Metal etching

Chemical etching is a common procedure done for the designing of jewelry. What is chemical etching process and what are the applications of etching process? This is a common question asked by people new in jewelry making procedure. In this article, we are going to see some among the main applications of etching process in chemistry. Introducing complex designs in metal parts may not be an easy task for new comers in jewelry making procedure. This condition can be reduced by making use of chemical etching process in jewelry making procedure. At present, majority among the jewelry designers are making use of etching process to alleviate their difficulties in jewelry making. Generally, etching process is done by going through a series of procedures. First procedure of chemical etching process is done by covering the metal with photo resist material so as to get CAD image. Unwanted material after coating the photo resist material is removed and the remaining sheet is covered with ferric chloride for the requirement of etching process in metal. Now the mask is removed and the remaining sheet can be suggested as an etched metal. Etched metal is renowned for its versatality. Flexible metal sheets are renowned for its ability to create complex designs. Traditional ornaments generally constitutes complex designs. This condition can be satisfied by making use of etching process in metal sheets. Which metal sheets can be preferred for etching process? This is another main query discussed while considering metal etching process. As per studies, metals like copper, brass and silver steel are generally used for the making of etching process. Apart from the above specified metals, there are many other metals like molybdenum and nickel that can be used as a material for etching process. Thickness of material is one among the main factors considered while discussing etching process in metal sheets. Common thickness provided by experts in etching process is 22 gauge and 24 gauge. Retention of metal property is a main factor considered while discussing etching process in metal sheets. Metal properties can be retained and this feature reduce money loss. At present, there are many designers online providing guidance regarding etching process. Majority among the designers suggest etching process in metal sheets as a way to safeguard money by reducing labor cost. Tooling equipment and cost of tooling is high for non etched metals. Hence feel free to select etching process prior to jewelry making.

The Declining UK Steel Industry

Once home to a vibrant steel industry, the United Kingdom is now struggling to come to grips with steel production that’s on life support. Taxpayer funds are holding up a bankrupt British Steel as the government negotiates with a potential buyer and over 4,000 workers’ jobs are in jeopardy. Fifty years ago, the industry employed about 270,000 workers. Since then, the work force has dropped by 80%. This is the bleak picture described by www.theguardian.com in a January 2, 2020 article entitled “What Went Wrong at British Steel?” and other recent posts.

How did the UK steel industry find itself in such a mess? The reasons are many and varied. The Financial Times article entitled “The Long, Slow Decline of the British Steel Industry” puts blame on “a history of poor management, lack of capital and ill-judged state intervention.” There’s also the expansion of the steel industry in China. This country now produces over 50% of the world’s steel. Unfortunately, there’s more bad news. In an article by Chris Rhodes entitled “UK Steel:. Decades of decline” published on www.commonslibrary.parliament.uk, Rhodes suggests that the prevailing tendency that has driven the downward fall of UK Steel will not depart any time soon.

Interestingly enough though, manufacturing is on the rise in the United Kingdom. According to “UK Manufacturing Statistics” from www.themanufacturer.com, the UK is “currently the world’s 8th largest industrial nation. If current growth trends continue, the UK will break into the top five by 2021.” Companies like Qualitetch, for example, a manufacturer of precision steel components for the past 25 years, has a national and global customer base that draws from the aerospace, automotive, defence, electronics, technology, medical device, telecommunications, and renewable energy industries.

An additional boost to manufacturing, according to Rhodes, is the highly skilled UK workforce along with the recent development of manufacturing clusters–geographical connections of industries, suppliers and institutions in a particular field. Their success is birthing the idea that maybe something like the clusters could take place in the steel industry.

One thing is for sure. If there’s a will to revive British Steel, there is a way. Analyzing past decisions, learning from mistakes, and moving forward with a strong, innovative plan can boost the outlook for this vital industry. Out of defeat can come victory. Never give up!
