What details should CNC prototype model manufacturers pay attention to? 2021-05-02 15:28:02
1. Conventional products are usually made of ABS material, which is easy to process and beautiful in post-processing.

2. High temperature resistant products, optional materials

(1) Epoxy resin;

(2) Bakelite;

(3) Black PC;

(4) PA (nylon).

In addition to the black PC, the other three kinds of handboards made of these four materials can not be bonded and need to be processed as a whole.

3. Wear resistant products: POM or PA can be selected. These two kinds of materials can not be bonded, need to be processed as a whole.

4. For high toughness products, PA or PP can be selected. These two kinds of materials can not be bonded, need to be processed as a whole.

5. Transparent products can be made of PMMA (acrylic), transparent ABS, transparent PC and other materials. The handboards made of these materials are highly transparent through polishing, achieving the same effect as real products.

6. The surface treatment of product hand plate is generally divided into oil spraying, electroplating, frosting, silk screen printing, pad printing and other surface effects. Hand spray is divided into smooth surface, dumb surface, sand surface, transparent color, translucent color, fluorescent color, rubber oil and other effects.
The quality of prototype and stamping and its influencing factors 2021-05-02 15:29:36
What is quality? Quality is divided into process quality and production quality. Process quality refers to the process plan that meets the quality requirements of qualified products; Production quality refers to the production capacity with quality in the production process. Because most of the domestic manufacturing enterprises are small and medium-sized enterprises, and a considerable part of them are still in the traditional workshop type production management stage, often ignoring the quality of the hand board, resulting in a long development cycle and high manufacturing cost, which seriously restricts the pace of development of enterprises.

First let's take a look at the main factors that affect the quality of handboard and stamping, which are: the use of handboard materials; The strength requirements of hand board structure; Quality of stamping material performance; The fluctuation characteristics of material thickness; The change range of materials; The resistance of the tensile bar is small; The variation range of blank holder force; Selection of lubricants.

Comprehensively weigh the factors that affect the quality of the hand board. It is worth noting that in the stamping process, because each stamping sheet has its own chemical composition, mechanical properties and characteristic values closely related to stamping properties, the instability of stamping material properties, the fluctuation of stamping material thickness and the change of stamping material not only directly affect the accuracy and quality of stamping processing, It may also cause damage to the hand board.

Take drawbead as an example, it plays a very important role in stamping. In the process of stretch forming, the forming of products needs to have a certain size of tensile force which is properly distributed along the fixed periphery. The tensile force comes from the force of stamping equipment, the deformation resistance of edge part materials, and the flow resistance on the blank holder surface. If the flow resistance only depends on the blank holder force, the friction between the hand plate and the material is not enough. For this reason, it is necessary to set tensile bars on the blank holder to increase the feed resistance, so as to make the material produce greater plastic deformation, so as to meet the requirements of plastic deformation and plastic flow. At the same time, by changing the size and distribution of the drawbead resistance, and controlling the material flow speed and feeding amount to the hand plate, the effective adjustment of the tensile force and its distribution in each deformation area of the drawing part can be realized, so as to prevent the product from cracking, wrinkling, deformation and other quality problems. It can be seen from the above that in the process of making the stamping process and the design of the hand plate, the tensile resistance must be taken into account. According to the variation range of the blank holder force, the draw bar should be arranged and the form of the draw bar should be determined, so that each deformation area can complete the forming according to the required deformation mode and degree.
What are the advantages of the plastic model compared with other models 2021-05-02 15:31:14
Dongguan new power plastic hand plate is also a model processed by CNC machine tools. Here, we need to make clear the concept of hand model and plastic hand. Let's take a look at the model. The so-called handboard model, also known as the first version model, is the first version of the trial production of the product. Generally, it is a prototype product, which is used by designers to detect whether their products have defects in shape design or structure. There are some products that can't see defects on the design drawings, but can't be used or even produced. Therefore, we must first make handboards.

The plastic hand board is the abbreviation of numerical control technology, now in industrial manufacturing above the general index control machine tool. Numerical control machine tool is different from traditional manual machine tool and fitter. As long as we input corresponding parameters on the machine tool, we can command the machine to process raw materials into corresponding products. And the processing speed and precision are very high. Now some of the more advanced CNC machine tools can be directly imported into CAD drawings for production. Only need to import the drawing, soon, the machine can automatically produce the corresponding products, and do exactly, very convenient.

It can be seen that Dongguan new power plastic hand model is characterized by fast production speed, high precision, convenience and reliability, which can liberate the hands of engineers and designers. After designers design their own products, as long as they input the drawings into the CNC machine tools, they can quickly get the prototype products for analysis, instead of waiting three or five days to get the model as before, which greatly delays the evaluation time. Moreover, the restoration of the design drawings by the machine is absolutely true, and there is no need to worry about the inconsistency between the model and the design drawings.

However, Dongguan new power plastic hand model also has its disadvantages, that is, the cost is relatively expensive. Because an advanced CNC machine is expensive. Of course, it's not cheap to use it once. However, if it is for some large enterprises to launch products earlier than their rivals, that is to seize the market earlier, then the investment is also cost-effective.

It can be seen that Dongguan new power plastic hand model is a relatively advanced industrial production mode, integrating automation and various advanced technologies, representing the advanced level of hand model production. As long as designers and engineers make good use of this, product development can be greatly reduced.
What is hand proofing? 2021-05-04 23:02:10
You may not know what hand proofing is. Simply speaking, after the design of the drawing is completed, you need to make a sample through 3D printing or CNC processing to test the appearance and functional structure, whether the assembly is consistent, whether the function meets the standard, whether the parameters meet the requirements, etc., so as to avoid the direct mold opening is difficult to modify and save the cost.

Because product development or design needs to be done by hand, making hand model is the first step to verify the feasibility of the product. It is a very direct and effective way to detect the shortcomings, drawbacks and defects of the product, so as to improve the defects. At present, hand proofing on the market is roughly divided into three categories: 3D printing hand, CNC hand, copying, reverse transcription and so on. However, 3D printing handboard and CNC handboard are very commonly used.

CNC hand processing strength and durability is very good, and the price is low, processing materials are ABS, plexiglass, PP material, PC material, copper, aluminum magnesium alloy, etc; In the fierce market economy competition mode of contemporary society, industrial design industry is gradually growing. Enterprises not only pay attention to industrial design, but also pay attention to the production of product model. The model can verify the quality of product development and the actual effect. In this case, professional model companies began to emerge.

3D printing technology is becoming more and more popular in China in recent years. According to the statistics of foresight Industry Research Institute, the scale of China's 3D printing market was about 1 billion yuan in 2012, which doubled to 2 billion yuan in 2013. However, compared with the United States, Germany and other developed countries, China's 3D printing industry is still in its infancy, and the domestic 3D printing application is still mainly in the scientific research stage, which has not been promoted in the industrial and personal consumption fields on a large scale.

According to the prediction of China 3D printing technology industry alliance, China's 3D printing output value is expected to reach 4 billion yuan to 5 billion yuan in 2014, and will expand to 10 billion yuan by 2016, 10 times of 2012 (1 billion yuan), so that China will surpass the United States and become a very large 3D printing market in the world. By 2016, the market scale can reach 10 billion yuan. The 3D printing market in China is very good. The government has also issued policies to support the development of this industry. It is difficult to completely replace a promising industry, but it has brought revolutionary reform to the mold industry.
