**Automatic LPG Gas Cylinder Production Line**
The complete production line includes various machines that work together to manufacture high-quality LPG cylinders efficiently. Below is a list of the key machines in the system:
**Production Process**
**Mechanical Decoiler, Straightening, and Blanking Line**
**Deep Drawing Machine**
After the sheet metal is cut and prepared, it is formed into the shape of the cylinder head using a deep drawing machine.
**Automatic Flushing Machine for Deep Drawn Heads**
Once the heads are drawn, they must be cleaned before moving to the next stage of the process.
**Automatic Trimming & Polishing Machine with Arms for Both End Dishes**
This machine uses air-jacket clamping and automatic feeding. It trims and polishes both ends of the cylinder efficiently, ensuring a smooth finish.
**Automatic Hole Punching & Logo Making Machine with Arms for Female Half/Top Half**
This machine punches holes on the top of the cylinder and stamps the logo onto the surface.
**Automatic Socket Welding Machine with Arms**
Used to weld the valve seat ring joints. The process ensures uniform forming, good appearance, and proper weld penetration.
**Automatic Handle Welding Machine with Arms**
This machine performs automatic welding of the handle grip. It ensures concentricity, uniform forming, and meets all technical requirements.
**Automatic Joggling Machine with Arms for Male Half/Bottom Half**
Equipped with conveyors and mechanical arms, this machine ensures smooth handling and processing of the bottom half of the cylinder.
**Automatic Bottom Base Welding Machine with Arms**
This machine completes the girth welding of the base, ensuring quality and precision.
**Longitudinal Seam Welding Machine**
Designed for larger cylinders (not suitable for 12.5 kg or smaller sizes).
**Assembly & Spot Welding Machine**
This machine assembles the two halves of the cylinder and prepares them for full welding.
**Double Head Circumferential Welding Machine**
Fully automatic and monitored, this machine ensures consistent and high-quality welding.
**Hydraulic Precision Sheet Shearing Machine**
For precise cutting of sheet materials.
**Four-Roller Rolling Machine**
Includes loading and unloading systems for efficient rolling of steel sheets.
**LPG Gas Furnace**
Designed for heat treatment of LPG cylinders using gas burners. Features adjustable time, self-controlled temperature, and pollution-free operation.
**Automatic Hydro Testing Machine**
For testing 35 kg cylinders. Each cylinder has its own pressure gauge and can be tested individually.
**Drying Oven**
Ensures the cylinder is dry before blasting.
**Shot Blasting Machine**
Removes rust, oxide layers, and burrs from the cylinder, leaving a clean and bright surface.
**Zinc Metalizing Machine**
Improves corrosion resistance and surface adhesion.
**Powder Coating Line**
Protects the cylinder from rust by applying a durable coating.
**Valve Mounting Machine**
Mounts the valve on the cylinder.
**Automatic Air Leakage Testing Machine**
Detects leaks automatically and efficiently.
**Printing Machine**
Prints logos, information, and other details on the cylinder.
**Conveyor System**
Includes motors and bends for smooth movement of parts through the production line.
**Steel Coil Decoiler and Straightener**
Prepares raw material for further processing.
**315 Ton Hydraulic Presser**
Used for stamping operations on handles.
**200T Mechanical Punching Machine**
Punches holes in the steel sheet.
**Handle End Bending Machine**
Bends the end of the handle (optional).
**Handle Rolling Machine**
Rolls steel into the desired handle shape.
**160T Hydraulic Presser**
Used for various pressing tasks.
**Hydraulic Coding Machine**
Applies codes or labels to the cylinder.
**Vertical Base Rolling Machine**
Rolls the base of the cylinder.
**Double Welding Position Welding Fixture**
Allows for simultaneous welding at two positions.
**Base Forming Machine / 100T Mechanical Punching Machine**
Forms the base of the cylinder.
