Quality Control
1) Checking the raw material after they reach our factory------- Incoming quality control ( IQC)
2) Checking the details before the production line operated
3) Have full inspection and routing inspection during mass production---In process quality control(IPQC)
4) Checking the goods after they are finished---- Final quality control(FQC)
5) Checking the goods after they are finished-----Outgoing quality control(OQC)

Material inspection: Before each batch of alloy steel is stored, its composition and performance are tested to ensure the impact resistance at the source.
High-temperature hot forging: High-temperature forging refines the microstructure of the metal, enhancing the drill rod's toughness and fatigue resistance.
Coarse turning forming: Turning removes the excess material, processing the basic shape and key positioning dimensions.
Heat treatment: Independently adjusting process parameters to balance hardness and toughness, preventing fractures and wear resistance.
Precision processing: Precise control of tolerances through turning, milling, and grinding to fit the assembly of various types of hydraulic breaker hammers.
Multiple inspections: Comprehensive inspection of dimensions, hardness, and surface defects, eliminating defective products before shipment.
Finished product packaging: Cleaning and protection before storage, supporting rapid delivery of large orders and custom orders.

FAQ
- What are the main differences between open-die and closed-die forging?
- Open-Die forgings are produced between flat or simple-shaped dies, ideal for large, simple shapes like bars, shafts, and rings. Closed-Die forgings are pressed into precision-molded dies, producing complex, near-net-shape parts with excellent dimensional accuracy, ideal for high-volume components like automotive parts.
- Can you work from my CAD drawing or sample?
- Absolutely. We specialize in producing custom forgings from your technical drawings, 3D CAD models (STEP, IGES), or physical samples. Our engineers will conduct a free Design for Manufacturing (DFM) analysis.
- Do you provide machined, ready-to-install forgings?
- Yes. We offer a complete 'Forging + Machining' turnkey service. We can deliver a fully finished component to your exact specifications, saving you time and managing your entire supply chain.
- What certifications do you hold?
- We are ISO 9001:2015 certified. We also manufacture to industry-specific standards such as AS9100 (Aerospace) and PED (Pressure Equipment Directive). Material and test certificates are provided with every order.
- What is your typical lead time?
- For standard custom forgings, lead time is typically 4-8 weeks after final design approval. Prototype lead times can be expedited. We provide a detailed schedule with your quotation.
- Why choose the Shengao product?
- We sheng ao have our own plant Weifang Shengao Machinery Co., Ltd, therefore, we can surely promise the quality of every product and provide you comparable price. Quality First, Price Best, Service Foremost! We assure you of our best services at all times!
