In relevant technical fields, the prototype is also called "sample", "sample making", "first model sample", "simulation sample", "imitation sample", "reference sample", "enlarged or reduced sample", "substitute material sample", etc. Let's talk about the classification, functions and relevant contents of the prototype.
Prototype models are generally divided into:
1. Outline plan; 2. Structure function manual; 3. Vacuum injection.
Handboards are divided into:
1. CNC prototype: It is mainly a prototype produced by the machining center. Its advantages are that it can accurately reflect the information expressed in the drawings, and the surface quality of CNC prototype is high, especially after the completion of surface spraying and silk screen printing. It is even more brilliant than the products produced after the mold is opened. Therefore, CNC prototype manufacturing has increasingly become the mainstream of the prototype manufacturing industry.
2: RP prototype: mainly produced by laser rapid prototyping technology. Its advantages mainly lie in its rapidity, but it is mainly formed by stacking technology. Therefore, RP hand boards are generally relatively rough, and there are certain requirements for the wall thickness of products. For example, if the wall thickness is too thin, it can not be produced, and it is easy to deform due to moisture.
Materials used for the production of the hand board: RTV-2 room temperature vulcanized silicone rubber, ABS, PMMA (acrylic), PC, PP, PA (nylon), PVC, PVC soft rubber, POM, copper, aluminum, steel, and bakelite.
Function of making hand board
1. Inspect the appearance design; 2. Inspect the structural design; 3. Participate in exhibitions to find customers; 4. Avoid the risk of directly opening the mold. 5. Conduct small batch production (1~100 pieces).
Manufacturing method of prototype product model:
1. Dewaxing method:
First, make a product model with paraffin, and stick a paraffin stick on the model (the future pouring mouth, referred to as the pouring mouth stick). Then hold the "pouring mouth stick" and pour the prepared "gypsum slurry" in the paper box. After 20 minutes, remove the paper box and put it into a 100 degree boiling water pot to "boil" for 30 minutes, allowing the wax to boil out completely. After being fished out, it is dried or dried in the sun. In this way, a mold is "successfully manufactured". Then, fill the heated and melted plastic from the pouring port, cool and open the mold. In this way, a product model with large finish is completed.
2. Copy method:
First, evenly apply a thick layer of "washing and cleaning" on your hands, and apply the cured "silicone mold glue" to your hands. Apply it every ten minutes for three times in total. In two hours, you can take off a "thick hand mold", which has a temperature resistance of 300 ℃. After the plastic is poured and solidified, the mold can be removed. A "prototype" product model is successful!
The manual post treatment processes include: oil spraying paint, electroplating, laser laser, silk screen printing, aluminum alloy anodizing., In this regard, we should pay more attention. For more information, please visit our website http://www.jrjmockup.com Consult!
