stamping

Stamping process ‌ is a press and die to apply external force to plate, strip, pipe and profile to produce plastic deformation or separation, so as to obtain the required shape and size of the workpiece (stamping parts) forming processing method. Stamping process is widely used in automobiles, instruments, household appliances and other fields ‌.


According to the processing temperature, the stamping process can be divided into:


Hot stamping ‌ : suitable for sheet metal processing with high deformation resistance and poor plasticity ‌

‌Cold stamping ‌ : at room temperature, the common stamping method for sheet. ‌




Product Advantages of Carbon Steel Precision Stamped Filter Cap:





  • Superior Corrosion Resistance: The blue-white zinc plating forms a robust protective layer, effectively resisting oxidation, moisture, and chemical exposure, ensuring longevity in harsh environments (e.g., marine, industrial, or automotive applications).

  • High Precision & Consistency: Precision stamping technology guarantees dimensional accuracy (±0.05 mm tolerance), uniform wall thickness, and seamless integration with filter housings, eliminating leaks and enhancing system reliability.

  • Enhanced Mechanical Strength: Made from high-grade carbon steel, the cap delivers exceptional tensile strength and fatigue resistance, capable of withstanding high-pressure cycles and mechanical stress without deformation.

  • Customizable Design Flexibility: Tailored to client specifications, including diameter (5–100 mm), height, flange configurations, and threading, ensuring compatibility with diverse filtration systems (hydraulics, HVAC, oil/gas).

  • Aesthetic & Functional Finish: The blue-white zinc coating provides a smooth, reflective surface that minimizes friction during installation while offering a visually appealing finish for OEM components.

  • Cost-Effective Durability: Combines low material waste (via precision stamping) with extended service life, reducing replacement frequency and maintenance costs in applications like water treatment or industrial machinery.

  • Thermal Stability: Maintains structural integrity across a broad temperature range (-20°C to +150°C), suitable for thermal cycling environments such as engine filters or heat exchangers.

  • Ease of Installation: The open-end design simplifies assembly/disassembly, allowing quick integration into modular filtration systems without specialized tools.
