Introduction
Aerosol production lines often face a specific bottleneck: the valve insertion step. For products with standard 1-inch valves, manual valve placement is still common in many small to mid-sized operations—but it introduces inconsistency, slower throughput, and increased labor costs.
This article examines a customized automatic rotary aerosol filling, sealing, and crimping machine designed to address these challenges. We’ll look at how the rotary system integrates filling, valve insertion, and crimping into a single automated workflow, and what manufacturers should consider before investing in this type of equipment.
How the Machine Works
The machine is organized around a rotary indexing table that moves aerosol cans through three sequential stations:
- Filling station – Two filling heads dispense liquid product into the aerosol can. Each head has a maximum fill volume of 300 ml, and the system achieves a filling accuracy of ≤ ±1g.
- Valve insertion station – An automatic valve installation device, equipped with a vibratory bowl feeder, positions and inserts valves into the filled cans. The vibratory motor orients and feeds valves consistently, eliminating manual handling.
- Crimping station – The sealing and crimping device permanently attaches the valve to the can, completing the closure with specific sealing diameter (27.1–27.3 mm) and sealing depth (5.0–5.2 mm) parameters.
The machine is designed for valves without tail pipes—commonly used in products like foam adhesives and gelling agents where no dip tube is required. The entire process from can loading to crimped output runs automatically once the machine is set up and in operation.
Suitable Applications
This rotary machine is specifically configured for aerosol products without tail valves. Based on the provided specifications, it is suitable for:
- Foam adhesives – Such as spray foam insulation and construction adhesives
- Gelling agents – Including aerosol-based gel products
The machine accommodates:
- Can diameters from 35 mm to 70 mm
- Can heights from 80 mm to 315 mm
- Standard 1-inch valves (customizable to other sizes)
With a production capacity of 1,500–1,800 cans per hour, this equipment is positioned for manufacturers operating at medium scale—above manual or semi-automatic lines, but below high-speed rotary systems exceeding 3,000+ cans per hour.
Key Features and Why They Matter
Rotary indexing table design ensures each can receives the same sequence of operations with minimal variation between cycles. Compared to inline systems, rotary designs typically offer a smaller footprint for the same number of stations, and indexing provides positive positioning during valve insertion and crimping.
Dual filling heads enable simultaneous filling of two cans per cycle, contributing to the 1,500–1,800 bph output. This configuration balances throughput with machine complexity—more heads would increase speed but also increase cost and maintenance requirements.
Automatic valve insertion with vibratory feeder addresses one of the more labor-intensive steps in aerosol production. Vibratory bowl feeders reliably separate and orient valves for pickup and insertion, reducing the need for manual valve placement and the inconsistency that comes with it.
Customizable valve size allows the machine to accommodate non-standard valve configurations beyond the standard 1-inch. This is relevant for manufacturers using proprietary valve designs or specific customer requirements.
Stainless steel construction (inferred from the application with adhesives and gels) provides resistance to corrosion and facilitates cleaning when switching between formulations.
Crimping precision with specified sealing diameter and depth ranges ensures the valve is securely attached without damaging the gasket or valve components. A crimp that is too shallow may leak; one that is too deep can deform the valve or can. Having defined parameters allows for repeatable setup.
Robust power requirements at 3-phase 380V, 50Hz indicate this machine is intended for industrial facilities with standard three-phase power availability.

When to Choose This Machine
This customized rotary aerosol machine is worth considering if your production profile includes:
No-tail-valve products. The machine is specifically configured for valves without dip tubes—common in foam adhesives, sealants, and gel-type aerosols. If your product uses a standard valve with a tail pipe, a different valve feeding system would be required.
Production targets between 1,500 and 1,800 cans per hour. This capacity sits between semi-automatic lines (typically 400–800 cans/hour) and high-output rotary lines (3,000+ cans/hour). It is well-suited for manufacturers scaling up from manual or semi-automatic operations.
Multiple can sizes. The machine accommodates can diameters from 35 mm to 70 mm and heights from 80 mm to 315 mm. If your product range includes multiple can dimensions, this flexibility reduces the need for dedicated equipment per size.
Standard or custom valve sizes. While the machine ships with 1-inch tooling, the valve size is customizable. Manufacturers using non-standard valves should confirm customization options with the supplier.
Space availability. The complete configuration including conveyor measures approximately 3,000 mm in length. The rotary table itself occupies about 960 × 1,220 mm. Ensure your floor plan accommodates the full equipment footprint and operator access.
What to Confirm Before Buying
Before purchasing a customized rotary aerosol filling and sealing machine, confirm the following with your supplier:
- Product type and viscosity. The two-head filling system can handle liquids, but the specific viscosity range should be verified. Adhesives and gels vary significantly in flow characteristics, which can affect fill accuracy and pump selection.
- Valve type and dimensions. Confirm valve diameter, stem length, and whether the valve includes a tail pipe. The vibratory feeder bowl is typically tooled for a specific valve design.
- Can dimensions. Provide can samples (diameter, height, and neck finish) so the supplier can verify compatibility with the conveyor and indexing stations. Can manufacturers may use slightly different specifications that affect fit.
- Required crimping parameters. Sealing diameter (27.1–27.3 mm) and depth (5.0–5.2 mm) are specified. Confirm these match your valve/can combination and product sealing requirements.
- Power supply. Confirm your facility has 3-phase 380V, 50Hz power available, or discuss voltage options with the supplier if your region uses different standards.
- Conveyor configuration. The machine is supplied with or without a conveyor. Confirm whether your existing conveyor system can integrate, or whether the supplied conveyor length (approximately 3,000 mm total system length) works with your layout.
- Material compatibility. For adhesive and gel applications, confirm that all wetted parts are compatible with your specific formulation.
FAQ
1. What is the difference between a rotary aerosol filling machine and an inline aerosol filling machine?
In a rotary machine, cans move through the process on an indexing turntable, with each station positioned around the circumference. This design typically requires less floor space for multiple operations and provides positive can positioning. Inline machines process cans in a straight line; they are often more modular but can be longer.
2. Can this machine fill products with tail valves?
No. The valve insertion device in this configuration is designed for valves without tail pipes. If your product requires a tail valve (with a dip tube extending into the product), the valve feeding and insertion system would need to be reconfigured. Check with your supplier for the appropriate design.
3. How long does changeover take for different can sizes?
Changeover time depends on the extent of adjustment required. Can height adjustments are typically quicker than diameter or valve size changes. Valve size changes may require changing the feeder bowl tooling and crimping heads. Confirm estimated changeover times with your supplier based on your specific can and valve combinations.
4. What is the difference between standard 1-inch valves and “tail valves”?
A standard 1-inch valve is a general term for aerosol valves with a 1-inch mounting cup. “Tail valve” typically refers to a valve with a dip tube that extends into the product. “No-tail-valve” products use a different valve design—often for products like foam adhesives where the product is discharged in a foamed or expanded state and does not require a dip tube.
Conclusion
The customized automatic rotary aerosol filling and sealing machine offers a practical path for manufacturers of foam adhesives, gelling agents, and other no-tail-valve aerosol products looking to automate the filling-valve insertion-crimping process. With a capacity of 1,500–1,800 cans per hour and flexible can size accommodation, it bridges the gap between manual operation and high-speed production.
