Product Description

Forged Gear Blanks and Gear Shaft for Heavy-Duty Power Transmission Gear Box – aiming for optimal performance

Our quality-oriented-manufactured gear blanks and gear shaft find applications in a diverse range of heavy-duty machinery, including power transmission gear box, wind power generator, port machinery, mining equipment, oil industry applications, ship building and etc..

These gear box components are designed to withstand demanding conditions and deliver reliable performance.
Our forged gear box components provide following material characteristics:
  – High Strength: withstand torque and heavy loads without deformation.
  – Good Machinability: Easy manufacturability and precision are essential for efficient production.
  – Low Notch Sensitivity Factor: Minimize stress concentration points to prevent premature failure.
  – Good Heat Treatment Properties: Ensure durability and resistance to wear and fatigue.
  – High Wear Resistance: have a long service life even under demanding conditions.

Our Commitment For Quality

Quality is Tiangong Forging’s commitment to continuously drive the company and customers forward.
To us, quality means taking care of each customer with a professional and proactive attitude. We have been a CHINAMFG in the forging industry’s adoption of the ISO 9001-2015 standard and are proud that our technology has gained major industry recognition over the years.

Our quality assurance laboratory has a variety of advanced testing equipment to ensure that the metal composition, mechanical properties, hardness,

ultrasonic flaw detection, metallography, product dimensions, etc. of the product can meet the standards required by customers.

After customer confirms the order, we will establish a detailed quality control plan for all customers’ products. And after obtaining the customer’s consent, it is strictly implemented throughout the production process.

All products are shipped with a detailed product quality certificate, which lists various test results, including raw material alloy chemical composition, mechanical properties, appearance inspection, ultrasonic flaw detection, actual heat treatment temperature control chart, metallographic photos, quenching permeability test, etc.
