800ton Pressure Rubber Vulcanizing Machine And Hot Press Molding
Machine For Rubber Fender Manufacturing
Rubber Fender Vulcanizing Molding Press
I. Introduction
A rubber fender vulcanizing molding press is a crucial piece of
equipment in the manufacturing process of rubber fenders. Rubber
fenders play a vital role in the maritime and docking industries as
they act as shock absorbers, protecting ships and docks from damage
during berthing and mooring operations.
II. Working Principle
- Heating Mechanism
- The press is equipped with a heating system, usually through
electric heating elements, steam, or thermo - oil. The heat is
transferred to the platens (the large, flat surfaces of the press).
The platens are made of high - quality steel with excellent heat -
conducting properties. The temperature is carefully controlled to
reach the vulcanization temperature range of the rubber. For
example, most rubber fender vulcanization requires a temperature
between 140 - 160°C.
- Pressurization Process
- A hydraulic or mechanical system is used to apply pressure. The
hydraulic system consists of a hydraulic pump, cylinders, valves,
and hoses. The pressure forces the rubber material, which is placed
in a mold cavity, to conform to the shape of the mold and ensures
that the rubber molecules are in close contact. This is essential
for the vulcanization reaction to occur uniformly throughout the
rubber mass. The pressure can range from a few tons to several
hundred tons depending on the size and type of the rubber fender
being produced.
- Vulcanization Reaction
- During the vulcanization process, the rubber molecules react with
sulfur or other vulcanizing agents under the combined action of
heat and pressure. This cross - linking reaction transforms the
rubber from a soft and pliable material with relatively poor
mechanical properties into a tough and durable product. The cross -
links formed between the rubber chains give the rubber fender its
characteristic strength, elasticity, and resistance to abrasion and
environmental degradation.
III. Structure and Components
- Platen Assembly
- The platens are the main heating and pressing surfaces. They are
designed to provide even heat distribution and parallel alignment
to ensure uniform pressure on the mold. The surface of the platens
is usually precision - machined to have a high - quality finish,
which helps in the transfer of heat and pressure and also in the
production of smooth - surfaced rubber fenders.
- Hydraulic System
- As mentioned earlier, the hydraulic system is a key component. The
hydraulic pump supplies the necessary pressure to the cylinders.
The cylinders are connected to the movable platen (usually the
upper platen) and are responsible for the opening and closing of
the press and the application of pressure during the vulcanization
process. The hydraulic valves control the flow of hydraulic fluid
to regulate the speed and force of the platen movement and pressure
application.
- Mold System
- The mold is designed according to the specific shape and dimensions
of the rubber fender. It is usually made of high - strength steel
and is precisely machined to ensure the accurate formation of the
fender. The mold has channels and vents to allow for the escape of
air and any volatile substances generated during the vulcanization
process. This is crucial to prevent the formation of air bubbles or
voids in the rubber fender, which could affect its performance.
- Control System
- The control system of the press is becoming increasingly
sophisticated. It typically uses a Programmable Logic Controller
(PLC) to manage the various operations such as temperature control,
pressure regulation, and time - based functions. The operator can
set the desired vulcanization temperature, pressure, and time
through a touch - screen interface. The control system also
monitors the actual operating parameters and provides alarms and
safety shutdowns in case of any abnormal conditions such as over -
temperature, over - pressure, or equipment malfunction.
IV. Applications
- Maritime Industry
- Rubber fender vulcanizing molding presses are used to produce a
wide range of rubber fenders for ships and docks. These fenders are
installed on the sides of docks and on the hulls of ships to absorb
the impact energy when a ship berths. Different types of rubber
fenders, such as cylindrical fenders, arch fenders, and cell - type
fenders, can be produced using these presses to meet the specific
requirements of different docking situations and ship sizes.
- Industrial Facilities
- In addition to maritime applications, they are also used in
industrial settings where shock absorption and protection of
structures are needed. For example, in some factories where heavy
equipment or vehicles are moved around, custom - made rubber
fenders or bumpers can be produced using these presses to prevent
damage to the equipment and the building structures.
V. Advantages
- Quality Control
- The precise control of temperature, pressure, and time during the
vulcanization process ensures consistent product quality. The
rubber fenders produced have reliable mechanical and physical
properties, which is crucial for their long - term performance in
harsh marine environments.
- Efficiency
- Modern vulcanizing molding presses are designed for high -
productivity manufacturing. They can complete the vulcanization
process in a relatively short time, depending on the size and
complexity of the fender. The automated control systems also reduce
the need for extensive manual labor, increasing overall production
efficiency.
- Versatility
- These presses can be adjusted to produce different types and sizes
of rubber fenders. By changing the mold, a wide variety of shapes
and configurations can be achieved, allowing manufacturers to meet
the diverse needs of the market.
