Product technology

The manufacturing process of spring door closers is a complex and delicate process, which mainly includes the following key steps:

1. Select materials that meet quality requirements, including spring steel, metal shells, connecting rods and other necessary parts. These materials will undergo strict screening and pretreatment to ensure that their physical and chemical properties meet the manufacturing needs of door closers.

2. The spring is the core component of the door closer, and its manufacturing process is particularly critical. Through precise cutting, bending and heat treatment processes, the spring steel is processed into a spring shape that meets the design requirements. During this process, we strictly control the tension, elasticity and durability of the spring to ensure stable performance of the door closer.

3. Assemble the manufactured spring with other parts to form the mechanical part of the door closer. During the assembly process, ensure that the fit between the various components is precise and stable to achieve the normal function of the door closer.

4. Make a metal casing and install the assembled mechanism part into the casing. The manufacturing of the casing needs to ensure a certain degree of strength and durability, as well as good appearance and protective properties.

5. After completing the assembly of the door closer, we will conduct debugging and testing. This includes adjusting the closing speed, strength and other parameters of the door closer to ensure that its performance meets the design requirements. At the same time, conduct multiple switch tests to check whether the door closer operates smoothly and without noise, and can meet the automatic closing requirements of the door.

6. Finally, perform quality inspection on the door closer to ensure that it complies with relevant standards and specifications. The inspected door closers will be packaged for transportation and storage.

In the actual production process, we usually formulate detailed manufacturing processes and quality control standards based on our own technical level and market demand to ensure the best quality and performance of the door closers.

FAQ

Q1. If we don't have any drawings, what should we do?
A1: To enable us to duplicate or offer you superior solutions, kindly submit your sample to our manufacturer. Send us photos or drafts that include the following dimensions: thickness, length, height, and width. If you place an order, a CAD or 3D file will be created for you.
Q2: What sets you apart from the others?
A2: 1) Our Superb Assistance If we get comprehensive information within business hours, we will submit the quotation within 48 hours. 2) Our rapid turnaround for manufacturing We guarantee 3–4 weeks for production for regular orders. As a factory, we are able to guarantee the delivery date as specified in the official contract.
Q3: Is it feasible to find out how well my products are selling without physically visiting your business?
A3: We will provide a thorough production schedule along with weekly reports that include images or videos demonstrating the status of the machining.
Q4: Is it possible to receive samples or a trial order for a few items only?
A4: Because the product is personalized and needs to be made, we will charge for the sample. However, if the sample is not more expensive than the bulk order, we will reimburse the sample cost.
