Lost-wax Casting: Foreign Matter Contamination Countermeasures | Prevent Foreign Matter Contamination through Integrated Control

Measures Against Foreign Matter Contamination in Lost-Wax Casting | Preventing Foreign Matter Contamination Through Integrated Control
【Challenges and Causes of Foreign Matter Contamination】
Foreign matter contamination in lost-wax casting is one of the primary causes of quality defects and post-processing failures, resulting from the inclusion of unwanted particles or residues inside or on the surface of castings.
Key causes include impurities during metal melting, residues within the mold, and incomplete removal of wax or mold materials.
【KOBAYASHI CASTING's Measures and Process Control】
KOBAYASHI CASTING addresses foreign matter contamination issues with the following technologies and processes:
- **Complete removal of wax residues using automatic dewaxing equipment (autoclave)**
- Suppression of impurity generation through stable melting using medium and high-frequency induction furnaces
- Thorough elimination of moisture and foreign matter residues through mold drying and heating management
- Confirmation of material purity for every lot using a metal component analyzer
- Quality management system compliant with ISO9001:2015 and PED certification
【Benefits of Improved Quality and Reliability】
This enables KOBAYASHI CASTING to provide reliable, high-quality lost-wax products even for medical, machinery, and semiconductor applications.
