V.M. Gruzman On the Fate of Frozen Molds
The main obstacles on the way to the wide adoption of frozen molds in the industry have been analyzed. Technological and organizational methods of overcoming those obstacles are shown. Examples of practical implementation of the recommended methods are given. Special attention is paid to the organic unity of frozen cores and V-process of molding. Lower cost of frozen cores as compared to cold-hardening ones has been substantiated. The necessity of using frozen cores for V-process molds is substantiated.

Obrezkov V.V. et al. The Advantages of Water Glass Preparation from Dry Concentrate A new high-speed method of making water glass (WG) from dry concentrate (DC) has a number of advantages over the conventional methods. It is versatile, allows to rapidly prepare batches of binder of any volume with any required modulus and density, no steam autoclaves being required. WG produced from DC features new properties: high strengthening speed, higher heat resistance, better shakeout capability. Finished WG is used both in hot state immediately after production and as cooled for various foundry and metallurgical purposes.

A.V. Koltygin et al. Measurement of Thermal Properties of Molding Materials when Making Foundry Molds by the Three-dimensional Printing Method
Thermal conductivity and thermal capacity of molds made by the three-dimensional printing method have been calculated experimentally. Samples produced on printers by two different producers: ZCorporation (ZPrinter 310 model, ZCast powder) and ProMetal (S-15 model, S-15 mixture) have been examined. It has been found that ZCast mixture has a 1.3 times lower thermal conductivity and an almost 1.5 times lower thermal capacity as compared to S-15 mixture, which must be taken into account in developing casting technology using those materials.
