The whole plastic engine USES 3D printing polyamide
In the new forward-looking automotive full-plastic engine project Polimotor 2, selective laser sintering (SLS) process (a 3d printing technology) is used to manufacture the intake manifold of the engine. But behind this cutting-edge technology, solvay offers Sinterline ® Technyl ® polyamide 6 (PA6) powder. The 40% glass beads in this material can effectively improve the dimensional stability of the parts. Polimotor - 2 this remarkable all plastic automotive engine project, by the legendary automotive engineers it Holtzberg chair design, to develop a new generation of all plastic automotive engine, and plans in 2016 the first installed in the car. Solvey is the main material technology supplier for the innovation project. Holtzberg, founder of the project evaluation way: "Polimotor - 2 for the first generation in the 1980 s Polimotor engine design concept, emphasize the groundbreaking polymer technology, the design of the vehicle routine, change vehicle performance and related manufacturing process." Holtzberg is also President of the Composite Castings, which is based in west palm beach, fla. He added: "Polimotor - 2 engine intake manifold was originally prepared to continue to use the first generation of the engine intake manifold injection molding manufacturing process, but later we found use Sinterline Technyl polyamide 6 materials produced by 3 d printing process intake manifold has more excellent reliability, can withstand the car using the environment in various harsh test." Based on the special resin-chemical technology of solvay Technyl polyamide series, sinter-line polyamide 6 powder materials are specially applied to the manufacture of polyamide plastic parts suitable for 3d printing process. Selective laser sintering, such as 3 d printing process does not need to make mold or prototype parts in advance, can quickly convert digital design into real parts, thus greatly shorten the design cycle and reduce the manufacturing cost, effectively improve the overall efficiency. Therefore, such technology can significantly accelerate the production of vehicles and parts manufacturing market speed. Laser sintering process by high precision laser scanners to exert energy, step by step to Sinterline Technyl polyamide 6 powder fusion, eventually forming features excellent 3 d parts, and with a strong mechanical properties and heat resistance. The laser sintering process can easily realize the complex components of internal structure and function. Solvay engineering plastics Sinterline project director Dominique Giannotta said: "as the first designed for selective laser sintering process of polyamide 6 powder, Sinterline series materials can realize various avant-garde design, at the same time made a performance with polyamide injection as comparable, it will no doubt 3 d printing technology is making a big push again. And the cutting-edge technology in the Polimotor - 2 engine application validation, this also is the solvay engineering plastic over the years adhere to the strong evidence of positive innovation, at the same time reflect the advanced material in aspects of commercial vehicles and the car design problems in huge potential." The automobile intake manifold is a pressurized structural component that realizes the uniform distribution of air flow between the inlet and the cylinder. The air intake manifold of the Polimotor-2 engine is similar to that of the traditional automobile intake manifold which is now industrialized and used for injection molding of polyamide materials. The wall thickness is 2-3mm and can withstand the positive pressure of 2-4 bar. Using Sinterline Technyl of polyamide 6 powder print parts in traditional metal turbo engine up to 250 ° F (121 ° C) thermal radiation temperature also showed a stable performance. To explain: since Polimotor - 2 engine main parts are made with low thermal conductivity of plastic, so its relatively low temperature around the intake manifold, general is 150-200 ° F (66-93 ° C). Highly innovative Polimotor - 2 project aims to develop a full plastic overhead double CAM four-cylinder engine, the weight is about 138-148 pounds (63-67 kg), a typical traditional automobile engine lost about 90 pounds (41 kg). Besides has successful application of the intake manifold, solvay advanced polymers technology will be applied to this pioneering project in dozens of other components, including water pump, oil pump, water inlet/outlet, throttle valve, high-performance fuel rail and other accessories. The other solvay polymer used in the project including Amodel ® poly phthalic acid (PPA), KetaSpire ® (PEEK), polyether ether copper AvaSpire ® aromatic ketone ether (PAEK), Radel ® polystyrene sulfone (PPSU), Ryton polyphenylene sulfide (PPS) (PPS) and Tecnoflon ® ® VPL containing fluorine elastomer.
