Ningbo Fangli Technology Co., Ltd. is a mechanical equipment manufacturer with nearly 30 years’ experiences of plastic
pipe extrusion equipment, new environmental protection and new materials
equipment. Since its establishment Fangli has been developed based on user’s
demands. Through continuous improvement, independent R&D on the core
technology and digestion & absorption of advanced technology and other
means, we have developed PVC pipe extrusion line, PP-R pipe extrusion line, PE
water supply / gas pipe extrusion line, which was recommended by the Chinese
Ministry of Construction to replace imported products. We have gained the title
of “First-class Brand in Zhejiang Province”.
To optimize productivity and operational
cost, HDPE pipe extrusion line manufacturers ensure that all parameters are
identified, monitored, and controlled.
Some of the variables are hinged on the
equipment and the prevailing operating conditions and this affects HDPE pipe
production line cost.
These variables range from the quality of
materials and die used to physical conditions such as temperatures and
pressures.
Common problems associated with HDPE
extrusion pipe productions are put into a few categories.
However, before you get to know these
problems, partnering with a reliable HDPE pipe extrusion line manufacturer
guarantees you the best quality HDPE pipe extrusion.
Common problems relating to the manufacture
of HDPE extrusion pipes are put into the following categories:
1. Aesthetic Flaws
These are sink marks, tiny holes, drag
marks, pits, black specs, and die lines that are found in the HDPE extrusion
pipe product.
2. Variation in size
Size variance is another common problem
associated with HDPE extrusion pipe products. These can be intermittent or
contiguous variance in size.
3. Dimensional variation
These are irregularities in the length and
width of the extrusion pipes. In preventing these problems in the extrusion
processing line, the first call is to checkup the components of the
manufacturing process beginning with the equipment.
The cause could be from the screw design,
irregularities in the process temperature, or improperly laid die itself.
Other variables to be examined when the
extruded products don’t meet the required finished product standards are:
· Melt pressure
· The velocity of the line
· The motor load
· Cooling power
· Heating power
Again, some preventative steps can be taken
before the start of the production process. These are:
1.
There should be proper calibrations of instruments used to monitor
changes in pressure, temperature, and amperage at least twice in a year.
This is important to ensure the readings
are precise and do not drift in the course of the production.
2. A steady condition of resins should be
consistently maintained.
The resins should be stored in a dry and
clean place without being subjected to abrupt variations in temperature.
If the resin is too dry, it may not melt
properly and hence the resin cannot be processed.
Some HDPE pipe extrusion line manufacturers
carry out routine resin analysis to evaluate its quality such as melting index,
shear rate, tensile strength, etc.
Changes from one batch of resin mid-way in
the production process can alter the product. This should be avoided.
The machine should be monitored closely to
maintain an efficient extrusion process and get rid of any quality issues.
Conclusion
In any HDPE manufacturing firm, the goal is
to have a productive and competitive advantage over others.
Problems in the production process can
hamper the realization of this dream.
Hence, the need to partner with a reliable
HDPE pipe extrusion line manufacturers for professional advice and first-grade
quality products.
