Our manufacturing process leverages lost wax casting technology to produce precision components from materials such as stainless steel, dual-phase steel, and alloy steel. This method ensures high dimensional accuracy and superior surface finish, making our products ideal for demanding applications in various industries.
We offer a wide range of surface treatment options, including polishing, pickling passivation, sand blasting, electropolishing, grinding, chrome plating, nickel plating, painting, and phosphating. These treatments enhance corrosion resistance, improve aesthetics, and extend the service life of the components, catering to specific customer requirements.
Our advanced machining capabilities include vertical and horizontal machining centers, CNC lathes, and other precision equipment. This allows for efficient production of complex geometries and rapid prototyping during the design phase, reducing the risk of casting defects and ensuring timely delivery.
Quality assurance is a top priority, supported by a complete set of testing equipment. We utilize spectrometers, tensile testing machines, impact testing machines, hardness testers, metallographic microscopes, dynamic balance instruments, coordinate measuring machines (CMM), and X-ray flaw detection machines to verify material properties and structural integrity.
Customization is at the core of our services, with options for tailored designs, specifications, and packaging. We accommodate orders for weights ranging from 0.1 kg to 300 kg, and our monthly production capacity reaches 150 tons. All products are packaged securely, typically on wood pallets, to prevent damage during transit.
