Determine material properties
High temperature, strong wear resistance, high toughness required by product materials are different, but the whole treatment and related materials are also required. If you need a high temperature resistant hand board, you can work well with PPS and can withstand 300 ° C high temperature; If you need to make transparent hand boards, PC and acrylic materials are preferred.
Conventional product hand board: ABS material is generally selected, which is easy to process and beautiful after treatment.
High temperature resistant product hand board: materials such as epoxy resin, black PC and PA (nylon) can be selected. Except for black PC, the other three materials can not be bonded and need to be processed as a whole.
Wear resistant product hand board: POM or PA can be selected. The hand boards made of these two materials can not be bonded and need to be processed as a whole.
High toughness product hand board: PA or PP can be selected. The hand boards made of these two materials can not be bonded and need to be processed as a whole.
Transparent product hand board: PMMA (acrylic), transparent ABS, transparent PC and other materials can be selected. The hand board made of these materials is highly transparent through polishing and achieves the same effect as the real product.
Determine processing method
CNC is a widely used hand board manufacturing method in China. It is mainly used for plastic and metal plate processing. The materials are carved and milled on the CNC technology processing center, and then processed by hand with exquisite ability. The CNC processing hand board and model are completed.
3D printing is an additive manufacturing technology. The printed products are stacked on the plane and accumulated layer by layer. 3D printing includes SLA, SLS, SLM, FDM and other technologies, and SLA technology materials are mostly resins; The materials of SLS technology are wax powder and plastic powder; FDM is generally made of thermoplastic materials, such as wax, ABS, nylon, etc., which are supplied in filaments to cover most types of products on the market.
Vacuum replica is to use product prototype (such as SLA or hand plate processing) to make silica gel mold under vacuum, and pour it with PU material under vacuum, so as to clone the same replica as the product prototype.
Jinan prototype manufacturers remind that vacuum replica is a popular prototype replication technology, which is used to change the material of product prototypes, assemble prototypes or carry out small batch production of products, so as to meet the requirements of performance testing, market promotion, inspection and approval in the process of product development; Different PU materials can be used to copy rubber parts, transparent parts, high temperature resistant parts, etc; However, the vacuum compound PU material is brittle, with poor toughness and high temperature resistance.
