My opinion of carton production

1 The design determines the final effect of the product

The design of carton products is particularly important, otherwise it is difficult to meet customer requirements, may return, causing major losses to the enterprise.

I think that when the marketing department receives an order, it should pass all customer information to the process design department. Including the decorative requirements of the layout, size, box structure, content and weight, stacking layers and other related content. After the design department is designed, it can be passed to the manufacturing department to complete the product realization.

1) Calculate the maximum stacking load Ps that the lowermost carton can withstand

That is, Ps=(Nmax-1)G, where Nmax is the maximum number of stacking layers and G is the contents and box weight.

2) Select the appropriate safety factor K

According to the requirements of SN/T0262-93 export shipping packaging corrugated cardboard inspection procedures, when the storage period is less than 30 days, K = 1.6: the storage period is 30 - 100 days, K = 1.65; when the storage period is more than 100 days, K = 2.

Of course, for the sake of safety, the safety factor usually takes 3 or more. However, the safety factor has been too large, the various indices of raw materials are relatively high, and the price of paper will rise significantly, resulting in increased costs and unfavorable market development. In addition, if the safety factor is selected too large, there will be excess quality, too small coefficients, and quality problems such as collapse of the box. Therefore, according to the actual requirements of customers, select the appropriate safety factor.

3) Calculate the maximum compressive strength value to be achieved according to the safety factor P

That is P=K.Ps

4) According to Kelicutt formula, choose the right paper combination

That is, Px·F=P (calculated)

So Px=P/F, where F is a constant related to the carton perimeter and corrugated type, which is obtained by looking up the table. Px is the integrated crush strength value of corrugated board, Px = (R1+R2+Rm1C)/15.2
If the ring pressure index and gram weight of any one or two of R1, R2, and Rm1C are known, the ring pressure index and gram weight of the third material can be obtained to achieve the purpose of reasonable matching of paper. 2 Do process control is the guarantee of product realization

Whether the products designed by the technology and technology department can be well implemented or not, and the strict implementation of the standards in each process is crucial. Therefore, the squad leader of each process is required to supervise and supervise the product quality of this process in time, which is the guarantee of the final quality of the product.

In addition, quality supervisors should conduct inspections from time to time to correct and deal with the phenomenon of violations of the technology in a timely manner so as to ensure the strict implementation of the process. 3 Pay attention to customers and do a good job of after-sales service In the process of accepting products, if customers find that the products they received cannot meet his expectations, then it will produce some complaints and dissatisfaction. This requires the organization to establish an information management system suitable for the company's internal information, clear the flow of information, make full use of information to achieve customer satisfaction.
