What Is The Impact Of Prototype Model Making On Product Design?

In the process of product design, when we complete the design drawings, what we most want to do is to know what we are designing, whether the appearance conforms to our design concept, and whether the structural design is reasonable. To meet this need, we manufacture handrail panels. Generally speaking, a prototype is one or more functional templates made according to the product appearance or structure drawing, and the rationality of the appearance or structure is checked without opening the mold.

Hand template making occupies a very important position in the entire industrial design system. It provides a reliable basis for enterprises to conduct appearance and structural design inspections, reduce product development risks, and quickly bring products to the market.

[1] The main production methods of hand model are CNC machining, laser rapid prototyping and small batch production of silicone replicas. When small batch production is required, silicone molds or fast molds can be used to achieve small batch production.

【2】Prototype model making function
1. Design inspection
The prototype is not only visible, but also touchable. It can directly reflect the creativity of the designer in the form of physical objects, avoiding the drawback of "beautiful drawing, not doing well". Therefore, in the process of new product development and product form evaluation, prototype production is essential.

2. Check Structural Design
Since the prototype can be assembled, it can intuitively reflect the rationality of the structure and the difficulty of installation. It is convenient to detect and fix problems early.

3.Avoid the risk of direct mold opening
Due to the high cost of mold manufacturing, larger molds are worth hundreds of thousands or even millions. If problems such as unreasonable structure are found during the mold opening process, the loss can be imagined. However, manual board manufacturing can avoid this loss and reduce the risk of mold opening.

Four. Get products to market early
Due to the advanced nature of hand-made, hand-made products can be used for publicity before mold development, and even in the pre-sales and production preparation work, so as to occupy the market as soon as possible.

【3】 What impact does handmade model have on product design?
Since model making is different from the processing and forming of open molds, there are still many shortcomings that will have a certain impact on product design. After the model arrives, some checks need to be done, one is a processing check and the other is a design check.one. Processing inspection.

A. Whether the appearance model is consistent with the design, whether the surface treatment process is consistent with the design, and whether the overall effect achieves the expected effect.

B. Check whether the structural model can be assembled, whether there is interference, whether there is design interference or model processing interference, and whether the model is consistent with 3D.
C. Are the model parameters within a reasonably controllable range for the design? The manufacturing tolerance of the handrail is generally between 0.5-1.5. The bigger the product, the bigger the tolerance, the bigger the variation of the sheet metal part. Therefore, it is necessary to make special marks on the model manufacturing instructions. These are the key dimension parts that need to be in place, which are matching dimensions and which need to be controlled, which should be clearly marked.

D. If the number of parts is missing, do not install the machine at that time. If there's a shortage of parts, there's trouble.

2. design check
A. After the appearance model is obtained, a design judgment should be made to check whether the appearance is beautiful, whether the proportion of the disassembled parts is coordinated, and whether the surface treatment is reasonable.

B. After the structural model is in hand, it is necessary to judge whether there are structural design defects after assembly, whether it is caused by model processing or structural design. For example: buckle, the designed buckle is 0.4, and it is very loose after the actual assembly, so it is necessary to determine whether the model is not processed properly, resulting in a reduction in the amount of buckle, so it is very loose, or the strength of the buckle arm is too long and weak, and needs to be tested.

C. Sheet metal parts need to detect the thickness, deformation and strength of the material. Assembly problems caused by processing deformation of sheet metal parts are assembly problems caused by processing deformation not considered in the design, or product deformation caused by model factory processing, which also need to be detected and considered.
