In products such as electronics, automobiles, motors, instruments, electrical appliances, meters, home appliances and communications, 60%-80% of the parts are formed by molds. The high precision, high complexity, high consistency, high productivity and low consumption of parts produced by molds are unmatched by other manufacturing methods. There are many materials suitable for molds, among which 5 series and 6 series alloy aluminum plates are commonly used mold materials.
Customers generally have the following requirements for mold aluminum plates: firstly, the thickness tolerance of the plate surface is required to be small (generally positive tolerance), secondly, the hardness must meet the standard (HB is above a certain value), and then the deformation after processing should be small, and finally The flatness is better, and Mingtai can meet the needs of customers very well.
5052 alloy aluminum plate is a kind of anti-rust aluminum plate. Magnesium is the main alloying element in 5052 alloy aluminum plate. It has good formability, corrosion resistance, weldability and medium strength.
6061 aluminum alloy is a high-quality aluminum alloy product produced by heat treatment and pre-stretching process. Although its strength cannot be compared with 2XXX series or 7XXX series, it has many characteristics of magnesium and silicon alloys, good processing performance, excellent welding characteristics and Electroplating, good corrosion resistance, high toughness and no deformation after processing, dense material without defects and easy polishing, easy color film, excellent oxidation effect, etc.
What kind of material is healthy for cake molds? Generally speaking, anodized aluminum molds are the best. They are cheap and have no coating, which is not harmful to the body. Due to the good thermal conductivity of aluminum, the heat is evenly distributed, which is conducive to baking. From the perspective of the wide range of use, aluminum is used more. And strong and durable, not heavy and fragile like porcelain. Although there are silicone materials on the market, the silicone mold is soft and it is not easy to separate the pastry from the mold. Generally speaking, aluminum baking molds are better.
In addition to 6061 aluminum plates, there are also 5052 alloy aluminum plates and 7075 aluminum plates. Mingtai Aluminum can produce 5052 aluminum plates with a thickness of 0.3-500mm, and 7075 aluminum plates with a thickness of 20mm or more. Henan Mingtai Aluminum has many years of production experience.
The heat treatment technology is excellent, and the strength and hardness of the product are basically consistent when the thickness (diameter) is below 300 °C. High surface precision reduces material waste.
Minimize the deviation of chemical composition, strength and hardness, and eliminate the phenomenon of "sticking knife" and "knife breaking" during processing;
Perfect pre-stretching (T651) process, completely eliminate internal stress, not easy to warp, crack and deform during processing and stress.
The unique grain refinement process guarantees that there will be no sand holes, horizontal lines, bubbles and impurities;
There will be no permanent deformation under the working environment of 400°C.
