The casting material ranges from HT250 to HT350, QT400-18 to QT700-2, RuT260 to RuT420, and all other kinds of alloy iron casting.
Coated sand casting components have been widely used in various industries due to their high precision, complex structural forming ability, and excellent surface quality. We provide hydraulic solutions such as gear pumps, multi way valves, solenoid valves, hydraulic motors, etc. for the engineering machinery, agricultural machinery, coal mining machinery, metallurgical and chemical industries.
The materials used include gray cast iron, ductile iron, and nodular cast iron
All of these materials are designed to ensure lightweight structures, enhance wear resistance, and reliability under extreme environmental conditions.
Q1: What is the highest precision that Film coated sand shell casting can achieve?
A: Film coated sand shell casting can achieve ISO 8062 CT9 level precision (key dimensions ±0.3mm).
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 film coated sand shell casting 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: Use industrial endoscopes for 100% full inspection to ensure the quality of the internal cavity.
● 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 / phosphating/nitriding / PVD coating (hardness up to HRC65)
● Assembly and inspection: Equipped with air tightness testing and dynamic balance testing equipment.
The surface of each casting is smooth and clean, free from bumps, pores, and sand holes.Every product undergoes 100% inspection before packaging to ensure flawless quality.
1. Precision Endoscopic Testing: Advanced endoscopic instruments are used to detect internal defects and guarantee the reliability of the oil circuit.
2. Comprehensive Material Testing: Casting test bars are subjected to tensile, elongation, and metallographic (microstructure) analysis to ensure mechanical strength and material integrity.
Conventional packaging is wooden box or wooden pallet and wrapped with plastic film.
