Polyurethane foam injection machines are divided into high-pressure polyurethane foam making machines and low-pressure polyurethane foam pouring machines. Different industries can use different types of foam injection machines to make different kinds of polyurethane foam products.
Features of polyurethane low pressure foaming machine:
1. The pouring head designed with patented technology adopts a rotary valve three-position cylinder, which controls the air flushing and liquid washing as the upper cylinder, controls the backflow as the middle cylinder, and controls the pouring as the lower cylinder. This special structure can ensure that the injection hole and the cleaning hole will never be blocked, and is equipped with a discharge regulator (throttle piece) for stepwise adjustment and a return valve for stepless adjustment, so that the entire pouring and mixing process is always synchronized. Consistent, thus ensuring product quality. 2 Using high-precision metering pump and frequency conversion to adjust the speed, the adjustment is accurate, the operation is stable, and the operation is convenient.

High strength and excellent dimensional stability: easy to process, because it does not absorb water, its dry and wet strength does not change. Determined by the properties of the material itself, the size basically does not change with humidity. At constant temperature, within the relative humidity of 0-100%, it can maintain excellent dimensional stability. It still maintains toughness and flexibility at -73 degrees and begins to shrink at 118 degrees; it begins to melt at 135 degrees. Therefore, the heating temperature should not exceed 79 degrees to avoid deformation, and ironing of home textile products is not recommended. Excellent: Fold-resistant, tolerates more than 20,000 repeated folds, and is durable.
