Tooling Technology

This paper discussed the working principle, classification, modeling process and technology features for rapid tooling based on rapid prototyping and investigated into the difference between rapid tooling with traditional modeling manufacture. Several typical rapid tooling technologies are compared and summarized from mould period, fabrication cost and production cycle. Some key problems that rapid tooling industry will face with are analyzed. The application of the rapid tooling based on rapid prototyping is prospected.

The results of computer simulation of thermoforming process made using ANSYS Polyflow software are presented in this paper. The analysis of the wall thickness distribution across an U-shaped thermoformed product manufactured using a positive mould was made. The simulation results were verified using a mould manufactured in a 3D printing process which was Fused Deposition Modelling (FDM) and a poly(ethylene terephthalate) formed sheet. It was proven that the computer simulation and a tool made with a Rapid Tooling technology can be useful for predicting the quality of a thermoformed part, particularly to find the problems with thin-walled areas.

Although pressure compensating emitters (PCE) have many advantages, they are difficult to develop and very costly. Traditional PCE are composed of emitter structures and compensating diaphragms. Their manufacture is very difficult and time-consuming. In this paper, we invented novel PCE with variable flow channels, which are designed as integrated structures with pressure compensating barriers, and manufactured three of them with different structures based on the rapid prototyping/rapid tooling technology. The pressure-flow test showed their behavior indexes were 0.009, 0.008 and 0.011, respectively, indicating this type of novel PCE have remarkable compensating effect.

Diffractive optical element (DOE) is widely employed to convert light wave fronts in many different applications. This study demonstrated a precision hybrid rapid tooling for manufacturing the DOE. The transcription rate in the rapid tooling manufacturing process is about 92.5%. The transcription rate in the molded part is about 95.1%. Hybrid rapid tooling technology not only reduces the fabrication cost of rapid tooling but also has higher form accuracy and higher thermal conductivity. In comparison with conventional method for fabricating a pair of rapid tooling of a new DOE, a cost reduction of 60.4% can be achieved using a hybrid rapid tooling technology.

Rapid tooling technology is regarded as an important method of reducing the cost and time to market in a new product development process. Epoxy-based composites mold is frequently employed in the intermediate tooling. Based on green manufacturing, an environment friendly process for making epoxy-based composites mold is developed and implemented in this work. This method provided a new, simple, and green manufacturing to produce green rapid tooling without loss of dimension accuracy and surface roughness. The advantages of this method include high yields of the mold fabrication, reducing the cost in the mold fabrication, and environmentally conscious manufacturing. The saving in the cost of the rapid tooling is up to 52.5%.
