Examination on Suppliers
In our factory, thorough inspections are conducted on common casting parts, spare parts, and standard components. For instance, 2-ton casting parts undergo an intensive strength test, with 3 Siamese test bars prepared for each part. Only those that pass the stringent test are deemed qualified for use, ensuring the highest quality standards. Additionally, key components undergo on-site inspections, such as sending quality testers to suppliers’ factories for meticulous flaw inspections on every shaft. We only place orders for components that meet our strict quality criteria, guaranteeing excellence in every aspect of our manufacturing process. Trust in our commitment to quality assurance for reliable and superior products. Choose us for unmatched precision and quality in every component.
Intensity Inspection
Following the heat treatment process, our quality control department conducts meticulous configuration and intensity inspections on all spare parts. Our intensive intensity testing employs both tensile and torsion tests to thoroughly assess the tensile and torsional capabilities of each component. Trust in our rigorous quality control measures to ensure the durability and performance of our spare parts. Choose us for precision and excellence in every step of the manufacturing process.
Metallographic Analysis after Heat Treatment
Following the intensity test, our qualified metal spare parts, including shafts, stainless casting parts, and standard components, undergo a crucial second metallographic analysis. This analysis assesses the metallographic structure after heat treatment to ensure it meets stringent quality standards. Only those that pass this rigorous analysis proceed to the machining stage, guaranteeing top-notch quality. Any parts that do not meet the criteria are set aside. Trust in our meticulous processes to deliver machined metal components that meet the highest quality standards in the industry. Choose us for precision and reliability at every step of the manufacturing process.
Machining of spare parts
The manufacturing workshop ensures precise processing of spare parts through adherence to rigorous technological procedures, utilizing specialized facilities under the guidance of the R&D and technology departments. Stringent supervision and inspection by the quality control department guarantee that only qualified parts progress to the next assembling procedure.
Composition Analysis of Raw Materials
The Material Research Laboratory oversees the procurement of materials for our company. Our Physical and Chemical Laboratory conducts thorough analyses on raw materials for casting parts and semi-finished products. Utilizing specialized machines, we perform chemical composition analyses on various materials like cast iron, carbon steel, stainless steel, rubber, etc. All materials undergo selective inspection upon arrival at the factory, ensuring that only qualified materials proceed to the machining phase.
Metallographic Analysis of Raw Materials
The Material Research Laboratory creates comprehensive metallographic analysis charts for various metal materials. Our Physics and Chemistry Laboratory performs metallographic analyses on metal components such as shafts, stainless steel casting parts, and standard components. These analyses assess whether the non-metal impurity levels meet industry standards and ensure that the metallographic structure aligns with the required quality standards.
Rough Machining and Heat Treatment
Following the successful completion of metallographic and composition analyses, spare parts undergo precise rough machining and inspection. Our Heat Treatment Workshop, guided by technical procedures and specifications developed by the Material Research Laboratory, expertly conducts heat treatment on these spare parts. Specialists oversee and ensure the quality of the heat treatment process.
Inspection of spare parts
Following a specific technological process, our Quality Control Department conducts initial and in-process inspections during machining, followed by selective examinations post-machining. Small batch productions undergo comprehensive inspections, ensuring that only qualified parts proceed to the assembly shop for the next phase.
Product Assembly
Adhering to a specific technological process, the Assembly Shop utilizes specialized industrial equipment for assembling spare parts, guided by the expertise of the R&D and Crafts sectors. Following assembly, rigorous supervision and testing by the Quality Control Department ensure quality. Only the qualified products proceed to the test center for comprehensive performance testing.
Performance Test
The Test Center oversees product performance tests based on specified testing criteria and customer-specific requirements. Comprehensive evaluations, including pump hydraulic performance, motor performance, noise, and vibration tests, yield results sent to the Quality Control Department. Only products meeting the stringent criteria are entrusted to our customers, ensuring top-notch quality.
