Choosing the Perfect Injection Molding System for Small Plastic Parts in 2024
What Is a Small Injection Molding Machine?
Small injection molding machines are also called small plastic parts injection molding machines. It is an injection molding machine specially developed for small businesses. Unlike large injection molding machines, small injection molding machines are designed for lower volume, prototyping, and small-scale manufacturing operations.
They offer advantages such as space efficiency, low initial investment costs and ease of operation, making them suitable for small businesses, start-ups and educational institutions. These machines typically have lower clamping forces and injection capabilities than larger machines, but are still able to produce high-quality plastic parts with precision and consistency.
How Does the Small Plastic Parts Molding Machine Work?
The working principle of the injection molding machine is to use the thermophysical properties of plastic to add the material from the hopper to the barrel, and the outside of the barrel is heated by a heating ring to melt the material.
The barrel is equipped with a screw that is driven and rotated by an external power motor. Under the action of the screw, the material is transported forward along the screw groove and compacted. The material is gradually plasticized and melted under the dual effects of external heating and screw shearing. and homogenization.
When the screw rotates, the material pushes the molten material to the head of the screw under the action of friction and shear force of the screw groove. At the same time, the screw retreats under the reaction of the material, causing the screw head to form a storage material. space to complete the plasticization process.
Then, under the action of the piston thrust of the injection cylinder, the screw injects the molten material in the storage chamber into the mold cavity through the nozzle at high speed and high pressure. The molten material in the cavity is pressure maintained, cooled, solidified and shaped. , the mold opens the mold under the action of the mold closing mechanism, and the shaped product is ejected and dropped from the mold through the ejection device.
What Is the Main Use of Small Injection Molding Machines?
Small injection molding machines are mainly used in parts production in industrial manufacturing, school education, small businesses, home use, small shops and home stores.
Medical Devices: Used in the manufacture of medical device components such as syringes, surgical instruments and diagnostic equipment.
Consumer Goods: Used in the production of consumer goods such as toys, appliances, and electronics.
Automotive Industry: Plastic parts for automotive interiors, exterior components and under-the-hood applications.
Electronics: They are used in the production of plastic housings, connectors and other components for electronic devices.
Packaging Industry: Small injection molding machines produce plastic packaging components such as lids, closures, containers and bottles.
Industrial Parts: Plastic parts used in a variety of industrial equipment, machinery and tools.
Others: cups, containers, toys, pipe fittings, electrical components, telephone receivers, bottle caps, auto parts.
How Many Types of Small Injection Molding Machines Are There?
Injection molding machines are classified by the main types of drive systems they use: hydraulic, electric, or hybrid.
Hydraulic injection molding machine: The hydraulic injection molding machine uses an oil pump as the power source of the injection molding machine, and uses various valves to control the oil pressure and flow to meet various requirements of the injection molding process.
All-electric injection molding machine: The all-electric injection molding machine uses servo motors and screw rods to realize the injection molding action. It has the advantages of stable injection, energy saving and cost reduction, efficient control, and environmental optimization. However, due to the limitations of the servo motor, the clamping force is limited, and it is more suitable for making small plastic products.
Hybrid injection molding machine: The hybrid injection molding machine adopts a servo motor hydraulic pump drive system for the action units such as mold opening and closing, ejection, and neutron. The injection and material storage are directly driven by the servo motor. While retaining the high clamping force of hydraulic clamping, it achieves high response, low noise and more precise speed positioning and pressure control of the entire motor.
How to Choose the Best Small Injection Molding Machine?
Generally speaking, enterprise or department managers and relevant technical personnel who have been engaged in the plastic products industry for many years have experience in using injection molding machines, so they have the ability to make their own judgments and select appropriate injection molding machines for purchase.
However, many enterprise or department managers may not know much about small injection molding machines, or do not have professional technicians to provide reference. Therefore, they need the assistance of injection molding machine manufacturers to decide which type, model, and parameters of small injection molding machines to use. , or even the customer may only have samples or ideas of plastic products, and then directly ask the injection molding machine manufacturer whether the machine can produce it, or directly ask which model is more suitable.
The following is relevant information compiled by SUNBUN for your reference.
The factors that determine the type, specification, and brand of a small injection molding machine mainly include molds, products, plastics, molding requirements, etc. Therefore, you must know the following information before making a choice:
1. Mold size (width, height, thickness), weight, special design, etc. required for plastic products;
2. Type and quantity of plastic used in plastic products (single raw material or multiple plastics);
3. Appearance dimensions (length, width, height, thickness), weight, etc. of injection molded products;
4. Molding requirements for plastic products, such as quality conditions, production speed, etc.
How Much Does a Small Injection Molding Machine Cost?
Once you want to buy a cheap small injection molding machine from the local market or overseas, you may wonder how to get a reasonable price? According to Alibaba, ebay, and Made-in-China, the average cost of purchasing a new small injection molding machine in 2023 will be approximately $22,800.00. The cheapest small hydraulic injection molding machine in 2024 starts at $18,500.00.
If you want to buy overseas, taxes, customs clearance and shipping should be included in the final price.
