We (UPLIFTEC) are a China Height Adjustable Desk manufacturer and in this blog post we invite you to explore our height Adjustable Desk manufacturing process behind the scenes. We'll share how our height-adjustable desk went from sheet metal to a height adjustable desk frame.
Height Adjustable Desk Frame Purchase Raw Materials - Cold Rolled Steel
Cold-rolled steel is the primary material for height adjustable desk frames. As can be seen from the picture, the electric height adjustable desk frame is mainly composed of five components: Foot, Lifting leg, Side bracket, Crossbeam, and Connecting beam. These five components are all made of cold-rolled steel. Our cold-rolled steel is all purchased from Baosteel Co., Ltd. Baosteel Co., Ltd. is the largest and most profitable steel supplier in China. We choose Baosteel as our steel supplier. Suppliers ensure product quality and supply chain stability in terms of raw materials.
The five components of the height-adjustable desk frame in the picture use cold-rolled steel of different thicknesses according to different forces and structures, including 1.5mm/2mm/3mm, etc., as follows:
1. Foot is 3.0mm cold rolled steel
2. Lifting leg is 2.0mm and 1.5mm cold rolled steel
3. Side bracket is 2.0mm cold rolled steel
4. Crossbeam is 1.5mm cold rolled steel
5. Connecting beam is 1.5mm cold rolled steel
Foot, Side bracket, is made of cold-rolled steel plate, as shown in the figure below:
Lifting leg, Crossbeam, and Connecting beam are made of cold-rolled steel pipes, as shown in the figure below:
For height-adjustable desk manufacturers, desks must be durable and last a decade or more. The height-adjustable desk uses cold-rolled steel as the main raw material because the cold-rolled steel plate has high strength and hardness, which allows it to withstand greater loads and pressures, thus ensuring the stability and durability of the electric height-adjustable desk.
As a China height-adjustable desk manufacturer, every link in producing height-adjustable desks undergoes strict quality control and is responsible for an order and the customer. Each batch of arriving raw materials needs to be randomly inspected, and professional quality inspectors will conduct quality acceptance of the steel. Strength testing: The strength and toughness of the steel will be evaluated through testing methods such as tensile testing and impact testing. Hardness Testing: Hardness testing is used to measure the hardness of steel to evaluate its ability to withstand compression. Thickness and deformation detection: Detect the thickness and deformation of steel to ensure that it meets product requirements.
Height Adjustable Desk Manufacturing Process - Laser Cutting
The first step in the manufacturing process of a height-adjustable desk is: laser cutting. The laser cutting machine cuts cold-rolled steel sheets or cold-rolled steel tubes to the dimensions of the different components of the height-adjustable desk. Laser cutting machines use high-power-density laser beams to irradiate workpieces to quickly melt, vaporize or ablate the materials to achieve cutting. Laser cutting machines can complete cutting tasks in a very short time, which significantly helps improve production efficiency.
Height Adjustable Desk Manufacturing Process - Grooving
Lifting leg in the height-adjustable desk frame. After the lifting leg is laser cut, the second step is slotting, which is used to make slots on the column legs to facilitate the installation of parts or connection of other parts. This is also a very common metal. Processing technology. The middle tube and the inner tube in a three stage height-adjustable desk need to be grooved. In a two stage height-adjustable column desk, only the inner tube needs to be grooved.
Except for the upright legs, no other components of the height-adjustable desk frame need to be slotted.
Height Adjustable Desk Manufacturing Process - Robot Welding
After the lifting leg completes the grooving step, welding begins. Lifting leg has several places that need to be welded. For example, the motor box needs to be welded on the outer tube of the column leg. The middle tube and inner tube need to be welded to the bottom plate. The column leg of a single motor needs to be welded to the beam bracket, etc. We use robot welding for welding. Robot welding is a highly automated welding technology that is widely used in industrial production. Its core advantage is to increase welding speed and efficiency. Robotic welding has good accuracy and stability, and can control the welding error within a small range, thus providing the welding quality and accuracy of the height-Adjustable Standing Desk frame. Height-adjustable table manufacturers pay great attention to the welding quality, because the higher the quality of the lifting leg welding, the more stable and smooth it will be during the lifting process.
In addition to the Standing Desk Lifting leg, there is another component Foot that also needs to be welded. As you can see from the picture below, there are many solder joints on the Foot, but these solder joints are all at the bottom of the Foot. When the Electric Standing Desk stand is installed You can't see these solder joints when you get it up.
The component Crossbeam has also undergone a welding process, as can be seen from the picture below :
Height Adjustable Desk Manufacturing Process - Bending
The side bracket and foot of the height-adjustable desk stand are bent through a bending process. The side bracket and foot are placed on the bending machine, and the metal is bent and formed by applying force through the bending lever. The side bracket starts out as a flat sheet metal piece and is bent into an L shape by a bending machine. The Foot is bent into a V shape by a bending machine. In addition to L-shape and V-shape, the bending machine can also turn flat sheet metal parts into U-shape or groove shape, etc. Bending (bending) is one of the most important and widely used techniques in the manufacture of electric height-adjustable desks.
Height Adjustable Desk Manufacturing Process - Polish
All the height-adjustable desk sheet metal parts in our factory are manually polished. Polishing is a very time-consuming and laborious process. There are nearly 10 people in the polishing department, all of whom are very experienced masters. Grinding and polishing the surface of the height-adjustable desk frame can remove rough traces on the surface and obtain a smooth surface. This is a very important step, which will determine the subsequent spraying adhesion of the sheet metal and the smoothness of the surface.
All five components of the height-adjustable desk frame need to be polished, and because manual polishing is more time-consuming, not only us, but other height-adjustable desk factories in China also have more employees in the polishing department.
Height Adjustable Desk Manufacturing Process - Spray
Spraying is the last step in sheet metal processing. The surface treatment of all height-adjustable desks is powder spraying. The particle size of powder coating is relatively small and the coating density is high, so the coating formed by powder spraying is relatively tight. Good corrosion resistance. The coating formed by powder spraying has a high gloss and can achieve a mirror effect. This is a perfect surface treatment for height-adjustable desks. In China, 90% of height-adjustable desk factories use powder coating. Very few customers ask for chrome plating, zinc plating, etc. This method is either too costly or not very stable.
So powder coating has become the first choice for height-adjustable standing desk manufacturers. The colors are black/white/gray. Other colors can also be customized according to customer requirements, because we are a height-adjustable desk manufacturer and have enough flexibility to meet customer needs.
Height Adjustable Desk Manufacturing Process - Assemble
After all the components of the height-adjustable desk are sprayed, they will be 100% inspected. Those that pass the inspection will enter the next step, which is assembly. The main thing is the assembly of the Lifting leg, which requires assembling the screw, motor, lifting column and other components to form a complete Lifting leg.
Height Adjustable Desk Manufacturing Process - Test
All assembled Lifting legs are 100% tested, mainly to test whether the current and voltage of the Lifting legs are stable, whether there are any abnormalities in the sound during the lifting process, etc. As a height-adjustable desk factory, it is very important to control the quality of every link in the production process, so as to ensure the quality of the finished product, and to ensure that the final product can meet the needs of use and bring comfort to users.
Height Adjustable Desk Manufacturing Process - Package
It`s time to reach the last step of manufacturing the height-adjustable desk - packaging. Each set of packaged height-Adjustable Sit Stand Desk will be checked again for weight. If the weight difference is large, you need to unpack and check whether there is anything missing. The purpose of this is to check whether there are missing accessories. Although it is the last step, you cannot be careless. Strict quality inspection is required for every link to ensure that all parts meet the requirements and quality standards.
