The first step is design. Design work must be carried out before production to determine the shape, size and structure of the chair. Excellent design should not only take aesthetics into account, but also functionality and comfort, ensuring that the chair is both durable and ergonomic. Designers will use CAD software for design and simulation to ensure the stability and load-bearing capacity of the chair.

The second step is to select the materials. The materials of plastic chairs are usually lightweight and durable plastics such as polypropylene or polyethylene. Choosing the right materials can ensure the strength and durability of the chair. Manufacturers usually purchase high-quality raw materials from reputable suppliers and conduct strict inspections on the raw materials.

The third step is to manufacture moulds. Plastic injection molding technology is required for the production of plastic chairs. Manufacturing molds is a crucial step in production. The precision and quality of the moulds will directly affect the quality of the final product. The manufacturing of moulds requires skilled craftsmen and high-precision equipment. Usually, manufacturers will entrust professional mould manufacturing companies to design and manufacture moulds.

The fourth step is injection molding. During the production process, plastic particles are first placed in an injection molding machine and heated to melt into a liquid state. Then, the molten plastic is injected into the mold through high-pressure injection to fill the entire space of the mould. After a certain period of cooling, the mold is opened and the plastic chair is formed. This process requires multiple adjustments and inspections to ensure the quality of each product.

The fifth step is the subsequent processing and assembly. After the production of plastic chairs is completed, subsequent processing and assembly work is still required, such as removing excess materials, grinding, spraying, and assembly. These processes can enhance the appearance and quality of the chair and ensure the perfection of the product.

The last step is quality inspection. After production is completed, quality inspection is an indispensable link. Through inspection, it can be confirmed whether the product meets the requirements. The inspector will examine the appearance, size, structure, load-bearing capacity and other aspects of the chair to ensure the perfection of the product.

 

 

 

To ensure the quality of plastic modern chair mould, we have a strict quality inspection procedure to guarantee that the quality of each link meets the standards.

Raw material inspection

Visual inspection: Check the surface of raw materials such as steel for cracks, sand holes, pores and other defects. The surface should be smooth without obvious scratches, oxide scale, etc.

Hardness testing: Use a hardness tester to test the hardness of raw materials to ensure that their hardness meets the design requirements.

2. Surface roughness detection

Three-coordinate measuring machine and PH10 probe: This is a common precision measurement device that can precisely measure the surface roughness of moulds.

Image processing software: Take high-definition photos of the mould surface and input them into the image processing software. The software can directly read the tiny details of the mold surface and calculate the surface roughness data.

3. Brightness detection

Spectrometer: It can precisely measure the smoothness of the mould surface. By comparing the standard spectral data, the smoothness of the mould surface can be obtained.

Take photos for observation: Take photos of the mould surface and enlarge them for observation to check if there are any obvious defects such as air holes and scratches.

4. Surface morphology detection

Scanning electron microscope (SEM) : It can observe the microstructure of the mould surface. It is necessary to separate the micro-samples on the mould surface and take high-definition photos of them through a scanning electron microscope.

Laser triangulation (LTT) : By using a laser measuring instrument, the shape and size of the mould surface can be measured with relatively high precision.

5. Dimension and fit dimension inspection

Basic dimension inspection: Check whether the basic dimensions of the mould meet the design requirements.

Fit dimension inspection: Check the fit dimensions between each component of the mould to ensure they can be assembled correctly.

6. Dynamic balance and static balance tests

For components operating at high speed, dynamic and static balance tests need to be conducted to ensure their stability during high-speed operation.

7. Strength and high-temperature tests

For components with high strength requirements, impact resistance tests, strength tests and high-temperature tests need to be conducted to ensure their performance under different conditions.

8. Inspection of vulnerable parts and spare parts

Inspect the vulnerable parts and spare parts of the mould to ensure they can be replaced in a timely manner during the production process, avoiding production interruption caused by the damage of vulnerable parts.

9. Trial assembly inspection

After the mould processing is completed, a trial assembly inspection is carried out to verify whether the fit dimensions and spatial surfaces of each component of the mold meet the design requirements.

10. Inspection of the appearance quality of products

Conduct an appearance quality inspection on the plastic chairs produced by the trial mold to ensure that their surfaces are smooth, free of obvious defects, and meet the design requirements.

 

 

Plastic modern chair mould alignment refers to the connection and alignment of the two halves of the mould during the mould design and manufacturing process to ensure the precision and quality of the product during the injection molding process. This process is extremely important because the contact of the mould will directly affect the forming effect and appearance of the final product.

First of all, when conducting the alignment, it is necessary to ensure that the two parts of the mould are completely in contact without any offset or gap. Only in this way can it be ensured that the product will not deform or have burrs during the injection molding process, thereby guaranteeing the quality and appearance of the product.

Secondly, when colliding, it is also necessary to check whether the surface of the mould is flat and whether there are any scratches or unevenness. If there are problems on the surface of the mold, it is very likely to cause the product surface to be rough or have flaws, affecting the appearance and quality of the product.

In addition, it is also necessary to pay attention to whether the gap and compression amount between the two parts of the mould are appropriate. If the gap is too large or the compression is insufficient, it is very likely to cause defects or residues in the product during the injection molding process, which will affect the use and sales of the product.

During the collision process, it is also necessary to pay attention to whether the cooling system of the mould is unobstructed and effective to ensure that the product can cool down quickly after injection molding, reduce the production cycle and improve production efficiency.
