Organic Hot Water Curing Vacuum Sealing Technology Infiltration
Organic hot water curing vacuum infiltration sealing technology:
From inorganic infiltration to organic infiltration technology, it
is the reform and innovation of our infiltration technology.
Compared with inorganic infiltration, the technology of organic
infiltration is much more difficult. However, the product after
organic impregnation is relatively much better. So in the future,
we will focus on organic vacuum infiltration sealing technology.
Organic Thermal Curing Infiltration Sealing Technology - Solve the
sealing problems of cracks, micropores and blisters in metal
castings and powder metallurgy. In the manufacturing process of die
castings and powder metallurgy parts, due to crystal shrinkage and
other reasons, a large number of micropores, blisters, cracks are
inevitably formed, and microporous leakage brings hidden dangers to
the use of machinery and equipment, even for use without pressure
requirements. It may also cause internal corrosion due to the
penetration of cleaning agents, acid liquids, etc. into the parts
due to electroplating, painting and other surface treatments,
shortening the service life of the parts, and forming bubbles or
irregularities on the surface painting, electroplating, etc. due to
the presence of micropores.
With the continuous development of micro-hole sealing technology,
it will become possible to manufacture perfect castings and
finished metallurgical materials. The use of T90c vacuum
infiltration hot water curing microporous sealant solves the
technical problems that have long plagued the foundry industry. Low
equipment investment, simple operation, fast and high reliability
(more than 98% success rate of one impregnation). The design of the
parts can be thinned, and the high-pressure parts can be subjected
to bursting, so that the proportion of rework and recasting that
has been required in the past is reduced to zero. Compared with
other processes, the production cost is greatly reduced. In the
domestic market, especially in the motor vehicle manufacturing
industry, the demand for the T90c is rapidly increasing, mainly for
regulators, carburetor, automatic transmission housings, automobile
cylinder blocks, cylinder heads, crankcases, compressor housings,
and the like.
With the development and application of this technology, it is
being applied more and more widely in various fields of industrial
Vacuum pressure infiltration equipment and its infiltration agent.
The infiltration device can effectively seal the leakage of the
casting due to micropore defects, and is mainly used for the
cylinder block, cylinder head and various pump casings of engines
of various mechanical manufacturing industries such as airplanes,
ships, high-speed rails, automobiles, motorcycles, and the like. ,
bath, valve body and other pressure castings.
Advantages of organic infiltration agents
1. Simple operation and high efficiency. An infiltration process
can be completed in 20 minutes, and the pass rate of the workpiece
is over 98%.
2. 100% reaction curing does not shrink, the cured product is tough
and resistant to aging, and is resistant to chemical media. It can
seal 1.5um ultra-fine pores.
3. Easy to clean without affecting the surface accuracy of the
workpiece. It does not corrode metals and is harmless to operators
and the environment.
4. After the powder metallurgy is infiltrated after sintering, the
processing speed can be increased and the tool life can be greatly
5. Castings are electroplated and impregnated before painting to
extend the life of the parts and improve the surface treatment
6. Comparison with inorganic sealing salt and synthetic resin
Although the material cost of inorganic sealing acid salt and
synthetic resin is only a fraction of that of thermal curing
infiltration agent, the cost of scrap casting is comprehensively
compared. Can adjust consumption. Time savings due to greatly
improved efficiency. The heat curing infiltration process will
greatly reduce the cost.
a. Curing mechanism
The T90c impregnation liquid initiates polymerization of the
monomer by raising the temperature to form a thermosetting plastic,
thereby filling the pores.
b. Basic performance
Ingredients: T90c is mainly composed of a mixture of methacrylate
For the micro-hole sealing problems in the industries of powder
metallurgy and casting production, Hongshun Automation has set up
an infiltration center to manufacture infiltration equipment and
produce high-quality organic impregnating liquid T90c to meet the
domestic customers' solution to cracks in metal parts. The need for
microporous sealing problems such as micropores and blisters.
