Medical machinery shell processing technology is the key technology that sheet metal technicians need to master, and it is also an important process of sheet metal products forming. The processing steps of medical machinery shell include processing basis, cutting cutting, bending, rolling, local processing, processing equipment and new technology, etc.

Medical mechanical shell from the basic principle of processing, process flow, the use of materials, through blanking, blanking and melting, bending, roll bending and bending, rolling spinning and swelling and other processes, until a variety of processing equipment and new technology, are completed by the actual production parts, typical components and common equipment.

In addition to the strict requirements in the production process, the processing quality is independent of the production quality inspection, one is to strictly check the size according to the drawing, the other is to strictly check the appearance quality, the size does not conform to the repair or scrap treatment, appearance is not allowed to scratch, color difference, corrosion resistance, adhesion and other inspection. Samples can be found to expand the diagram error, bad habits in the process, errors in the process, such as number punch programming errors, die errors, etc.

The processing of medical mechanical shell is usually carried out by low-pressure perfusion, because low-pressure perfusion is used to produce simple molds, such as aluminum mold, resin mold, ABS mold, resin mold is more commonly used, because resin mold is cheaper than aluminum, and the speed of making molds is faster.

Low-pressure perfusion is suitable for small batch trial production of the product development process, this type is mainly used in automobile industry, and small batch production of large products and product structure is relatively simple and uneven thickness of plastic products production, this type is mainly used for medical products similar to the medical car shell, shell of the instrument, reagent equipment shell, car bumper, car hood, etc., because these products often product quantity not too much, if open injection mould, the cost will be relatively high.
