Medical equipment vacuum-formed shell Usually made by low-pressure injection molding. Low-pressure injection molding is produced through simple molds (such as aluminum molds, resin molds, and ABS molds). Resin molds are more commonly used because the cost of resin molds is lower than that of aluminum. The speed of mold making is faster.
Low-pressure injection molding is suitable for small-batch trial production in the product development process. This type is mainly used in the automotive industry, as well as for products with large-scale production and uneven wall thickness, which are produced in small batches and have a simple product structure. This type is mainly used for medical equipment vacuum-formed shells, similar to medical cart shells, instrument shells, reagent equipment shells, car bumpers, and car hoods. ABS vacuum forming, TV shell vacuum forming etc.

Since these products usually do not have many products, if the injection mold is opened, the cost will be relatively high, and many products need to change the product structure design before injection molding. The vacuum-formed shell injection molding process mainly uses steel molds to produce a large number of products on beer machines. The medical equipment vacuum-formed shell injection molding process is suitable for products with relatively small sizes and large product output.
Medical equipment vacuum-formed shell Technology is a key technology that sheet metal technicians need to master, and it is also an important process for sheet metal product forming. The processing steps of medical equipment vacuum-formed shells are basic processing, cutting, bending, rolling, local Vacuum forming processing , processing equipment and new technologies.

Starting from the basic principles of processing, processing flow, and materials used, through punching, punching and melt cutting, stretch bending, roll bending and press bending, rolling spinning and bulging processes, to various processing equipment and new technologies. It is completed by actual parts, typical components, and commonly used equipment in production.
Besides Medical equipment vacuum-formed shell In addition to the strict requirements in the production process, quality inspection independent of production is also required. One is to strictly check the dimensions according to the drawings, and the other is to strictly check the appearance quality. Those with inconsistent dimensions will be repaired or scrapped. Scratches on the appearance are not allowed. After spraying, test the color difference, corrosion resistance, adhesion, etc.
