  Investment casting is also referred to as lost-wax casting and is a method used in the creation of parts that are complex and accurate in terms of precision. Quality of Investment castings is essential for the success of the final product particularly in aerospace, automobile, and medical device sectors.  Read this article to learn how you can identify high-quality investment castings. 1. Surface Finish This is one of the first things that can be used in identifying a quality investment casting and it involves the surface finish. By using this method of casting, the parts that are produced are often smooth and require minimal further finishing. An ideal cast will therefore have low surface roughness, pitting, or flash lines all of which are surface defects. It is also advisable to look at the surface under good lighting so that one can see any unevenness that may be seen as a sign of poor quality. 2. Dimensional Accuracy Another factor is dimensional accuracy. They also offe...

  What is Investment Casting? Investment casting, also known as precision casting or lost-wax casting, is a manufacturing process used to create intricate and highly detailed metal parts and components. This technique has been employed for centuries to produce complex shapes that are challenging or even impossible to achieve through other manufacturing methods. Investment casting offers exceptional precision and a high degree of customization, making it a favoured choice in various industries, including aerospace, automotive, jewellery, and more. Why is it Called Investment Casting? The term "investment" in investment casting refers to the process of investing, or covering, a wax pattern with a ceramic shell to create a mold for the molten metal. The wax pattern is 'invested' in the ceramic shell, hence the name. The term "lost-wax casting" also aptly describes this method since the wax pattern is melted and "lost" during the casting process, leav...

Investment casting, also known as lost wax casting, is a highly versatile and precise manufacturing process used to create complex metal parts. It has been employed for centuries and continues to be an integral part of modern manufacturing. In this article, we will delve into the intricacies of investment casting , its process, advantages, and important considerations for its successful implementation. Investment Casting (Lost Wax Casting): Investment casting is a metal casting process that involves the creation of a wax pattern, which is coated with a ceramic material. Once the ceramic material hardens, the wax is melted and drained, leaving behind a hollow cavity in the shape of the desired part. Molten metal is then poured into this cavity, filling it and creating the final product. The term "lost wax casting" comes from the fact that the wax pattern is lost or melted away during the process. The Investment Casting Process: a. Pattern Creation: The investment casting proc...
