Following our deep dive into the earlier stages of production, we’re excited to share the next critical steps in our lost wax casting process for crafting durable, high-performance heat treatment fixtures.

Step 7: Finishing & Separation
Once cooled, the ceramic shell is carefully removed from the casting, revealing the raw metal structure beneath. Using precision cutting tools, we separate the final products from the pouring and feeding system—ensuring minimal material waste and preserving part integrity.

Step 8: Grinding & Shot Blasting
The sprue and gate remnants are meticulously ground off, followed by processing in our advanced automated shot blasting machines. Post-blasting, our quality team conducts a rigorous visual inspection against standardized checklists to identify and address any surface imperfections. This is how FH guarantees flawless castings, every time.

Step 9: Distortion Correction

Due to the intense forces during shot blasting, minor distortions in baskets or trays can occur.

Our technicians use precision press machines to realign components,

ensuring they meet strict dimensional tolerances before moving to final quality approval.

Step 10: Inspection

Every batch undergoes dimensional inspection and material composition testing,

and we issue inspection reports for every order.

Step 11: Packaging

Customized cases are made according to the size of the parts to ensure safe transportation.

Step 12: Shipping and Delivery

We collaborate with Global Logistics to provide door-to-door delivery, including customs clearance and compliance documentation.
