Luggage is our best assistant when traveling and is a must-have for almost every family trip. So are you curious about how such a seemingly simple suitcase is made?
As a global luggage supplier, it is my great honor to share with you the luggage production process. We can divide the manufacturing process into the following eight steps: designing and manufacturing molds, material selection and preparation, printing patterns, blown film molding, drilling and trimming, lining sewing, accessory assembly, quality inspection and packaging. steps. Every step embodies the hard work of the craftsmen and the exquisite technology. Let us explore the story behind the luggage together.
1. Design and manufacture molds
Product design is the first critical step in the luggage manufacturing process. First, the design team will conduct a preliminary design based on user needs, market trends and the latest design concepts, comprehensively considering the shape, size, pattern and function of the suitcase. In order to ensure the quality and practicality of the final product, the design team will communicate with the customer multiple times and repeatedly modify and test the design plan until the best effect is achieved. During the design process, the design team usually uses CAD software to complete the design of the mold to ensure accuracy in size and proportion.
Once the design is finalized, the mold manufacturing department starts manufacturing molds based on the design drawings. These molds will be used in subsequent manufacturing processes, and their quality directly affects the appearance and performance of the final product. ಆದ್ದರಿಂದ, mold manufacturing usually uses high-hardness steel as raw materials to ensure the durability and accuracy of the mold. In addition, the surface of the mold also needs special treatment, such as mirror polishing, to ensure that the surface of the product is smooth and beautiful after molding.
2. Material selection and preparation
The outer shell of the suitcase is usually made of high-strength, lightweight and durable thermoplastics such as ABS+PC and EVA as raw materials. These materials not only have good mechanical properties, but also have excellent resistance to impact, abrasion and chemical corrosion, making them ideal for the production of luggage.
In addition to traditional plastic materials, Zhongdi also has a special patented material CAPPEE. CAPPE is a new synthetic material made of silicone, ಎಬಿಎಸ್, PC and other materials. It combines the advantages of multiple materials, such as better toughness, impact resistance and wear resistance, allowing the suitcase to remain lightweight while still being lightweight. , with higher durability and reliability. The factory will select appropriate materials for production based on product positioning and market demand.
3. Printing pattern
In the luggage manufacturing process, printing patterns is one of the key steps to give the luggage personalization and appeal. Especially for children’s luggage, the clarity of the pattern and color is crucial.
The process of printing graphics typically uses screen printing or digital printing technology. Screen printing is a traditional printing method that uses a special screen template to imprint ink onto the outer shell of the luggage. This method is suitable for mass production and can achieve high-quality printing effects on a variety of materials. Digital printing technology is a more advanced printing method that uses inkjet printing technology to spray patterns directly on the outer shell of the luggage. Digital printing offers a high degree of flexibility and precision, making it easy to achieve complex patterns and color gradients, making it ideal for personalized luggage.
During the printing process, the factory will strictly control the printing process and quality to ensure the clarity of the pattern and the brightness of the color. At the same time, the factory will also design creative and interesting patterns based on children’s characteristics and preferences to meet children’s aesthetic needs.
4. Blown film molding
After the outer shell pattern of the suitcase is printed, the next step is to shape it. First, the shell of the printed number is placed in the machine, and the plastic material is heated to a molten state to make it fluid and plastic. It is then blown into pre-designed molds, where it cools to form a suitcase shell with a specific shape and structure. This step requires strict control of parameters such as temperature, pressure and speed to ensure the quality and appearance of the product.
5. Drilling and trimming
The formed suitcase shell requires subsequent processing such as drilling and trimming. First, through a preset program, the automatic machine will accurately punch holes in the shell. These holes will be used to install accessories such as wheels, pull rods, and handles. After the drilling is completed, the automatic edge trimmer cuts off the excess part of the shell.
During the entire punching and trimming process, the factory will strictly control the machine’s operating accuracy and speed to ensure that each suitcase shell reaches high quality standards. At the same time, the finished products will be strictly inspected to ensure that each hole position is accurate and the surface of the shell is smooth and flawless.
6. Lining sewing
Luggage linings are usually made from materials that are soft, hard-wearing, and easy to clean. During the sewing process, workers need to precisely cut and sew according to the size and structure of the suitcase to ensure a tight fit and good fixation of the lining to the outer shell. Through the installation of linings, the internal structure of the suitcase has been further improved and optimized.
7. Accessories assembly
Accessory assembly is the final stage of luggage manufacturing. Workers install accessories such as wheels, pull rods, and handles onto the luggage and make necessary adjustments and tests to ensure the stability and functionality of the product. The wheels need to be installed ensuring they are accurately aligned with the holes in the bottom of the suitcase and securely fastened. The installation of the tie rod requires adjusting its height and angle to ensure coordination with the suitcase shell and user convenience. In addition, the suitcase lock needs to be installed and debugged to ensure its safety and reliability.
8. Quality inspection and packaging
Finally, after the luggage is manufactured, it will be subject to strict quality inspection by the quality inspection department. During the quality inspection process, staff will conduct comprehensive inspections and tests on each manufactured luggage, including testing of appearance, zippers, casters, handles and other structures and functions. For non-conforming products found during the quality inspection process, staff will record and analyze the reasons in order to continuously optimize the production process. These unqualified products will be returned to the production process for repair or scrapping.
Only products that meet quality standards can enter the packaging process. According to customer needs, the factory can provide customized inner packaging for products. The outer packaging is uniformly made of thickened, compression-resistant, and shock-resistant cartons to protect the suitcases from damage during transportation and storage.
Through strict quality inspection and careful packaging, the luggage manufacturing process is completed successfully. These measures not only ensure product quality and safety, but also increase customer satisfaction and trust.
In short, the manufacturing process of luggage is a complex and delicate process that requires close cooperation and strict control of all links. Only in this way can we produce high-quality, high-performance luggage products that are loved by consumers.
