Maestranza Wilde Ltda. was founded by Óscar Wilde Serrano in 1956. At the beginning it was only a parts machining shop that served a few but important clients such as Cía. de Cemento Melón (cement producer) and the now extinct Fundición Aceros Andes (smelter).


Starting in 1968 we began an investment plan to purchase equipment and machinery. Initially we acquired lathes and milling machines from Italy. In 1970 we installed the first vertical lathe and the company broadened its reach to serve the mining and aggregates industries. At that time we began machining and repairing bowls and mantles for large mining companies (5½- and 7-foot cone crushers) that were exported to Peru and Canada.


Repair and maintenance services for crushers began in 1974 for the equipment in Cerro Negro Plant. In 1978 we began repairing pneumatic drilling equipment in mines. In 1979 we started repairing, maintaining, and fabricating 7-foot crusher parts for CODELCO (Andina Division) and Anglo American (formerly Compañía Minera Disputada de Las Condes -CMD) for its Los Bronces and El Soldado plants. Afterwards we repaired mills in mining plants. All in all, we stayed six years in CODELCO locations and four years in Anglo American locations.


In 1990 we started conditioning, repairing, and selling crushers imported from Europe. In the year 2000 we expanded our facilities and started producing bronze wear parts for cone crushers. In 2003 we began producing and selling liners for 3- & 4-foot cone crushers.


In 2005 we gained the ISO 9001-2000 standard certification for crushers’ repair, manufacture and assembly processes. In 2009 we obtained re-certification under the ISO 9001-2008 standard.


In 2007 we embarked in an association with Trio Engineered Products, Inc. from the United States and became exclusive dealers and the only authorized technical service provider for the whole line of Trio products (crushers, feeders, screens, electromagnets, and other equipment for crushing plants) in Chile.


In 2012 we established a commercial partnership with Samson Mechanical Handling Ltd. from England (a unit of Aumund Group from Germany) to represent them in Chile and take over the technical support and service for its complete line of materials handling equipment (modular mobile conveyors, feeders (towable wheel-mounted and self-propelled track-mounted), stackers (radial and telescopic) and ship loaders).
