The application history of the three-piece can has been nearly 200 years, although it has been improved many times, its basic composition is still made of three metal sheets (mostly tinplate) from the body of the can, the bottom of the can and the lid of the can, so it is named "three-piece can". Its shape, size and manufacturing method of the bottom and lid of the ordinary three-piece can are exactly the same, collectively referred to as the lid. There are two main sealing forms of the longitudinal seam of the tank body: tin welding and fusion welding. The former was used earlier, but it has been eliminated because of the lead in the solder. The latter can avoid lead pollution, low energy consumption, less material consumption, but the production equipment is complex. The three-piece can has the characteristics of good rigidity, can produce cans of various shapes, high material utilization rate, easy to change size, mature production process, and many kinds of packaging products.

For the whole aerosol products, aerosol cans are an important part, it not only bears the role of the appearance of the packaging, but also adhere to the responsibility of the product leakage. At the same time, aerosol cans as the main body of high pressure resistance, but also aerosol product leakage, corrosion of the high incidence of the site. So how to select the aerosol cans, the production of aerosol products, is the first and second most important. Usually we are classified according to the material of the can. Currently, there are two common types on the market: tinplate aerosol cans and aluminium aerosol cans. Among them, tinplate cans are the aerosol products in larger quantities, but also more affordable aerosol cans. From the shape can be divided into straight-wall cans, necked-in cans and so on. Necked-In Cans Straight-Wall Cans From the internal coating, can be divided into plain cans and internal coating cans. Plain Inside                                                Golden Lacquered Inside From the manufacturing structure can be divided into three-piece cans, two-piece cans and so on. Three-piece Cans Guangdong Sihai specialises in manufacturing three-piece empty aerosol tin cans, with 25 years of experience, and has been committed to producing the safest aerosol cans.

Key points for choosing aerosol cans 1. Stability/compatibility For any aerosol can product, the first thing is to ensure the stability and reliability of the product. The cans of the selected products are tested for compatibility and stability based on the type of product and the characteristics of the formula. Only with data support can we have a theoretical basis for products to flow into the market. Of course, the stability test does not mean that there is no problem 100%. It is only a representative test. There may be unknown problems in the follow-up, but it can represent the vast majority. 2. Security Safety is the first priority for any project. The safety here includes usage safety, pressure safety, environmental safety, toxicological safety, the proportion of the contents in the aerosol can’s full water weight, etc. What R&D engineers develop is not only products that can bring profits to the boss, but more importantly, safe products that can bring benefits to society. 3. Economical Excessive use of packaging materials is actually a waste of resources, so choosing suitable packaging materials is a suitable way to protect resources.

The working principle of aerosol canister spray mainly depends on the internal pressure,and the interaction of the liquid and the nozzle. The inside of the aerosol tank is usually filled with liquid and compressed gas, and the pressure of the compressed gas forces the liquid to spray out through the outlet nozzle. When the nozzle button is pressed, the nozzle opens, causing the compressed gas and liquid to mix  and spray out. Inside the aerosol tank, the compressed gas usually exists in liquid form, and when the nozzle button is pressed, the liquid gas is quickly evaporated into a gaseous state, while forcing the liquid to spray out through the outlet nozzle. The fluidity of liquid is the key factor for its application in aerosol canister spray, and the choice of liquid has an important effect on the spray effect. In addition, the structure of the nozzle also plays a decisive role in the spray effect. For example, a nozzle with a porous core or a non-porous core can subdivide the ejected liquid into tiny fog particles, making the liquid more delicate and uniform after the ejected

There are four major components of an aerosol products, the aerosol can, the valve, the feed, and the ejector gas. Factors affecting the quality of aerosol cans, from raw materials, can-making equipment and processes to quality testing, there are many, the following is a brief introduction: 1、The quality of tinplate materials: Tinplate substrate for the manufacture of cans requires high purity, such as impurity content is too high, affecting the ductility, brittleness, hardness and other processing properties and corrosion resistance.The tinplate materials we use are of the highest quality, one of the best tinplate, the quality is guaranteed! 2、The quality of cans body welding and repainting: For tinplate cans, one of the weaker links is the weld, which requires strict mechanical properties. The welding machine used in our Sihai factory is the world famous Switzerland SOUDRONIC machine, the quality is guaranteed. 3、Leak detection: Aerosol products are mostly flammable and explosive products, each factory empty aerosol cans must be tested by online pressure leakage detection machine, and at the same time must be in accordance with the provisions of the deformation pressure and bursting pressure sampling, in order to ensure the safety of the product production, storage, transportation and use. Our Sihai factory not only has automated gas detection, but also manual hand inspection link, product safety can be assured. If you have any needs for the empty aerosol tin cans, please feel free to inquire, we will provide you with the best quality service.

Hazards When using aerosol cans, concern for safety is a top priority. Whether you are using an aerosol can indoors or outdoors, such as a pipeline, safety should be considered. There are three main hazards when using aerosol cans. 1. susceptibility to bursting Aerosol cans can remain safe if the can and valve remain intact. However, if the can is punctured, the valve malfunctions, corrodes, or is exposed to excessively high temperatures, the can will depressurize. In severe cases, the aerosol can may explode. 2. Toxicity and harmfulness Do you know what's in your aerosol can? Some aerosols contain hazardous substances, and workers must familiarize themselves with the SDS of the material. personal protective equipment or additional ventilation may be required. Ask the manufacturer for the SDS and read it carefully; determine if it is dangerous, hazardous, and choose a safe product. 3. Flammability Most aerosol can products and propellants are flammable, which can cause aerosol cans to become a fire hazard. Use away from open flames and heat sources. Storage of Aerosol Cans Aerosol cans should be stored in a dry area and not exposed to excessive temperatures. The pressure of an aerosol can increases with temperature. The internal temperature of the vehicle can rise to a high level when exposed to direct sunlight, therefore, aerosol cans should not be stored in the vehicle for long periods of time.
