What is investment casting?

Investment Casting
Investment casting, or lost-wax casting, is an age-old manufacturing technique where molten metal is poured into a ceramic mold to produce precision parts. The process starts with creating a disposable wax pattern matching the desired part’s shape, which is then coated in ceramic slurry to form a mold. Once the mold hardens, the wax is melted out, leaving a hollow cavity for metal pouring.
 
Despite being a one-to-one process (one pattern per part), it enables the production of components with complex geometries and fine details. While it may involve longer production cycles and higher costs compared to other casting methods, investment casting stands out for its exceptional flexibility and precision, making it ideal for intricate part manufacturing.

Investment Casting Processes

Creating A investment casting Mold

Mold design ⇒

Unless investment casting is being used to produce a very small volume (as is common for artistic work or original jewelry), a mold or die from which to manufacture the wax patterns is needed.

2 Wax pattern creation

Wax pattern creation  ⇒

For every individual casting produced through investment casting, a new wax pattern is required, making the number of wax patterns needed equal to the total number of castings. Wax injection machine will do the job.

3 assemble wax pattern tree s 150x150 1

Assemble Wax Patterns Tree ⇒

Assemble the wax patterns to a gate or system. Multiple patterns are assembled to allow for large quantities to be produced at one time. This process will need workers do by hand and be very careful.

4 creating shell s 150x150 1

Shell building ⇓

creating a ceramic shell around the wax pattern to create a mold for the molten metal. The wax pattern is coated with a ceramic slurry, and repeated several times to create a thick, durable shell

5 wax removal s 150x150 1

Wax Removal  ⇒

Once the shell has hardened, turned upside down, placed in an special vacuum oven. They are heated to melt and remove the wax, leaving behind a cavity in the shape. The wax removed from the mold can be recycled after proper treatment.

Melt And investment casting

Casting and cooling  ⇒

The ceramic mold is preheated to around 1000 – 2000°F (550 – 1100°C) and filled with molten metal, liquid metal flows into the pouring cup, through the central gating system, and into each mold cavity on the tree. Then wait for cooling and solidify

7 casting removal s 150x150 1

Casting Shell Removal  ⇒

Once the casting solidifies, break the ceramic shell first with a Oscillating machine and then by hand, and use angle grinder to cut the individual investment castings from the sprue. Finally remove the excess metal from casting body by grinding.

investment casting Finishing and Subsequent processing

  • Key Factors Affecting Surface Roughness in Investment Casting‌

    When producing ‌precision investment castings‌, surface finish quality is critical for meeting tight tolerances and functional requirements. Several process variables can lead to ‌rough casting surfaces‌—here are the most common causes and proven ‌investment casting surface improvement‌ methods:

    ‌1. Low Viscosity in Surface Slurry‌

    ‌Problem:‌ Insufficient slurry viscosity creates poor coating adhesion, resulting in ‌rough investment castings‌.
    ‌Solution:‌ Increase viscosity by adjusting the binder-to-refractory ratio and maintaining optimal slurry temperature (30-45 sec Ford Cup #4).

    ‌2. Delayed Sand Stuccoing Process‌

    ‌Problem:‌ Prolonged wait times before stuccoing allow slurry to partially gel, degrading ‌investment casting surface finish‌.
    ‌Solution:‌

    • Train operators to apply stucco within ‌30-60 seconds‌ after dipping
    • Implement process audits to ensure timely sand application

    ‌3. Coarse Surface Sand Grit‌

    ‌Problem:‌ Large sand particles (>80-mesh) create texture transfer to castings.
    ‌Optimization:‌

    • Use ‌100-120 mesh sand‌ for surface layers
    • Balance fineness: Too coarse → Roughness; Too fine → Permeability issues

    ‌4. Excessive Sand Drop Height‌

    ‌Problem:‌ High stuccoing distance embeds sand into slurry, worsening ‌casting surface roughness‌.
    ‌Fix:‌ Reduce drop height to ‌<30 cm‌ and use fluidized bed sanders for even distribution.

    ‌5. Air Bubbles in Slurry‌

    ‌Problem:‌ Entrapped air causes pinholes in shells, leading to ‌defective investment castings‌.
    ‌Correction:‌

    • Add defoamers (‌0.1-0.3% by weight‌)
    • Use vacuum degassing or low-shear mixing

    ‌6. Incomplete Refractory Wetting‌

    ‌Problem:‌ Poor slurry homogeneity creates inconsistent ‌investment casting surfaces‌.
    ‌Best Practice:‌

    • High-shear mix for ‌20+ minutes‌
    • Age slurry ‌24-48 hours‌ for full hydration

    ‌Why Surface Finish Matters in Investment Casting‌

    Achieving smooth ‌investment casting surfaces‌ is essential for:
    ✓ ‌Dimensional accuracy‌ in precision components
    ✓ ‌Reduced post-machining costs‌
    ✓ ‌Improved fatigue resistance‌ in critical applications

    For industries like ‌aerospace investment casting‌ and ‌medical device investment casting‌, these optimizations ensure compliance with ‌ISO 9001/AS9100‌ standards.
