Organic Hot Water Curing Vacuum Sealing Technology Infiltration Machine

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 manufacturing.

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 extended.
5. Castings are electroplated and impregnated before painting to extend the life of the parts and improve the surface treatment quality.
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.
performance
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 monomers
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.
