The rapid growth of the extrusion industry has increased the demand for extrusion machines and accessories.

Extrusion processes, including hot extrusion, cold extrusion and hydrostatic extrusion, is useful in the creation of objects of various shapes like solid round, rectangular, etc.

Various extrusions machines include Extruder, PP / TQ Film Plant, Extrusion Lamination Plant, Synthetic String Plant, and so on.

Plastic extrusion is very common, and involves melting and forming of raw plastic material into pipe / tube, window frames, adhesive tape, etc.

There are various types of plastic extruders, such as basic extruder machine, single screw extruder and twin screw extruder. These extruders are used to manufacture a wide range of products by extruding an assortment of plastic materials.

Variable frequency drives are widely used for retrofitting of plastic extruder machinery, mainly for reducing the energy consumption, thus saving the energy bill.

In modern society, domestic and commercial sewage treatment plants are common.

Frequency inverters from our company are widely used in municipal engineering for waste water treatment (sewage disposal, sewage treatment, sewage sludge treatment), such as sewage pumping and sludge dewatering.

Variable speed drives from Shenzhen V&T Technologies Co., Ltd. are an ideal way of regulating flow and pressure. The main benefit of using inverter drives in this field is energy saving. Also, smooth control during operation is achieved.

our VFD drives can help you to make significant energy savings when compared to traditional regulation methods.

For example, compared to a throttle-controlled fixed speed pump, energy savings of 50% are typical. Thus the payback time of the investment on VSD drives is sometimes just one year, even shorter.
