Our Services
Quality Castings for Diverse Industries
Taiyuan Simis Investment Casting Co., Ltd. is a professional investment casting manufacturer in China, specializing in producing components with intricate details and precision. Our casting process is particularly well-suited for industries such as aerospace, railway, automotive, mining and construction machinery, agricultural machinery, energy sector, and medical devices, among others. We offer parts with smooth finishes and high dimensional accuracy.
Silica Sol Investment Casting Expertise
Over the years, we’ve significantly improved our silica sol investment casting techniques. A notable improvement is replacing water glass binders with silica sol binders, enhancing both the working environment and the quality of our castings. We’ve also reduced the drying time for silica sol shells from eight hours to one hour per layer, increasing production speed and shell strength.
Our use of silica sol casting process now extends beyond stainless steel to include carbon steel and various alloy steels, supporting cast parts up to 50kg and reducing costs. Our fully automated shell-making process ensures precision and reduces variability in production, with up to eight layers of shells managed by automated units. These innovations also enhance operational efficiency and minimize our environmental impact.
Comprehensive Custom Casting Solutions
Taiyuan Simis is more than just an investment casting manufacturer. We also provide sand casting, shell mold casting, die casting, and precision machining services, offering a complete suite of metal casting solutions. Our in-house tooling and rapid prototyping capabilities further enhance our ability to deliver tailored solutions, whether for custom designs or OEM products. With an experienced engineering team and robust production capabilities, we ensure high-quality metal castings at competitive prices, precisely meeting the unique requirements of each customer.
Industries Served
We provide precision castings that serve a diverse range of mechanical sectors. With over 40 years of expertise as a seasoned investment casting manufacturer, we take pride in providing to clients in engineering machinery, agriculture machinery, building machinery, transportation, automobile, locomotive, rail transit, the aerospace domain, and more. Our team of accomplished engineers and dedicated professionals ensures the production of top-tier castings customised to meet your precise requirements, establishing us as your trusted ally in the field.
Casting Materials Expertise
As a professional Chinese investment casting foundry, we provide versatile material solutions to meet diverse customer needs. We cast a wide range of ferrous and non-ferrous materials, including various grades of carbon steel, alloy steel, stainless steel, high-nickel steel, high-manganese steel, and high-strength steel, as well as aluminum alloys, superalloys, gray cast iron, ductile cast iron, zinc, bronze, and brass. Our focus on precision and quality ensures that our castings conform to rigorous industry standards, making us a reliable partner for your manufacturing requirements.
Alloy Steel
We provide alloy steel castings for demanding applications in industries like aerospace, automotive, and heavy machinery. Alloying elements such as manganese, nickel, chromium, and molybdenum enhance properties like strength, toughness, wear resistance, and hardenability. This allows us to offer grades like 4140 (for high strength and toughness), 8620 (for carburized components requiring wear resistance), and high-manganese steel (for exceptional wear resistance and work hardening).
Carbon Steel
For general-purpose applications, we offer cost-effective carbon steel castings in various grades categorized by carbon content, each providing a different balance of strength and ductility. From highly ductile and weldable low-carbon steels to high-carbon steels offering high hardness and abrasion resistance, we can meet diverse needs. Carbon steel castings are valued for their cost-effectiveness, good machinability and weldability, and overall versatility.
Stainless Steel
For applications requiring superior corrosion resistance, high strength, and durability, we offer stainless steel castings in various grades: austenitic (304, 316, 316L—316/316L are particularly resistant to pitting and crevice corrosion), ferritic, martensitic, and duplex. These are ideal for harsh environments and hygienic settings (food, beverage, pharmaceutical, marine, railway) and offer resistance to temperature and pressure (depending on the grade).
Cast Iron
Our cast iron castings are a cost-effective choice, offering a combination of good compressive strength, wear resistance, and vibration damping. Our range includes gray cast iron, prized for its excellent machinability and ability to dampen vibrations; ductile cast iron (nodular cast iron), which provides significantly improved strength and ductility compared to gray iron; and austempered ductile iron (ADI), offering exceptionally high strength, toughness, and wear resistance, making it suitable for highly stressed applications.
Aluminum Alloy
For lightweight, corrosion-resistant, and strong solutions, we offer various aluminum casting grades. Common grades include A356, with excellent castability and strength; A357, with enhanced strength and heat treatability; A380, versatile and widely used; A383, with improved die filling and hot tearing resistance; and A360, with excellent corrosion resistance and suitable for thin walls. These alloys offer a balance of performance and cost-effectiveness for various industries.
