We all know that the cold storage door is quite heavy for a cold storage, if there is no choice of good cold storage door, then the freezing effect of the cold storage can not reach the ideal state. So if you want to produce a good cold storage door, the material must be used to be able to support the normal operation for a long time, the next small series will introduce the materials used in the manufacture of cold storage door and related classification.

So if you want to produce a good cold storage door, the materials used should be able to support the normal operation for a long time, the next small series will introduce the materials used in the manufacture of cold storage doors and related classification.
At present, the cold storage doors sold on the market are mostly made of high-strength aluminum alloy materials. The door frame made of aluminum alloy has very high strength and will not deform. It is very beautiful and durable from the outside. At the same time in the cold storage door around the use of two centimeters of stainless steel edge seamless welding material, this material is durable, the structure is quite reasonable. In the interior of the door leaf of the cold storage door, polyurethane pressure injection machine is generally used to inject foam into the door. After the foaming material is formed, it is relatively dense and can be evenly punched. The phenomenon of cold expansion and heat contraction will not occur in various places of the cold storage door, making the door face more smooth and beautiful, and at the same time having the effect of warm heat insulation.
The guide rails of cold storage doors are mostly made of high-strength anti-rust aluminum alloy materials for press forming in the factory, while the inside of the cold storage doors adopts a floating wall door opening system. When the cold storage doors are opened, the sealed rubber strip will reduce the friction force of the aluminum alloy door frame. When closing, due to its own weight, the door frame will be completely sealed in a relatively easy way. The hardware or other parts used in the cold storage door are all made of stainless steel, and precision instruments are used in the factory to make the precision higher, the appearance looks beautiful and generous, and the use for a long time will not cause its wear, making it more light and flexible when switching, and it is also very convenient when installing.
The sealing strip adopts TPE environmental protection sealing strip, which makes the sealing performance and service performance of the cold storage door become more good. Two sets of heating antifreeze equipment are installed on the door frame of the cold storage door and the door frame, which effectively prevents the freezing of the combination of the cold storage door and the door frame. If someone is accidentally locked in the cold storage, only need to pull the inner ring out, to avoid the occurrence of security risks.
