In recent years, Ningbo Bessermax Power Technology Co., Ltd. has placed significant emphasis on standardization efforts. By participating in drafting national standards related to investment casting, the company promotes the industrialization of technological innovations, achieving standard-driven technological advancement and quality improvement through standardization.
Following its participation in drafting national standards GB/T 32252-2024 "General Technical Guidelines for Investment Casting Processes" and GB/T 32251-2024 "Pollution Control in Investment Casting Processes," the company has now contributed to two additional national standards: GB/T 45164-2024 "Classification and Nomenclature of Defects in Investment Castings" and GB/T 45167-2024 "Visual Inspection Method for Surface Quality of Investment Cast Steel, Nickel Alloy, and Cobalt Alloy Castings." Recently, the company actively participated in completing the English translation of GB/T 32252-2024 "General Technical Guidelines for Investment Casting Processes."
I. National Standard Development and Industry Leadership
GB/T 32252-2024 "General Technical Guidelines for Investment Casting Processes" responds to advancements in casting technology and increasing market demands for castings. It clarifies the design, production, and management of investment casting processes, establishing principles of applicability, efficiency, low consumption, near-net shaping, clean production, and safety. The standard regulates the selection and use of raw materials, casting process review, production processes, and waste recycling requirements.
It enhances the standardization, operability, and traceability of casting technical documentation, providing reference guidelines for process design and management in the investment casting industry. This standard plays a crucial guiding and supporting role in helping foundries continuously improve processes, optimize product structures, and reduce environmental pollution and occupational hazards during production.
Bessermax has introduced investment casting simulation software, utilizing computer numerical simulation technology to design and optimize casting processes. This improves casting yield rates, reduces production costs, and shortens prototype development cycles. The company has also installed two fully automated shell production lines and fourteen CNC machining centers, extensively implementing industrial robots in casting workshops. By replacing manual operations in hazardous and noisy processes with robots, the company enhances casting quality consistency, reduces worker injuries, improves the production environment, and increases efficiency.
II. Intelligent Technology and Green Production Practices
Through the revision of GB/T 32251-2024 "Pollution Control in Investment Casting Processes," the company promotes the broader application of environmentally friendly materials in the casting industry, driving cost reduction, efficiency improvement, and technological progress across the sector. The standard encourages the adoption of new eco-friendly processes to minimize pollutant generation and guides the industry in implementing advanced environmental technologies to address issues like dust and emissions.
The company adopted silica sol rapid-drying technology early on, effectively reducing material and energy consumption while decreasing harmful gas emissions. Additionally, Bessermax utilizes advanced vacuum melting and heat treatment equipment to achieve green and sustainable casting production.
III. Full-Service Capabilities and Market Recognition
By participating in drafting GB/T 45164-2024 "Classification and Nomenclature of Defects in Investment Castings," the company strengthens research on casting defects and their elimination. This standard provides detailed descriptions and reference images of various defects, establishing a unified classification and naming system for investment casting defects.
It prevents disputes caused by inconsistent defect terminology and offers technical personnel clear guidelines for defect identification, root cause analysis, and preventive measures. This helps reduce scrap rates and enhances the quality and efficiency of the investment casting industry. The standard fills a gap in defect classification and terminology for investment castings, providing reference criteria for product design, manufacturing, and inspection. Through defect analysis, production processes can be improved, leading to higher technical standards and product quality.
IV. Breakthroughs in Quality Control Standards
Through participation in drafting GB/T 45167-2024 "Visual Inspection Method for Surface Quality of Investment Cast Steel, Nickel Alloy, and Cobalt Alloy Castings," the company has standardized visual inspection methods for these materials. The standard evaluates whether non-machined surfaces have properly cleaned gates and risers, and identifies critical defects such as cracks, holes, penetrating cold shuts, shrinkage porosity, and inclusions that cannot be removed by machining.
It also assesses the cleanliness of non-machined surfaces regarding flash, parting lines, shell residues, and core remnants, while specifying acceptable limits for surface pits, gas holes, sand inclusions, and slag distribution. This standard provides essential references for casting design, production, and inspection, significantly contributing to the high-quality development of China's investment casting industry.
