Catalogue of machines for testing and producing rubber:
In rubber processing, the table press is called a flat
vulcanization machine. Its main parameters include nominal tonnage,
pressure plate size, working stroke, and plunger diameter, which
determine the area, height, or thickness of the molded product that
the machine can produce, as well as the achievable molding
pressure. According to their structural characteristics, molds can
be divided into three types: overflow, non overflow, and semi
overflow, with the latter being the most commonly used. The process
includes feeding, mold closing, exhaust, curing, demolding, and
mold cleaning. If the product has embedded parts that need to be
sealed during molding, the embedded parts should be placed before
feeding. The main controlled process conditions are pressure, mold
temperature, and molding time. The molding method is also an
extremely important molding method in the rubber industry. The
rubber material is cut or punched into simple shapes, added to a
heating mold, and vulcanized while forming. The product is also
demolded while still hot. Many rubber model products, such as
gaskets and shock absorbers (such as rubber rings and plates), are
produced using this method.
The Rubber Hydraulic Vulcanizing Machine is controlled by a
high-performance oil pressure system for smooth lifting and
lowering after startup; High precision compression clearance,
high-strength wear-resistant guide pillar, strong load-bearing
capacity; The pressurization system itself has an automatic
pressure compensation function, which can preset the time and
pressure for primary and secondary pressurization; Using Taiwanese
electric heating plate material, it is resistant to high
temperature, corrosion, fast heat transfer, and does not deform;
The surface is covered with a stainless steel layer, which is
clean, free of dirt, and easy to clean.
Precautions for using the Rubber Hydraulic Vulcanizing Machine:
1. The operating pressure should not exceed the rated pressure.
2. The small size of the mold cannot be smaller than the diameter
of the plunger. The mold should be placed in the middle of the hot
plate; The working fluid pressure should be adjusted according to
the size of the mold and the vulcanization time.
3. Keep electrical components and instruments clean, and ensure
that each instrument is not struck or knocked. The host and control
box should have reliable grounding.
4. If a malfunction is found, the machine should be immediately
shut down for maintenance. Cut off the main power supply when
stopping use.
5. All components of the machine should be kept clean, and the
column shaft and guide frame should be lubricated regularly to
maintain good lubrication.
