metal stamping, where downtime is costly. ZYLY’s in-die threading system brings productivity and reliability into a unified mold platform that serves large-scale manufacturers using automotive stamping dies.
Product Advantages
Single-Process Threaded Part Production
This solution allows internal threads to be stamped within the same mold cycle, removing the need for secondary tapping. The threading is completed before the part exits the press, improving line efficiency and minimizing operator involvement. This feature is valuable for customers demanding custom metal stamping services that deliver near-net shape components. The benefit is magnified in automotive stamping dies, where full integration into press lines enhances efficiency and part readiness.
Precision in Thread Alignment and Pitch Control
Each threaded feature is generated using dies configured for alignment with pre-pierced holes, ensuring threads are concentric and meet required pitch dimensions. The die mechanism maintains consistent torque, feed angle, and stroke timing to produce high-quality threads across long production runs. This is especially beneficial in high-accuracy custom metal stamping applications, where threaded features must remain reliable under structural loads in automotive assemblies. ZYLY’s integrated tooling ensures that automotive stamping dies consistently produce fully threaded parts that require no further machining.
Enhanced Mold Durability with Reduced Downtime
The die’s threading components are constructed from high-strength materials that resist wear, and the mold frame includes hardened zones to absorb torque and impact during thread forming. Interchangeable inserts and serviceable threading stations make maintenance straightforward. ZYLY incorporates threading load simulation and real-time monitoring to detect early signs of wear. For manufacturers using automotive stamping dies, this translates into long-lasting mold performance and fewer unplanned line stoppages. It also supports predictable costs over extended custom metal stamping projects.
Use Scenarios
Fastener-Ready Stamped Components
This threading method is ideal for parts that need immediate fastening without downstream machining. Whether for brackets, support plates, or electronic housings, ZYLY’s solution provides stamped components with functional threads from the press. In industries requiring custom metal stamping, this capability is especially valuable when threading is a required assembly feature. Within automotive stamping dies, this supports chassis or body applications where fasteners are installed at the next production stage.
High-Speed Press Line Integration
The mold is designed to work in high-speed progressive press lines, where threading must occur without interrupting stroke cadence. This makes it ideal for high-volume manufacturers looking to optimize their line flow without additional processes. The in-die threading feature supports seamless operation in synchronized stations. When integrated into automotive stamping dies, the system helps ensure tight takt times are maintained without sacrificing part precision. It’s a production advantage for OEMs seeking long-term stability in custom metal stamping workflows.
Threaded Prototypes in Full-Scale Trials
In pre-production phases, the same mold architecture supports trial runs that closely simulate mass production. This enables validation of threading performance, pitch consistency, and alignment without switching tooling. ZYLY’s engineering team can refine the die before final delivery, ensuring tooling is tailored to actual part requirements. It provides flexibility for customers developing parts that demand functional threads early in the product lifecycle. Especially for automotive metal stamping, this enables reduced lead times from design to delivery.
