The influence of the mold quality and injection pressure on the product quality

This study deals with the study of the influence of injection pressure parameters and the quality of the surface of the mold cavity on the final quality of the product surface. This issue represents a significant problem, especially in the area of the mold production and the determination of its product price. The final price is closely linked just to the surface quality. This study is concentrated on three basic qualities of machining, namely Ra 0.1, Ra 0.8 and Ra 1.6. The possibilities of the replication of the surface of the mold cavity are then combined with various values of injection pressure, which has also the inconsiderable influence on surface replication. Total results show the influence of injection pressure and its most suitable value for obtaining the best identities of both surfaces.

Application Research of Numerical Control Machining Technology in Mechanical Manufacturing

Mold manufacturing is an important part in mechanical manufacturing, and casting quality of mechanical manufacturing is influenced by mold quality directly. If mold manufacturing still adopts the traditional mode, that will has a severe dependence on core box or appearance, often with a relatively long period and relatively high cost, which will be hard to satisfy the rapid development and manufacturing of small batch sheet parts. This article introduces the application of new product development, processing equipment performance and process principle of metal parts no-mode numerical control processing and manufacturing technology, the technology in mechanical manufacturing process. This technology is to thoroughly change the traditional craft with no need of modes, and is able to cast accurate and quick production. Its main characteristics are flexible, digital, greening, motors, etc., which provide the corresponding solutions for rapid manufacture small batch sheet metal.

The Coding System for Automatic Injection Mold Integrated CAD/CAPP

Based on the Group Technology and according to the function, structure and manufacturing process of the injection mold, a classification and coding system for injection mold is developed specially. The system is mainly centre around the classification, code structure and the way of the coding, by which the information description and transmission between CAD and CAPP becomes unblocked, the mold CAD/CAPP integration and automation in design and process comes true. It is supposed to help reduce the time in process planning, increase plan consistency and efficiency, improve mold quality and minimize the time-to-market for the mold products.

The Collaborative Design and Manufacture of Injection Molds Based on the CSCW

Cooperative work environment supported by computer (CSCW) is a platform for sharing information, which supports the exchange of design ideas of different teams. The collaborative design and manufacture of injection molds based on the CSCW can shorten the life cycle of mold development, improve the mold quality and lower the development cost. This paper describes the framework of collaborative design and manufacture for injection molds, discusses the construction of the organizational model and analyzes the workflow of design and manufacture.

µ-Mold Shape Deposition Manufacturing of Ceramic Parts

Rapid Prototyping is a versatile method to build complex-shaped ceramic or metallic parts on a mesoscopic scale. In this work the fabrication of ceramic gas turbine engine parts with Mold Shape Deposition Manufacturing (Mold SDM) is described. Mold SDM exists of two steps: The pattern generation in wax using deposition and machining of wax layers and the pattern transfer process with gel-casting. For parts with feature sizes that are too small for machining, microfabrication methods are used to fabricate the mold. By combining micro- and macro-fabrication, complex parts in a wide variety of sizes can be manufactured.The surface quality of the mold significantly influences the mechanical properties of the final ceramic part. The contribution of the mold quality to the final mechanical properties is studied in this work.
