Tin can making machine price? China tin can making machine price in 2020?

To understand the price of canning equipment, first we need to know what specific canning equipment is required for a complete canning production line. Let us briefly understand the specific equipment.

Three-piece can production line equipment classification: Three-piece can production line manufacturing equipment is divided into cutting equipment, forming welding equipment, drying equipment, rolling equipment, slitting equipment, necking equipment, embossing molding equipment, turning equipment Side equipment, capping equipment, can sealing equipment, leak detection equipment, full internal spray equipment, drying equipment, stacking equipment, packing, etc.

 

  1. Empty can preparation equipment mainly includes: cutting equipment, parting equipment, coating scraping equipment

① Cutting board equipment is used to cut the large sheet of tinplate into pieces of the size required for canning or punching. Its process flow is as follows:

Feeding and cutting → finishing

② Scribing equipment is a device for scoring the uncoiling line or slitting line on the can body blank. Its role is to draw a trace of a certain depth on the cut can body material in order to separate the finished can body from the scribe line.The process is as follows:

Feeder → Single sheet feeding and feeding → marking → selection

Scribing equipment is available in automatic or semi-automatic stand-alone form, as well as in combination with can body welding and forming machines.

③ The coating layer scraping equipment is used to partially scrape the surface coating of the cut can body sheet to facilitate resistance welding (the equipment is not needed to leave the paint plate empty). The process flow is as follows:

Feeder → Single sheet feeding→ Scraping → Stacking

The price of the preparation equipment is about: USD10000-70000

 

2. Can body forming welding equipment

Classification of can body forming welding equipment

The price of can body forming and welding equipment is about:USD10000-50000

 

3. Can embossing and expansion equipment

(1) The characteristics of embossing and expansion of the tank The embossing or expansion of the tank can be changed to various cross-sectional (longitudinal or cross-sectional) shapes.

This pot is a fancy pot. Patterned cans can be divided into two types: one is round, which is characterized in that the mouth shape of the lid maintains the original shape of the round can, and the middle part of the can can be changed according to the shape of the user’s requirements, such as barrel shape, drum shape, Vase-shaped, square, polygonal, cone-shaped, etc., this kind of pot is called an embossed pot (formed fancy pot); another shape of the pot is a special shape, which is characterized in that the lid is non-circular, and the pot body and The shape of the lid is basically the same. Common canned food types are: square, rectangle, polygon, trapezoid, pear (horseshoe), oblate, oval, etc. These cans are called irregular cans.

During the expansion process, the formed tank body is slightly stretched, and the stress on the metal reaches the elastic limit of the material. Before resistance welding occurs, the expansion process of the formed tank cannot withstand such a large expansion force, so the formed shape is not flat. The main body of the embossing tank has a large tensile force, and the stress on the metal exceeds the elastic limit of the material, and large tensile deformation occurs. Compared with the original tank, the volume of the tank after embossing can be increased by about 20%. Since both embossed cans and new-shaped cans need to withstand greater expansion force, only welds (such as resistance welding, laser welding, etc.) can meet the expansion requirements. Because the middle part of the embossed tank has a large tensile deformation, there are higher requirements for the coating on the outer surface and the inner side of the printed iron to prevent damage to the printing and coating caused by such deformation. In addition to the expansion method after welding, there is also a bending method before welding. This method is often used in the welding process of tanks. The tank is directly pressed into a special shape and then welded.

The price of can embossing and expansion equipment is about:USD20000-80000

 

Fourth, repair coating equipment

Repair coating equipment is a kind of equipment covering a layer of protective layer on the weld, the protective layer will not damage the content and have corrosion resistance. After welding, there is no tin layer on the weld, and the inner and outer welds are in direct contact with the inclusions or the atmosphere, which is easy to rust, especially the high-content acid and sulfur of canned food that has been processed at high temperatures and can be stored for a long time. There are more stringent requirements, so internal and external welds must be repainted. The recoater equipment consists of a cam body transmission system and a recoater system. The tank conveying system usually has two electromagnetic conveyor belts, which can continuously, smoothly and accurately send the tank into and out of the coating area after welding.

Coating equipment is roughly divided into the following categories:

The price of recoating equipment is approximately:USD5000-20000

 

Five, drying equipment

The coating on the tank must be cured by heating to volatilize the solvent, thereby polymerizing the monomer and obtaining anti-corrosion properties.

Especially for high-temperature sterilized food, its curing requirements are higher. During curing, the temperature of the surface of the tank must not be higher than the melting point of tin, and the coating must not blister or burn. The curing time must be sufficient. The drying equipment consists of a tank conveying system and a heating system. The conveying system usually uses chains, steel belts or belts, etc., with the help of magnetic adsorption, to send the tank into and out of the heating zone. The conveying system is divided into linear conveying and circular conveying, saving space.

