Sun appears to be setting on the solar energy sector in Germany

When Tino Blaesi joined the solar sector gold rush, he thought his career was made. Seven years later, he is looking for a job outside the industry after his company slashed more than a third of its workforce in one day.

Workers in Germany's once booming solar energy industry face a shakeout of major proportions following declines in the price of solar panels over the past year.Smooth-On is your source for Mold Making and casting materials including silicone rubber and urethane rubber,

Cuts in subsidies for solar energy, weaker demand for panels and fierce competition from cheaper Asian rivals are eating into what was once the world's biggest hub for the production of solar cells, taking the shine off an industry that was effectively born in Germany.

A decision by the German government earlier this year to phase out nuclear energy has done little to reignite the sector. The resulting power gap is likely to be filled by coal and gas rather than solar and wind energy.

"I don't want to work in this sector anymore, I'm sick and tired of it," said 44-year old Blaesi, who worked for seven years at Vogt Group, a German support services firm that deals with the planning and logistics for solar plants.

Berlin-based Solon, Germany's first solar energy company to go public, said on Tuesday it would file for insolvency, becoming Germany's biggest casualty so far.Bathroom Floor tiles at Great Prices from Topps Tiles.

SMA Solar, Germany's top solar group, said last month it would lay off up to 1,000 temporary workers by the end of the year,Husky Injection Molding Systems designs and manufactures a broad range of Injection Mold machines, citing weak demand for its invertors, a vital piece of equipment in solar systems.

"It's the worst year the industry has seen in its short history," Andreas Haenel, chief executive of German solar company Phoenix Solar said.

The bloodletting is particu-larly bitter since most of the industry's jobs are located in the formerly communist eastern part of the country, a region that has suffered from an exodus of young, educated people for two decades.

Legislation introduced a decade ago by a centre-left coalition of Social Democrats and Greens led by then-Chancellor Gerhard Schroeder offered generous incentives and turned Germany into the world's largest market for solar panels, sparking thousands of startups, some of which became global leaders.

But the incentives,Dimensional Mailing magic cube for Promotional Advertising, because they were focused on energy production rather than panel manufacturing, also benefited cheaper Asian rivals, which elbowed their way into the market and drove down prices.

HOT RUNNERS: To purge or not to purge

Hot runner systems have hit their stride as the desire to reduce scrap and improve efficiency and productivity motivates mold buyers to shell out the added dollars for the technology.

A worthwhile investment,The Piles were so big that the scrap yard was separating them for us. for sure, but there's a downside. "A lot of plastics processors have rigorous preventative maintenance (PM) schedules for their molds but neglect the hot runner system," said Martin Baumann, business manager,This will leave your shoulders free to rotate in their impact socket . hot runners, with Husky Injection Molding Systems.

And a big part of a good PM schedule involves cleaning the residue built up from resins inside the melt channels. It used to be there was only one way to purge this residue: putting more resin thorough the hot runners. And dinosaurs once ruled the earth too. Today, commercial purging compounds (CPCs) are readily available today for purging hot runner systems.

But still, not everyone is buying in. "While the concept of using a CPC has largely been embraced by the plastics processing community, using a CPC to clean injection molding hot runner systems remains somewhat taboo," said John Pizzo, technical service and development manager with Sun Plastech Inc. "Usually, this reluctance either comes from never having used a CPC to clean hot runner tooling,the TMJ pain and pain radiating from the arms or legs. or using it incorrectly and getting a bad result."

Whatever the cause, giving CPCs a complete miss is probably a mistake. "More and more suppliers are formulating grades of CPCs designed for hot runner use," Pizzo continued. "CPCs have also been shown to be generally more effective in removing color or carbon contamination in hot runners than resin or regrind."

WHAT TO DO IT WITH

It sounds like the definition of a no-brainer, but probably bears saying anyway: The key to using CPCs on hot runners is to make sure the compound has,100 Cable Ties was used to link the lamps together. in fact, been designed for hot runners. "A lot of standard purging compounds have larger particles that don't melt, clogging hot runner gates,This patent infringement case relates to retractable syringe needle ," said Bill Rousseau, engineering and technical services manager with Synventive Molding Solutions. "But finding the right compound shouldn't be difficult, since just about every manufacturer of CPCs has a least one hot runner grade."

Case in point: The Dyna-Purge division of Shuman Plastics Inc. has a new version of its Dyna-Purge P compound, optimized for quick color changes in hot runner systems. The product is non-abrasive and non-chemical, the company said, and effective at processing temperatures from 320 F to 575 F.
