How to avoid waste of investment castings due to design problems?

With the continuous development of manufacturing technology, investment casting has become an indispensable part of many mechanical equipment, automobiles and electronic products. In many industries, investment casting parts are necessary. However, if there is a design problem, it will lead to unnecessary waste and increase the production cost. So how to avoid waste when designing investment castings? Here are some suggestions.

First of all, the processing method of precision castings should be fully considered in the design stage. The process, cost and feasibility of mold manufacturing should be considered in the design. Avoid designing parts with complex shapes and internal holes, or parts that are too small, which will increase the difficulty of manufacturing, increase the cost, and may lead to an increase in the rate of defective products.

Second, choose the right material. Designers should fully understand the properties of different materials and choose suitable materials to ensure that they can meet the requirements of the product. However, it should be noted that the cost of high-end materials is usually relatively high, so the cost should also be considered in the design to avoid excessive use of expensive materials.

Third, ensure precision. Precision castings usually require very high precision. Designers should take into account the changes of metal during melting and solidification, the expansion and contraction of materials, and minimize the errors caused by factors such as temperature and flow to ensure that the products meet the requirements.

Fourth, apply simulation software. During the design process, simulation software can be used to test the rationality of the design. Through simulation software, the processing difficulty and manufacturability of a job can be effectively evaluated. If manufacturing modifications are required, early detection will be more convenient and beneficial to the manufacturing process.

Fifth, work with suppliers. When designing investment castings, working with suppliers can reduce waste due to incorrect material or design choices, and can also find cost solutions before the design is completed. Collaborating with suppliers can also result in shorter product development cycles and better technical support.

In conclusion, the design stage is crucial to the quality, production efficiency and cost of investment casting parts. In the design stage, materials, processing, and cost solutions should be considered, and actively cooperate with suppliers to reduce waste caused by design errors and improve the cost-benefit ratio of products.
