Rapid prototyping (RP) is fast becoming a standard tool in today’s product design and manufacturing environment. Significant
benefits in terms of lead time and cost savings have been reported with the use of RP technology. However, these benefits
can be derived only during the design and planning stages of a new product where RP parts are produced in small quantities
for design evaluation, form fitting, and marketing analysis. The high cost of raw material stock used in current RP systems
makes them economically unsuitable even for small-batch production during the product evaluation and manufacturing stages.
Further to this, the difference between the mechanical and physical properties of RP and traditional manufacturing materials
limits the functionality of RP end products. Rapid tooling (RT) technology has opened up new cost-effective solutions for
small-batch production. In this paper, a technique using a rapid soft-tooling approach, namely, aluminium filled epoxy resin
tooling for injection mould preparation is successfully explored. An aluminium filled epoxy resin mould is evaluated and the
characteristics of the injection-moulded end products are presented. 相似文献

In order to build the complex built-in labyrinth design of an emitter which is a key element in water-saving devices, rapid prototyping and manufacturing (RP&M) is used to design the emitters and to manufacture corresponding rapid tooling (RT). Detailed CAD design of the emitter, CAD process design, and the generation of RT process modelling of the emitter have been carried out using parameterised design. Prototypes have been built using RP techniques to perform the rapid verification and modification of the emitter design; rapid tooling (RT) for the emitter has been fabricated using a metal spraying process to carry out trial-production. Finally, with the fabrication ofa precision mould as the basis, emitter mould design and manufacturing have been completed. As a result, the integration of design/verification/manufacturing of a mould and its products is realised. 相似文献

Rapid tooling (RT) is the technology that adopts rapid prototyping (RP) techniques and applies them to tool and die making.
Research into RT techniques has shown that it is gaining more importance and is starting to pose a serious threat to conventional
machining. In this paper, several popular RT techniques are discussed and then classified. A comparison is also made on these
techniques based on tool life, tool development time and cost of tool development. 相似文献
