Make the Switch: The benefits of manufacturing medical devices from plastic instead of metal July 15, 2019 Are you on the fence between materials? Single-use plastics have gotten a bad reputation recently but we’ve outlined several benefits that plastics have over metal for medical devices. Sterilization Safety for both patient and practitioner is at the forefront of healthcare, so having sterile medical devices is paramount. According to The PVC Medical Alliance, single-use plastics prevent the reuse of devices such as syringes and needs; making it possible to eliminate most of the dangerous cross-contamination between patients, as well as the hospital staff. Ergonomics Plastic material is much lighter than metal, which reduces the weight of medical instruments. Reduced...

Overmolding and the Medical Device Industry February 21, 2019 What is Overmolding?   Overmolding is a process where a single part is created using two or more different materials in combination. Typically the first material, the substrate, is partially or fully covered by subsequent materials, or overmold materials, during the manufacturing process. The substrate provides structural support while the subsequent material is heated to its melting point and injected into the mold tooling as a liquid. As the subsequent material cools, it forms with the substrate. Overmolding is a type of Multi-Material Molding (MMM). According to MedTech Intelligence, MMM is a process “whereby at least one melt processible material...

Thermoplastic Elastomers: Manufacturing Medical Devices November 27, 2018 Medical device manufacturers have begun to use Thermoplastic Elastomers (TPEs) for applications requiring flexibility for a variety of reasons. They have a high degree of purity TPEs have gained popularity because of their high degree of purity, meaning a low level of extractable compounds. According to Flexible working: TPEs are materials of choice for medical devices, an article from Medical Plastics News, “Medical grade TPEs are made with FDA compliant raw materials and are free of phthalates and latex proteins. In addition, TPEs are inherently designed to have extremely low extractables or leachables, even when in contact with aqueous based...
