What are the common methods of hand model making? Next, the Xiehe prototype processing factory will give you a brief introduction.

There are several common methods for making prototype models:

1. CNC fast prototype (hardware, plastic prototype):

CNC hand-board model making is a traditional processing method that cuts off the excess material of the blank to obtain the required prototype. From a technical point of view, it is a combination of advanced technologies such as computer-aided design (CAD), computer-aided manufacturing (CAM), and computer numerical control (CNC). A processing method formed. In the prototype industry, CNC processing is generally aimed at the shell structure and solid appearance board of some larger workpieces, and can also make some structural parts for functional testing. It has a wide range of processing materials.

CNC prototype model production process: accept drawings→write tool path→transmit tool path to CNC machining center→machine automatic processing→manual post-processing (grinding, painting, printing, etc.)!

2. Vacuum injection (silicone compound mold) prototype:

That is to use the original model to make a silicone mold in a vacuum state, and use PU material to cast it in a vacuum state, so as to clone the same replica as the original model. Due to its high speed and low cost, this technology greatly reduces the product development cost, cycle and risk.

3. SLA laser rapid prototyping prototype:

Rapid prototyping technology is integrated and developed on the basis of modern CAD/CAM technology, laser technology, computer numerical control technology, precision servo drive technology and new material technology. Different types of rapid prototyping systems have different forming principles and system characteristics due to the different forming materials used. However, the basic principles are the same, that is, "manufacturing layer by layer, superimposing layer by layer", which is similar to the integral process in mathematics. Visually speaking, the rapid prototyping system is like a "three-dimensional printer".

The above content is a few common methods of making prototype models, and I hope it can be helpful to everyone. If you want to know more about hand processing, please call Xiehe hand processing factory, we will serve you wholeheartedly.
