The purpose of making hand board is to verify whether the product design is reasonable and whether it meets the use requirements of the product, and can detect the structure, appearance and function of the product. Before making the hand board, it is necessary to prepare the 3D drawing of the design of the prototype. The 3D drawing is generally in the format of IGS, STP, step, PRT and XTL. It is based on the design of the drawing to process the hand board. According to the template, there are several common Processing method:
3D printing: Laser Rapid Prototyping SLA / SLS is not limited by the shape. It can print any complex shape hand board. The more complex it is, the more it can show the advantages of 3D printing technology. No matter how complex the template is, it can be printed. Its advantage is to reduce the production cost and time cost. This kind of processing method is charged by weight. It is not cost-effective if 3D printing is used for large-scale handpieces.
CNC processing: the processed materials are very wide, except for soft rubber, other plastic and metal materials can be processed, and the processing precision is high, which can reach 0.02-0.10 mm; its characteristics are high speed, high strength, and can process large-scale hand board, and the shape of CNC processing will be limited. If the hand board is too complex, it needs to be disassembled.
Vacuum re mold: for small batch production, the original version should be made first, and then a silica gel mold should be made. The production cycle of silica gel mold is short, the price is cheap, and it is easy to occupy the market. It is suitable for small batch production. A silica gel mold can make about 10-15 pieces. If it is used again, it is easy to deform and shrink. Under vacuum condition, the castable can be defoaming, stirred and pre processed The hand model of silica gel compound mold can reach the strength and hardness of ABS and other materials.
