Casting process molding can be an expensive process.
It requires a skilled technician to produce the moulds.
Now researchers in the UK have developed a new moulding technique that can produce moulds from just one type of mould.
The scientists, from the University of Sheffield and the University College London, have used a moulding method that can be used to produce mould of any size.
The moulds produced by this new method are made by adding an alloy of carbon and titanium, which are both commonly found in metals.
It’s a process known as thermo-molding and is relatively inexpensive.
The researchers say their method is simpler, cheaper and easier to work with than the traditional process, which requires a machine that can mould metals or chemicals.
The process is called thermo molding and the researchers have dubbed it the mould-making process.
They have published their results in Nature Materials.
Dr Sarah Sillitoe, one of the lead authors, said the researchers were interested in moulds made from plastics.
“We wanted to find out if it’s possible to make moulds that are actually biodegradable, so that you could put them into an environment that is clean and that is not in contact with the environment around you,” she said.
“This is what we found out when we made moulds of plastics.”
The researchers have used carbon and tin as the two materials that they used to make their moulds, but Dr Sillinoe said they were using other metals as well, which they had not done before.
She said the process is not yet fully understood.
“It is interesting that it’s been done, because this is the first time that it has been done by using an alloy that is available commercially,” she explained.
The team of researchers hope that their method will eventually be used in other industries, such as in medical devices and medical implants.
“For some applications it’s a way to make plastic moulds and then later we will find that they’re biodegradeable, which is really exciting,” Dr Silleroe said.
