Some people say that sofa leg hardware accessories are very simple products, without any technical content, and do not require any sophisticated and difficult production processes. They are just a small "supporting role".

 

In fact, the role of sofa leg hardware accessories in sofas has always been indispensable part. People's focus on the quality of sofas has also shifted from the conspicuous main materials to the quality of hardware accessories.

 

Good-quality hardware accessories have a series of strict requirements in terms of materials, design, manufacturing and use. In addition to high quality and durability, the manufactured products also take into account the humanization of the use process, comfort and convenience in use, and matching with product styles.

 

 

Raw materials

The raw materials for sofa legs are alloys based on zinc and other elements. Low melting point, good fluidity, easy to weld and plastic processing, corrosion resistant in the atmosphere.

Features: good casting performance, precision parts with complex die-casting shapes and walls, smooth casting surface, good process performance;

Points to consider when selecting zinc alloy: mechanical properties, tensile strength;

Working environment conditions: temperature, humidity, media contacted by the workpiece and airtightness requirements;

Precision requirements: achievable accuracy and dimensional stability;

High cost performance: the cost of raw materials and the requirements for production equipment; 

 

Stamping

Before cutting, metal stamping requires proofing the sheet and measuring its size, thickness and mechanical properties. In general, ordinary sheet materials can be directly processed by punching machines, but some complex products also require multiple stages of processing such as sheet metal processing. During the sheet cutting process, steel shears, hydraulic cutting machines, wire cutting machines, plasma cutting machines and other equipment are required.

 

Bending and forming stage

Bending and forming is one of the core processes of metal stamping. There are many ways to bend, such as bending and forming, roll bending and forming. Bending is usually processed using a hydraulic roller punch or a plate bending machine.

 

When bending, metal stamping workers need to strictly control the bending angle, curvature and bending cracks to ensure good overall performance and quality.

 

Punching, shearing and bolting processing stages

In the punching, shearing and bolting processing stages of the metal stamping process, the processor needs to perform trimming, debarring, punching and surface processing before proceeding to the next step.

 

During the process, shearing machines, punching machines and sheet metal processing equipment are required to achieve functions such as punching, shearing and surface processing.

 

 

Welding and surface treatment stages of metal stamping

Metal stamping processing requires different processing operations according to different products during the welding and surface treatment stages. There are many welding methods, such as gas welding, argon arc welding, and MIG welding.

 

Surface treatment includes spraying, electroplating, polishing, oxidation and other methods to increase product corrosion resistance, increase hardness, prevent wear, improve smoothness, heat resistance and surface beauty.

 

Metal stamping processors need to choose appropriate processing methods according to actual conditions, and control factors such as welding strength and surface treatment quality to ensure the quality of the final product.

 

Finished product packaging

Packaging is the final link in the production of finished products. If there is a quality problem with the packaging, even if the product quality is good, customers will completely deny the product because of the bad impression of the packaging, so the closer it is to the last minute, the more attention it pays.

 

Pay special attention to the fact that the bagged products are not short of weight; the packaging bags are waterproof and drop-proof; the cartons are thickened and not easy to break; and they can withstand long-distance transportation and bad weather.
