POLAK limited company came into existence on Oct. 1, 1992 on the basis of privatization and followed up on the rich tradition the beginning of which is dated back to 1919. In that year Mr. Josef Polák established the company named POLAK.
That company, having its place of business in Praha, aimed its efforts at the development of machines and technology of metal pressure die-casting. The invention of a die-casting machine with a cold vertical filling chamber in 1927, for which Mr. Polák was granted the patent, meant a fundamental importance. The patent soon spread in all advanced countries and in 1930 the licence for the production of these machines was sold to Germany and England. In 1935 the production of machines was extended by the production of dies and castings. In 1939 Mr. Polák died.
At the beginning of sixties the production of die-casting machines was brought to an end and the production of dies extended. Products of the company have been known in Germany, Austria, Sweden, Norway, Finland, Canada, USSR, India, Egypt, Australia and many other countries. The company existed in the below mentioned years under the following trade names:
1919 - 1939 POLÁK
