Semi-Automatic Butane Gas Filling Machine: Your Safe, Precise Solution for Cartridge Gas Production

1.Product Core Positioning: “Safe and Efficient Solution” for Small and Medium Batch Cassette Gas Production

Semi-automatic cassette gas filling machine is the core equipment designed for filling butane gas, propane gas and other flammable gases, integrating the three functional units of independent vacuum pump, sealing machine and filling machine, supporting 3-station collaborative operation (3 people can work efficiently with the cooperation), which can meet the demand for large-scale production of portable fuels without the need for complex automation transformation.

Compared with the high cost and high capacity threshold of fully automated production line, this equipment is more suitable for the production rhythm of small and medium-sized manufacturers and regional brands - it can not only cope with the stable output of 500-1000 cans/hour, but also flexibly adjust the order batch to avoid capacity wastage, which is the best way for the cassette gas to move from the “small batch trial production” to the “regular production”. It is the cost-effective choice from “small batch trial production” to “regularized production” of cassette gas.

3.3 Steps Filling Process: Simple Operation, Safe and Controllable

The core process of the equipment can be started by ordinary workers after 1 hour of training without the need of professional technicians:

Vacuum pre-treatment (anti-mixing・solid valve)

The equipment completely extracts the air from the gas tank through an independent vacuum pump, which prevents the air in the tank from mixing with the butane and causing safety hazards on the one hand, and on the other hand, the valve is initially pressed tightly by atmospheric pressure, which lays the foundation for the subsequent sealing.

Tight sealing (preventing leakage and ensuring safety)

The sealing module automatically presses and locks the interface between the valve and the gas tank, adopting high-precision pressing technology to ensure that there is no gap at the interface, thus preventing leakage after filling from the source.

Accurate Filling (Dosage Control・Corrosion Prevention)

The filling system injects butane gas according to the preset capacity, and the gas line interface adopts PTFE seals (butane corrosion resistance and strong sealing) to avoid gas spillage during the filling process, and the handwheel fine-tuning function can correct the dosage in real time to ensure that the accuracy of each can is up to the standard.

4. 4 Core Advantages: Solve the “Safety, Cost, Efficiency” Pain Points of Cassette Gas Production

(1) Zero Electricity Explosion-proof Design -- The “Safety Bottom Line” of Flammable Gas Filling

Pure pneumatic drive, without any electrical components. Pure pneumatic drive, without any electrical components, to avoid sparks from the root, in full compliance with the safety standards for the production of flammable gases such as butane, propane, etc., the workshop does not need to configure additional explosion-proof circuits, reducing the cost of safety modification.

(2) Precise and controllable -- Reduce raw material waste, improve product consistency

Handwheel fine-tuning: according to different product requirements (such as lighter gas, camping gas) to quickly switch the filling volume;

Error ≤ ± 1%: according to the calculation of 800 cans in a single day, each can of 200 ml, the daily waste of raw materials can be controlled within 160 ml, long-term use of a significant reduction in costs. Reducing costs in the long run.

(3)  Efficient and flexible - adapting to the rhythm of small batch and multi-batch production.

Foot-triggered: single-can filling only requires “stepping on the pedal”, easy to operate, and workers can quickly switch between different sizes of canisters.

Rapid response: there is no need to wait for the production line to warm up or change the molds, and when receiving small orders (e.g., 500 cans), it is easy to switch between different sizes. Quick response: no need to wait for the production line to warm up or change molds, small orders (e.g. 500 cans for emergency replenishment) can be started immediately, shortening the delivery cycle.

(4) Low Maintenance Costs -- Reduce downtime and prolong equipment life.

Modular design: vacuum pump, sealing machine, filling machine units are independently split, if a part fails, you only need to replace the corresponding module, no need to overhaul the whole machine.

Durable material: 316L stainless steel air line + PTFE seals, corrosion and abrasion resistance, maintenance costs are 40% lower than ordinary equipment. Durable material: 316L stainless steel air line + PTFE seals, anti-corrosion, wear-resistant, maintenance cost 40% lower than ordinary equipment.

6.FAQ: Answering the core questions of the production side

Q1: Does the equipment need to be configured separately for explosion-proof workshop?

A1: There is no need for additional remodeling. The equipment itself is purely pneumatic in design, with no risk of electrical sparks. As long as the workshop meets the standard of conventional industrial production (well ventilated and away from open flames), it can be installed and used directly.

Q2: Can it be filled with other gases besides butane gas?

A2: It is compatible with propane gas, liquefied gas and other liquefied gases with similar properties to butane. If you need to fill special gases (such as high-purity gases), you can contact us to customize the material of the gas line and seals.

Q3: The specification of gas tank exceeds “70-330mm height”, can it be adapted?

A3: We support customization. According to the height and caliber of your gas tank, we can adjust the size of the conveying track and sealing module of the equipment.

Q4：How to ensure the production is not interrupted when the equipment fails?

A4：We provide “spare module emergency service” - when purchasing the equipment can be additional optional vacuum pump, filling head spare module, direct replacement in case of failure; at the same time, 24-hour online technical support, video guidance for maintenance, general small faults can be solved within 30 minutes. The general small faults can be solved within 30 minutes.
