How to Choose PU Pneumatic Hose?

There are many varieties of PU pneumatic hoses. Generally, the production material is PU with stable quality, high pressure resistance, weather resistance, wear resistance, tortuous resistance. The tube is smooth and flexible, bright color, high elasticity, bending resistance and small bending radius. Next, Orientflex will introduce what should be considered when choosing.

Whether the wall thickness of the fused billet of the pneumatic tube is uniform, whether a higher blowing pressure is needed, whether the blowing is uniform, whether the surface of the pneumatic tube is bright, whether the demoulding is simple and whether the strength can meet the requirements, etc.

Comparison of the performance of blow – moulded pneumatic hose. Blow molding pneumatic tube in the thermo – elastic state, its density is smaller than the cooling after the finalization of the density, resulting in shortening. For general size is not strict pneumatic tube, forming shortening has little effect. But for the specified size of the pneumatic tube, such as some hoses used in precision machines, shorten large has a considerable impact. The larger the volume of blow molding, the more significant the influence.

The advantages of extrusion blowing plastic molding pneumatic hose are the less investment of equipment, simple equipment structure, simple mold, high forming of pneumatic tube, and temperature control is more uniform, can form a variety of specifications of pneumatic tube. The disadvantage is that the wall thickness uniformity of the pneumatic tube is poor.

The advantages of injection blowing molding pneumatic tube is that plastic pneumatic tube products are of good quality, precise dimensions, no joints, uniform wall thickness, multi-mode molding production, high degree of automation, very suitable for small specifications of large quantities of high efficiency production. The disadvantage is that the equipment and molding mold investment is large, the operation of production is to use technical workers.

The above is Orientflex, a professional hose manufacturer, for you to introduce related knowledge about PU pneumatic hose. Our company mainly produces pneumatic tubes, PVC hoses, industrial hoses, hydraulic hoses, silicone hoses, etc. You can check the company’s website for more information.
