Thanks to the rich colors, light weight, easy processing and no rust, the color coated aluminum strip is ideal for for gable and valley constructions, chimney and roof window flashings, dormer cladding, shutter, ceiling, household appliances, aluminum cans,roller shutters,etc.During the manufacturing process, the coating kinds, thickness, pattern and hardness all can be customized according to the customers’ requirements. There are two commonly used coatings: polyester (PE) coated aluminum strip and fluorocarbon (PVDF) coated aluminum strip. There are cases where one side is coated with fluorocarbon and the other side is coated with polyester or both sides are coated with PVDF coating.According to the coating thickness, the coated and embossed aluminum strip can be divided into single coating (4-20 microns), double coating (25-28 microns) and 3 coatings (35-38 microns). Then how to control its harness? It is a little complex question. Lets have a look together.1. Setting and control of aluminum aging furnace temperature: Generally, there is a certain error between the aging furnace temperature and the apparent temperature of the aging furnace. The setting of the apparent temperature should be according to the actual temperature of the furnace.2. Aging and heat preservation of colour aluminum strip: Aging should be carried out in strict accordance with the process requirements, and the heat preservation time should be appropriate to prevent under-ageing or over-ageing from causing insufficient hardness.With our experienced workers and advanced equipment, Haomei Aluminum can offer you quality coated and embossed aluminium strip. We support sample test. Welcome to leave message below to inquire the aluminum strip price.

Ceramic PCB is relatively stable, and it is not easy to deform under high temperature and humidity environment, but the price is relatively expensive and fragile, which is often used in high-end products. But for the common goods such as LED light panels, is there a PCB substrate with cheap material and good heat dissipation?The answer is aluminum sheet for PCB. As we all know, aluminum is a kind of metal and has conductivity. How can it be used as a PCB material? This is because the aluminum substrate consists of a three-layer structure: copper foil, insulating layer and metal aluminum. Since there is an insulating layer, can the metal layer be made of other materials besides aluminum? Such as copper plate, stainless steel, iron plate, silicon steel plate, etc.In addition to the heat dissipation performance, the thermal expansion coefficient, thermal conductivity, strength, hardness, weight, surface condition and cost of the metal substrate must also be considered. Considering the cost and technical performance, aluminum drilling entry sheet is an ideal choice. Available aluminum plates are 6061, 5052, 1060, etc.The aluminium drilling entry sheet is commmonly used in LED lighting products. It has two sides: the white side is soldered with LED pins, and the other side is in the natural color of aluminum that is coated with the thermal conductive paste.Its other main applications includes:Lighting products: High-power LED lighting products.Audio equipment: Preamplifier, power amplifier, etc.Power equipment: DC/AC converter,solid state relay,etc.Communication products: High-frequency amplifiers, filter appliances, and transmission circuits.As a big aluminum sheet supplier, Haomei Aluminum has rich specifications of alu sheet for PCB.

| Cold Forming Blister Foil Pharmaceutical Packaging |

The blister packaging of medicines consists of aluminum foil and PVC rigid sheet. However, with the continuous development of the pharmaceutical industry, this traditional packaging method has exposed its shortcomings: due to the limited barrier properties of PVC rigid sheets, it is difficult to ensure that the quality of the medicines will not change during their service life.In response to the limited barrier properties of ordinary blister packaging, people have developed cold forming rigid sheets to replace the the vacuum blister forming, so that the cold forming blister foil can be used as as the blister forming material.The use of high-strength aluminum foil in cold-stamping makes the cold-stamping hard sheets have extremely high water vapor, oxygen and light barrier properties that cannot be achieved by any other material.The cold-stamping hard sheet is generally composed of three functional layers: the surface supporting strength layer, the middle aluminum foil barrier layer, and the inner surface heat sealing layer. The surface layer can be printed with the color or pattern required by the customer, and the layers are bonded together to form a composite film as a whole(as shown in the picture).The blister foil used in cold stamping not only performs the barrier function, but also has the functions of strength support, and stamping and stretching resistance, so it is different from the general flexible packaging composite aluminum foil. It needs to be of extremely high strength and good extensibility.Since the cold forming needs to be stamped, the thickness of the aluminum foil used is much thicker than that of the ordinary composite film. Generally, 45μm thick aluminum foil is used. For the shallow stamping, the aluminum foil thickness is reduced to 30μm. For applications where the punched bubble is particularly deep (≥15mm), the maximum thickness can be increased to 70μm.The pharmaceutical aluminum foil for cold forming is 8021-O and 8279-O aluminum foil with a thickness of 0.025-0.08mm. The 8021 and 8079 aluminum foil produced by Haomei Aluminum , have high cupping value, high heat seal strength, no pinholes and good air tightness. Haomei Aluminum has been a long-term cold forming blister foil supplier for various medical packaging companies at home and abroad.

With more then 100 hundred years’ development, the aluminum foil packaging has finally completed its transformation from aristocratic packaging to civilian packaging. In the early 20th century, due to the limitation of aluminum smelting technology, the output of aluminum foil was extremely scarce, and aluminum foil naturally became the most expensive packaging material at that time.In 1911, a Swiss candy company made a decision: use aluminum foil to to replace the original packaging of chocolate. It was because of this decision that aluminum foil attracted a lot of attentions.In the following 20 to 30 years, the development of aluminum foil packaging has been relatively stable. During World War II, packaging aluminum foil has got a more rapid development. At that time, with its excellent barrier properties and extensibility, aluminum foil as a military packaging material developed rapidly.In the 1950s, aluminum paper and aluminum-plastic composite materials began to appear, and the practicality of aluminum foil has been further developed. In the 1970s, the continuous maturity of color printing technology has made the appearance of aluminum foil more attractive.In the 21st century, the increasingly popular aluminum foil packaging has shown a trend of market competition, which has also stimulated the upgrading of packaging aluminum foil materials to a certain extent. There are rich types of aluminum foil paper widely used in many fields such as household foil, aluminum foil for pharmaceutical foil, food aluminum foil, air conditioner foil, tobacco foil, etc. Welcome to leave message below to inquire the aluminum foil you need.

The processing craft of aluminum sheets in different fields are not same. After treatment, the aluminum sheets have higher strength, hardness and elongation. The hot rolling and cold rolling are the commonly used treatment processes.The features of the hot rolled aluminum sheet: In the process of deformation,the internal structure has undergone multiple recovery and recrystallization, the casting defects has been significantly improved, thus improving its processing performance. Especially in terms of deep drawing performance, the hot rolled aluminum has incomparable advantages over cast-rolled materials.The production process of aluminum plate includes hot rolling, casting rolling, casting, etc. Among them, the performance of hot rolling aluminum plate in stretching and anodizing is better than aluminum plate produced by other processes. In addition, the equipment cost and production cost of the hot-rolled aluminnum sheet are relatively high.During the use of aluminum plates, they may undergo further processing such as stretching, bending, stamping, cutting,etc. Generally, the stretched aluminum sheet should not be too hard. Therefore, the elongation and tensile strength of the aluminum sheet will have different requirements according to the stretching height and the stretching method. Both cast-rolled and hot-rolled sheets can be used for stretching, but the effect of cast-rolled sheets is not ideal.The cold rolled aluminum sheet is cast-rolled coil. Then it will be processed by the cold rolling mill into the cold rolled alumimum. As the cold work hardening caused by continuous cold deformation increases the strength and hardness of the rolled hard coil, and decrease the ductility and stamping performance, it can only be used for simple deformation parts such as molds.As an aluminum plate supplier, Haomei Aluminum has both hot rolled and cold rolled aluminum sheet.
