Blanking Production Line

LPG (Liquefied Petroleum Gas) cylinder production within the guidelines of the international standards such as ISO 4706,EN 1442 involves several process steps starting from forming to final testing that can be streamlined into the following lines,this is a set of procedures that must be followed by cylinder manufacturers in each country:
1.Blanking
2.Body Forming Production Line
3.Valve Guard Ring Production Line
4.Foot Ring Production Line
5.Valve Neck (Valve Boss or Neck Ring) Production Line
6.Welding,Heating
7.Hydrostatic Testing Line
8.Surface Coating Line
9.Finishing Line with Pneumatic Testing

We can provide a complete set of steel cylinder production solutions, and ensure that the production line costs the least and the production capacity is higher.Our aim is to help more people of regions or countries to use liquefied gas cylinders,more details please visit: www.cylindersupplier.com

The metal sheet blanking process is a crucial step in the manufacturing of steel LPG (liquefied petroleum gas) cylinders. Blanking involves cutting flat metal sheets into circular blanks, which will serve as the starting material for the subsequent deep drawing process. 

An overview of the metal sheet blanking process in LPG cylinder manufacturing:

Material Selection:
The manufacturing process begins with the selection of suitable steel sheets. The chosen material should meet specific requirements regarding thickness, strength, and other mechanical properties to ensure the safety and reliability of the final LPG cylinders.Generally, HP295 grade steel coil materials are selected.

Coil Unrolling (must be applicable):
In some cases, steel is supplied in the form of coils. If this is the case, the coil is unrolled to obtain flat sheets.

Sheet Cutting (Blanking):
The flat metal sheets are then cut into circular blanks using a hydraulic press with a die-cutting process.The circular blanks are cut to a size larger than the final dimensions of the LPG cylinder. This oversize accounts for material stretching during the deep drawing process.

Scrap Removal:
After cutting, there may be leftover material or scrap around the edges of the circular blanks. This excess material, known as "trim" or "scrap," is typically removed and recycled.

Quality Control:
The cut blanks undergo quality control checks to ensure they meet the specified dimensions and material properties.Any blanks that do not meet the quality standards may be rejected to maintain the integrity and safety of the LPG cylinders.

Stacking and Storage:
The approved blanks are then stacked and stored, ready for the subsequent deep drawing operations.Stacking is done carefully to prevent damage to the blanks and to maintain order in the manufacturing process.

The metal sheet blanking process is a preparatory step that provides the raw material in the form of circular blanks for the deep drawing process. It allows for efficient mass production by starting with uniform pieces that can be consistently formed into LPG cylinders. The precision and quality of the blanking process significantly impact the overall manufacturing process and the final product's safety and performance.
