17CrNiMo6 18CrNiMo7-6 Hollow Shaft Gearbox Hollow Shaft Gear Forging Manufacturer
Guangda can produce forged thick wall hollow cylinder and sleeve in various custom configurations according to customer requirements. Seamless forged hollow is ideal for high stress applications and harsh environments due to its durability, strength and corrosion resistance. The hollow can be manufactured not only as a straight cylinder, but also as an infinite variety of suction and internal diameter, including a cone.
In addition, all downstream processing, including heat treatment, machining and NDT, is available upon request. Our team will work with you to utilize our capabilities to minimize material waste and reduce process inefficiencies.
Forged Sleeves / Hollow Shaft Technology
We offer complete heat treat capabilities including anneal, normalize and temper, solution treatment, quench (polymer and water) and temper and stress relieve. Our testing and inspection capabilities include chemical analysis, mechanical testing, nondestructive testing including Level III ultrasonic, penetrant testing, and magnetic particle testing.
Forged Sleeves / Hollow Shaft forging procedure
Forging process flow quality control: Raw material steel ingot into warehouse(test the chemical content) → Cutting→ Heating(Furnace temperture test) → Heat treatment after forging(Furnace temperture test) Discharge the furnace(blank inspection)→ Machining→ Inspection(UT,MT,Visal diamention, hardness)→ QT→ Inspection(UT, mechanical properties, hardness, grain size)→ Finish machining→ Inspection (dimension)→ Packing and Marking(steel stamp, mark)→ Storage Shipment
High-precision dimensional tolerance;Excellent mechanical properties;Produce different dimension based on customer’s requirements;Advanced manufacture equipments and inspection devices;Excellent technical personality;Control the production procedure strictly;Pay attention on the package protection;Quality full service.
