Product Overview
Manufacturing a safe and standard gas cylinder starts with a flawless foundation. Our LPG Cylinder Moulds are engineered to withstand the extreme pressures of high-speed hydraulic presses. We provide a complete suite of tooling solutions-from the initial circular blanking to the final deep drawing and edge trimming-ensuring each cylinder half meets international safety standards like ISO4706 and EN1442.

Key Features & Advantages
Extreme Wear Resistance: We utilize vacuum-heat-treated alloy steel (Cr12MoV), which significantly reduces friction and prevents "galling" during the deep drawing process.
High Precision Consistency: Our CNC-machined die sets ensure that the upper and lower halves of the cylinder fit perfectly, facilitating a seamless welding process later in the production line.
Modular Design: The moulds are designed for easy maintenance. Wear-prone components can be replaced individually, reducing your long-term operational costs.
Optimized Material Flow: Specialized radius engineering prevents thinning and wrinkling of the steel sheets (HP295/SG295), ensuring uniform wall thickness.
The Production Cycle We Support
We don't just sell a "mould"; we provide a Total Tooling Solution for LPG bottle production:
Blanking Die: Cutting the steel coil into perfect circular discs.
First Deep Drawing: Transforming the disc into a cup shape.
Second Deep Drawing (Optional): For taller cylinder designs.
Edge Trimming & Joggling: Precise cutting and forming the "step" for the overlap weld.
Valve Boss Punching: Creating the hole for the collar and valve seat.
