Two decades dedicated to precision power transmission—quietly and reliably serving as a foundation behind the industries we support.
In 2006, Mr. Guo Siyan founded Wolfer in Guangzhou. We began as a small workshop focused solely on manufacturing gears from customer drawings. Twenty years later, we remain true to that starting point: every component begins with the customer's drawing, and every gear is made with care. Over time, our customer base has expanded, our machining equipment has evolved, and our inspection laboratory has advanced. What has never changed is our respect for every drawing, our uncompromising pursuit of precision, and our commitment to consistent delivery.

Real customer outcomes, verified in the field
Recent project cases below. Customer names are anonymized by industry, but every figure is on record. Engineering-led, built to drawing, every lot inspected before shipment.
Corrugated-board packaging machines
A major corrugated-board printing equipment maker had long fought tooth skipping and rapid wear on its printing-drive racks. After switching to Wolfer Grade-6 ground racks, running noise dropped as well, and the customer named Wolfer a "core inspection-waived supplier".
- 3× the service life of the previous solution
- 3×
Running noise down 5 dB
- Gear Racks
- Custom gears
CNC gantry positioning systems
Upgraded the feed system of a gantry machining center with ground-grade gear & rack and supported on-site backlash tuning. Data independently measured by the customer on site.
- 0.015 mm positioning accuracy over full travel
- 0.015mm
±0.005 mm repeatability
- Ground gear racks
- Helical pinions
Localization of a Japanese OEM spiral bevel gear
A CNC machine builder had been unable to localize Japanese-imported spiral bevel gears because of tight positioning-accuracy requirements. Wolfer's custom spiral bevel gear sets matched the imported accuracy while cutting purchasing cost significantly.
- −56% cost vs. imported parts
- −56%
Accuracy on par with Japanese OEM parts
- Spiral Bevel Gears
- Custom engineering

Testimonials
Real feedback from the production line
“After more than a decade with Wolfer, their products have been consistently reliable — and their sales engineers' advice at the selection stage has saved us from design detours more than once. A true problem-solving partner.”
Purchasing Director
Automation equipment company
“We switched from an imported brand to Wolfer's high-precision gear racks. Accuracy targets were met, per-batch purchasing cost dropped 35%, and lead time went from 12 weeks to 4. Our supply chain is more secure now.”
Technical Manager
Laser cutting machine manufacturer
“Their locking assemblies and couplings have performed outstandingly under the heavy shock loads of our ceramic presses — three years, zero failures — and after-sales response is always prompt.”
Equipment Manager
Building-materials machinery company
“Wolfer's quality, delivery and service are beyond reproach. Purchase cost runs slightly higher, but counting the operating costs they save us, total cost is still lower.”

Import replacement is not only about unit price; validation cost, lead time and reorder risk matter too.
