Iranian Firm Uses Plastic Injection Method to Produce Delicate Parts for Toy Industry
“One of our research areas is the application of plastic and composite injection industry in the toy industry. In this field, we have come up with three new plastic injection methods from a combination of composite injection and plastic injection, two of which do not require a plastic injection machine and the process has been developed in our company,” said Reza Khosravi, a researcher at the company.
“In the third method, we design and manufacture molds for plastic injection for the machine,” he added.
“The molds that we developed for the plastic injection are of higher quality than the existing molds, while the greatest delicacy can be created in the molds at the lowest cost. Its low price compared to existing molds is another competitive advantage of this product,” Khosravi said.
In a relevant development in 2023, a group of Iranian researchers had also used a substance based on MRF fluids, with application in military industry, to produce toys and entertainment tools.
“One of the plans of the research group is production of materials based on magnetorheological fluid or MRF which is a fluid that takes special arrangements in the presence of magnetic fields and can have different applications,” said Masoud Azimian, one of the researchers.
He explained that an application of these materials is polishing the surface of military lenses, adding that now these fluids are used in production of toys and entertainment kits.
“We produced slime paste from MRF fluids in the presence of magnetic fields. This paste will take different shapes inside the MRF fluid and under the magnetic field,” Azimian said, noting that these fluids are manufactured based on iron nanoparticles.
Magnetorheological (MR) fluids are a class of smart materials whose yield stress increases considerably in the presence of externally applied magnetic field.
