How KEMING Provides You with Investment Casting Services

Tooling Creation

We start by making precise tooling using CNC machining. This tooling forms the pattern for casting. Customers pay a one-time tooling fee for new products, waived for future orders.

Wax Pattern Production

Wax is injected into the tooling to create wax patterns matching the product design. Multiple wax patterns are made and assembled on a sprue, then dried at room temperature.

Ceramic Shell Building

The wax assembly is carefully dipped multiple times into a specially prepared ceramic slurry, which gradually builds up a thick, strong shell around the wax pattern to prepare for casting.

Dewaxing and Shell Firing

The ceramic shell is heated in a steam autoclave to melt and remove wax. Then, the shell is fired at high temperatures to harden and prevent cracks or defects before the casting stage.

Metal Casting

Molten metal is poured into the preheated ceramic shell mold. After allowing it to cool naturally at room temperature, the metal solidifies completely, forming the precise desired shape.

Shell Removal

The ceramic shell is carefully broken apart to release the metal castings inside. Afterward, excess metal is removed by grinding to ensure the castings have the correct shape and finished surface.

Optional Heat Treatment

If requested, castings undergo heat treatments like annealing or hardening to significantly improve their mechanical properties and durability. Additional costs apply for these services.

Shot & Sand Blasting

Castings are thoroughly cleaned by shot blasting or sand blasting methods to effectively remove scale, rust, and other surface impurities, thereby significantly ensuring a smooth finish.

Surface Treatment

Castings are initially treated with anti-rust oil or water. Additional surface treatments such as painting, powder coating or galvanizing can be applied depending on specific requirements.

Quality Control

Engineers carefully perform detailed dimensional, surface, and internal inspections on all products. Only products meeting quality standards are approved for delivery to customers.

FAQs About Investment Castings

Investment casting is generally more expensive than other casting methods like sand casting or centrifugal casting. The high cost mainly comes from tooling and engineering, as investment casting requires complex wax patterns and single-use ceramic molds. Material costs also add up, especially when using premium alloys. Additionally, specialized equipment and labor-intensive steps contribute to the overall expense.
However, investment casting offers excellent precision, smooth surface finishes, and the ability to produce intricate and detailed parts, which can reduce post-casting machining costs. The price varies depending on part size, complexity, material, and quantity.
For reliable and cost-effective investment casting services, KEMING is a recommended manufacturer. KEMING specializes in high-quality investment casting with advanced technology, ensuring precise and durable metal parts. Their expertise helps optimize costs while maintaining excellent quality, making them a trusted choice for complex casting projects.

Investment casting is used when you need parts with high precision and smooth surfaces. It is ideal for making complex shapes that are hard to create with other methods. This process works well for small to medium-sized parts and can use many types of metals, including steel, aluminum.
You should choose investment casting when you want to reduce machining time because the parts come out close to the final shape. It is also good for producing parts with thin walls and fine details. This method is often used in industries like aerospace, automotive, and medical devices, where accuracy and quality are important.
In summary, use investment casting when you need detailed, accurate metal parts with a smooth finish, especially if the design is complex or requires tight tolerances.

Smooth Surface Finish: It uses ceramic molds, producing parts with very smooth surfaces, often around 125 RA, which reduces the need for extra machining.
High Precision and Tight Tolerances: Investment casting can achieve tight dimensional tolerances (about ±0.005 inch per inch), allowing for precise and complex shapes.
Complex and Intricate Shapes: It can create detailed parts with thin walls, undercuts, and internal passages that are difficult to make with other methods.
Wide Range of Sizes: It can produce very small parts weighing less than an ounce up to large parts weighing 50 pounds or more.
Material Versatility: Many metals can be cast, including stainless steel, bronze, aluminum, nickel-based superalloys, and cobalt alloys.
Lower Tooling Costs and Faster Production: Tooling is less expensive than other casting methods, and the process reduces machining time, leading to quicker production and cost savings.
Near-Net Shape Production: Parts come close to final dimensions, minimizing waste and machining.

When choosing the right investment casting supplier, focus on several key factors. First, consider the supplier’s experience, especially in your industry, to ensure they understand your specific needs and challenges. Quality and repeatability are crucial; the supplier should have strong technical capabilities, including advanced tooling and simulation software, to deliver consistent, high-quality parts. Certifications and testing capabilities matter if your application requires them. Also, assess the supplier’s ability to provide value-added services like design support and alloy selection advice. Price and customer service should align with your priorities, whether you need the lowest cost or the best service. Finally, check if the supplier can handle your required production volume and part complexity efficiently.
