Quality Management

Our manufacturing process and raw materials comply strictly with the industry regulatory standards, including the ISO 9001, and Quality Management System.

Investment Casting Process

Create the Pattern

The success of investment casting is dependent on several factors, including the type of alloy and the size of the casted part. As a leader in investment casting, our unparalleled knowledge and experience with cutting edge technology are combined to determine the best solution for your project.

Wax Injection & Assembly

The first step is to develop the pattern. This is done by injecting wax into a die or metal tool to solidify into a single piece. Through the use of our additive manufacturing technology to 3D print patterns, fast samples are made.

Shell Making

Once the pattern is created, they are connected to a central wax gating system, which comprises the sprue, to make the tree assembly. Instead of making the parts one at a time, the sprue functions as a mounting surface to cast several patterns into one mold, which is later injected with an alloy.

Melting and Pouring

After the wax pattern tree is assembled, it’s inserted into a ceramic slurry and covered with coarse material. When the slurry is dried, it results in a ceramic shell around the wax tree. This step is done repeatedly until the mold shell is very thick and hardened completely.

Complete the Process

Once the part is cooled, it’s removed from the sprue. The part surface needs to be finished by grinding, smoothening, polishing, and machining it to have the appropriate curve and geometry.

Laboratory Inspection and Testing

Before delivery, the castings are inspected thoroughly to identify defects and make immediate modifications. This is done to ensure consistent product quality, hence eliminating the risk of failure during usage.

Investment Casting Quality Control

Investment Casting Service By Materials

Stainless Steel Investment Casting

Having high resistance to wear and corrosion, stainless steel is commonly used for demanding applications without the need to apply secondary coating or plating. Industries that usually use this material are oil & gas, defense, medical, etc.

Carbon Steel Investment Casting

It’s also known as plain steel as it contains mainly carbon, which contributes to its properties. It is very hard and strong, making it suitable for several heat applications. Some of its uses include ground-based military vehicles and roughneck equipment for oil & gas operations.

Available Investment Casting Finishes

Stainless Steel Shot Blast

Using abrasive media, this finishing technique uses a fast impact process on the surface of the castings. It removes post-casting and heat treatment scaling which result in a uniform, even visual finish. This technique is quicker and more effective than fettling for flash and gate removal on casted parts.

Powder Coating / Painting

This is an effective, environmentally friendly, and high quality finish, which involves forming of a skin over the casting. Powder coated and painted parts have great resistance to impact, chemicals, moisture, and other harsh weather conditions. They retain their beauty and smoothness as this process reduces the risk of abrasions, scratches, fading, chips, and other wear & tear problems.

Electropolishing

This finishing technique is commonly used to remove a thin layer from the metal part surface, thereby improving the surface quality by 50%. It’s 30 times better than mechanical polishing. Electropolishing is often used for equipment made with stainless steel and similar alloys which are applicable in the food and chemical processing industries.

Light Aluminium Oxide

Using aluminum oxide is a cost-effective way to get uniform finishes on products. It’s very similar to stainless steel shot blast, but uses a more abrasive sand-like media, leading to less shatter of the particles. This in turn, result in lower dust levels. Also, since it has a low content of iron, when used, it won’t leave any rust on the casting surface.
