Advanced Metallurgy & Heat Treatment
The heart of our tooling lies in its material composition. We utilize vacuum-heat-treated D2 or DC53 steel, achieving a hardness of HRC 60-62. This ensures that the drawing rims maintain their profile even under the intense friction of forming thick-gauge steel. The result is a significant extension in the intervals between die maintenance, directly boosting your factory's uptime.
Key Performance Attributes:
Synchronized Blank Holder Force: Our design integrates precision-tuned springs or nitrogen cylinders to provide constant pressure, preventing wrinkles even when the sheet metal thickness varies slightly.
Galling Resistance: The working surfaces undergo a specialized Vanadium Carbide (VC) or TD coating process, creating a mirror-like finish that allows the metal to glide, reducing the need for heavy lubricants.
Air-Venting System: Strategically placed vents prevent air-trapping during high-speed strokes, ensuring the extinguisher base is perfectly formed without vacuum-induced deformations.
Application Compatibility
Material Suitability: Optimized for SPCE, DC04, and HP295 deep-drawing steels.
Extinguisher Types: Ideal for 1kg to 12kg dry powder cylinders and high-pressure CO2 containers.
Press Integration: Fully compatible with automated transfer lines or manual hydraulic stations.
Commitment to Quality Control
We don't just ship steel; we ship verified performance. Each Fire Extinguisher Mould undergoes a "Blue Oil" test and a trial run of at least 50 samples before dispatch. We provide a full dimensional report for the stamped parts, ensuring that the critical neck and base diameters fall within your exact tolerance requirements.
