The characteristic of small film blowing machine products is the need for continuous production, and the power is relatively high, so low power consumption, high reliability, and low noise are the preferred indicators for customers.

The working characteristic of a small film blowing machine is to maintain continuous high temperature operation for a long time, and electrical components are prone to aging, which will damage the insulation performance. If the electrical device of the product is unqualified, the equipment operator will lose the last layer of protection, and the consequences will be very serious. So products with unqualified electrical devices pose serious safety hazards.

The quality supervision department explained the main reasons for some small film blowing machine products being unqualified: firstly, some companies have insufficient understanding and implementation of the safety and performance requirements in the standards, and the hired electricians and workers do not understand the national electrical safety standards. The company leaders lack sufficient understanding of the serious consequences caused by unqualified electrical systems. Secondly, some companies have not installed qualified protective connection circuits and overcurrent protection devices in their products in order to reduce costs

The characteristic of small film blowing machine products is the need for continuous production, and the power is relatively high, so low power consumption, high reliability, and low noise are the preferred indicators for customers. When choosing this type of product, we offer three suggestions:

1. It is necessary to consider choosing a well-known equipment brand, and pay more attention to the key component brands of configuration, such as hydraulic pumps, hydraulic valves, wave pressure motors, motors, etc. The quality and after-sales service of brand products can be guaranteed

2. Understanding the quality management level of enterprises, for enterprises that have passed ISO9000 quality management system certification and European CE safety certification, the safety and technical performance of their products must be trustworthy,

3. Search for relevant technical documents, such as certificates of conformity, user manuals, packing lists, and software operation manuals. Generally, small film blowing machine companies that value these technical documents also place relatively high importance on product quality.
