OEM & ODM Door Closer Manufacturing for Global Brands

Private Label and Custom Engineering

  • Brand: logo or label, surface finish, private label packaging.
  • Function: spring strength, closing and latching speed, back check, delayed action.
  • Configuration: adjustable back check, standard or hold-open arm, extreme cold hydraulic options.
  • Engineering: 50+ engineers review mold, structure and custom designs.

CE Responsibility and Retesting

Changing a logo or model name does not by itself change test results. A brand that sells under its own name as manufacturer takes on CE and DoP duties, and we provide technical files to help. Colors, finishes and labels usually need no retest. Changes to the valve body, hydraulic chamber or spring usually need re-evaluation, and fire door changes are checked separately.

MOQ, Samples and Lead Time

  • MOQ: generally 300–1,000 pieces by product; medium batches of 300–500 pcs are supported. Custom OEM projects are quoted individually.
  • Samples: sample and freight fees are paid first and credited in full against your first bulk order.
  • Lead time: about 35 days standard; 4–6 weeks for OEM / ODM.
  • Warranty: 5 years.

Frequently Asked Questions About CE Door Closer Manufacturing

What should I include in a bulk door closer RFQ?
Quantity, destination country and target price; door weight, door width, EN power size and installation type; required CE / EN 1154 or project test files; and any logo, packaging, finish or special function needs.
How does OUBAO prevent hydraulic oil leakage?
Piston and cylinder clearance is held at 0.005–0.015 mm. Precision boring, honing and high-pressure die casting reduce pores in the body. Vacuum filling removes bubbles, and German FUCHS hydraulic oil improves behavior across temperatures.
How do you keep batch-to-batch consistency?
Raw material spectral analysis, 0.01–0.015 mm CNC machining, 100% functional and latching checks, automatic cycle and 180° to 0° calibration, and laboratory verification of endurance, damping and low-temperature performance.
What is a cam action door closer and when should I choose it?
It uses a cam mechanism instead of the common rack-and-pinion drive. Some designs lower opening effort and give smoother door movement, which suits commercial, high-traffic and accessibility doors. CE status depends on the model, so confirm it with our team.
