Utilizing PROE 3D design software for mechanical product assembly modeling, and then using its 2D capabilities to draw production and manufacturing drawings according to national drafting standards. Products designed and drawn for clients include motorcycle frame welding, multi-functional bending machine, roller mill (surveying), leg positioning fixture, high-temperature and high-pressure steam cookers (chemical machinery), small hotel beer production line design, and more. We can provide images or video materials of related works. Currently, we are designing a rice hull flattener for a chicken farm of COFCO Group. Below are some of my R&D designs, most of which have been patented and applied. I have extensive experience in mechanical R&D design, adhere to strict drafting standards, and have a short R&D design cycle. Give me a chance, and I'll give you a surprise.
