What are automobile rp parts

by admin

RP is the abbreviation of Rapid Prototyping, namely rapid prototyping. RP prototype can be used for visualization of CAD digital model, design evaluation, interference inspection, and even some functional tests. In addition, the trial parts can enable users to intuitively understand the appearance and performance of products that have not been put into mass production and make timely evaluation, so that the manufacturer can timely improve the products according to user needs and market research, create favorable conditions for product sales and avoid possible losses due to blind production. Using RP parts trial production can optimize product design, shorten product development cycle, reduce development costs, and thus improve the competitiveness of enterprises.

Rapid prototyping parts are applicable to the trial production of prototype vehicles before the parts are molded, and the mold opening cost is very high

RP???? Character???

Automobile rp parts – automobile prototype is a new type of manufacturing technology developed in the 1980s, called Rapid Prototyping&Manufacturing (RP&M). At present, the rapid prototyping field can cover the following manufacturing technologies: 1. Laser rapid prototyping; 2. CNC machining forming; 3. Silicone mold production and vacuum injection small batch production; 4. Low pressure reaction injection (RIM) molding and small batch production of plastic parts; The automobile industry is China’s pillar industry, and China is becoming an important base for global automobile manufacturing. After China’s entry into the WTO, the pressure of domestic automobile manufacturing is increasing, and the research and development of automobiles is becoming more and more important. Trial production is an important part of automobile research and development. RP& As an important means, M technology is increasingly applied to automobile development. RP prototype can be used for visualization of CAD digital model, design evaluation, interference inspection, and even some functional tests. In addition, the trial parts can enable users to intuitively understand the appearance and performance of products that have not been put into mass production and make timely evaluation, so that the manufacturer can timely improve the products according to user needs and market research, create favorable conditions for product sales and avoid possible losses due to blind production. Practice proves that RP& M can optimize product design, shorten product development cycle, reduce development costs, and thus improve the competitiveness of enterprises. In addition to CNC rapid prototyping, the rapid prototyping parts of automobile hand boards also have low pressure reaction injection (RIM) molding. It is also known as Low Pressure Reaction Injection Moulding (RIM). It is a new process applied to the production of rapid tooling products. It mixes two-component polyurethane materials, injects them into rapid tooling at room temperature and low pressure, and forms products through chemical and physical processes such as polymerization, cross-linking and curing of materials. The utility model has the advantages of high efficiency, short production cycle, simple process and low cost. It is applicable to small batch trial production in the process of product development, as well as the production of small batch panels with simple structure and large thick wall and uneven wall thickness products. Technical parameters: applicable mold: ABS mold (more than 100 pieces); Resin mold (more than 300 pieces); Aluminum alloy die (more than 1000 pieces). Casting material: two-component polyurethane PU. Materials currently used: HD-PU4210, DCP-RIM, AXSON-RIM 875. Physical property: similar to PP/ABS. The product has the characteristics of aging resistance, strong impact resistance, high coincidence and easy loading and unloading. Injection pressure: about 10MPa. Flow control: 600g/s General working time: 15-30 minutes/piece. The demoulding temperature can be controlled below 40 ℃. After demoulding, the parts can be cured at 80 ℃ for 2-4 hours with the best performance. Standard reproduction precision: ± 0.20mm/100mm. Thickness of pouring sample: the optimal pouring thickness is 4~6mm, and the maximum pouring thickness is 10mm. Maximum pouring workpiece: 2000mmX1200mmX1000mm, 10KG.
