A Study on the Mechanical Properties of Recycling PC/ABS Blends Produced by Vent-Type Injection Molding
Yoshihisa Nagao, Yongli Wang, Yuqiu Yang, Hiroyuki Inoya, Hiroyuki Hamada, May 2016
The mechanical properties of recycling PC/ABS blends produced by three kinds of molding conditions were discussed, including such parameters such as the cylinder temperature and the type of injection molding processes. Mechanical properties and the degradation rate with the increase of recycling times were investigated. The comparison of different cylinder temperature produced by vent-type injection molding was conducted, also the research between cent-type injection molding and non-vent-type injection molding, based on the detailed SEM observation on the fracture surfaces after Izod impact test. It can be found that, with the increase of recycling times, the material produced by vent-type injection molding machine demonstrated higher mechanical properties and lower degradation rate in mechanical properties than non-vent-type injection molding machine.
Advances in Adhesive Technology for Bonding Liquid Silicone Rubbers to Plastics and Metals
Paul A. Wheeler, Tarek A. Agag, Brian P. Carney, Rebecca S. Cowles, Douglas H. Mowrey, May 2016
LORD Corporation offers new adhesive solutions that effectively bond platinum-cured liquid silicone rubber (LSR) to various substrates directly in an injection or compression molding process. This technology does not require plasma treatment or other complicated and costly surface preparation steps. In this study, three new adhesive systems were tested to bond LSR to various substrates, including polycarbonate, thermoplastic elastomer, polyamide, and stainless steel. Parts were molded and peel tested. This process and product technology offers a number of benefits compared to existing technology, including enhanced design freedom, more robust processing, less surface preparation requirements, and environmental friendliness.
