With more than 30 years customers` actual operation
and technology improvement, 1500mm two/three/five layers fully automatic
Stretch Film Machine is mature and cost-effective, some whole production line
adopt melt metering pump technology and high precision pressure sensor system,
which can stably and effective to control the pressure. It will highly improves
film horizontal and vertical`s tension strength and anti-puncture resistance
and make the film meeting the high requirement for machine packing film. The
cooling roller adopts big diameter design and special double-decker runner,
greatly improving the cooling effect of high-speed production to guarantee good
uniformity of cooling roll surface temperature. The film produced by this
machine has good shrinking memory function and self-sticky, which can be widely
used in wrapping of palletized goods. It`s good substitute for hot shrinking
packing film during transportation.

melt metering pump is more and more important in extrusion process, especially
in high-end products industries, such as high quality sheets, pipes, BOPP,
optical cable.
Installing the melt metering pump in the cast
stretch film unit, which can keep the production constantly and efficiency. The
pump can improve the product quality, stable the production and decrease the
energy consume.
The housing is made of chromium-nickel alloy or
nickel-base alloy, titanium alloy. The gear is made of quenching chromium
steel, other metal materials are also applicable. Bearing is made of graphite
NIAG, zirconium oxide or quench tool steel.
Advantages:
FAST AND STABLE FLOW SUPPLY
Eliminated the extruder`s pulsation wave. Improve
the product quality, decrease the defective rate, and decrease the waste, which
can save 2% material and 25% of the unit power consumption.
STABLE AND EFFICIENCY PRESSURE CONTROL
The melt pump can provide a stable pressure, which
short the discharge time obviously and make the production effectively.
INCREASE THE EXTRUDER OUTPUT AND THE MACHINE LIFE
It has been found that after install the melt pump,
the max pressure wave value is the pressure after pump. Which can make the
inner pressure of the extruder decrease, the melt shear strength decrease, the
temperature curve gently, and restrain the temperature rising. Also the melt
pump can avoid the damage to the extruder from the high pressure.

The person in charge of the project of highway water transport engineering construction as mentioned in the "production system" refers to the project manager, deputy manager, and project chief of the construction contract section of the highway water transport project. Where a construction company establishes a position as a safety director, it also includes a safety director.
The "Production System" stipulates that during the construction of a highway water transport project, the person in charge of the project must take turns in production at the construction site. The person in charge of the project may not, in principle, undertake the safety production management of two or more construction contract sections at the same time. If he or she does need to hold concurrent duties, he shall obtain the written consent of the project construction unit. The project manager is the first person responsible for the safe production management of the construction contract section of the highway water transport project and is responsible for implementing the overall leadership responsibility for the production system with shifts.
The project management department of highway water transport engineering construction contract section shall establish a system of rotation and shift production on the construction site according to the construction characteristics of the project, clarify the requirements for work content, duties and authority, personnel arrangement, and assessment rewards and penalties, and formulate a monthly production plan with shifts, and strictly Implementation. For subcontracted contracts with professional (or labor) subcontracts, the subcontracting units shall formulate monthly production plans with shifts and report them to the project manager of the contractor for record. For the project of general construction contracting, the project segment (division or site) implementation unit shall formulate a monthly production plan with shifts and report it to the general contracting project manager for record.
The competent transportation authorities at all levels and their safety oversight agencies shall strengthen the supervision of the implementation of the production and shifting production system at the construction site of the construction enterprise project leader. Those responsible for projects that have not implemented the production system with shifts are recorded as personal bad credits, and they are not allowed to perform deferred assessments of their safety production evaluation certificates. For a construction company that has not implemented a production system with poor production or is ineffective, it should be ordered to make corrections and report criticisms. At the same time, it should be recorded as a company's bad credit. If a quality and safety accident occurs, it should be punished with administrative penalties in accordance with the law and be held responsible for legal liabilities.
“Supervisory Management System†clarified that the hidden dangers of major accidents in safe production of highway water transport projects (hereinafter referred to as “major hidden troublesâ€) refer to the high degree of harm in the construction process of highway water transport projects, and the difficulty of rectification is relatively large, which may lead to group deaths and injuries. Hidden dangers of safety accidents or safety accidents that cause major economic losses and adverse social impacts.
The major supervision and management of highway water transport projects will be conducted in accordance with the principle of territorial management. The competent department of transportation under the State Council is responsible for supervising and guiding the major hidden dangers in all regions. The competent department of transportation at the provincial level is responsible for supervising the major hidden dangers reported by the competent transportation department at the next level, or the major hidden dangers that should be directly supervised by the competent authorities; The competent department of transportation administration is responsible for supervising the major hidden dangers in the region according to its responsibilities. Where there are major hidden troubles in trans-regional or inter-departmental engineering projects, the project jurisdictions shall supervise and supervise them; for the serious problems that may lead to serious accidents or major adverse social impacts, they may be reported to the provinces, autonomous regions and municipalities directly under the central government. The competent department of transportation or the government production safety committee at the same level shall supervise and supervise the work. Major hazards should be handled by other departments, transferred to other departments and registered for future reference.
The major hidden trouble investigation and treatment of highway water transport construction projects implements the working mechanism of “owner organization, supervision and verification, and construction managementâ€. Participating parties should ensure that the process of hidden investigations, public announcements, and management sales numbers are closed and the files are complete.
The "Supervisory System" requires that all levels of transportation authorities should establish a database of major hazard investigation and management, and gradually implement remote monitoring of major hazards on the construction site. At the same time, the supervision of major hidden dangers will be incorporated into the important content of the assessment of safe production work, and rewards will be given to regions and enterprises that have carried out major hidden trouble management work. Regions and enterprises that have failed to carry out the inspection and supervision of major hidden dangers will be subject to public criticism, legal person interviews, and administrative penalties, depending on the situation. If serious consequences are caused, they shall be relied on in accordance with the law.
The Ministry of Transport issued two new regulations
Recently, the Ministry of Transport printed and issued the "Project Construction Personnel for Construction of Highway Water Transportation Engineering Enterprises (Provisional) Production System (Interim)" (hereinafter referred to as "Production System") and "List of Supervision System for Major Safety Hazards of Highway Water Transportation Engineering (Interim)" (Hereinafter referred to as "supervision system").
