Experienced prototyping masters know that the selection of prototyping materials is very important. If the selected material is not good enough, the performance of the researched prototyping will not be much better. In order to let everyone know the material requirements for prototyping, Shenzhen Xiehe prototyping factory will share with you the conditions that need to be met for prototyping and material selection. Let‘s take a look.
1. Strong toughness
During the long-term action of cyclic stress, the prototype needs to withstand multiple impacts and has a large impact load, which is easy to cause fracture. Therefore, in order to prevent the prototype parts from breaking suddenly during work, the prototype should have high strength and toughness. The toughness of the prototype mainly depends on the carbon content, grain size, microstructure, and inclusion content and strength of the material.
2. Wear resistance
The wear resistance of the material is one of the most basic and important properties of the prototype. Hardness is the main factor affecting wear resistance. Generally speaking, the higher the hardness of the prototype parts, the smaller the amount of wear and the better the wear resistance. In addition, wear resistance is also related to the type, quantity, shape, size and distribution of carbides in the material.
3. High temperature performance
When the working temperature of the prototype increases, the hardness and strength will decrease, resulting in early wear or plastic deformation of the prototype and failure. Therefore, the prototype material should have high tempering resistance to ensure that the prototype has high hardness and strength at working temperature.
4. Corrosion resistance
When some prototypes such as plastic molds are working, due to the presence of chlorine, fluorine and other elements in the plastic, strong corrosive gases such as HCI and HF are decomposed after heating, which will erode the surface of the prototype cavity, increase the surface roughness and aggravate wear. invalid.
5. Heat and cold fatigue resistance
Some prototypes will be in a state of repeated heating and cooling during the working process, so that the surface of the cavity is likely to cause surface cracking and peeling, thereby increasing friction, hindering plastic deformation, reducing dimensional accuracy, and ultimately leading to failure of the prototype. Hot and cold fatigue is one of the main forms of failure of hot working prototypes, and such prototypes should have high resistance to cold and heat fatigue.
The above is an introduction to the conditions that need to be met for the selection of materials for rapid prototype processing. I hope it will be helpful to everyone. Nowadays, there are many prototyping factories in Shenzhen. When choosing, you must learn to distinguish the reputation of the manufacturer from bad and the strength, so as to avoid unqualified prototyping. Shenzhen Xiehe Prototype Processing Factory has been focusing on prototype production for many years and has rich experience.
