Engineering Highlights
Advanced Deep Drawing Technology: Our metal Fire Extinguisher Moulds utilize a multi-stage drawing process to ensure uniform wall thickness, preventing thinning at the base which is critical for pressure resistance.
High-Wear Resistance: We use vacuum-quenched alloy steels (HRC 60+) for the drawing rings and punches, significantly reducing scratching and friction during high-speed production.
Integrated Component Solutions: Beyond the cylinder, we provide precision injection moulds for fire extinguisher valves, nozzles, hose grips, and plastic wall brackets.
Seamless Surface Quality: High-polish cavity finishing ensures the produced cylinders require minimal pre-treatment before powder coating.
Quality Control Standards
We treat every Fire Extinguisher Mould as a safety-critical tool. Our QC protocol includes:
Simulation Analysis: Using AutoForm or Moldflow to predict stress distribution and prevent wrinkling or tearing during the drawing phase.
CMM Inspection: 3D Coordinate Measuring Machine verification to ensure every curve of the dome and base matches the safety blueprint.
Hardness Testing: Verifying the heat treatment consistency across all moving parts of the die.
Pressure Trial: Producing sample shells and subjecting them to hydraulic burst tests to validate the mould's performance.
Customization & OEM Services
We offer complete flexibility in design:
Logo Embossing: Integrated stamps for permanent brand marking or manufacturing dates on the cylinder neck.
Specific Bottom Shapes: Concave or ring-welded base designs according to regional market preferences.
Automated Line Compatibility: Our moulds are designed to be easily integrated into fully automated hydraulic press lines.
FAQ
Q: How do you prevent scratches on the surface of the cylinder during drawing?
A: We apply a specialized PVD coating or hard chrome plating to the mould surface and optimize the lubrication grooves to ensure smooth material flow.
Q: What is the typical lifespan of your Fire Extinguisher Mould?
A: With proper maintenance and lubrication, our premium alloy steel moulds typically exceed 800,000 strokes. We also provide a set of wearing parts (punches/springs) with every shipment.
Q: Can you design the mould based on our specific safety standard (e.g., EN3)?
A: Yes, our engineers will calculate the thinning ratio and draw depth to ensure the final product exceeds the burst pressure requirements of your local standards.
