HPM high -pressure foaming principle
  Both Polyol and Isocyanate are stored separately in two tank, and used two rotary axial metering pumps to take material to mixing head, two components injection to a small mixing room at high pressure and flow rate when mixing head started in the hydraulic control, and collide with each other instantly, pass moving transformation that reached to mixing and flow to mold control, after pouring output time that mixing head piston rod forward, all material are pushed to mixing chamber and mixing chamber is cleaned by piston rod, don't left any material. Component passed beside of piston rod return to material tank. If it don't inject in a long time , low-pressure recalculation switchover unit but two-control component into low recalculation.
 Because of equipment' exact calculation, has a small loss and needn't clean and it will be good at environment-protect and reduce the material costs. In the all areas that is to be more and more widely used.

An airless bottle is a type of packaging for cosmetics, skincare products, or other liquids that uses a non-pressurized vacuum for dispensing the product. This design helps to keep the product fresh by preventing air exposure, which can degrade the product over time. Large Lip Gloss Tube.Airless Pump Bottles.The bottle has a diaphragm that rises to evacuate the product. When the bottle is filled, the material stored inside the bottle is preserved and maintains its integrity until used up.Airless Pump Container. Airless bottle technology helps to extend the shelf life of the skincare product, lotion, or serum, making them more effective for a longer period.Big head Lipstick Tube
