During the 3D printing process of parts, very small cavities inside will form pores. These micro-holes will reduce the overall density of the part, leading to cracks and fatigue problems. It can adopt the mode of laser partition scanning and can also reduce the amount of pores. Reduce powder splash by adjusting the shape of the spot.
Pay attention to the following points during operation of the gas boiler:The boiler does not allow positive pressure combustion or smoke emission from the furnace, because it is easy to burn out the coal filling hole cover.
From the analysis of several aspects such as the connection of the plate bending machine, the stress status, and the process of the plate bending machine, it can be seen that the single-sided radial clamping has the following advantages:
The laser cleaning technology in the laser cleaning machine refers to the use of high-energy laser beams to irradiate the surface of the workpiece to cause the dirt, rust or coating on the surface to evaporate or peel instantly, which can effectively remove the surface attachments or surface coatings to achieve cleanliness purpose.
The swamp excavator is a fixed asset with a large economic investment. In order to increase its service life and obtain greater economic benefits, the equipment must be fixed in terms of personnel, machines, positions, and responsibilities. When the job must be transferred, the equipment should be disclosed.
Because the laser marking machine is small in size, easy to operate, maintenance-free, long service life, high stability, and the price of the equipment is getting lower and lower, it meets the needs of many manufacturers' production and development, and gradually replaces other processing in the market. Marking equipment. Many people hesitate when purchasing laser marking machines.
uhf rfid tag, also known as radio frequency tag, realizes the spatial (contactless) coupling of radio frequency signals through the coupling element between the electronic tag and the reader, and realizes energy transmission and data exchange according to the timing relationship in the coupling channel.
FRP guardrails are divided into general section anti-collision guardrails and bridge guardrails according to the road section; according to the installation position, they can be divided into roadside guardrails and central divider guardrails; according to their mechanical properties, they can be divided into rigid guardrails and semi-rigid Three methods of guardrail and flexible guardrail.
Generally speaking, the application of cone calorimeter can obtain multiple performance parameters of combustion samples, such as heat release rate, mass loss rate, smoke generation rate, effective heat of combustion and ignition time, as well as the toxicity and combustion gas Corrosion etc.
To maintain the waterjet cutting machine, the maintenance personnel need to clean the equipment after the processing is completed every day, so that the machine tool and the guide rail are kept clean;
