1. Seven hole plum tube Introduction:
Seven-hole plum tube is HDPE (high-density polyethylene) as raw material, extruded by an extrusion molding production, the single hole wall intersection, close melting of a cable sheath pipe, HDPE porous plum tube with waterproof, moisture, anti-aging, long life, good weather resistance characteristics. As the seven-hole plum pipe is a one-time forming of the integrated porous casing, so easy construction, increased the number of embedded holes, increased construction speed, greatly reducing the engineering unit of materials and construction costs. Products with waterproof, moisture, anti-aging, long life, good weather resistance characteristics. Plum tube features: the tube was plum-like, increased lighting, heat cycle to speed up, hot water heating speed.
Seven hole plum tube Uses:
Seven-hole plum tube is mainly used for communication cables, telecommunications cable network, long-distance communication lines and cable television broadcast transmission network. With both rigid and flexible, less laying process, construction convenience, safe and reliable, low cost and other advantages.
2. Pipe production line of the process
Vacuum Feeding → Drying system → Conical Single Screw Extruder → Extrusion pipe Mold → Calibrator → Water Cooling Tank → Ink Printing Machine → Haul-Off Machine → cutting machine → pipe stacking machine → finished product testing packaging.
Auxiliary machinery:
HDPE pipe Crusher, HDPE pipe Shredder.
3. Equipment Features:
**Conical single Screw Extruder with suitable L\D,specifically for HDPE material, properties to ensure uniform and efficient extrusion. Reliable temperature control system
**Mold: suitable for processing of the split head, both to ensure high-speed extrusion stability, but also to avoid the decomposition of non-crystalline plastic reaction, access to high-quality pipe. The internal heating control system, more efficient, more convenient extrusion; accurate tin bronze and phosphor bronze sizing sets can quickly set the tube cooling.
**Spray cooling water tank: rapid vacuum molding system can squeeze the material in a short time rapid cooling sizing, through the vacuum sizing the box automatic temperature control system, water level constant pressure device and vacuum automatic adjustment device, can greatly improve Pipe shape cooling effect and production speed, and to ensure production stability.
**The use of multi-track tractor, through the central motor to drive all the tracks to achieve a high degree of synchronization, and to ensure the roundness of the pipe, tractor track with high wear-resistant rubber material, traction smooth high speed, long service life.
**The use of high-speed, precision design of the cutting machine, cutting section formation, and with a strong suction device, the maintenance work to a minimum.
**The use of double furnace heating automatic flaring machine, vacuum sizing, both to ensure the quality of the flaring, but also improve the flaring efficiency.
***Auxiliary machinery:
HDPE pipe crusher.
HDPE pipe Shredder.
