Blisks are single-engine component composed of a rotor disc and blades through machining from a solid piece of material or blades to the rotor disc. These are one-pieced parts for compressors in aerospace applications. Its advantages include remove the need to attach the blades to the disk and thus decreases the number of components within the compressor while at the same time decreasing drag and increasing efficiency of air compression within the engine.
Blister Packaging is the method of packaging where goods for sale such as toys and electrical items are contained in between a specially made paper blister board and clear PVC plastic. Blister packaging of products involves material feeding, blister forming, product loading, sealing, slitting or perforation and cross cutting. The simplest equipment uses blisters that are preformed on a separate machine. The product is inserted into the blisters by hand and sealed. Thermoform fill seal machines can form blisters, load product into the blister, seal and cut them apart. Some machines can also automatically pack the finished packages into cartons. The sealing temperatures used in the machine will vary from 140°C to 200°C for non-continous machines and 200°C to 300°C for continuous packaging machines.
Block & bleed valves are back seated block valve along with a bleed valve with directional discharge tube and stem stop. It allows pressure to be bled and blocked for simplified instrument removal using a gauge. The discharge tube enables the technician to direct the high-pressure fluid away from changing the instrument. It can also be threaded into a hex primary block valve to provide secondary block and bleed functions on multiple instrument installations.
Block Cylinders are used as building block for pick & place. These are used as a built in magnet for sensor applications. These are sized with 8-25mm bore. These are calculated by metric or inch threads. It has 303 stainless piston rods. These are available in single and double acting versions with bore sizes from 16mm up to 200mm. They can operate at pressures up to 500 bar and produce forces up to 1,570 kN. The range includes steel, bronze and aluminium body types with various mounting options including manifold versions.
