how we ensure the stability of our door closer

We take a series of strict testing steps on the door closers during mass production for your orders.

Vacuum Testing

We use a vacuum extractor to remove air from the door closer, then immerse it in water. If we see bubbles, it means there are defects. This helps us find and fix problems early, reducing the risk of oil leaks in the final products.

High Temperature Bakeout Testing

After filling oil and painting the door closer, we bake it at 65 degrees for one 1.5 hours to check for cracks, deformation, or oil leaks. This ensures we remove any defective products and maintain stable quality.

Life Cycle Testing

We randomly test 2-3 door closers from each batch by opening and closing them up to 300,000 times. Then we check for oil leaks, shifting, or abnormal noise during this testing operation, so as to ensure stable quality for each production batch.

Hydraulic Fluid Low Temperature Testing

We take 4-5 samples of anti-freezing hydraulic oil from each batch and freeze them for 72 hours. We then check if the oil remains fluid to ensure our products work properly in extremely cold areas.

Salt Spray Testing

We randomly test 2-3 door closers from each batch by placing them in a salt spray machine for 48 hours. We then check for paint loss or rust to ensure the durability of the paint treatment.

Spring Fatigue Testing

We randomly select 5-6 springs from each batch and test them in a compression fatigue machine for 48 hours. We check for wear and deformation, record the data, and strictly control its quality.

Our Product Advantages

What makes our products stand out is because we pay more attention to the product details than other suppliers do.
