When it comes to aerosol packaging, the can body gets all the attention — but the real sealing happens at the top. The cone and dome assembly is where pressure integrity, valve performance, and user safety converge. At our factory, we manufacture a full range of aerosol cones and domes compatible with industry-standard valves, available in both stock specifications and custom-engineered sizes for OEM aerosol brands worldwide.

What Are Cones & Domes?

In aerosol terminology, the cone (also called the cone top) is the lower portion of the aerosol cap assembly — the part that forms the sealing seat for the valve cup. The dome is the upper, curved portion that gives the can its finished profile and often carries embossed text, recycling marks, or brand identifiers.

Together, the cone and dome are crimped onto the can body, creating an airtight, pressure-rated seal that must withstand internal pressures ranging from 6 bar to over 15 bar depending on the propellant system.

Specifications at a Glance

Why Component Quality Matters

A poorly manufactured cone or dome can cause:

• Valve leakage — improper seating leads to slow pressure loss

• Crimp failure — weak dome material cracks during can crimping

• Inconsistent spray — poor sealing disrupts valve actuation

• Safety risk — pressure failure under high-temperature storage

Our cones and domes are produced on precision stamping lines with strict dimensional tolerance control (±0.05 mm), ensuring consistent valve seating, reliable crimping, and long-term pressure retention.

Compatibility & Valve Matching

We manufacture cones and domes compatible with major valve standards:

• FEA 410 — standard for personal care and household (1-inch valve)

• FEA 500 — industrial and technical applications

• FEA 600 — high-performance and specialty formulations

• 20 mm valves — pharmaceuticals, nasal sprays, food-grade applications

We work closely with leading valve manufacturers including Lindal, Summit, Precision, and Coster, ensuring our cones and domes accept their valve cups without modification.

Custom Sizes & Special Profiles

While stock 1-inch and 20 mm cones/domes cover most applications, we also support:

• Non-standard opening diameters for proprietary valve systems

• Custom dome heights to match unique can body proportions

• Special embossing — logos, QR codes, batch codes, regulatory markings

• Dual-material assemblies — tinplate cone + aluminum dome combinations

• Colored domes — matched to brand color palette (Pantone-matched lacquers)

• Vented domes — for specific pressure-release applications
  
  

Applications by Industry

Quality Assurance

Every production batch undergoes:

• Dimensional inspection — cone opening diameter, dome height, wall thickness

• Coating thickness test — internal and external lacquer measurement

• Adhesion test — cross-cut and bend testing on coated surfaces

• Crimp simulation — test crimping on sample cans to verify seal integrity

• Pressure test — sample cans filled and pressure-cycled to specification

All production is traceable by batch number, with COA (Certificate of Analysis) available on request.
