We mainly produce large casting platforms, inspection plates, marking platforms, combination platforms, T-slot plates, machine tool pads, mold pads, engine dynamometer test benches, engine and internal combustion engine test benches, cast iron base plates, benches, floor boring and milling machine auxiliary platforms, various dynamic machinery test bench products, assembly platforms and welding platforms, combination assembly T-slot plates, inspection, marking assembly, riveting and welding, tooling flat plates, boring and milling machine workbenches, coordinate instrument flat plates, mold pads, laboratory basic flat plates, slot iron (ground rail) cushion box cast iron flat plates (platforms) manufactured according to the GB4986-85 standard. The precision levels of the flat plate include 00, 0, 1, 2, 3, and precision planing. The flat plate is made into ribbed plate and box type, and the working surface is rectangular, square, or circular. The working surface adopts scraping technology, and V-shaped, T-shaped, U-shaped grooves, circular holes, long holes, etc. can be machined on the working surface. Cast iron inspection flat plate, cast iron marking flat plate, cast iron riveting welding flat plate, cast iron assembly flat plate, power machinery vibration test bench (also known as groove iron or ground beam, ground rail), cast iron square box, inspection rod, V-shaped iron, granite flat plate (rock flat plate) and other rock measuring tool marking flat plate, riveting welding platformTest platformAssembly platform, inspection platform, marble platform, cast iron work platform combination assembly T-shaped groove flat plate, iron floor, inspection, marking assembly, riveting and welding, tooling flat plate, boring and milling machine platform, coordinate instrument flat plate, mold pad, laboratory foundation flat plate, groove iron (ground rail), square (pad) box machine tool workbench, vibration test bench, foundation platform, landing work platform, detection platform, marking platform, assembly platform, riveting and welding platform, combination platform material is high-strength (HT200-300). The working surface hardness is HB170-240. After two aging treatments (manual aging and natural aging 2-3 years) Make the accuracy of the product stable and have good wear resistance Accuracy shall be carried out in accordance with the standard metrological verification regulations
