Silica Sol Precision Casting Process

STEP 01

Wax Pattern Creation

Wax patterns are produced according to the customer’s CAD drawings or samples. This step determines the final dimensions, shape, and surface quality.

STEP 02

Shell Building with Silica Sol Slurry

The wax pattern is repeatedly dipped in a high-purity silica sol slurry and coated with refractory zircon sand, forming a strong ceramic shell.

STEP 03

Drying

Each layer is dried in a constant temperature and humidity environment to avoid cracks and ensure shell integrity.

STEP 04

Dewaxing & Shell Sintering

Wax is removed, and the ceramic shell is sintered at high temperature to achieve strength and dimensional stability.

STEP 05

Metal Pouring

Molten stainless steel 304, 316, carbon steel, alloy steel, or non-ferrous alloys are poured into the shell.

STEP 06

Shell Removal & Cleaning

The shell is broken away, and the raw casting is cleaned of any residual material.

STEP 07

Heat Treatment & Finishing

Heat treatments such as annealing, hardening, tempering, or surface hardening are applied to improve mechanical properties. Surface treatments like electropolishing or mirror polishing are available upon request.

Advantages of Silica Sol Investment Casting

· High Dimensional Accuracy – Tolerance grade CT4–CT6, ISO 8062 standards.
· Excellent Surface Finish – Ra 1.6–3.2 μm as-cast, Ra 0.8–3.2 μm after machining.
· Complex Shape Capability – Thin walls (0.5–0.8 mm) and intricate geometries.
· Material Versatility – Stainless steel, carbon steel, alloy steel, aluminum alloys, copper alloys.
· Reduced Machining – Near-net-shape production reduces post-processing time and cost.
· OEM & ODM Service – Fully customized according to drawings or samples.
