Plastic suction processing technology for medical equipment shells

The plastic suction processing of medical equipment shells is a delicate technical activity, which has high tolerance requirements for the appearance, color, product size, built-in fixing parts, screw holes, etc. of the product. In our professional terms, it is a very contradictory issue to use injection molding standards to complete through suction molding. Therefore, for manufacturers, it is indeed necessary to have rich practical experience and master a considerable amount of industry knowledge. On this basis, it is possible to better use this technology to process medical equipment shells that meet customer needs and provide stable shells for various medical equipment.
Medical equipment shell processing

The plastic suction processing technology for thick plates of medical equipment shells is a key technology that needs to be mastered in the production and production of medical instruments.

Due to the large size of the shell of vacuum plastic medical equipment and the small production quantity in the early stage, if injection molding process is used, the mold cost will be hundreds of thousands or even millions. In terms of product development cost, manufacturers are difficult to accept. Therefore, smart merchants will choose to complete it through thick film vacuum molding process, and later cooperate with processes such as hand board, CNC carving, bonding, polishing, scraping, and oil spraying to complete it. It is also an important process in sheet metal products.

The thick film vacuum molding machine is a key process equipment that uses plastic sheets as raw materials and uses vacuum suction molding technology to produce plastic parts. It uses thermoplastic sheets as raw materials, heats them to a softening temperature through an oven, and then uses the vacuum negative pressure between the plastic sheet and the suction molding mold to adsorb the plastic sheet in the thermoplastic state on the working surface of the suction molding mold before cooling and forming.

The principle of thick sheet suction molding is similar to that of thin sheet suction molding. It is the process of heating the positioned sheet metal through an oven to a softened state, and then forming a closed space between the suction mold and its surroundings to instantly remove air from the mold cavity. The sheet metal is tightly covered on the surface of the mold, cooled and shaped to obtain the product.

Blister forming is a cyclic process, each cycle mainly includes: feeding - heating softening - back blowing pre pulling - blistering - cooling shaping - demolding and taking parts. After removing the plastic part, place the sheet again (can be received or automatically) for the next cycle.
