When producing a profitable plastic bottle using an existing injection blow molding machine, the size and shape of the bottle are limited. There are several types of injection blow molding machines available on the market, which differ in the way they transfer the core rod from one segment to the other, including the ribbed, two-segment (rotary), axially movable and three-stage And three or more rotating types. Injection mould Today's three- or four-stage rotating machines are popular.
This type of equipment can be divided into two categories: blow molding assembly, which can be installed on some industrial injection molding machines; and complete injection molding equipment with a plasticizer, hydraulics, controls and Other accessory parts. These devices can be further distinguished as: vertical reciprocating screw presses and horizontal reciprocating screw presses.
The vertical type is much simpler than the reciprocating type. When the injection volume is the same at the same filling speed and lower injection pressure (if necessary), it has fewer parts, less energy consumption, less floor space, and easier maintenance.
The reciprocating screw-type plastic mixer is mainly developed for injection molding; although its structure is more complicated than vertical, the reliability of operation is good.
