Injection Molding Machines Advantage
Traditional injection molding machines require different drying times before raw materials are put into production. The exhaust type injection molding machine eliminates the need for a separate device outside the injection molding machine to perform a separate drying operation, integrates the input of raw materials into the output of the product, and reduces the number of production operations, making the production of plastic products more efficient and convenient. At the same time, the vented injection molding machine eliminates the need for separate drying outside the machine, eliminating the potential safety hazards associated with the original drying process, and eliminating the potential risk of fire due to improper operation in the drying process. Safety is further guaranteed. At the same time, the volatile gas generated during the melting process of the raw material is discharged. In addition, the exhaust injection molding machine also further implements the new development requirements of energy saving and high efficiency.

Disadvantage Of Traditional Hydraulic Injection Molding Machine
The drying process requires a lot of power consumption, which is inconsistent with my country's national policy of energy conservation and environmental protection.
The raw materials of drying plastic products need to be equipped with relevant auxiliary machines for drying, and most of the auxiliary machines are expensive, which compresses the profit space.
The drying process will generate a large amount of dust, which will cause dust pollution in the workshop, and also affect the surrounding environment of the factory, which also threatens the health of workers in the workshop.
The traditional production mode has great security risks. In the process of drying raw materials, if the heat generated cannot be dissipated into the air in time, or the air circulation is poor, and the drying time is too long, it is very easy to cause fire and bring irreversible losses to the manufacturer.
The drying process of raw materials requires precise manual control. If the drying time is too short, traces will be left on the surface of the product (called "splashes" in the industry), and if the drying time is too long, the produced products will turn yellow and discolor, reducing product quality and appearance.
Drying requires a lot of time investment, which increases the production time of the product and the production cycle. affect production efficiency. If a holiday ends, and workers start to bake materials during the working day, the production of products can only be carried out in the second half of the working day, which will wasted workers' working hours and reduce production efficiency.

Common Question In Injection Molding Machine
The working principle of an injection moulding machine involves several steps. First, plastic pellets or granules are fed into a hopper. The material is then heated and melted in a barrel using a rotating screw or a plunger. Once the plastic is in a molten state, it is injected into a mould cavity under high pressure. The plastic cools and solidifies inside the mould, and then the mould opens, allowing the finished part to be ejected.
Safety is paramount when operating an injection moulding machine. Some important safety precautions include:
- Operator Training: Ensure that operators are properly trained in the operation of the machine, including safety procedures and emergency protocols.
- Personal Protective Equipment (PPE): Operators should wear appropriate PPE, including safety glasses, gloves, and protective clothing.
- Machine Guarding: Install safety guards and interlocks to prevent access to moving parts during the machine's operation.
- Lockout/Tagout (LOTO): Follow lockout/tagout procedures to safely isolate the machine from power sources during maintenance or repair.
- Ventilation: Provide adequate ventilation to remove fumes or vapors generated during the melting and moulding process.
The frequency of servicing an injection moulding machine depends on factors such as the machine's usage, operating conditions, and manufacturer recommendations. Regular maintenance and inspections are typically performed at scheduled intervals, which can range from daily checks for critical components to monthly or yearly maintenance tasks. It's important to follow the manufacturer's guidelines and keep a maintenance log to ensure the machine's optimal performance.
Injection moulding machines can encounter various troubleshooting issues, including:
- Injection Problems: These include issues with material flow, such as short shots, flash, or sink marks, which may be caused by incorrect temperature, pressure, or injection speed settings.
- Moulding Defects: Defects like warping, voids, or surface imperfections can occur due to mould design issues, incorrect material selection, or inadequate cooling.
- Machine Malfunctions: Mechanical or electrical problems, such as hydraulic leaks, sensor failures, or control system errors, can affect the machine's performance.
- Temperature Control: Inaccurate temperature control can lead to inconsistent part quality or processing difficulties.
- Hydraulic System Issues: Problems with the hydraulic system, such as low oil level or contaminated oil, can impact the machine's operation.
The typical lifespan of an injection moulding machine can vary depending on several factors, including the machine's quality, usage, maintenance, and technological advancements. Generally, a well-maintained machine can last for 10 to 20 years or more. However, it's important to consider factors such as wear and tear of critical components, availability of spare parts, and advancements in technology that may render older machines less efficient or cost-effective.
