History of The Injection Molding industry

– FOAM MOLDING: Introducing: Definition: ‘Any polymer process which gives a partly or fully foamed product.” (Science dictionary) Foam molding is a manufacturing process that creates parts of a product and artefact made out of foam. The foam molding process consist of mixing foaming agent and base resin in melted polymer, creating a mixture that will be injected into a mold, that will solidify and become a part or an object. History: In 1872 the American inventors John Wesley Hyatt and his brother Isaiah Hyatt patented the very first injection molding machine…. ;

An Exploration of Molding

– DEFINITION Molding can be defined as the process of manufacturing by giving a particular shape to a liquid or a pliable raw material using a rigid frame called a mould. A mould is a hollow box which is made from a pattern. While working a mould is filled with raw material like plastic ,glass, metal etc. The liquid cools down into the mould and gets harder adopting its shape. TYPES OF MOLDING • Injection molding • Foam molding • Extrusion molding • Compression molding • Blow molding • Matrix molding • Plastic molding Vacuum plus assist molding INJECTION MOLDING DEFINITION It is a process for giving a particular image to a pliable raw… ;

Injection Molding

– Plastics Engineering Injection Molding Most people have never heard of injection molding, however the products that are produced through this process are as common as a toothbrush, a compact disk, or even drinking glasses. Injection Molding is one of the principal processes used in converting plastics into useful products. An injection molding machine can be large or small but work through the same general process. The machine heats a thermoplastic material that in its pre-processing state is pelletized or granular, to a liquid-like “flowable” state…. ;

Safe Injection Sites (SIS) in Canada

– Harm reduction strategies in Canada, such as safe injection sites (SIS) have been proven to be an effective strategy to control the effects of injection drug use (Small et al., 2011). The proven effectiveness of these strategies renders the governments’ “war on drugs” and criminalization strategies ideological. The Toronto Board of Health meeting that took place on July 10, 2013 where public health officials, community organizations, previous injection drug users (IDUs) and their families spoke in favour of opening a SIS…. ;

injection molding

– Wilbert Plastic Services In the early days manufacturers came to us for a specific thermoformed or injection molded part or parts for a product they were making. Over the years we noticed that, more and more, they were coming to us for entire subassemblies and more complex parts that might incorporate both thermoformed and injection molded parts. Based on that experience, and our knowledge of the pressures that manufacturers are under to increase efficiency and reduce cost, it became obvious to us that we needed to provide a wider array of services to help our customers increase their efficiencies, reduce their overall costs and maximize their ROI on each project, part or component…. ;
