The process of stamping metal stampers has come under increasing scrutiny in recent years, with the metal industry seeing a rise in metal stamp contamination in recent months.
The metal industry has now become the most contaminated metal stamp industry in the world, according to a new report from metal stamp experts at Johns Hopkins University.
The report found that metal stamp companies are finding it increasingly difficult to get metals onto the stamp, due to increased levels of metal contamination, and that companies have been forced to increase their stamping costs to try to get metal onto the stamps.
“The metal stamp process is becoming more and more complex, and the stamping industry is paying a premium for these processes, as metal contamination increases,” said Dr. John Condon, co-author of the report.
“So it is becoming increasingly difficult for companies to get the metal onto their stamps, because there is so much metal contamination on the metal stamp.”
The report comes as the UK Government and the Department of Industry and Science are also looking at ways to improve the stamp quality.
“We are concerned about the increase in metal contamination of metal stamp materials, and have made progress in reducing metal contamination in metal stamps,” said a Department of Commerce spokesman.
“However, the industry needs to continue to invest in reducing its risk profile and the risks associated with the use of metal stamps.”
Metal stamp companies have also been the subject of some controversy.
In March, the UK’s biggest metal stamp company, Fingertip, was fined £500,000 after failing to disclose that it had been fined for not properly checking metal contamination levels on metal stamp paper.
A month later, Fong Stamp, a metal stamp manufacturer, was ordered to pay £1 million in damages to the UK government after it was accused of breaching the EU’s strict stamping regulation by using a cheaper method of stampmaking than is recommended by the metal standard bodies.
Fingertips and Fong are both involved in the metal stamps industry.
In the report, Condon and his co-authors argue that the UK metal stamp standards are still not sufficiently rigorous.
“At the moment, there is very little evidence of metal-to-metal contamination being removed from metal stamps, even though the industry is now reporting a rise,” Condon said.
“This is not just due to the rise in contaminants on metal stamps – we also see that the metal-manufacturing companies are struggling to comply with metal standards.”
Metal-to, metal-out stamping is a process in which a stamping material is added to a stamp and then the metal is removed from the stamp by a machine.
Condon says metal-in stamping has become less common in recent decades, as manufacturers have switched to cheaper, less reliable methods of stamp fabrication.
“While metal-ins is more prevalent, the rate of metal removal on metal-outs is significantly higher,” he said.
Metal-in and metal-down stamping are two different processes.
Metal-in is used on metal pieces that are then stamped onto paper with a machine that uses heat, and metal is added back onto the paper.
Metal stamping with metal-based components can result in more metal contamination.
