Our Process - Helix Technocast

Trusted Aerospace Manufacturing Solutions

Delivering precision-crafted aerospace components with uncompromising quality, lightweight performance, and superior reliability. Built to meet global aerospace standards and customer specifications.

Investment Casting Process

The investment casting process begins with the creation of precise wax patterns that replicate the final component design. These patterns are coated with ceramic layers to form a durable mold. Once the wax is removed, molten metal is poured into the cavity, producing highly accurate and complex aerospace components with excellent surface quality.

Machining Process

After casting, components undergo precision CNC machining to achieve exact dimensions, tight tolerances, and superior surface accuracy. Advanced machining centers ensure every aerospace part meets strict engineering specifications and quality standards.

Finishing & Coating

The finishing and coating stage enhances component durability, corrosion resistance, and appearance. Depending on application requirements, parts may undergo polishing, bead blasting, anodizing, powder coating, or specialized aerospace surface treatments.

Packaging & Dispatch

Every component is carefully inspected, packaged, and labeled to ensure safe transportation and delivery. Protective packaging materials and strict quality checks guarantee products reach customers in perfect condition and ready for installation.

01. Wax Pattern Injection

High-precision wax is injected into a metal die to create an accurate replica of the final component, ensuring dimensional consistency and repeatability.

02. Pattern Assembly

Individual wax patterns are assembled onto a central runner system to form a complete casting tree, optimizing production efficiency.

03. Shell Building (Dipping)

The wax assembly is repeatedly dipped into a premium ceramic slurry to create the first layer of the ceramic shell with exceptional surface finish.

04. Shell Building (Stuccoing)

Fine refractory sand is applied over each ceramic layer to strengthen the shell, creating a durable mold capable of withstanding molten metal.

05. Drying

Each ceramic coating is carefully dried under controlled conditions to ensure maximum shell strength and eliminate moisture before casting.

06. Wax Removal (Dewaxing)

The ceramic shell is heated in an autoclave or furnace to completely remove the wax, leaving a precise hollow cavity for metal pouring.

07. Shell Removal

After solidification and cooling, the ceramic shell is broken away through vibration or blasting, revealing the finished metal casting.

08. Cut-Off & Finishing

Individual castings are separated from the runner system and undergo grinding, machining, polishing, and quality inspection to achieve the required specifications.
