Exhibits
The product-application range includes raw investment castings and finished machined parts such as valve bodies, end caps, valve handles and other valve components, hand tools, plumbing and pipeline fittings, marine hardware, pump parts, CNC machinery parts, industrial equipment parts, food-equipment parts, bicycle components, automotive and motorcycle parts, building hardware, and creative metal artworks. For OEM hardware development, VALVE-TEK PRECISION CASTING CO., LTD. provides custom molding, small quantities for samples, and mass production, with the stated purpose of shortening product-development lead time and improving consistency across the resulting cast or machined components. The same application program uses stainless steel, carbon steel, and alloy steel and combines raw castings with precision-machined components, allowing customers to move from casting to finished machined hardware when post-casting processing is required. The company’s OEM/ODM scope is not limited to one industry: the product categories cover valve, hand-tool, plumbing, marine, pump, machine-tool, industrial-equipment, food-equipment, bicycle, automotive, motorcycle, building-hardware, and creative-metal applications. Sample quantities and mass production are both available within the custom-molding service, so development can begin with trial pieces and continue into repeated production without changing the underlying investment-casting process family. Lost-wax casting is used for parts that need tight tolerances, thinner walls, and surface finishes requiring minimal post-processing, making the process suitable for precision designs where dimensional control and reduced finishing work are important. For wax injection, the company uses casting wax imported from Japan and states that its shrinkage after mold waxing follows the tolerance needed for casting quality, with strict quality control applied to the wax-related production steps. For shell building, casting sands imported from the United States and Australia are selected for high-temperature resistance, and different particle sizes are coated sequentially according to casting size and shape in at least four layers and up to six layers. Steel choices include stainless steel, carbon steel, and alloy steel that comply with American ASTM, European DIN EN, and Japanese JIS specifications for chemical and physical properties, with inspection and testing used to address customer requirements for material performance and reliability. Customer-specified steel chemistry can include stainless steel, carbon steel, and nickel-chromium-molybdenum alloy steel, backed by the company’s investment-casting experience in controlling steel chemical composition. Automotive parts are a suitable investment-casting application because the process can create intricate customized designs with high dimensional accuracy, supporting reliable and efficient performance for application-specific components. For automotive and other OEM parts, the Taiping foundry offers multiple material options and mass production, with service scopes covering casting-solution planning, investment-casting production, mold design, mold-flow analysis, raw castings, machined castings, quality-control programs, packaging, and delivery. Materials for this service include Stainless Steel CF8M and CF8, Carbon Steel WCB, and Alloy Steel, while quality-control options include chemical analysis, impact testing, tensile-strength testing, hardness testing, penetrant testing PT, X-Ray radiography RT, coordinate measurement, and inter-granular corrosion measurement. Inspection options also include high- and low-temperature testing, allowing the quality-control program to be selected according to the customer’s required inspection scope. For drawing-based inquiries, customers can provide 2D or 3D drawings together with material, weight, quantity, and use information, and a quotation can be provided within 3 working days for that route. If a customer has no design drawing, a sample can be provided for the machining engineering team to prepare a drawing and evaluate processing needs, with a quotation provided within 5 working days for that route. Sample development is handled by the R&D design team against requirements for dimensions, material, inspection tests, and processing, after which order quantity and lead time are confirmed, production enters the investment-casting schedule, and finished castings are inspected before delivery or final machining and testing.
Company profile
VALVE-TEK PRECISION CASTING CO., LTD. was established in 1999 as an investment-casting manufacturer based in Taiwan, with Lost-Wax Casting as the production method behind its work in precision cast products. Its casting and machining activities cover valves, pump parts, machine components, hardware, automotive components, and a broader application portfolio that includes OEM castings, OEM machined hardware, creative metal artworks, valve bodies and handles, hand-tool hardware, plumbing and pipeline fittings, marine hardware, CNC machinery parts, industrial and food-equipment parts, bicycle components, automotive and motorcycle parts, and building hardware. The company works with stainless steel, carbon steel, and alloy-steel series and aligns material specifications with standards including ASTM, DIN, EN, and JIS, providing a material base for applications that require different chemical, physical, dimensional, and service-performance characteristics. VALVE-TEK PRECISION CASTING CO., LTD. has adopted mold-flow analysis software to enhance casting services for OEM customers across industrial sectors, adding simulation and casting-solution analysis to its established lost-wax manufacturing and machining capabilities. OEM and ODM are explicit parts of the business model: customers can bring hardware-casting requirements and receive tailor-made solutions that combine casting planning, mold work, material selection, sample development, production, inspection, machining where required, packaging, and delivery. The company operates its own in-house casting foundry in Taiping District, Taichung City, Taiwan, giving its investment-casting service a self-owned manufacturing base for raw castings, machined castings, samples, and mass-production work. Its one-stop casting approach links precision lost-wax production with machining, measuring, material control, testing, and quality programs so that customers can move from drawings or samples through casting and optional final processing within one defined service flow.
