  • How to do the daily maintenance of EPS CNC cutting machine?

    EPS foam CNC cutting machine, which is mainly used for cutting EPS foam material, can cut soft and hard eps foam and plastic into rectangular, strip and other different shapes. High efficiency, accurate size and high precision. Compared with ordinary eps foam cutting machine, EPS CNC foam cutting machine is combined with PLC control, equipped with CAD drawing software, and also supports U input. Data can be uploaded and imported directly, compatibility is stronger, operation is simpler, automation is higher, software typesetting, and no skill and technology requirements are required. The pr...

  • What is EPS

    Expandable polystyrene is a kind of polystyrene product with foaming agent. Abbreviated code “EPS”. The appearance is colorless and transparent bead particles. Common foaming agents are low boiling hydrocarbons (such as petroleum ether, butane, pentane, etc.), which are prepared by one-step reaction of styrene monomer in autoclave; It can also be polymerized and added with foaming agent to gradually penetrate into the polymer body, which is called two-step method. After one-step foaming, the foam cell of the product is uniform and fine, the product has good elasticity, but the...

  • Merry Christmas

    Christmas Eve is the night before Christmas, Christmas is December 25, Christmas Eve is the night of December 24.

In Germany, it is said that Santa Claus will dress up as a holy child and put nuts and apples in children’s shoes. He travel...

  • What is the shrinkage in EPS mold manufacturing

    1. Shrinkage deformation will occur after EPS molding and demoulding In general, the shrinkage of EPS is 0% – 0.3%. The specific shrinkage rate is related to the characteristics of each material, process conditions (especially demoulding temperature), product density and thickness. In some cases, such as high demoulding temperature and thick product, EPS products not only do not shrink, but expand. Therefore, the shrinkage deformation of EPS and general molding process characteristics should be considered in the mold manufacturing process. The size of the mold should be appropriately...

  • What’s the application of EPS block molding machine?

    EPS Block Molding Machine is to produce EPS blocks. According to different cooling way, EPS block molding machine can be catogorized to expanded polystyrene vacuum block molding machine and expanded polystyrene air cooling block molding machine. Air cooling block molding machine is suitable for small capacity request and low density blocks production, it’s economic machine. Vacuum block molding machine can produce high density blocks, works fast cycle, with low water content in blocks. Machine all complete with control box, vacuum system, weighing system etc. Type has standard type, transla...
