The production process of plastic storage boxes is a complex and delicate process involving multiple key steps and professional techniques. In this article, LEBO will introduce you to the production process of our plastic storage boxes and how their colors are customized.
The Production Process of Plastic Storage Boxes
Raw material selection and preparation
Raw material selection: The main raw materials of plastic storage boxes include thermoplastics such as polypropylene (PP) and polyethylene (PE). These materials are lightweight, wear-resistant, corrosion-resistant, and easy to process, making them very suitable for making storage boxes.
Raw material coloring and proportioning: According to product color and design requirements, plastic raw materials are mixed with toner, engine oil, and other additives in a certain proportion, and stirred evenly through a mixer to make colored pigments. This step ensures the final color and design of the plastic storage boxes.
Mold design and manufacturing
Mold design: Mold is a key tool in the production process of plastic storage boxes. Its design needs to take into account factors such as the size, structure, and wall thickness of the storage containers. Mold design is usually carried out using professional CAD/CAM software to ensure the accuracy and efficiency of the mold.
Mold manufacturing: Use precision machining equipment (such as CNC machine tools) to manufacture molds according to design drawings. After the mold is manufactured, strict inspection and mold testing are required to ensure that it meets production requirements.
Injection molding
Injection molding machine preparation: Put the prepared plastic raw materials into the hopper of the injection molding machine, and set the temperature, pressure and other parameters of the injection molding machine.
Injection molding: An injection molding machine injects molten plastic into a mold, which cools to form the preliminary shape of the storage box. Parameters such as temperature, pressure and time need to be strictly controlled during the injection molding process to ensure product quality and dimensional accuracy.
Demolding and post-processing: After injection molding is completed, open the mold to take out the product, and perform post-processing work such as deburring and trimming. These steps help improve the appearance quality and performance of plastic storage boxes.
Surface treatment
In order to improve the appearance quality and durability of plastic storage boxes, surface treatment is usually required. Common surface treatment methods include anti-static treatment, UV light uniform treatment, etc. These treatments can reduce the static load of the material itself and prevent dust absorption. At the same time, make the plastic storage boxes color more vivid and durable.
Assembly and testing
Assembly: Assemble the various components of the plastic storage boxes to form a complete storage box product. During the assembly process, attention should be paid to the matching and tightness of the components to ensure the stability and durability of the product.
Testing: Perform quality inspection on the assembled storage box, including appearance inspection, size measurement, functional testing, etc. Only products that meet quality standards can enter the next process.
Packaging and delivery
Packaging: Qualified plastic storage boxes are packaged to protect the products from damage during transportation and storage. Packaging materials usually include cartons, plastic bags, etc.
Delivery: After packaging, the plastic storage boxes will be shipped to the sales point or warehouse for sale. Before delivery, a final inspection and inventory are required to ensure that the quantity and quality of the products meet the requirements.
In summary, the production process of plastic storage boxes is a complex and delicate process involving multiple links such as raw material selection, mold design and manufacturing, injection molding, surface treatment, assembly and testing, packaging and delivery. Each link needs to be strictly controlled and checked to ensure that the quality and performance of the product meet the requirements.
How to Customize the Color of Plastic Storage Boxes?
Identify your needs
First, it is necessary to clearly understand the specific requirements of the bulk plastic storage boxes color required by the customer, including color codes (such as PANTONE color numbers), color effects (such as matte, and glossy), and whether there are special visual effects requirements (such as gradient, metallic luster, etc.).
Sample confirmation
Design plan: Based on customer needs, Lebo designers will draw a design plan for the storage box, which includes the choice of color and presentation. The design plan needs to be communicated and confirmed with the customer many times to ensure that the color selection meets the customer’s expectations.
Color samples: After the design plan is initially approved, Lebo will make color samples or provide design renderings so that customers can more intuitively understand the actual effect of the color.
Raw material preparation
Raw material selection: According to the color determined in the design plan, select suitable plastic raw materials and add corresponding color powder or masterbatch for coloring. The selection of raw materials needs to consider factors such as color stability, weather resistance, and wear resistance.
Raw material coloring: Mix the color powder or masterbatch with the plastic raw material in a certain proportion to ensure that the coloring effect is consistent and meets the plastic storage boxes design you need.
Injection molding
Mold preparation: Ensure that the injection mold is clean and undamaged, and adjust the mold parameters such as temperature and pressure according to the design requirements.
Injection molding: The colored plastic raw material is injected into the mold, and the initial shape of the plastic storage boxes is formed after cooling. Parameters such as temperature, pressure and time need to be strictly controlled during the injection molding process to ensure the color and quality of the product.
Color inspection and adjustment
Preliminary inspection: Perform preliminary color inspection on the injection molded storage box to check whether the color is uniform and consistent, and compare it with the design requirements.
Adjustment and optimization: If the color is deviated or does not meet the requirements, it is necessary to adjust the raw material ratio, injection molding parameters, etc. in time, and adjust them multiple times until the color effect meets the customer’s satisfaction.
Subsequent processing and packaging
Deburring and trimming: Perform post-processing such as deburring and trimming on the injection molded storage box to improve the appearance quality of the product.
Color protection: As needed, the plastic storage boxes can be surface treated (such as UV light uniform treatment) to enhance the durability and gloss of the color.
Packaging and delivery: After all subsequent processing is completed, the bulk plastic storage boxes are packaged and prepared for delivery. During the packaging process, it is necessary to protect the color of the product from damage.
Customer confirmation and feedback
Sample confirmation: Before mass production, a small number of samples are usually made for customer confirmation. Customers need to conduct a comprehensive inspection of the color, quality, etc. of the samples and give feedback.
Mass production: After the customer confirms that the sample is correct, Lebo will carry out mass production. The color quality still needs to be strictly controlled during the production process to ensure that the color of each batch of products is consistent and meets the design requirements.
Through the above procedures, it can be ensured that the customized plastic storage boxes meet the customer’s expectations in color and maintain a high level of quality to meet the customer’s needs.
