Introducing the cutting method of stretch film

1. Sawing is divided into manual sawing and sawing machine cutting. The main tool for manual sawing is a handmade hacksaw, which has two types: movable and fixed, both composed of a saw bow and a saw blade.
2. Sawing machine cutting is equipped with high-speed hacksaw blades on the sawing machine, which can cut various metal films and plastic films below DN200mm. Portable electric sawing machines are often used on construction sites, and their cutting membrane diameter is 550mm.
3. Stretch membrane pressure test includes two aspects: membrane product pressure test and membrane system pressure test. Pressure test of membrane products is to check the compressive strength and tightness of the membrane product itself, usually based on the multiple of the nominal pressure of the corresponding membrane product or the specified value corresponding to the membrane channel level and membrane diameter as the test face pressure value.
4. The pressure test of the stretch film channel system mainly checks the compressive strength and tightness of various different interfaces after various membrane products are formed by a system with a variety of different connection methods, and the test pressure value is generally taken by the system design pressure, that is, the multiple of the system working pressure.
There are generally two ways to cut stretch film. Manual and machine cutting, no matter which form of cutting, the main purpose is to ensure that the quality can be guaranteed throughout the cutting process, and I hope you can pay more attention in the future.
