PVC Suction Hose Profile Bending

PVC Suction Hose Profile bending

Plastic Hose | PVC Pore Reasoning and Causes of Profile Bending

   PVC straw pipe fittings in the production often appear bending or warping situation, why is this phenomenon? Let's take a look:

   The first reason for this situation is the shape of the mold, the tractor and the nose is not a straight line, it should be timely adjustment of stereotypes die, tractor position; the second reason is the machine head is not uniform, should be adjusted or The third reason is the uneven temperature, resulting in internal stress, should adjust the temperature; the fifth reason is to squeeze the mold; the third reason is the cooling The speed is too fast, so that poor profile cooling, should be appropriate to reduce the extrusion speed.

VC pipe required process conditions

        PVC straw pipe fittings used in many ways, and its production needs what kind of conditions? The following by Xiaobian to introduce you to:

        First, the PVC straw usually does not require drying, but its melting temperature needs 185 ~ 205C, the mold temperature needs 20 ~ 50C, the injection pressure can reach 1500bar pressure, 1000bar injection speed: In order to avoid material degradation, generally with a considerable Of the injection speed. In addition, for its runners and gates, all conventional gates can be used. If smaller parts are machined, it is advisable to use needle tip gates or submersible gates; for thicker parts, it is best to use fan-shaped gates. The minimum diameter of the needle tip or submersible gate shall be 1 mm; the thickness of the fan gate shall not be less than 1 mm. Plastic hose | pvc insulation hose, pvc insulation hose is a vacuum plastic film, used for all kinds of panel surface packaging, it is also known as decorative film, with film, used in building materials, packaging, Medicine and many other industries. Which accounted for the largest proportion of building materials industry, 60%, followed by the packaging industry, there are several other small-scale application of the industry.

   pvc steel hose according to the purpose is divided into: threading hose, drainage hose, ventilation hose, shower hose, wire tube.

   According to the material are divided into: stainless steel hose, metal hose, corrugated hose, rubber hose, plastic hose.
