xiehe model

Rapid prototype making process, do you know what it is? Next, the Xiehe prototype processing factory will briefly introduce the production process of the prototype model.

Ninth, rough assembly

Due to the inherent defects of CNC machining, the clearing angle of the structure cannot be completely in place. Almost all the workpieces produced by engraving and milling need to be chiseled by hand with specific tools, and then the assembly relationship is adjusted. In this link, we must respect the engineer's design drawings, otherwise it is difficult to check the problems in the design for cooperation, and it is easy to cause the phenomenon that the prototype assembly is very good, but the injection molded product cannot be assembled. As a rigorous craftsman, if you find that there is interference in the design itself, you must mark it clearly and give it back to the designer for improvement;

Tenth, grinding and polishing

There will be knife marks on the surface of CNC processed products, and the appearance of each prototype model needs to be polished by hand. Moreover, this process is very intuitive to reflect the quality of a prototype.

1. Select sandpaper and polishing wax with different characteristics according to product type and material;

2. Carefully check the 3D drawings, analyze the key points of the appearance of the product, and reflect the edges, corners, lines, gaps, etc. of each part as accurately as possible;

3. The parts to be electroplated on the surface must be manually polished to reflect the effect of the mirror surface after electroplating;

Eleventh, oil injection/electroplating/anode

The biggest advantage of CNC prototype is that its surface effect is closer to the final mass production effect, which cannot be achieved by SLA. Even 3D printing technology is inferior to CNC prototype model in terms of surface treatment.

1. According to the process instructions provided by the customer, mix colors according to the color palette or PANTONE;

2. The sprayed product is baked in the oven, and the baking time will vary according to the characteristics of the material and paint;

3. After drying the paint, spray UV on the surface. UV can not only play the role of protection and reinforcement, but also beautify the paint effect.

Twelfth, silk screen/laser engraving

1. According to the vector diagram provided by the customer, make film and screen version;

2. According to the process description provided by the customer, silk screen printing or laser engraving;

3. Put the printed product into the oven to bake, and then cover the surface with UV. Some people like to print on the bottom of the UV, and some people like to print on the surface of the UV. Each has its own advantages and disadvantages and will not be analyzed here, and will be explained in detail later;

Thirteenth, finished product assembly

Both the exterior prototype and the structural prototype must be assembled.

1. Check whether the accessories of the products to be assembled are complete.

2. Assemble carefully according to the 3D drawings and process instructions provided by the customer. Special attention should be paid to the assembly relationship of the product and the gap between the parts;

Fourteenth, final inspection

All prototypes must be inspected for quality before shipment. Of course, it does not mean that quality inspection is only in the last link. The quality of prototypes is mainly controlled in each process. Once scrapped, it can only be redone. This will seriously delay the delivery of the product, so do The prototype should try to be 100% qualified and zero scrapped. Ensure on-time delivery while delivering prototypes that satisfy customers.

Fifteenth, packaging

Due to the different specifications of the prototypes, it is difficult to achieve "close-fitting" packaging for each prototype. It can only be packaged in the form of public boards, but each product must be shipped under the principle of ensuring confidentiality and safety.
