Can silicone copy fingerprint to hit attendance?Of course, but the requirements of silica gel are particularly high, ordinary silica gel is unable to meet the fingerprint punch card.

  First of all, we need to understand the punch machine is belong to which kind of type, different types of punching machine is different to the requirement of silica gel, simply punch machine is divided into two one is fused punch machine, another for light feeling punch machine, fused punch machine need silicone fingerprints can be replicated, not just need silica gel can be conductive, can identify fingerprint puncher;Photosensitive punch-cards do not need silicone to conduct electricity, as long as they can replicate accurate fingerprints.

  Whether it is light sense puncher or electric melt puncher, in addition to the difference between conductive, other requirements are the same.The operational requirements of silica gel are relatively high, and silica gel needs to complete the operation in a very short time. Ordinary silica gel cannot meet this requirement, and it must be replaced by formula and raw materials to achieve this speed.It also says that silica gel needs to be operated quickly when operating the ratio, otherwise the silica gel will not be able to operate. Specifically, you can ask Hongtu silica gel, who is a professional manufacturer of liquid silica gel.In addition to the operation, there is a strong replication performance of silica gel, which can perfectly copy the fine fingerprint on the hand, so as to improve the identification rate of fingerprint. At present, there are few products on the market that can produce this material, and the more precise the replication texture of silica gel is the higher the cost.The precision or directness of the copied texture affects the recognition rate of the punch card.In addition to the fingerprint puncher silicone operation process and fine pattern replication and the physical properties of the silicone itself is also require higher, such as our common elongation, tear strength, tensile strength, these requirements are relatively high, if not these performance, then make good silicone fingerprint puncher, probably in the process of storage or transport damaged, Lead to a good copy of the fingerprint is affected, the recognition rate is reduced or even can not pass;Make good silicone fingerprints, also don't get that to use immediately, because the silica gel from a liquid into a solid process, if the silicone is not completely cured to use this for a while cause the original copy of fingerprint distortion, undermining the fingerprint, as to how long can consult future silica gel, which is a professional manufacturer of liquid silicone.

  So to sum up, the silica gel can copy the fingerprint punch card attendance.Not only can copy fingerprint puncher, but also more copies of the fine texture, such as palmprint, our bodies and our texture with blood on hand, can be copied, is particularly high fidelity, of course, different USES and process requirement for silicone is different, make the human body, make the material of artificial limb with fingerprint puncher to process is not the same.
