ELECTROPORCELANA GAMMA S.A., was founded in 1962 and is part of the Corona Group, a multinational group of companies founded at the end of the 19th century, which to date employs more than 9,700 people worldwide.

ELECTROPORCELANA GAMMA S.A. manufactures and commercializes electrical insulators, protection equipment and fittings, among others to utility companies, OEM's and electrical distributors.

The Company started exporting its products to the American continent over 40 years ago. The Company's main markets include countries, such as Colombia, United States, Venezuela and Mexico, as well as the South American region, Europe and Asia.

Its quality products, state-of-the-art infrastructure, human and financial resources and good understanding of the market has positioned the Company among the leaders in the manufacture of electrical equipment.

In 2001, the Company began commercializing its products to Lapp Insulators under their own brand in the United States and Canada. In September 2009, ELECTROPORCELANA GAMMA S.A. bought from Lapp Insulators the distribution business associated to its products for the North American market.

Raw Materials Analysis & Slip Formulation

Raw materials are categorized in terms of chemical composition, mineralogy, and physical and ceramic properties. These properties are used to create the optimum blend for high quality ceramics.

Ball Clay Beneficiation & Slip Batching

These processes use low and high intensity dispersers, hydrocyclones, sieves, and magnetic traps. Batching is carefully performed according to the weight and volume of the item.

Filter Pressing

Process in which high pressure is used to remove water from the conveyor belt to obtain flat plates with a consistent material density. Work pressure up to 200 PSI.

De-airing & Extrusion Equipment

Flat plates are de-aired in a vacuum pug mill. Final products are extruded with optimum compaction and homogeneity. Pug mill hole diameter up to 13”.

Wet & Dry Turning

Horizontal and vertical hydraulic lathes are available for shaping cylindrical pieces up to 1.2 meters long. Lathes are automatically controlled for the optimal sequencing of operations. Tungsten carbide tools with high wear resistance are used.

Pressing Process

A heated die is pushed while turning the extruded item inside a gypsum mold. Optional threading is available.

Drying & Firing Kiln

Gas fired dryers and kilns are suitable for water removal and ware sintering. Shuttle and tunnel kilns are available for temperatures up to 1300°C. Dryers support temperatures of up to 140°C.

Coating Process

Process in which a surface glass coating is applied on the item.

Assembly & Cement Setting Processes

Processes in which ceramic and metal parts are joined together using cement. Steam is used to speed up the cement hardening process, with temperatures up to 65°C.
