Vertical Injection

A new concept of microinjection molding module was designed and presented. The module was designed as a multi microinjection module, which is matched with a vertical injection molding machine (IMM) and can be applied to usual IMMs. A planetary gear pump was integrated in this module to complete the multi microinjection molding(MμIMM)。The module is fixed between the stationary platen and the mold of IMM. The plasticizing unit of the IMM provides the melt and initial pressure for the multi microinjection molding module. With this module, a usual IMM could be upgraded to a precise microinjection machine and has the capability of precise metering for the microinjection molding.

Behavior Characteristics

A planetary gear pump (PGP) was introduced to the differential injection molding. The system is matched with a vertical injection molding machine (IMM). The PGP is integrated in the stationary mold and is fixed between the stationary platen and the movable mold of IMM. The dynamic mesh technology in the software packages Fluent was applied to investigate the melt behavior. Characteristics of the PGP, such as pressure and injection volume, used for the DIM process were studied

Selection Of

This study focuses on fabrication of a micro plastic part using custom made vertical injection molding machine. Electrical discharge machining (EDM) and micro mechanical machining was used to fabricate micro shape cavity on aluminum mold. The mold was embedded with Polymethyl Methacrylate (PMMA) window to observe the behavior of plastic melt flow during injection. The custom made vertical injection molding machine has capabilities to produce a micro plastic part. But, the filling behavior observation was contrast with MoldFlow analysis software. The flashing problem occurs at each molded micro part due to improper selection of injection molding parameter.

The Stability

Background: One of the most common manufacturing equipment for polymer product is injection molding machine. In order to ensure the precise, stable and continuous operation of the injection molding machine, the maintenance of the lubrication system must be done well. The stability, reliability, rationality and low noise performance of the lubrication system of injection molding machine directly affect the quality of injection products, dimensional accuracy, molding cycle, working environment and maintenance. Objective: The purpose of this study is to introduce the methods of choice, maintenance of lubricating oil for injection molding machine from many literatures and patents in the recent years, such as lubricating oil device, lubricating composite and structure. Methods: An example of the 260M5 automatic injection molding machine is introduced for the inspection and maintenance of the lubrication system including lubricating oil and lubricating grease. Results: To ensure the lubrication of the injection molding machine, it needs to strictly observe the lubrication time and modulus of the injection molding machine. It needs to strictly control the temperature rise of the lubricating oil and select the correct lubricating oil and grease to ensure the lubrication quality. Conclusion: In the operation of the injection molding machine, it is necessary to check that the lubricating oil is sufficient and the lubricating points are working properly. It ensures sufficient lubrication of the injection molding machine and strictly observes the lubrication time and modulus of the injection molding machine. The stored lubricating oil should be sealed well to prevent air pollution.
