Extrusion
Extrusion is a process used to create objects of a fixed cross-sectional profile by pushing material through a die of the desired cross-section. Its two main advantages over other manufacturing processes are its ability to create very complex cross-sections; and to work materials that are brittle, because the material encounters only compressive and shear stresses. It also creates excellent surface finish and gives considerable freedom of form in the design process.

**Application**
When a single vacuum pump is not suitable for a specific process due to limitations in pumping speed or ultimate vacuum, the DYK series vacuum pump unit provides an effective solution. It combines a Roots pump as a booster and a rotary vane pump as a backing pump. The exhaust from the Roots pump is connected to the suction side of the backing pump, allowing for high pumping speed at higher vacuum levels. This system is equipped with an air-cooling system, cooling water system, vacuum valves, vent valves, compensators, and a vacuum gauge, making it highly efficient, reliable, and energy-saving. It can be designed and mounted on base frames for immediate use, or on trailers to meet customer requirements. The DYK unit is widely used in vacuum metallurgy, drying, welding, chemical processes, laboratories, power stations, and other industrial applications, especially for vacuum transformers and other electrical equipment.
**Features**
1. The Roots pump automatically starts with the backing pump via an electrical-contact vacuum meter.
2. The powerful rotary vane backing pump ensures sufficient backing pressure so that the diffusion pump can always achieve its full pumping speed and ultimate vacuum.
3. The system includes a vacuum valve at the inlet and a rough vacuum line (bypass), making it particularly efficient for rapid evacuation cycles.
4. The high-vacuum pump unit offers outstanding energy savings, high efficiency, reliability, and low power consumption.
**Technical Specifications**
Injection moulding is a manufacturing process for producing parts by injecting molten material into a mould, or mold. Injection moulding can be performed with a host of materials mainly including metals (for which the process is called diecasting), glasses, elastomers, confections, and most commonly thermoplastic and thermosetting polymers. Material for the part is fed into a heated barrel, mixed (using a helical screw), and injected into a mould cavity, where it cools and hardens to the configuration of the cavity. After a product is designed, usually by an industrial designer or an engineer, moulds are made by a mould-maker (or toolmaker) from metal, usually either steel or aluminium, and precision machined to form the features of the desired part. Injection moulding is widely used for manufacturing a variety of parts, from the smallest components to entire body panels of cars. Advances in 3D printing technology, using photopolymers that do not melt during the injection moulding of some lower-temperature thermoplastics, can be used for some simple injection moulds.
