Custom Forged Parts from China | Gears, Shafts, Flanges & CNC Machining Suppliers | Factory Quality Assurance

At our factory in China, we specialize in comprehensive flange manufacturing, offering services that include forging, CNC turning, drilling, and heat treatment all under one roof. As leading suppliers in the industry, we can create any flange type according to your specific drawings and requirements, ensuring high-quality production and precision. Trust our expertise for your flange solutions!

    One Roof. One Process. One Quality Standard.

    At Dingxiang Quandesheng Metal Products Co., Ltd., we don't outsource critical steps. We perform forging, CNC turning, drilling, and heat treatment under one roof. This integrated approach gives us complete control over quality, cost, and delivery time.

    How Our Integrated Process Works

    Step 1 – Forging

    Using advanced forging presses, we shape raw materials (carbon steel, alloy steel, or stainless steel) into dense, grain-optimized blanks. Proper forging eliminates internal voids and ensures mechanical strength.

    Step 2 – Fully Automatic CNC Turning

    Once forged, the blank moves directly to our fully automatic CNC lathes. We machine the flange face, bore, and outer diameter to the exact dimensions specified on your drawing. Automation means consistent accuracy and minimal human error.

    Step 3 – CNC Drilling

    Bolt holes are precisely positioned and drilled using CNC drilling machines. Hole alignment, diameter, and count match your drawing – whether standard or non-standard.

    Step 4 – Heat Treatment

    Depending on material and application requirements, we perform normalizing, annealing, quenching, or tempering. Heat treatment relieves internal stresses and achieves the required mechanical properties.

    Dedicated to maintaining the highest standards of technical discipline and product reliability, we provide customers with secure, consistent, and top-tier products. Through unwavering commitment and proactive development, we produce high-caliber products that fulfill client requirements and ensure superior service. Interested in our products?

    Frequently Asked Questions
    What are the benefits of having forging, CNC turning, drilling, and heat treatment under one roof?

    By keeping all manufacturing processes in-house, we eliminate outsourcing delays and maintain complete control over quality standards, production costs, and overall delivery timelines.

    What materials do you use for manufacturing custom flanges?

    We work with a variety of high-quality raw materials, including carbon steel, alloy steel, and stainless steel, to shape dense, grain-optimized blanks suited to your specifications.

    How do you ensure the dimensional accuracy of the machined flanges?

    We utilize fully automatic CNC lathes and CNC drilling machines. This automated machining process ensures that the flange face, bore, outer diameter, and bolt holes perfectly match the exact dimensions of your design drawing with minimal human error.

    What type of heat treatments can you perform?

    Based on your mechanical property and material requirements, we offer several heat treatment options including normalizing, annealing, quenching, and tempering to relieve internal stresses.

    Can you manufacture non-standard flanges based on custom drawings?

    Yes, we specialize in custom manufacturing. You can send us your specific design drawings, and we will handle the entire custom process—from forging to final heat treatment—to meet your exact requirements.
