Q1: Can you manufacture molds based on our technical drawings or samples?
A1: Absolutely. We specialize in customized ductile iron pipe molds for diameters ranging from DN80 to DN2600. Share your detailed drawings (with material requirements, dimensions, and surface treatment specifications) and our engineers will provide a detailed solution within 24 hours.
Q2: What is the typical lead time for an order?
A2: For standard sizes, lead time for 1pc is 50 days. It will vary depends on the mold size and quantity, contact us for exact timing
Q3: How do you ensure the quality and durability of your molds?
A3: Quality is our core priority, validated through:
Material: Premium 21CrMo10 with superior resistance to thermal fatigue and wear
Process: 7-stage manufacturing control, including:
Secondary forging to eliminate internal defects
Isothermal quenching for consistent mechanical properties
100% ultrasonic flaw detection to ensure zero internal cracks
Certification: ISO 9001:2015 certified factory, with each mold accompanied by a detailed quality report (chemical composition, hardness test, dimensional inspection).
Q4: How do you package the molds?
A4: Packaging is designed to protect molds during long-distance transport:
1. Inner layer: Anti-rust oil coating + moisture-proof plastic film
2. Outer layer: Heavy-duty wooden crates with steel strapping (customized for oversized molds)
Q5: What industries are your molds suitable for?
A5: Our molds are widely used in:
Municipal water supply and sewage systems (ductile iron pipes for underground pipelines)
Industrial pipe manufacturing (high-pressure pipes for oil, gas, and thermal power)
Construction and infrastructure projects (large-diameter pipes for drainage and irrigation)
We also support specialized applications—share your project requirements, and we'll recommend the best mold solution!
