Investment casting (also known as lost wax casting) is an advanced manufacturing process used to manufacture precision metal parts from a wide range of standard and superalloy materials. The final product is not only accurate in size, but also durable, powerful, and adheres to some of the highest quality standards currently available. This is particularly true in the aerospace and medical industries, where investment casting is widely used as an economical way to produce complex geometric parts from difficult-to-process materials.

The investment casting manufacturing process is made by the first construction of wax moulds, which contain consumable parts in the pattern. The pattern of each part matches the geometry of the finished part, and the addition of a"Gate" creates an entrance for the metal to flow into the cavity later in the process. And then apply ceramic and plaster to the mold, until the shell thickness is approximately 3/8".". The wax is then melted from the ceramic cavity and filled with molten metal. The casting process is accomplished by removing the ceramic from the mold, cutting the existing metal parts free, grinding out the gate, and applying a final sand blast (see investment casting label, full overview) .

The key to producing investment castings with good dimensional precision is to start with high quality pattern and select correct scale coefficient. This is accomplished by manufacturing injection tools or printing part patterns directly from 3DCAD data and selecting a proportion factor based on the PAP alloy. At the HZMIM foundry, we are experts in all these areas, and our experienced foundry engineers can help you make the right decisions about what will be best for your application.

At HZMIM, we learned that high quality, low cost, and reduced production time are very important to our customers. To ensure that we are able to provide these elements, we employ lean manufacturing methods in every operation of our investment casting process. This will eliminate waste, reduce costs and improve quality. We integrated multiple steps into a single manufacturing process and cross-trained technicians. For example, wax injection, mold making, and first impregnation are all done by the same operator, which speeds up the process and minimizes hand shedding. The company uses the same manufacturing methods in all areas of its business, saving customers time and money.

We have a team of experts with extensive experience in manufacturing investment casting parts that meet the highest and most stringent industry standards. In addition, we focus on speed and are known for producing parts in the shortest production time. We also focus on customer service and communication to ensure that you will receive unparalleled service. So, if you are looking for a high quality investment foundry manufacturer, then do not look again, because we have covered you. Please contact us today for your next investment casting project.