The price of drying equipment is approximately:USD5000-15000

 

6. Equipment that can be rolled and typed

The function of tank rolling ribs and separation equipment is to roll reinforcing ribs on the welded tank or to cut the tank into two or three sections. A roll-bead slitting machine cannot complete these two processes at the same time. If necessary, please replace the rolling rib mold or split mold and configure it as a rolling rib splitter or mold splitter. Some assembly machines have multiple stations, which can be equipped with different molds at the same time to complete processes such as beading, parting, flanging, and sealing, and the principles are the same.

The price of can body rolling and separation equipment is approximately:USD8000-30000

Seven, can shrink, flanging equipment

(1) The necking machine reduces the diameter of the end of the tank, which can reduce the material consumption of the tank cover, which is beneficial to the stacking and transportation of the tank.

nice appearance. Constriction is divided into ordinary single necking, large single necking, two necking, three necking, four necking and so on.

The necking method is divided into rolling method and shrinking method. The rolling method is pure rolling in which the inner and outer molds are rotated while feeding in the radial direction. The thin-iron necking and flanging thin necking method can be completed at the same time when winding, which is easy to wrinkle. The shrinking method is directly extruded by opening and closing the inner mold and the outer mold with a cone, and is formed in one operation. Multiple necking requirements are adopted: uniform necking, smooth, no wrinkles, no oxide film and coating peeling at the weld seam of the tank body, no mechanical wiper or multiple stations to perform a single contraction on the inner and outer surfaces of the tank body The can body, the second shrinkable can, three shrinkable cans, and four shrinkable cans.

(2) Flanging machine: Flanging machine is a device that prepares the wound and necking process by squeezing the flanging mold to clean the two ends of the tank to the edges of the required shape and size. Flanging methods are divided into crushing type, rolling type, rotating type and plate edge type. The extrusion flanging uses a flanging die to extend from both ends, and hits the edges of the two ends of the can along the axial direction of the can body, thereby forming flanges at both ends of the can body. Flanging and necking are done at the same time. The principle is the same as the rolling neck. There are two types of rotary flanging: one is the active rotation of the flanging roller, which has various forms; the other is the driving rotation of the flanging roller, and the two motion principles are the same. The flanging die is composed of multiple flanging rollers. The flanging die extends from both ends of the tank body and is fed along the axial direction of the tank body while rotating. Squeeze both ends of the tank to gradually complete the flanging. The flange beads are arranged along the circumference according to certain rules. The larger the tank diameter, the more flanging rolls, and the deformation is uniform and slow. Therefore, the flanging quality is good, which is especially suitable for the flanging of high-speed thin tin cans. Flanging type flanging is used for flanging special-shaped cans. The outer mold fixes the tank, and the inner mold moves from the inside to the outside to complete the flanging. The flanging die is composed of multiple flanging rollers.

(-) Coating purpose and requirements

Tinned plate, chrome plated and aluminum alloy thin plate made of cans are susceptible to corrosion and cause the contents to deteriorate. Therefore, most food cans require coatings inside the cans. Different food cans have different coating requirements.

  1. Purpose of coating

(1) Protein-rich aquatic products, poultry and meat cans use anti-sulfur coatings to prevent sulfidation corrosion caused by thermal decomposition of proteins, such as vulcanization spots and iron sulfide.

(2) The acidic tomato sauce and pickled cucumber adopt acid-resistant paint to prevent acid corrosion of the cans and ensure that the canned food has a certain shelf life.

(3) Certain anthocyanin-containing fruits, such as strawberries, cherries, and bayberry, use general coating material to prevent anthocyanins from corroding cans and contents from fading due to tin reduction

 

(4) Steamed fish and luncheon meat are easy to stick to the cans. The coating containing anti-sticking agent makes the contents easy to pour out and keep the shape complete and beautiful.

(6) Canned beer coating material is (spraying after weaving) to eliminate pores and prevent iron ions from dissolving, which affects the flavor and transparency of beer.

  1. Coating requirements

(1) The coating should be non-toxic after film formation, without affecting the flavor and color of the contents.

(2) After the coating film is formed, it can effectively prevent the contents from corroding the cans.

(3) The coating has good adhesion after film formation, has the required hardness, punch resistance and solder heat resistance, etc., which can meet the requirements of can making process.

(4) After sterilization of the canned product, the coating film will not change color, soften and fall off.

(5) Convenient construction, simple operation, and a good coating film can be formed after drying.

(6) The coating material and solvent price are cheap.

