Italian Customer Visits Haitian Casting: Wear-Resistant Casting Technology, Material Testing and Quality Control

On October 14, Haitian Casting welcomed a customer from Italy for a factory tour and technical discussions. The visit focused on wear-resistant castings, material properties, casting processes, heat treatment, quality inspection, and new product development. During the tour, the customer gained a closer understanding of Haitian's production processes and quality management practices. Both teams also exchanged views on technical requirements, process validation, and plans for future cooperation.

For wear-resistant castings, product performance depends not only on material selection but also on chemical composition, casting process control, heat treatment, dimensional accuracy, and final inspection. The discussions focused on material performance, inspection standards, process optimization, and manufacturing consistency, establishing a practical basis for the next stage of product validation and cooperation.

Factory Tour: Understanding Casting Processes and Production Management

During the factory tour, the customer visited Haitian's production facilities and learned about its resin sand casting operations and related process management practices. Both teams discussed production workflows, shop-floor management, process consistency, and quality control for wear-resistant castings.

Consistent casting quality requires coordinated control of equipment, operating procedures, personnel, and process parameters. Maintaining a stable production team, following standardized procedures, and strengthening process management help reduce production variation and support reliable product quality and delivery.

The teams also discussed production planning and machining arrangements for future orders. During the initial cooperation stage, selected machining operations for small-batch orders may be outsourced according to product requirements, with clear specifications for machining scope, inspection, and delivery. As order volumes increase, Haitian will evaluate investment in machining equipment and opportunities to expand its in-house machining capabilities.

Material Properties and Hardness Control: Validating the Heat Treatment Process

A key topic of the technical discussion was the hardness softening issue identified in products made from J26 material. Both teams plan to investigate the potential causes and evaluate the annealing process. The next steps will involve testing relevant process parameters and validating the results before confirming an appropriate manufacturing solution.

For wear-resistant castings, material performance needs to be assessed alongside chemical composition, casting conditions, and heat treatment. Hardness is an important indicator of product properties, but it must be evaluated against the agreed technical requirements and, where applicable, alongside other inspection results.

Through material analysis and heat treatment process validation, the teams aim to identify the factors affecting product hardness and improve process stability. The final process parameters will be determined based on test results to ensure that the products meet the technical requirements agreed upon by both parties.

Material Testing and Quality Inspection: Establishing Clear Acceptance Standards

Material testing and quality inspection were also important parts of the discussion. Both teams reviewed the need to confirm product inspection specifications and process documentation before production. Once finalized, the mutually approved documents will serve as the common reference for manufacturing, quality inspection, and product acceptance.

Depending on the product and its technical requirements, the inspection plan may include chemical composition analysis, hardness testing, dimensional inspection, visual inspection, and other applicable tests. For products requiring material or heat treatment adjustments, the teams will also review process validation results and final inspection data to verify compliance with the agreed specifications.

Chemical composition analysis helps verify whether a material meets the specified alloy requirements. Hardness testing checks compliance with the agreed hardness range, while dimensional and visual inspections help confirm that the finished parts meet the relevant specifications. The actual inspection items, methods, and acceptance criteria will be determined according to the product's technical documentation and the requirements confirmed by both parties.

Haitian's mining wear parts solution page provides further information about its inspection capabilities, including material composition analysis, hardness testing, and dimensional measurement.

By confirming inspection standards in advance and implementing appropriate quality controls throughout production, both parties can reduce misunderstandings during inspection, avoid unnecessary rework, and establish consistent acceptance criteria for trial orders and subsequent batch production.

3D Sand Printing: More Flexibility for New Product Development

The teams also discussed the potential use of 3D sand printing for new product development and small-batch production. Conventional pattern and tooling development typically requires upfront investment and preparation time. In comparison, 3D sand printing can produce sand molds and cores directly from digital models, offering greater flexibility for products involving multiple designs or small trial batches.

Haitian will assess the suitability of 3D sand printing based on each product's geometry, casting process requirements, technical feasibility, and overall cost. Where appropriate, this approach may reduce initial tooling investment, improve flexibility during prototype development, and make design adjustments easier to implement.

The manufacturing method will be selected according to the requirements of each project, taking product structure, casting feasibility, and cost into account.

Small-Batch Validation and Step-by-Step Production Expansion

For future cooperation, both teams discussed a phased approach based on the principle of validating one product before gradually increasing its production volume. Standard products will be prioritized for initial small-batch trials, with evaluations covering material compliance, casting quality, manufacturing processes, delivery performance, and coordination between the two teams.

An initial validation period of six months was discussed, with the possibility of adjustment depending on actual progress. If product quality, delivery performance, and cooperation meet the agreed requirements, the validation period may be shortened. Once a product passes validation, its order volume can be increased gradually before additional products enter the trial process.

The teams will also continue discussions on the framework cooperation agreement, supplier quality assurance agreement, confidentiality agreement, and exclusivity agreement. These documents will help clarify the scope of cooperation, technical requirements, quality responsibilities, and obligations on both sides.

Building Long-Term Cooperation Through Material Control and Quality Assurance

The October 14 visit provided an opportunity for both teams to discuss practical manufacturing requirements in detail, from material properties and hardness control to heat treatment, casting process management, and final product inspection.

Haitian Casting will continue working with the customer on J26 material process validation, confirmation of inspection standards and process documentation, initial product trials, and machining arrangements. By strengthening material testing, heat treatment validation, casting process control, and inspection consistency, both teams aim to establish a reliable technical and quality foundation for future cooperation.
