This large gold mine in Mexico was the perfect challenge for the new GEOSTAR wedge welder from Leister. The high welding speed of the GEOSTAR wedge welder is an economic solution for the lining of heap leach pads, lakes or landfills.

With high quality equipment and friendly Leister service, users experience maximum productivity even under extreme environmental conditions.

Modern plastics have become a part of our everyday lives. One can even go as far to say plastics consumption is a benchmark for measuring how developed a country is. According to Plastics – the Facts 2014/2015, a report published by PlasticsEurope, “...plastics materials have been key enablers for innovation and have contributed to the development and progress of society.”

​Plastic parts, manufactured using the injection molding process, can be realized in essentially every industry in many different ways. In an extremely competitive market where there are over 16,000 injection molding and plastics manufacturing facilities in the U.S. alone; part quality, appearance and especially consumer safety are at the top of the list to even be considered a viable candidate to produce these everyday items used throughout the world. 

In October 2013, two companies based in Ulaanbaatar, Mongolia, Bayan Airag Exploration LLC (a mineral exploration and development company), and Usny Erchim Co., Ltd (Leister Technologies’ official sales partner), found themselves at the Northwestern region of Mongolia collaborating on the Golden Hills Heap Leach Project.

Heap leaching is an industrial mining technique used when extracting precious metals―like copper, uranium, gold, and other compounds—from ore via a series of chemical reactions.

The ore is first crushed and then “heaped” into large piles on plastic sheets which protect the soil against contamination. Once the solvent (typically cyanide) seeps through the piles of material, and bonds with the metal contained therein, the solution is then collected at the bottom of leach tanks as an enriched solution and pumped to a mill where more chemicals are used to separate the cyanide from the valuable metals. Therefore, it is of extreme importance that those plastic layers are absolutely leak-proof.

Similar to a catered event, projects are meticulously planned affairs that are prepared “a la minute,” or to the customer’s order. It can require a smorgasbord of collaborators that crosses datelines and cultures. An example of such an undertaking brought the teams, from Horequip and Leister, together to team up and serve Puff ‘n Stuff Catering with their newest location.

Tampa-based Puff ‘n Stuff Catering started as a small pastry shop in Trinidad in 1971. Since 2003—under the watchful eye of the founders’ son, Warren Dietel—Puff ‘n Stuff Catering has grown from a small pastry shop, to a large, full-service catering company who continues to win over its clients with its attentive service and exceptional cuisine.

Upon completion, the Kusile power station, located in the Mpumalanga district of South Africa, will become the fourth largest coal-fired power plant in the world.

This station, with a total capacity of 4,800MW, is part of the Eskom group (South African public electric utility) and will be the first power station in South Africa to install flue-gas desulphurisation (FGC) to remove sulphur oxides (SOx) from exhaust flue gases. 

The search for the most environmentally-friendly solutions not only included the production of electricity itself (once the electricity will be running through the high voltage lines), but was also a concern long before the opening of the power station.

The floor covering of a room has a considerable effect on the people who live within it. Its function, material texture, as well as its color or pattern, are the factors which determine the level of quality of use.

The Better Choice
Resilient floor coverings no longer correspond to the dusty cliché of those depressingly functional wastelands they once used to be.

Modern floor coverings elegantly master the balancing act between functional requirements like hygiene, safety, appearance and cost-effectiveness, thus providing limitless possibilities to any creative interior designers

Swiss Federal Railways (SBB) was confronted with the torment of deciding on a suitable flooring, when renovation of the employees’ recreation and dressing facilities at the Lucerne site were due. The choice finally fell on a red, discreetly marbled PVC flooring, which was supposed to be laid from the entrance to the lounge area as well as the wet zones.

​With over 40,000 square meters (430,556 square feet) of shade structure products, Egypt-based shade specialist, FTH-Industries, delivers standalone shade structures to schools for playground areas, sun covers, shade canopies for car parks and industrial shading structures.

FTH-Industries uses heavy-duty materials—HDPE fabrics as well as PVC tarpaulins—in their shade structures. Until recently, the traditional sewing application for large and heavy items, like tarpaulins, consisted of using rings to connect ends.

However, a problem often recurred when connecting more than one fabric roll to produce larger spans: To achieve reliable connections, the staff at FTH-Industries needed at least two sewing passes, which regularly resulted in lower outputs due to this time consuming procedure.
Another problem lay within the thickness of the PVC tarpaulins: For larger spans, 750 to 900 gram (22 - 26.5 ounce) material and higher were used. Now, imagine the difficulty of moving this weight through a sewing machine! Use of thick UV-treated threads did not make the job easier.
