　　The international express delivery and freight industry has been booming in recent years, providing great convenience for overseas Chinese, international students and foreign trade merchants. However, while this industry is developing rapidly, it also hides some unknown unspoken rules.among freight forwarder china to usa It has given great spiritual support to entrepreneurs, and more entrepreneurs will contribute to this industry in the future. https://www.freeseaship.com/

　　This article will analyze these unspoken rules in depth to help everyone better understand and deal with them.

　　container shipping

　　1. Low price trap

　　The quotation issue is an important aspect of the international express freight forwarding industry. Many consumers are often attracted by some low quotations when choosing freight forwarding companies.

　　In order to attract consumers, some unscrupulous merchants will deliberately lower prices, or even use the banner of “free shipping”. However, in actual operations, these merchants often charge additional fees through various means, such as packaging fees, insurance fees, tariffs, etc., which results in consumers ultimately paying much more than expected.

　　Therefore, when choosing international express shipping services, consumers must carefully read the contract terms, understand all possible fees, and choose reputable merchants.

　　container shipping

　　2. Packaging issues

　　Some freight forwarding companies often use non-standard packaging methods to save costs or improve efficiency during the packaging process. This may not only cause damage to the goods during transportation, but also affect the customs clearance and delivery of the goods.

　　In addition, some companies deliberately increase the size of packages and fillers to increase shipping costs. Therefore, when choosing a shipping company, consumers should pay attention to its packaging method and attitude to ensure that the goods are properly packaged and protected.

　　international express

　　3. Transportation Issues

　　Lost items, customs clearance and delivery issues are also a major pain point in the international express logistics industry.

　　Due to the complexity of cross-border logistics, lost items often occur. Some freight forwarding companies often have a negative attitude when dealing with lost items, and even shirk responsibility. In addition, customs clearance is also a place where problems are prone to occur. Due to the lack of professional customs clearance knowledge and experience, some freight forwarding companies have caused the goods to be detained or returned during customs clearance. Delivery issues are mainly manifested in untimely delivery and inability to deliver to the door.

　　international express

　　4. After-sales service

　　After-sales service is a very important link in the international express freight forwarding industry. Some freight forwarding companies often lack timely and professional after-sales service during the service process. When consumers encounter problems or need consultation, customer service staff often cannot provide effective solutions or respond very slowly. This not only affects consumers’ shopping experience, but also weakens consumers’ trust in freight forwarding companies.

　　international express

　　In summary, when choosing a freight forwarding company, consumers should be vigilant and fully understand the company’s reputation, quotation, packaging method, customs clearance ability and after-sales service. At the same time, freight forwarding companies should also strengthen self-discipline and standardize business operations to improve service quality and customer satisfaction. Only in this way can the healthy development of the international express freight forwarding industry be promoted.

　　The mold steel material used in mold parts processing has high hardness, and the mold processing equipment is required to have thermal stability and high reliability.consequently plastic moulding parts I also got a lot of attention and wanted to join the ranks. https://www.dghrjmmj.com

　　For complex cavities and multifunctional composite molds, as the shape of the parts becomes more complicated, the design and manufacturing level of the mold must be improved. Multifunctional composite molds that form or assemble multiple grooves and multiple materials in a set of molds require a large amount of processing programming, high deep hole comprehensive cutting ability and high stability, which increases the difficulty of processing. The processing quality of mold parts includes processing accuracy and surface quality: processing accuracy is the degree of conformity between the three geometric parameters of the actual size, shape, and position of the surface of the part after processing and the ideal geometric parameters required by the drawing; the deviation value between the actual geometric parameters of the part and the ideal geometric parameters is called processing error.

　　Processing accuracy and processing error are both terms for evaluating the geometric parameters of the processing surface. Processing accuracy is measured by tolerance grade. The smaller the grade value, the higher the accuracy; processing error is expressed by numerical value. The larger the numerical value, the greater the error. High processing accuracy means small processing error, and vice versa; the actual parameters obtained by any processing method will not be absolutely accurate. From the function of the part, as long as the processing error is within the tolerance range required by the part drawing, it is considered that the processing accuracy is guaranteed.

　　The quality of a machine depends on the processing quality of the parts and the assembly quality of the machine. The processing quality of the parts includes two parts: processing accuracy and surface quality. Machining accuracy refers to the degree to which the actual geometric parameters (size, shape and position) of the parts after processing are consistent with the ideal geometric parameters. The difference between them is called processing error. The size of the processing error reflects the level of processing accuracy. The larger the error, the lower the processing accuracy, and the smaller the error, the higher the processing accuracy; the main aspects that affect processing accuracy: dimensional accuracy, the degree to which the actual size of the part after processing is consistent with the center of the tolerance zone of the part size.
