The technological process of manufacturing molds and rods directly depends on the characteristics of the molding mixtures. The properties of the castings, the accuracy of their geometric dimensions and roughness also depend on the quality of the equipment. The most common are mixtures obtained on the basis of various types of binders that harden in air without the need for heating (HCS). These can be synthetic resins or liquid glass. <\/p>\n\n

HTS casting technology in foundry production.<\/h5>\n\n

The main goal of CTS in foundry production is to create optimal conditions for molding and casting metal products.<\/p>\n\n

During the production of molds and cores, the composition of the XTS molding mixture is selected in such a way as to ensure high quality castings, allow for the regeneration of the molding mass, reduce the amount of toxic emissions and the cost of materials.<\/p>\n\n

The casting method is based on the properties of the sand-resin mixture to harden under the influence of a catalyst. The composition of the core mixture of the phenol-formaldehyde base HTS allows you to produce complex castings of high quality. This ensures good surface cleanliness and maintains the accuracy of geometric dimensions. <\/p>\n\n

Such quality indicators cannot be ensured during casting in sand-clay molds. Since in this case the requirements of low humidity, sufficient level of gas permeability, and dimensional accuracy are not met. To obtain the required humidity when using a sand-clay mixture, prolonged drying is required, which significantly increases energy consumption and increases the duration of the technological cycle. <\/p>\n\n

HTS mixtures may contain binders that provide strength to molds and molding blocks. They may also include components that protect the metal from oxidation at high temperatures, which is very important for preventing defects on the surface of the casting. <\/p>\n\n

Advantages and disadvantages of using CTS in foundry production<\/h5>\n\n

The advantages of making molding materials from cold-hardening mixtures, the composition of which is selected depending on the casting material, include:<\/p>\n\n
