Quality
In terms of diamond powder quality control, all of our technological processes are established according to the requirements of ISO9001:2015 quality management system. Implement the requirements of the quality management system to every link. The company is equipped with various instruments for testing raw materials and products, the test includes Ti/TTI test, SEM graph, microscope graph and ICP test and analysis. Each batch of purchased raw materials is tested in strict accordance with the standards, and the qualified storage is recorded in detail. According to the raw materials, the batch number of the produced products is compiled to achieve the traceability of the products. Each batch of goods sent to customers has detailed delivery records and samples, and the raw materials and production inspection status of the products can be found according to the batch number, which can ensure the stability of qualified products and find solutions for customer complaints.
The toughness stability of abrasive diamond powder is critical for tools in application. It influences the working efficiency and service life directly. Shili company persists in consistent quality through toughness testing, to keep the toughness of each batch in a narrow range.
Testing method: Taking some samples to make impact testing, then sieve them, calculate the percentage which remains the original particle, that’s the TI value.
By the means of measuring the particle size and observing the shape by the particle shape analyzer, the particle distribution of mesh diamond powder can be calculated directly under the equivalence principle.
Testing method: Putting the samples under the microscope to analyze the particle size and shape by digital camera and digital image processing technique.
The size of industrial diamond influences the surface finish of the work piece and grinding efficiency directly during the processing. Shili company has strict enterprise standards to ensure the consistency of particle size distribution by controlling it into a narrow range.
Testing method: The size testing is used by electroformed sieves. Sieving the samples by two corresponding sieves, calculate the percentage of abrasives in each sieve, the value is particle size distribution.
ICP Analysis, also called ICP Testing, is performed to identify and measure a range of chemical elements necessary for the analysis of diamond powder samples.
They calculate quantitative and qualitative data that can be included in an ICP test report.we use ICP to test and analysis the impurity of our diamond mesh and micron before delivery.
