CUSTOM INVESTMENT CASTING SERVICES
Comprehensive Custom Investment Casting Solutions
At Taiyuan Simis Investment Casting Co., Ltd. Our custom investment casting services provide solutions for a broad spectrum of industries, including aerospace, automotive, railway, mining and construction, engineering machinery, agriculture, marine and consumer electronics. Besides custom services, we offer OEM production, partnering with our clients to meet their unique application requirements and managing the entire manufacturing process from initial design to final product.
Our manufacturing infrastructure includes two adjacent investment casting facilities specializing in carbon/alloy steel and stainless steel, respectively, and a dedicated iron casting foundry. Our carbon/alloy steel investment casting facility utilizes a cutting-edge rapid-drying silica sol investment casting process to enhance quality and shorten lead times. Both plants are highly automated and fully equipped for in-house tooling, CNC machining, heat treatment, surface treatment, and comprehensive testing and inspection.
Our 9-Step Investment Casting Services
Our custom investment casting services are designed for efficiency and reliability, providing high-quality results from initial concept to final delivery. This nine-step process includes understanding your needs, design review and optimization, precise tooling creation, sample production and approval, efficient mass production with regular updates, necessary finishing and secondary operations, rigorous quality control, and careful packaging and shipping, along with ongoing support.
Step 1: Understanding Your Needs
To initiate your custom investment casting project, we begin with a concise technical consultation. Your drawings or concept initiate our analysis of critical technical parameters, including material selection based on required chemical and mechanical properties (strength, hardness, fatigue resistance, composition). We clarify secondary operation needs – machining, surface treatments and heat treatment upfront. Our streamlined consultation guarantees efficient understanding of your project requirements and optimal casting outcomes.
Step 2: Design Review and Optimization (DFM)
As part of our custom investment casting services, our experienced engineers perform Design for Manufacturability (DFM) analysis to proactively identify and solve potential manufacturing challenges. Not only does this optimize your design for investment casting, but it effectively prevents common defects before production. DFM considers factors like shrinkage, porosity, distortion, mold fill, and tooling complexity. We address these by optimizing wall thicknesses, gating, risering, ribbing, venting, and part geometry, and by simplifying tooling design.
Step 3: Tooling and Pattern Creation
Our custom investment casting services feature complete in-house tooling. Based on the DFM-approved design, we manufacture tooling using advanced CNC machining and precision techniques to create highly accurate dies, molds, and core boxes. Our in-house approach provides full control over tooling quality, tolerances, and lead times. These precise tools then produce wax patterns that faithfully replicate the intended part geometry, including intricate details.
Step 4: Sample Production
Prior to full production, we create sample castings using new tooling to proactively prevent issues and maintain casting integrity. These prototypes undergo rigorous inspection and testing to identify defects (shrinkage, porosity, etc.), verify dimensional accuracy, and validate material properties when needed. This crucial phase allows us to correct tooling or process issues, minimizing rework and guaranteeing production success.
Step 5: Sample Inspection and Approval
We then provide the sample castings to you for your thorough review and approval. This crucial step in our investment casting services process gives you the opportunity to meticulously inspect the prototypes and confirm that they meet your precise specifications and requirements. We encourage you to examine the samples for dimensional accuracy, surface finish, and any other relevant characteristics. Detailed inspection reports from our internal quality control are also provided.
Your feedback is invaluable, and we are happy to make any necessary adjustments to the tooling, casting process, or even the design itself based on your input. Only after receiving your formal written approval do we proceed to mass production, ensuring that the final product meets your expectations.
Step 6: Mass Production and Progress Updates
Mass production begins upon sample approval as part of our core service. We maintain transparent communication throughout, providing regular updates including production schedule, progress reports (milestones/deviations), challenge alerts with solutions, and quality checks.
Step 7: Finishing and Secondary Options
Our custom investment casting services offer bespoke solutions encompassing various finishing and secondary operations. Based on your initial consultation needs, we provide heat treatments to optimize mechanical properties like strength and wear resistance. We also offer surface treatments to enhance corrosion resistance, finish, and aesthetics. For critical tolerances or complex features, precision CNC machining is available. These finishing and secondary operations, defined during initial consultation, overcome manufacturing challenges to deliver your ideal final product.
Step 8: Quality Control and Inspection
Quality is top priority throughout our ISO 9001 accredited custom investment casting services. Our comprehensive QC system covers every production stage, from raw material verification to shipment, facilitating specification and industry standard adherence. Quality control begins with incoming material inspection and continues through in-process checks of casting parameters (mold integrity, pouring temperature, cooling rates). Post-casting, we perform dimensional inspections using calipers, micrometers, CMM, and other precision tools, especially for complex parts. We also employ Non-Destructive Testing (NDT) – visual, DPI, MPI, X-ray, UT – to detect flaws. Material Testing (tensile, hardness, chemical, microstructural analysis) is performed when needed to validate properties.
Step 9: Delivery and Support
As the final step, we package and ship your finished castings to guarantee safe, on-time arrival, ready for your product integration. Appropriate, customized packaging protects castings from transit damage. We use trusted carriers and offer various shipping options, including expedited service for urgent projects. We also provide full documentation (packing lists, shipping details, certifications). Beyond delivery, we offer ongoing support and are available for any questions on current or future projects. We provide seamless delivery and ongoing support as a standard part of our custom investment casting service.
