Prototype is in the form of material object to reflect the designer’s creativity. It can test the appearance and structure, and according to the appearance drawing or structure drawing to make one or several samples on the premise of without opening the mold.
The superiority of acrylic（PMMA）by
CNC processing:
General machine tools cannot solve the problem of automatic processing for complex parts. NC machining has the characteristics of strong adaptability, high machining precision, high production efficiency and beneficial to the modern production management, after being applied to the prototype processing, the prototype can reflect the drawing information accurately, save money, enjoy high surface quality and improve the production efficiency circle.
Prototype has a variety of materials, SLA mainly use the material of photosensitive resin. Silicone rubber mould is mainly used in mold replication by vacuum casting. The material of CNC processing is divided into metal and non-metal, while non-metal mainly refers to a number of engineering materials, such as ABS, PC, PP, POM, PA, PMMA (acrylic), bakelite and wood etc.
Generally, the material of CNC processing is the plate, which has a standard thickness. Usually the thickness of the plate above 100mm is difficult to order, once the plate with 150mm will need customized, so the price of the plate is different in the prototype processing, and the special thickness has different price.
Yakeli(PMMA)translated from Acrylics, the acrylic board is composed of methyl methacrylate (MMA) that is polymethyl methacrylate(PMMA) organic glass. Acrylic has characteristics of high transparency(light transmission rate up to 92%), excellent weather resistance, good surface hardness and luster and great processing plasticity. Acrylic(PMMA) is usually used in the prototype with high transmittance, such as car lights, lens etc.
