Requirements for accuracy of prototype model making

when chatting with customers, they all ask how accurate our prototype model is? Why do most users who need to make prototypes ask this, mainly because the higher the accuracy of the prototype model, the smaller the gap with the actual product, and the more real the detection results are, it is also more conducive to opening the mold.

Everyone must know that the accuracy of the prototype is higher, and there is still a certain gap with the physical object. Generally, when making the prototype, accuracy can be controlled at positive and negative 0. 1mm words (That's ten Silk) There is no problem in making a general prototype model. The equipment used by our company is relatively good, and the accuracy can reach 0. 05 ~ 0. 1mm, generally the smaller things the higher the accuracy.

especially in the medical industry, the requirements of medical devices are different from others, the requirements for accuracy are extremely strict. We often do the appearance of medical White paint, but also need UV effect, material ABS or UV light oil can be done, screw holes need to be buried nuts, nuts must be firm. In this case, if the price is reasonable and the quality is no problem, customers will generally cooperate with us for a long time.

products with high precision like this, if there is a problem with the quality of complex model estimation, it is generally difficult to reach positive and negative 0. 1mm, so that the requirements of the test assembly can not be met. If you do it in batches, the CNC machining cost is high and it is not cost-effective. The medical equipment we make for other customers is done in the form of multiple models. CNC processes the prototype first, and then copies dozens of sets in batches.

In short, if the accuracy of the prototype model you need to make is not very high, a complex model can be adopted, but if the accuracy requirements are high, it is better to use cnc machining.
