Medical moulds, various moulds and tools used in industrial production to obtain the required products by injection moulding, blow moulding, extrusion, die-casting or forging moulding, smelting, stamping and other methods. In short, a mould is a tool used to make moulded objects. This tool is composed of various parts, and different moulds are composed of different parts. It mainly realizes the processing of the shape of the article by changing the physical state of the formed material. Known as the "Mother of Industry".

Under the action of external force, the blank becomes a tool with a specific shape and size. It is widely used in punching, die forging, cold heading, extrusion, powder metallurgy parts pressing, pressure casting, and the forming and processing of engineering plastics, rubber, ceramics and other products. The mould has a specific contour or cavity shape, and the contour shape with a cutting edge can be used to separate the blank according to the contour shape (punching). The application of the cavity shape can make the blank obtain the corresponding three-dimensional shape. The mould generally includes two parts: a movable mould and a fixed mould (or a convex mould and a concave mould), which can be separated or combined. The parts are taken out when separated, and the blanks are injected into the mould cavity to form when closed. The mould is a precision tool with a complex shape and can withstand the expansion force of the blank. It has high requirements for structural strength, rigidity, surface hardness, surface roughness and processing accuracy. The development level of mould production is one of the important signs of the level of mechanical manufacturing.

Patients can rely on intravenous fluids and infusions to maintain daily health or save lives. An increasingly serious problem facing hospitals is the infection that may be caused by intravenous infusion. In order to improve the safety of patients, professionals have developed a special three-way plug valve. There are two main differences between the (MRVLS) plug valve and the competitor: one is a Luer-activated valve that acts as a barrier to bacteria; the other is a novel internal passage that ensures self-rinsing and minimizes residue. Elcam Medical needs high performance materials to achieve this goal. In order to meet such requirements, a series of polycarbonate plastics have been developed which have proven to be effective in the field of medical technology.


New security concept
The design of the MRVLS plug valve provides a new concept of safety. A special self-sealing valve prevents the infusion solution and other liquids from flowing back, creating an almost closed system. Original equipment manufacturers say this actually eliminates the known risks because open, difficult to flush and clean infusion ports can cause infection. The minimum residual volume and the internal volume of the punch through the inner circumferential passage are continuously flushed, forcing the fluid to flush the self-sealing valve. This helps prevent bacterial colonization. Completely flushing away the medication and air from the system increases patient safety, reducing the chances of drug interactions, unwanted residual drug management and the risk of air embolism.

Injection mould processing and manufacturing is actually very important in real life. Perhaps most people are most concerned about some manufacturing steps. So what are the steps in the actual process?



1. In the process of injection mould processing and manufacturing, you will find that before the mould design, the designer should fully analyze the existing product situation, and must consider the actual effect of the entire product, we have to take a look at the current situation combined with the actual situation Whether plastic products conform to the principles of injection mould processing, and at the same time, during the processing process, we also need to look at their needs and the geometry and dimensional accuracy of the designer during the entire product manufacturing process, as well as the appearance requirements, in this case We have to carry out the necessary discussions and try to avoid unnecessary complexity in the mould manufacturing process.



2. In the process of injection mould processing and manufacturing, it is necessary to consider the mould structure design. Generally speaking, there is a set of high-quality moulds, and not only need to have good processing equipment, but also have skilled mould manufacturing workers, which is also very important. The factor is that it is best for us all to have good mould design, especially for the quality of complex mould mould design, which occupies more than 80% of the mould quality. An excellent mould design itself is more likely to meet the premise of satisfying customers. Their cost performance is relatively low, and the difficulty of processing is gradually reduced, and the processing time will be gradually shortened.



Therefore, after mastering this point, it is recommended that you better understand more about the entire injection mould processing and manufacturing process. We basically need to understand each detail of each mould design and fully understand the use of each mould part. In the design process, please refer to the previous design, and to understand their mould processing or product production process, to learn from the experience and lessons, and to understand more about the entire injection mould workflow, and deepen the injection mould Relationship, we must understand the processing technology of all products, understand the characteristics and limitations of each product processing, and understand the results of mould design.



3. In the process of injection mould processing and manufacturing, it is recommended that everyone be able to determine the mould material and standard parts. We will then perform mould processing. When selecting, we must consider the actual selection effect of the existing mould materials. In the selection process, in addition to In addition to considering the accuracy and quality of the product, it is necessary to give the correct choice in combination with the actual processing and heat treatment capabilities of the mould manufacturer. In addition, it is necessary to effectively shorten the manufacturing cycle and use the existing standard parts for processing as much as possible. .



4. In the process of injection mould processing and manufacturing, in addition to the best structure and reasonable tolerance distribution in the design process, the processing of parts and assembly of the mould is also crucial, so the processing accuracy The choice of processing method occupies an absolute dominant position in the entire mould manufacturing process. The manufacturing error of the mould is basically about 1/3, so the error caused by the wear of the mould is almost 1/6, and these errors are all What we should pay attention to in the ordinary time, it is recommended that you choose a regular manufacturer such as Xubang for processing, so as to effectively avoid errors and achieve the desired effect.

The widely used type is the simple oxygen mask. The oxygen mask is used for non-life threatening conditions that may deteriorate. For example, if the patient is admitted to the hospital with chest pain, the doctor is likely to put on a simple mask.

It can be set to deliver a certain amount of oxygen to the patient, but the oxygen may be diluted by the air in the room. Therefore, if the oxygen mask is loosely installed, a large amount of air may enter and mix with oxygen.

There is a device called an oxygen concentrator that can be connected to a simple oxygen mask to help control the oxygen concentration. It can help, but it cannot fully control the oxygen flow.
