The basic operation of dies are blanking, drawing, shearing, and bending. The precision die and stamping or a tool has specifically designed metal cavity on which the metal sheet is placed and this gives a preferred shape and design to the sheet. In this setting, upper part of the sheet metal stamping dies are connected to the press slide http://www.dongmumould.com/lpg-cylinder-mould/

Because of the low-pressure high-volume airflows they create, axial fans especially small axial fans are best suited for general purpose applications. For example, they excel at moving air from one place to another, cooling confined spaces such as computers, and cooling larger spaces such as work spaces. http://www.hongkefans.com/small-axial-fan/

As for characteristics and models of truck, it can also be devided into many kinds like light-duty truck, heavy-duty truck, special purpose truck, truck trailer, pickup truck, light-duty cargo truck, box truck, dump truck, heavy-duty lorry truck, truck tractor, etc. http://www.ownacechina.com/light-duty-truck/

For drugs delivered to patients in crystalline form, the physical properties of the pharmaceutical intermediates or active pharmaceutical ingredient (API) including crystal form, size and shape have the potential to impact bioperformance, particularly for low-solubility compounds, where the rate-limiting-step in drug uptake may be the dissolution of the API in the gut. http://www.purestchem.com/pharmaceutical-intermediates/

One of my mantras as a crafter and a product reviewer is "There is no BAD products- only finding the right one for the job at hand." And by and large, that is true. The only time when you really need to know "which is better than that" is when you have multiple choices in the same product category. http://www.subbuteo.com.cn/main-products/lithium-battery-hot-cutting-pen/

A butterfly valve regulates flow by starting, slowing, or stopping media. The disk opens and closes with a low-torque rotation of 90 degrees and works for any compatible application. Because they cost less and are lighter weight, the butterfly valve is often preferred over other types of valves. http://www.tfcvalve.com/butterfly-valve/triple-offset-butterfly-valve/

Another indispensible equipment is steel pipe printing marking machine. Companies that produce metal pipes, regardless of whether they are involved in construction, aerospace, electronics, etc., code these materials to enable traceability, display important production data, and prevent counterfeiting. These codes generally take the form of numeric lot numbers or machine-scannable bar codes. http://www.westwu-machine.com/automatic-marking-machine/steel-pipe-printing-marking-machine/

The bolts always work together with a nut. A nut fastener is a mechanical fastener with a threaded hole. It is attached to a bolt, screw or stud to provide a clamping force and prevent axial movement. For example, a bolt is inserted through two parts, with aligned holes, and a nut is then screwed onto the bolt. The shaft of the bolt prevents radial movement of the parts, while the head of the bolt and the nut together prevent axial movement. http://www.yuchaobolt.com/nut-fastener/

These wide coils are further processed using a range of manufacturing techniques such as slitting, where the wide coil is slit into a multitude of strands; this is where much of the confusion around the terminology comes in. After slitting, the stainless steel forms a batch of coils taken from the mother coil and these are referred to by many different names, including strip coils, slit coils, banding or simply strips. http://www.avicmr-steel.com/stainless-steel-strip/
