Double Worktables Hydraulic polystyrene foam cutting machine is the most popular cutting off machine all over the world. PS foam cutting machine is mainly used to cut the vacuum forming products (one time dishes)as well as packing, decoration, and EPE deep processing products. Our polystyrene cutting machine adopts the Mitsubishi brand PLC mechanical and electronic integration. Owing to the PS foam cutting machine’s features of easily changing mould, counting accurately, and cutting off quickly, it is widely used in many fields.
For flexible foam molding, dispensing machines are used to vary the output of chemicals or the component ratios during the pour. This allows the production of molded foams with dual hardness. Molded foam articles with solid surface skin are made from liquid chemicals in a single step, using carbon dioxide as the sole blowing agent. Automotive cushions are made by molding flexible foam behind a pre-shaped fabric cover. This process reduces the number of steps in the manufacture of car seats. In addition to monitoring the production process, the final product is inspected and tested for various physical and mechanical properties. An important property of foam rubber is called the indentation load deflection, which measures the spring tension or load-bearing quality of the material. The deflection is determined by the amount of weight needed to compress a circle of foam 50 sq in x 4 in (127 sq cm x 10.16 cm) thick by 25%. Most seat cushion foam has a rating of 35, which means it takes 35 lb (15.9 kg) of pressure to compress the circle of foam 1 in (2.54 cm).
EPE foam cloth called pearl cotton which is made of polyethene (LDPE), after heating and plasticizing, foaming, cooling, and extrusion process. The characteristics of the material are: Sound insulation, heat insulation, moisture, shock, non-toxic, no smell, plasticity is good etc. It can make 0.5-25mm sheet material. Haiyuan EPE foam machine and pe foam sheet extrusion line can use EPE foam cloth to make all kinds of packing materials and packing materials after the overlying, film-forming. Our EPE foam machine is widely used in electronics, electrical components, handicrafts, daily necessities, glass, ceramics, household appliances, furniture, fruit and other products packaging.
Most foams consist of the following chemicals: 50% polyol, 40% polyisocyanates, and 10% water and other chemicals. Polyisocyanates and polyols are liquid polymers that, when combined with water, produce an exothermic (heat generating) reaction forming the polyurethane. The two polyisocyanates most commonly used are diphenylethane diisocyanate (MDI) and toluene diisocyanate (TDI). Both are derived from readily available petrochemicals and are manufactured by well-established chemical processes. Though MDI is chemically more complex than TDI, this complexity allows its composition to be tailored for each specific application. MDI is generally used in rigid foams, whereas TDI is typically used for flexible foam applications. Blends of MDI and TDI are also used.
