YKM Group has a complete set of advanced Metal Mesh Raw Material Inspection instruments and equipment, which is capable of testing the physical & chemical properties of the raw material. The main inspection instruments are infrared carbon-sulfur analyzer, radioactive X/Y dose rate monitor, X-ray fluorescence spectrum, laser beam diameter measuring instrument, microhardness tester, universal tensile testing machine, etc. These instruments are capable of testing and monitoring the radioactivity, metallic elements & chemical components, mechanical property, ovality, internal structure, microhardness, and many other parameters. All plain wire mesh and woven wire mesh testing instruments have been calibrated by the professional organization from a third party.

To ensure the precision and standardization of the metal mesh raw material inspection, YKM International LLC. has the standard operation procedures of raw material purchasing, inspection, warehouse entry, and the operation of the inspection instruments, which are strictly under control and undergo regular maintenance and for these all reasons YKM Group is ranked as the Top Woven Mesh Manufacturer. All inspection operators should pass professional training. For special inspection items, the operators are supposed to be certified by National Professional Organization.

The various standard wire mesh samples from each lot have been verified via ERP system plus logistics management, which have assured the stability of raw material quality, traceability of raw materials and testability to record samples from each lot.

The procedures of raw material testing include the radioactivity, internal structure level, chemical property, wire diameter ovality mechanical property, and wire hardness.

Only the above inspection passed items are proved qualified and the warehouse-in and warehouse-out procedure can be done. For unqualified raw materials, it is managed according to the Unqualified Products Management Procedures, the raw material testing & management procedure is completely carried out per the requirement of ISO9001 and TS16949.

Portable Radiation Detector

Under the guidance of experts in NIM (approval by CIPM and BIPM), YKM Group, Top Woven Mesh Manufacturer introduced radiological detection equipment for inspecting raw material at the end of 2007 and manufactured wire mesh products inspection to protect operators from the hurt caused by radioactive contaminants mixed in iron or steel material.

Innov-X System Handheld XRF Analyzer

The Innov-X System handheld XRF Analyzer is utilized for metal chemical analysis. It can exactly analyse chemical components within 30 seconds. Permanent testing records are preserved. It can guarantee the traceability of raw material quality.

Infrared Carbon-Sulfur Analyzer

With the condition of rich Oxygen and high temperature, the carbon and sulphur inside the metal can be transformed into CO2 and SO2. After being absorbed by infrared radiation and dealing with artificial intelligence, it will show the exact carbon and sulphur sensitively and composition quickly. This method is used to distinguish materials 304&304L, 316 &316L, and so on.

Photodosimeter for wire diameter

It is a high-precision non-contact online measurement system with optical, high-speed data acquisition system and microprocessor technology. Measure range of wire diameter ranges from 0.01-2mm and the tolerance is +/-0.0001mm.

Electrical Universal Testing Machine

This instrument is utilized to test the material's mechanics performance, like elongation, tearing, peeling, cutting, bending, compressing, etc. It is capable of calculating max force, yield strength, average peeling force, max deformation, yield point, elasticity modulus, etc. The maximum measured tensile strength is 50KN; all the related reports can be printed. This testing records can guarantee the traceability of the raw material quality.

Microhardness tester

Microhardness tester is an instrument used to measure the indentation capacity of the tested object against another hard object. This machine is mainly used to test the hardness of the stainless steel wire
