The design process is applied to the Pro/Engineer, AutoCAD and some other commonly used CAD technology, moreover also relates to the application of Photoshop. With the traditional mold design, in many aspects has great superiority. In a mold design is the difficulty of design process hole. Is the use of the plastic parts of the design to replace the side core pulling, replace sb. This design is for the purpose of understanding and consolidate the mould design process. Injection mould for plastic molding plastics is an important process equipment, based on the fixing device mold design, can fully understand the plastic mold design basic principle, method of. And more skilled use of Pro/Engineer, AutoCAD software for plastic mold design, to improve their drawing skills, to engage in design work and lay a solid foundation.
