Metal Banquet Chair Manufacturer

Description

The aluminium dining chair has been carefully designed and rigorously tested for various commercial spaces,
such as offices, restaurants, and hotels. Its stable structure and elegant appearance make it an ideal choice for
these environments.

For added sitting comfort, the chair also offers an optional cushion in a modern box style, which is
beautiful and adds a layer of comfort. Whether a short break or long work, the Delta aluminium
dining chair can bring you lasting comfort and support.

1. Raw material selection

First, select high-quality aluminium from suppliers. The selected aluminium must meet strict quality standards
and have excellent strength and durability. These aluminium materials are usually anodized to improve their
corrosion resistance and surface hardness.

According to the design requirements, workers use **laser cutting machines or CNC cutting equipment** to
accurately cut metal pipes. Laser cutting technology uses high-energy laser beams to melt or vaporize materials
to ensure smooth cuts without burrs, while CNC cutting equipment (CNC) uses computer programs to accurately
control the cutting path so that the size error of each component is controlled within the micron range

2. Machine Cutting

The aluminium is fed into a high-precision cutting machine and precisely cut using a computer-controlled
laser or water jet. During the cutting process, the machine operates according to the preset design drawings
to ensure that the size and shape of each component exactly meet the design requirements. The cut parts
will be inspected one by one to ensure there are no defects or dimensional deviations.

This high-precision cutting process not only improves production efficiency but also reduces material waste,
Ensuring that each component strictly meets the design standards in shape and size, providing a perfect fit
for subsequent welding and assembly, thereby ensuring the stability and structural strength of the finished
metal dining chair.

3. Frame processing and welding

After all the metal parts are ready, the welding process begins. This step determines the overall strength and
service life of the chair. To ensure the quality of welding, argon arc welding (TIG welding) or laser welding
technology is mainly used.

Using high-energy laser beams to perform local melting welding on metals, the heat-affected area is small,
which can effectively avoid material deformation or damage. It is suitable for thin-walled metal structures
with delicate welds, reducing the workload of subsequent grinding and improving production efficiency.

During the welding process, craftsmen strictly control the heat input to prevent metal deformation, uneven
welds or unstable structures caused by overheating. At the same time, each welding point will be tested
multiple times to ensure its firmness to support the long-term use of the metal dining chair.

Especially in the hollow part of the chair back, corners and weld intersections, these areas are difficult to fully
cover with automatic polishing equipment due to complex structures and small spaces. Therefore, craftsmen
must repeatedly polish by hand to ensure smooth edges without roughness or welding residues.

Rough polishing: Use an angle grinder with grinding wheels of different mesh sizes to first remove the
protruding parts of the weld and the uneven surface areas to make the overall surface smoother.

Fine polishing: Use a wool polishing wheel or soft polishing sheet to finely process minor flaws to further
improve the uniformity of the metal surface.

Mirror polishing: Finally, apply a special polishing paste and use a high-speed polishing process to make the
metal surface presents a mirror gloss, which not only increases the beauty but also improves corrosion
resistance and prevents oxidation or discoloration after long-term use.

4. Backrest pattern processing

The preheated aluminium is fed into the bending machine, where a precise hydraulic system applies uniform
pressure to bend the aluminium into a semicircular shape. During this process, the operator will constantly
adjust the pressure and bending angle to ensure that the curvature and shape meet the design requirements.

First, the craftsman pre-positions the backrest parts according to the design drawings and molds. Since the
backrest usually adopts a hollow design or an arc structure, it needs to be fixed with a precision fixture to
ensure that the angles and spacings of each part meet the standards to avoid tilting or uneven shapes.

After fixing, workers use spot welding technology to temporarily weld the key connection points of the
backrest shape to ensure the initial structural stability. At this time, technicians will conduct correction
inspections, using laser measuring instruments or special alignment tools to check whether the symmetry
and overall curvature of the backrest meet the standards, and make fine adjustments if there are deviations.

5. Chair back bending

After installing the backrest on the mould, the hydraulic system applies uniform pressure to bend the backrest
component into the desired shape. The operator will adjust the pressure and bending angle according to the
design requirements to ensure that the curvature and shape are fully ergonomically designed. During the
bending process, the operator will constantly monitor and adjust to ensure that every detail is accurate.

The metal is shaped using a tube bender and a press to ensure an accurate bending angle. After that, the
backrest is ground and polished to give it a smooth and beautiful surface. After completing these steps, all
backrest parts are stored in a designated area, waiting for further assembly.

6. Chair overall frame assembly

Next, the seat and legs are installed. Align the treated backrest with the seat and legs, and firmly connect the
parts using screws, rivets or welding. After ensuring that all connection points are stable, a final
quality check is carried out to confirm that the chair is structurally stable and comfortable. After the
final inspection, the finished product can be packaged and shipped to the point of sale or the customer.

Sand the edges of the seat and legs. Use a grinding wheel or sandpaper to sand all edges to make them
smooth and neat, without burrs and sharp corners, to ensure safety and appearance. Use sandpaper of
different grits gradually to achieve the best sanding effect. After sanding, align the seat and legs to ensure
the correct position. Use screws, rivets or welding to fix the seat to the legs firmly. Make sure all connection
points are firm and the chair structure is stable.

The frame of each chair is hand-welded to ensure quality and durability. This exquisite craftsmanship enables
the chair to withstand various pressures during use, providing excellent stability and reliability. Whether for
home use or commercial premises, these chairs can maintain their perfect condition for a long time, bringing
you lasting comfort and peace of mind.

Before painting or plating, we need to thoroughly clean and polish the surface of the chair. This is a key step
to ensure the final coating effect. First, mix a neutral detergent and warm water to make a cleaning solution.

Use a clean cloth or sponge to dip the cleaning solution in and gently wipe every part of the chair to remove
all dust, grease, and stains thoroughly. Then, rinse the chair with clean water to ensure no residual detergent.
Finally, wipe the chair with a dry cloth or let the chair air dry naturally.

If you need a bar stool, we can also make it for you. Whether it is for a home, bar, cafe or restaurant, our bar
stools can add a modern and unique style to your space. Each bar stool is not only beautifully designed
but also highly practical and comfortable, ensuring that you and your guests can enjoy the best experience.

Next, use fine sandpaper to lightly sand the surface of the chair. The sandpaper can be folded or used in a
sandpaper block to better control the sanding force. Sand each surface of the chair evenly, paying special
attention to the edges and corners to ensure that the entire surface is treated. This process will make the
surface smoother and help the paint or lacquer to adhere better. Once sanding is completed, use a clean
cloth or soft brush to clean up any dust and ensure that the surface of the chair is completely clean and
ready for the next painting or lacquer job.
