Plastic injection molding machines are one of the basic components of modern production technologies. These machines, which are used in many areas of industrial production, are especially preferred in the automotive, medical, white goods and packaging sectors with high efficiency. However, these machines have an important role not only in mass production but also in quality control processes. In this article, we will provide an overview of the injection molding process, especially why laboratory-type injection machines have become indispensable for factories producing with plastics and the advantages of the domestically produced Alarge MINI Plastic Injection Machine in this area. What is Plastic Injection? Plastic injection is the process of melting granular plastic raw material into a mold under high pressure, then cooling and solidifying in the mold to turn it into a final product. This method provides high precision and repeatability. The production cycle consists of three basic stages: Injection: The molten plastic material is injected into the mold cavity. Holding and Cooling: The material is held under pressure while it takes shape. Product Removal: The mold is opened and the product is removed. Why Are Laboratory Type Injection Molding Machines Needed? In factories that manufacture plastics, the physical properties of plastic raw materials to be taken into the production line must be tested meticulously. In these tests, the raw material’s: Moldability Fluidity behavior Dimensional stability after cooling Surface quality such criteria are evaluated. This is where laboratory-type injection machines come into play. With their small-scale production capacity, these devices allow for the production of test samples in a short time. Thus: Quality control of new raw material batches is ensured,R&D processes are supported,Pre-production simulation is performed,Mold design tests are performed. Laboratory-type machines also stand out with their low energy consumption, fast installation, portability and low mold costs. Alarge MINI Plastic Injection Molding Machine: Compact and Effective Solution Alarge MINI Injection is a laboratory type injection machine manufactured in Türkiye. It is ideal for test laboratories and educational use with its small dimensions and functional features. It is also suitable for the production of low-weight (1–10 grams) plastic parts. Technical Specifications: Suitable Materials: PE, PP, PVC, ABS, PET, PC and more Capacity: 2 kg silo capacity Screen: Ease of use with 7” touch screen Control System: PLC + PID temperature control / Motion control with 2 servo motors Temperature: 4-zone temperature control Horizontal Type Structure: Ergonomic and compact design Modes: Fully automatic and semi-automatic operating options Why Should It Be Preferred? Accelerates quality control processes Facilitates low-volume sample production Allows precise testing of molding parameters The behavior of the raw material can be observed before being taken to the production line Provides an ideal solution for educational institutions and R&D centers Conclusion Plastic injection technology is of great importance not only in large production lines but also in laboratory environments. The reliability of the raw material is directly related to the quality of the product. For this reason, laboratory type injection machines are equipment that must be included in the quality control department of every plastic production factory. Local solutions such as Alarge MINI offer high value for quality control laboratories with their accessibility, service support and economic advantages. Source [1] T.C. M.E.
