The selection techniques of die-cut foam

When choosing to die-cut foam, you must make a good comparison. Don't compare prices blindly. You must learn to identify the "brand-name products" in the operators' mouths. The most expensive is not necessarily the best. Next, let's take a look at the techniques of choosing die-cut foam. Here are some answers.

Know and understand die-cut foam.

The die-cutting production process is widely used in the molding process of cartons, cartons, paper bags, book covers, plastics, leather products, and other packaging and decoration products. A considerable part of die-cutting products also includes indentation production processes. Therefore, people habitually refer to the die-cutting and creasing process as the die-cutting process for short. Due to the different structures and characteristics of various products, the die-cutting production methods used should also be different, so die-cutting machines also have a variety of structures and forms. There are many types of die-cut foam and die-cut foams of different materials and shapes have different functions. If you choose the wrong die-cut foam, not only will it not be a good cushion, but it may also become a safety hazard, which may cause danger at any time.

Eight elements of choosing die-cut foam.

Any type of die-cut foam, to ensure a long-term useful seal in harsh operating environments, must have the following eight important characteristics: first, airtightness, regarding the medium of the sealing system, die-cut foam No leakage occurs within a certain period at the recommended temperature and pressure. Second, compressibility. The contact surface of die-cut foam and flange should be able to fit well after the connecting bolts are tightened to ensure sealing. Third, creep resistance. Under the influence of pressure load and operating temperature, the die-cut foam should have good creep resistance, otherwise, it will cause the loss of bolt torque and reduce the surface stress of die-cut foam, and then the hard gas system Leak.

Fourth, resistance to chemical corrosion. The selected die-cut foam should not be corroded by the chemical medium and should not contaminate the medium. Fifth, resilience. Even when the system is stable, the two connected flanges will have a small displacement due to the influence of temperature and pressure. The elastic function of die-cut foam should compensate for this displacement to ensure the sealing of the system. Sixth, anti-adhesion, the die-cut foam should be easily removed from the flange after use, without adhesion. The seventh, non-corrosive, die-cut foam should be non-corrosive on the flange surface to be connected. Eighth, temperature resistance. The die-cut foam selected should be used normally at the lowest and highest temperature of the system.
