Company News | Technical & Commercial Meeting with HA Co., Ltd. in Siheung, Korea (March 18, 2026)

Factory Tour and Process Exchange

During the visit, the HA team introduced their production environment and quality control routines, enabling both sides to review application requirements in a more practical, process-based way. The discussion covered typical performance indicators for foundry sand media, including particle size stability, consistency between batches, and key quality documentation used for incoming inspection.

Quality Topics Discussed

To ensure smoother evaluation and clearer acceptance criteria, the meeting included an in-depth review of quality and technical topics such as:

• Target grade ranges and application scenarios
• Quality control items and reporting format (e.g., grading/PSD, physical properties, and batch traceability)
• Trial approach and evaluation logic for production stability and defect reduction
• Packaging and delivery requirements for sample and bulk supply

Both teams agreed that clear, measurable specifications and consistent documentation are essential for an efficient qualification process.

Pricing and Supply Considerations

In addition to technical topics, both parties discussed commercial factors, including price drivers, order planning, and coordination for future steps. The goal was to build a realistic framework that balances performance expectations with total operating cost considerations on the customer side.

Next Steps

Following the meeting, both sides will continue communication to confirm the trial plan, preferred grades, and the documentation needed for evaluation. Any subsequent progress will be based on formal confirmation and standard qualification procedures.
