Rubber thermoplastic stamp for investigation

Hits: 1246

       The 3D evidence collectors currently used by the police include plaster, clay, tracing solution, which are not only complex to use but also time-consuming, easily deformed, and expensive. PSU thus developed “3D natural rubber thermoplastic molder” to aid police work to collect necessary evidence such as tool marks and identification proofs.

       The natural rubber mold can be softened into clay form when heated at 75 Celsius degree. Once applied to copy target evidence, it only needs to be led cool for 10 seconds to obtain an indestructible and indelible 3-D models of evidence. The mold can copy bullet holes, traces of break-in by small tools, as well as identification evidence like fingerprints, teeth, etc.

       Natural rubber thermoplastic mold offers outstanding benefits including easy to use in the field, does not require a lot of time nor high-level skill, once cooled the mold is permanent, flexible, easy to travel. To promote rubber innovation in Thailand, the product has been developed to respond other demands. It’s low cost and competitive pricing enhance the product’s commercial potential. Police have utilized the thermoplastic mold to help with investigative work in many areas in the South. In addition, many organizations have expressed interests to apply its use in other fields like medicine, sports, environmental research, and construction.

       This research has been granted a patent number 11992 and also received multiple awards both in Thailand and abroad. These awards include honorary award from Malaysia Association of Research Scientists (MARS), Malaysia; silver medal from Korea Invention Promotion Association (KIPA); Special Prize in innovation for wealth group from National Research Council of Thailand (NRCT); winner of commercial innovation from Ministry of Science and Technology with Southern Region National Park.
