Injection molding is a manufacturing process for producing parts by injecting material into a mold. Injection molding can be performed with metals, glasses, confections, and plastic thermoforming. Material for injection molding parts is fed into a heated barrel, mixed, and then forced into a mold cavity where it cools and hardens to the specifications of the cavity. After an engineer […]
Harmonic Distortion is any distorted voltage and current waveform that deviates from an ideal sinusoidal waveform. Harmonic distortion presents potential harm and equipment downtime to electrical components. Non-linear loads connected to the electrical supply in facilities cause harmonics (waveform distortions) on the power distribution system. Common non-linear loads include solid state motor soft starters, variable frequency drives, […]

Drive system integration is becoming more complex and demanding with technology. Manufacturing in the future will be much more resourceful than today’s factories. Manufacturers must reach increasingly higher rates of productivity and efficiency at the lowest possible cost. At the same time, the next stage of industrial manufacturing is just around the corner: Industry 4.0; an initiative known as the […]
Variable frequency drives save labor and reduce energy costs while extending the lifespan of equipment for industrial applications. In the following ABB case study, a farm owner began looking tor alternatives to an old irrigation system, which worked by running the water pumps at constant speed, with control than being done by manual opening and closing of valves In […]

The mining industry is challenging, and ABB operates accordingly to the highest standard of occupational health and safety excellence and remains constantly vigilant in carrying out its duty of care. ABB’s combined efforts and commitment allows it to achieve a continuing improvement in its safety record. The machines and equipment used in mining must provide […]
In the past, applications operating at less than 300 rpm, and rated from 500 kW to 5000 kW, have been controlled using a medium-voltage constant speed synchronous motors. Common applications include crushers and various mills used in metals, cement or mining. Replacing a constant speed with variable speed drive control brings substantial operating and maintenance improvements. Variable-speed drives provide soft starting, […]
Today, VFD machine safety technology is making the previously-complicated job of implementing a machine safety system much easier. Recent technical advances make safer operation less complex, while at the same time offering new potential for productivity. New developments in drive-based functional safety contribute to greater overall protection of people, machines and ecosystems. The aim is […]
