Estudo de viabilidade técnica da alteração de um molde de injeção direta para câmara quente na produção de um manípulo de fogão
(Universidade Tecnológica Federal do ParanáPato BrancoBrasilDepartamento Acadêmico de MecânicaEngenharia MecânicaUTFPR, 2018-11-12)
The present study analyzes the technical viability of the change in a thermoplastic injection mold in the production of a stove knob, with the replacement of direct injection technology by hot-chamber injection. It presents ...
Caracterização da matéria prima na fabricação de puxadores na indústria moveleira
(Universidade Tecnológica Federal do ParanáLondrinaBrasilEngenharia de MateriaisUTFPR, 2016-11-07)
Thermoplastic consist of one class of polymer, when compared with these metals have low mechanical strength. To improve this characteristic, the blends can be produced which consist of a physical mixture of two or more ...
Adhesion control for injection overmolding of polypropylene with elastomeric ethylene copolymers
(John Wiley & Sons Inc, 2009-06)
Two types of random semicrystalline copolymers (ethylene–octene and ethylene–butene) were overmolded on a core polypropylene. Maximum solid–liquid interface temperature achieved for the overmolding injection process is ...
Metallic powder injection molding using low pressure
(Elsevier B.V., 2001-12-03)
The demand by high performance materials that have to support severe service conditions at a reasonable cost has been forcing the powder metallurgy to improve constantly. The most recent and more important innovation in ...

Análise da influência de parâmetros do processo de injeção utilizando simulação computacional
(Universidade Tecnológica Federal do ParanáCuritibaBrasilGraduação em Engenharia MecânicaUTFPR, 2019-06-26)
Injection thermoplastic polymer processing industries have been continuously adopting CAE (Computer Aided Engineering) on parts and molding development, aiming for design flaws correction before tool execution (mold). The ...
Characterization of PP/TPV/MMT Ternary Nanocomposites Produced by Injection Molding
(Wiley, 2017-06-22)
One of the most valued and required features of new polymers are a high level of stiffness combined with good toughness. In this way, it seems useful to combine nanoclay reinforcement with rubber toughening to balance end ...
Aplicação de zamac-8 em molde-protótipo usinado e análise do moldado em polipropileno
(Universidade Tecnológica Federal do ParanáCuritibaPrograma de Pós-Graduação em Engenharia Mecânica e de Materiais, 2011-10-31)
The reason for the existence of a prototype mold is to obtain a quickly injected with the same material and using the same manufacturing process of the final product with low cost. Their models can serves as prototypes, ...
