introduction：one、I got to know the biosafety cabinet Biosafety cabinets provide both sample and staff protection。The filtered clean air is blown down from the top of the safety cabinet，Through the work areaCaptured before reaching the staffs breathing area。The air flow will be filtered before it is released，The filtered air is normally discharged back to the laboratory。 Biosafety cabinets for all biosafety levels Biosafety cabinets can be divided into one level、Two and three categories to meet different biological research and epidemic prevention requirements。Level I biosafety cabinets protect workers and the environment without protecting samples。Airflow works like a lab fume hood，

introduction： The location of the gate Correct gate location Wrong choice of gate system type and，In addition to causing processing problems，It will also have a certain impact on the quality of plastic products。consequently，The design department must not underestimate the importance of gate location。 Designers not only need to carry out the design calculation of plastic products，Special attention must also be paid to the gating design of the mold。They must choose the correct gate system and the number and location of the pouring points。The type and location of the gate will have a greater impact on the quality of the product。 The choice of gate location will determine the following properties of plastic products： §Fill in the

introduction： Circular insert Multi-cavity injection molds are usually designed in this way，Turn hardened quality tool steel into round or rectangular inserts，Inlay in unquenched water，But as much as possible in a tempered template，The tempered steel can still be machined。Mold manufacturing should always take into account the use of inserts to secure the plate，This greatly reduces the deformation caused by quenching，Large formwork often deforms during quenching。Because the insert fixing plate is often bolted to another form，Therefore, the easiest way to secure the circular insert is to clamp the insert shoulder。In order to prevent circular arrangement or linear alignment of the inserts do not want some rotation，set
