Analysis of the process and key points of carton design (Part 2)

when it is determined that various design input conditions can meet the design, it is necessary to analyze, classify and sort out these conditions (transportation and storage, delivery time, circulation time, product characteristics/size, weight and special requirements), acceptance standards, box structure, pattern and color code, etc. First, determine whether the cartons required to be designed focus on transport cartons or torque selling cartons used to detect and correct all kinds of electric pneumatic screwdrivers, torque drivers and torque wrenches:

sales cartons belong to the category of commercial packaging, focus on the appearance of cartons, and consider the requirements of printing process when designing

transportation cartons belong to the industrial packaging category, and more need to consider the compression resistance and shock resistance of cartons. Due to its repeated use, it is also necessary to consider the efficiency of packing and the production efficiency of the factory

when it is determined that it is required to design transportation cartons or sales cartons, as well as the carton packaging between them; You can start designing cartons

a specific idea needs to be completed by the designer, which requires not only the structural designer to master the knowledge and information in time, but also the ability of spatial thinking. According to the data collected by the customer research, the carton type and size will be further determined. The selection of box type and size will be based on the following conditions:

the box type of the carton will be determined according to whether it is a sales carton or a transportation carton (some customers have specified the structure of the carton)

determine the size of the carton:

the characteristics of the contents (size, weight, center of gravity, arrangement and combination, etc.)

determine the inner size of the carton

determine the external dimension of the carton (especially when pallets or containers are used for loading)

determine the manufacturing size of the carton

after the size is determined, the compression resistance, stacking calculation and material allocation can be carried out. Calculate the compressive and stacking strength according to the calculation formula:

calculation formula of compressive strength: P = kg (3/h － 1) × 9.8

calculation of stacking strength: pi = kg (3/h-1)

calculate the edge compression strength and ring compression strength of the paper plate through reverse reasoning of the stacking strength of the compressive strength, and cooperate with GB to select the corrugated carton and version code through the size and the weight of the contents, and then check the bursting strength, edge compression strength, puncture strength, adhesion strength and other data of the carton type; Use Carey Carter formula to calculate the paperboard material. It should be noted that whether the carton box is perforated, the appropriate temperature of the circulation environment, the printing position, and the size of the printing and die-cutting pressure will all affect the result value, so it must be considered comprehensively in the calculation

when all conditions are met, you can use the drawing software to draw and proofing the carton structure. From the completion of proofing to the production of small samples, it is a link that involves the most personnel and the most cumbersome process; Therefore, it is required in this link:

try to communicate with the personnel of all relevant departments to prevent errors due to delayed process handover, reduced work efficiency or unclear handover

adopt scientific processes and standards to manage and follow them

the "work contact list" can be used for the contact between work, and the written documents can be used for the review between various processes and the confirmation of samples, so as to get more feedback of design data and opinions

by adopting the "one-to-one" method in which one customer and one designer are responsible, we can have a more comprehensive understanding of the potential requirements of customers, and can communicate well with relevant personnel in internal handover or review

when the designer hands over the design drawings to the proofer, it is necessary to carefully check the designed products. If conditions permit, designers should directly participate in proofing, so as to improve the designed products in time, especially in the aspect of detail improvement

because the strength of cartons is reduced due to the influence of production technology and other aspects in the actual production process, the performance detection of cartons is directly related to the material allocation and type of cartons. When dealing with this problem, on the one hand, we should refer to the previous data in the company's database, and on the other hand, we need to constantly collect the strength gap between the proofed products and the products produced by die cutting. Then determine whether the strength of the carton can meet the requirements through comprehensive consideration. In terms of process review, designers need to be able to understand the maximum production capacity of the company's internal equipment, so they should pay more attention to communicating with on-site staff at ordinary times. Designers should understand this knowledge as much as possible, otherwise a design that takes a lot of time may need to be redesigned because the equipment cannot be produced due to the improvement of the positive income. If the designer does not know much about the process knowledge, he can directly submit it to the technologist for review after the design is completed, because the performance of all aspects of carton testing needs to be considered in the process review, so let the technologist repeat this work more. If the process verification design meets the relevant requirements, it can be confirmed to the customer, and only after the customer approves it can it be molded and produced. If the requirements are not met, the process must be repeated and redesigned or modified

when mold making is completed, small samples are made, or mass production is carried out, and customers use it, both technologists and designers must track the products, and collect relevant production information and feedback from all aspects in a timely manner, and input various data into the company's database. It is a machine mainly used to test the fatigue performance of metals and their alloys under tensile, compressive or alternating tensile and compressive loads at room temperature. The data in the database can allow designers to consult these information at any time during the whole design process, so as to achieve a better and more customer-friendly design and create win-win opportunities with customers

the above just briefly discussed some basic problems in the process of structural design. It's really not easy to design a product that satisfies customers. Therefore, in the work, designers are not only required to constantly innovate, but also required to constantly adjust the process within the organization to adapt to the changing internal and external environment. As a more service-oriented work, it not only designs products for customers, but also requires designers to guide the entire carton packaging users. Because designers of carton enterprises must know more about carton packaging information than carton users, when users' requirements are not very reasonable, practical and economic, designers should strive to communicate with customers, recommend packaging methods that are practical for their products, and let customers change their inherent views on carton packaging, This may bring a larger market space to the development of carton design
