What details should be paid attention to when prototyping?

There are many details to consider when prototyping, as they affect the final product's appearance and can prevent cost waste during mass production. So, what details should be considered when prototyping? Here are some suggestions from our experienced technicians at Wangdefu Company:

In the early stages of prototyping, ensure the 3D model of the prototype is complete, without any missing features, and that key dimensions and surface requirements are clearly marked. Problems with the drawings will prevent further progress.

During the prototyping process, pay attention to the amount of glue used when bonding ABS prototypes. Insufficient glue will result in a weak product, while excessive glue will lead to higher labor costs during later sanding. Carefully review the product process drawings and 3D drawings, ensuring the dimensional accuracy of the prototype, including C-corners, R-corners, and product lines. During sanding, avoid sanding R-corners into right angles, and pay attention to any curved edges. When bonding acrylic prototypes, there should be no obvious glue marks or air bubbles. POM, nylon, and aluminum alloys have poor adhesive strength, so CNC machining should be avoided as much as possible. During assembly, avoid bonding in the wrong places, misalignments, and gaps to prevent rework. For painting, pay attention to color differences and fading; minimize dust adhering to the product during paint mixing and spraying. During molding, pay attention to deformation and shrinkage, and avoid excessive air bubbles and dimensional issues. For anodized products, ensure the outer surface is free of dirt, scratches, and color variations from the same batch.

The final acceptance of prototype samples must be strictly carried out according to acceptance standards. Carefully check the appearance, inspect key dimensions, and conduct functional tests.
