According to the manufacturer of handboard model, the prototype sometimes encounters many changes in the manufacturing process of handboard. For example, due to excessive external force, temperature, natural environment and other factors, the prototype model will crack or deform!

為了防止這種情況，有必要從多方面把握原型模型的裂縫和變形，多方面防范，手板模型發生裂縫大部分是由于內部的應力縫隙超過手板模型的承受能力時，當手板模型產生裂縫，這是一個不能挽救的損害，要盡可能的去防止。手板模型內部的應力會使手板模型受壓不勻稱，手板模型則會產生變形！
             

In order to prevent this situation, it is necessary to grasp the cracks and deformation of the prototype model from many aspects, and prevent them from happening in many ways. Most of the cracks in the hand board model are due to the internal stress gap exceeding the bearing capacity of the hand board model. When the hand board model has cracks, it is an irreparable damage, which should be prevented as far as possible. The stress inside the model will make the model pressed unevenly, and the model will deform!

在制作手板模型的整個過程中，必 須有經驗豐富的手板廠家來更好地解決手板模型的應力和其他導致手板模型變形的因素，并改善手板結構！

In the whole process of making the model, we must have experienced manufacturers to better solve the stress of the model and other factors leading to the deformation of the model, and improve the structure of the model!
