High Torque Worm Gear Shaft for Gearboxes
Our Qimao Metal Manufacturer High Torque Worm Gear Shaft for Gearboxes starts as a certified steel bar. We cut it to length and rough turn the diameter, leaving stock for final grinding after heat treatment. The worm thread is cut using a CNC hob or thread mill. Request a quotation!

High Strength Worm Shaft for Worm Gear Speed Reducers
This High Strength Worm Shaft for Worm Gear Speed Reducers from Qimao Metal Manufacturer is built differently. We start with 42CrMo4 or 20CrMnTi alloy steel, then carburize or induction harden it to 58–62 HRC on the tooth flanks. The core stays softer to absorb impacts. We also grind the thread profile after hardening, not before. That gives you a smooth surface finish and accurate lead angle.

Solenoid Plunger Replacement Armature Core for Hydraulic And Pneumatic Valves
This is a replacement Solenoid Plunger Replacement Armature Core for Hydraulic And Pneumatic Valves from Qimao Metal Manufacturer. The kind you find in hydraulic systems and air lines. The old one stops moving or gets stuck. You pull it out and need a new one that fits exactly. That is what we make. We turn these from stainless steel bar on CNC lathes. The material is usually 430F or 430FR because it responds to magnetic fields. No coating required. The outer diameter gets ground to a smooth finish so it slides inside the valve body without binding. Some have grooves. Some have a stepped nose. We cut whatever your old part looks like. Send us a sample or a drawing.

Precision Steel Hinge Pin For Rotary Control Systems
The Precision Steel Hinge Pin For Rotary Control Systems made by Qimao Metal Manufacturer. It holds two parts together while letting one rotate around a fixed axis. Think of potentiometers, dampers, valve linkages, or throttle controls. The pin needs to be straight, smooth, and consistent. If the pin wobbles, the control signal drifts. We cut these on CNC lathes to tight tolerances. The whole thing comes from one bar of steel or stainless steel. No welded parts. No press fit collars. Just a solid pin that does one job well. It keeps your rotary control accurate for thousands of cycles.