(7) The coating material has good storage stability.

Tips for making tinplate lids

Tips for making tinplate lids
The selection of can lids making equipment should first consider product specifications, output scale, quality requirements, followed by is equipment costs, labor costs, operating costs, plant conditions and other factors.
Generally speaking, for the production of metal covers with few specifications and varieties, large output, and high quality requirements, equipment with high production efficiency and high degree of automation should be selected, such as various types of multi-function combined machines configured as automatic production lines. Due to the small specifications, it is not necessary to change molds and debugging equipment frequently, and it is easy to take advantage of the large-scale production of high-speed automatic production lines to avoid the damage caused by the handling of semi-finished products in the semi-automatic production process. At present, more advanced lid-making equipment can be provided in China, such as corrugated plate shearing machine, double-head automatic punching machine, glue injection drying combined machine, etc. For the production of special-shaped lids with quality requirements, it is best to choose a full lids curl machine to improve the sealing quality. The small size special-shaped cover can be directly selected the automatic curl & glue lining combined machine.The large-size special-shaped cover lining machine is relatively in low production speed. So, For large-size lids lining can use multi-gun semi-automatic lining machine or automatic lining machine. The dryer can be preferred to use a vertical dryer, and its drying quality is better than that of tunnel dryer. For products with many specifications and a lack of large quantity demand, and the production of metal covers with general quality requirements, you can consider choosing multiple semi-automatic stand-alone equipment.On the one hand, you can reduce the number of mold replacements and machine adjustments.On the other hand, you can also reduce the equipment. Investment costs. The rounded edge of the special-shaped cover can be considered to use half-curl or full-curl. As far as possible, the glue injection should not use the printing glue that is facing elimination. The tunnel dryer is suitable for any size and shape of metal cover, but it covers a large area and has high energy consumption. The drying quality is not as good as the vertical dryer, and it needs manual loading and unloading. The aluminum easy-open cover has fewer varieties and specifications, but the output is extremely large, so it requires a high-speed large-scale automatic production line, which is not yet available in China. The current demand for tinplate full opening is relatively small. The production capacity of domestic production lines has reached more than 80 pieces / min. The product quality also meets the requirements for use. Compared with similar foreign products, the price is low and should be preferred.

What is the price of aluminum beverage can? What is the difference between aluminum beverage can and tin can?

When it comes to packaging, people have given different connotations. In the past, people thought that packaging was the use of appliances to contain items, or the operation of wrapping and bundling items, which merely played a role of accommodating items and facilitating access. This understanding is obviously one-sided. Now people have given a broader meaning to packaging. From a systemic point of view, it links the purpose, requirements, constituent elements, functions, and practical operations of packaging to form a complete concept.

 

The use of aluminum packaging materials has a short history, but because aluminum has its own unique characteristics, it has gradually increased as a food packaging material. The amount of aluminum used in aluminum foils, tubes and containers in China accounts for 2% of aluminum production. The main properties of aluminum are light weight, non-toxic, tasteless, beautiful, good processing performance, and shiny surface. In addition, because a dense alumina film can be formed on the surface of aluminum, it can effectively isolate the contact between aluminum and oxygen, and prevent further oxidation of the aluminum surface. However, it is corrosive in acid and alkali salt media, so almost all aluminum containers are used after spraying. Its strength is lower than steel, and its production cost is higher than steel, which is about five times that of steel. Therefore, aluminum is mainly used for sales packaging. For example, aluminum cans are mainly used for packaging of aerated drinks with a certain internal pressure. A small amount is used for transportation packaging.

What is the difference between aluminum beverage can and tin can?

Iron cans and aluminum cans are currently widely used, each with its own advantages.Z、 However, the current market for tin cans is more popular and advantageous.

The cans are made of aluminum alloy, and the inner wall is coated with some organic coating to isolate the aluminum alloy from the beverage. During the processing, it is inevitable that the protective coating is not applied or is too thin, so that the aluminum alloy on the inner wall of the can comes into contact with the beverage. The aluminum element gradually dissolves in it, especially when the can is filled with acidic or alkaline beverages.

Canned beverages should not be used often and often, especially children with strong growth and poor elderly excretory function, it is better to drink less. Refining aluminum cans can cause pollution. Aluminum cans are passivated and cannot be dissolved by ordinary weak acids.

Aluminum cans are generally coated with a protective layer on the inner wall. Acid substances generally do not erode aluminum cans during the shelf life, but if the shelf life has passed, it may not be necessary. If it is stored for too long, an acidic substance reacts with aluminum to cause aluminum ions to enter the beverage in large quantities. Aluminum will accumulate too much in the body, which will cause Alzheimer’s disease.
