The Male Half Of The Hinge Set
Our company, Kunshan Qunju Metal Products Co., Ltd., produces this garage door hinge pin. The model number is QJ-GD1002. This part is also called a pivot hinge. It is the male half. Hinges have two halves. The male half has the pin. The female half has the hole. The pin goes into the hole. Then the two halves can rotate freely. Our garage door hinge pinss has very high machining precision. The pin diameter tolerance is plus or minus 0.05 millimeters. We use steel to make this hinge pin. The surface has zinc plating. Our company has 60 employees. Five of them are R&D staff. When they designed this product, they paid special attention to the chamfer. The head of the pin has a 45-degree chamfer. This helps the installer align the pin with the female hole. No hard hammering is needed. A gentle push slides it in. This small detail improves installation speed. Many customers have praised this.
Environmentally Friendly Plating Process
Our factory follows local environmental rules. We use a cyanide-free zinc plating process. Waste water is treated before discharge. We have an environmental inspection report from the local authorities. If you need this report, we can provide it. Many European customers ask suppliers for environmental certificates. We have them. You can feel safe working with us. How do we control quality? We have a dedicated quality control department. We use a projector to check the pin profile. The projector enlarges the pin 20 times. We can see if the chamfer is correct. We also use thread gauges. But this garage door hinge pin has no threads. So we mainly check the diameter and length. For each batch, we sample 10 pieces. If one piece is bad, we re-check the whole batch.
