FAQ
Q1: What is the highest precision that investment casting can achieve?
A: Investment Casting can achieve ISO 8062 CT5 level precision (key dimensions ±0.1mm).
Q2: Do we accept small batch orders? How long does the delivery time usually take for
small batch orders?
A: Yes, of couse. We adopt a flexible production system to ensure a rapid response, utilizing 3D printing of wax models and validating the casting process.
Under normal circumstances, the delivery time for small batch orders will be influenced by the order size, complexity, and
production scheduling. Upon receiving the order, we initiate the production process promptly and maintain close communication with the customer to ensure the timely delivery of precision casting parts that meet the requirements.
Q3: How can we ensure the internal quality of the castings?
A: we employ a four-level inspection system to ensure the internal quality of the castings: Process monitoring: Utilizing real-time detection technology with online X-ray (scanning at 300 frames per minute) for monitoring. Physical and chemical analysis: Using direct reading spectrometers and electron microscopes (inclusion detection accuracy up to 0.01mm level) for analysis. Mechanical verification: Sampling each batch of castings for fatigue testing (number of cycles > 10^7 times). Digital traceability: If special requirements are present, we will add a casting number to each batch of parts, achieving full traceability of the melting batch and process parameters.
Q4: Do we provide one-stop service for subsequent machining/surface treatment?
A: We provide a one-stop integrated service for the entire process chain: Machining support: Five-axis CNC + coordinate grinding machine (positioning accuracy up to ±0.03mm) Surface strengthening: Shot peening / nitriding / PVD coating (hardness up to HRC65) Assembly and inspection: Equipped with air tightness testing and dynamic balance testing equipment.
