Advantages of zinc alloy car model OR disadvantages

In life, all the items have two sides of the value, or advantage is greater than the disadvantage, or disadvantage is greater than the advantage, but we can according to their different circumstances to give a reasonable use. Then the following to TT car model of the main push products - car model, for example, with the analysis.
Zinc alloy material advantages: (Such as: electroplating, spraying, surface polishing, grinding, etc.); melting and die-casting does not absorb iron, not the same, the casting performance is good, can die-casting complex shape, thin-walled precision parts, casting surface smooth; Corrosion pressure type, non-stick mold; have good mechanical properties at room temperature and wear resistance; low melting point, melting at 385 ℃, easy die-casting molding.
Zinc alloy material disadvantages: Zinc alloy car model die castings should not be used in high temperature and low temperature (0 ℃ below) working environment. Cracks can cause water lines, cold lines (metal liquid in the filling process, the first access to the metal liquid contact wall premature solidification, after the metal into the molten metal can not be merged into one, in the casting surface shallow; And cold stripes may penetrate into the casting), hot cracks, may also appear shrinkage, crystal corrosion and so on.
After reading the above, and zinc alloy advantages and disadvantages, no doubt zinc alloy material is suitable for the production of automotive models, more than the car model, aircraft model, ship model and other high simulation models are easy to control, and perfect presentation. How can the value of both sides and the two, you will.

Car model appreciation

The proportion is the most basic, different proportions of the production process and the number of spare parts are also very different. Followed by the details of the same static simulation of the car model , the details of the difference is enough to form a huge difference between the products, naturally also formed a huge difference between the price of the brand. How to go through the details to identify the quality of the car model quality and grade of the level of the following methods can let you have a basic way to identify: weigh the weight, guess parts, paint, knowledge, see the door, listen to the sound, Check the details, gaps, lights and windows, chassis, engine, interior, tires and wheels, etc., these methods look nothing, when you actually will find one of the differences, I think there should be a lot of friends Has been doing it! During the period do not understand or want to know the specific content, you can give me a message! Finally, we talk about auth...

Car model drawings

Car models are divided into 2D drawings and 3D drawings. 2D drawings: simply 2D is a linear plane diagram, there is a line to the vehicle shape, interior details, tires and other sketches out, just like the painting of the same picture, but the 2D linear chart of each line are with Data, so when drawing 3D drawings, if the import 2D map, the designer can be based on these lines of data to describe the design. Although it still takes some time, but compared to pure picture reference design, whether it is time or simulation accuracy is much higher. 3D drawings: Tong Tong model is generally used PROE software for 3D design, 3D design, also known as three-dimensional design, is a new generation of digital, virtual, intelligent design platform based. He is based on the plane and two-dimensional design on the basis of the design goal more three-dimensional, more visualized a new design method, just like a 3D movie is a meaning. When the customer can provide the 3D map to t...
