This paper try to analyze the rheological behavior during the wax injection, and build a mathematical model to simulate the wax injection process. By using Moldflow, simulate a wax pattern with different ingate configurations to optimize the injection modeling product design. This study helps to improve the model design quality, shorten the development cycles, lower down the overall cost and enhanced competition in market.

Wax Injection

The accuracy of the wax patterns used in the investment casting process has a direct bearing on the accuracy of the final cast part. Wax injection process plays a key role in production of nearly net shape wax pattern. Dimension shrinkage is one of the most significant problems of a wax pattern in terms of dimensional stability in the wax injection molding. This study aimed to determine the effects of injection parameters on the dimensional accuracy of the wax patterns. Linear contractions normal to flow direction and weight of wax patterns were measured and dimensional variations were evaluated. The results highlight it is important that when dealing with thick gates, short packing time appears to be the best way to avoid gate area over packing and dimensional variations, high packing pressure appears to increase expansion and dimensional variation of wax pattern.

Wax Injection

Investment casting is often used to produce fully functional prototype components from sacrificial patterns. These patterns (prototypes) may be made using specialized rapid prototyping techniques such as stereolithography or three-dimensional printing. When multiple functional prototypes are required, interim tools for making wax patterns are employed. The objective of this research work was to determine the precision and accuracy of wax patterns produced using several prototype tools. Linear contraction was used to determine the accuracy as a function of the wax injection parameters used in low-pressure injection moulding. Wax patterns were produced using polyurethane and silicone rubber tools. It has been shown that the accuracy of patterns from both tools is similar. However, silicone tools produce patterns with much higher contraction than those produced by polyurethane tools. Unconstrained patterns dimensions contracted as much as 3.44 ± 0.40 per cent and 1.70 ± 0.60 per cent for silicone and polyurethane tools respectively. The constrained dimensions contracted by 2.20 ± 0.20 per cent in the case of silicone tools and 1.40 ± 0.20 per cent in the case of polyurethane tools.
