As a leader in innovative and efficient molding solutions, YIZUMI stands out in the industry, offering state-of-the-art injection machines that cater to a wide range of applications. This article explores the fundamentals of injection machines, their benefits, and why YIZUMI is the go-to choice for manufacturers.

How does an injection machine work?

An injection machine, also known as an injection molding machine, is a device used to manufacture plastic parts by injecting molten material into a mold. The process involves several key steps.

1. Material Feeding - Plastic granules, stored in a hopper, are fed into the injection molding machine. The hopper releases a controlled amount of material into the barrel of the machine to begin the process.

2. Melting - Inside the barrel, the plastic granules are heated using heating bands and the frictional heat generated by the rotating screw. The temperature inside the barrel is carefully controlled to melt the plastic uniformly without degradation. As the screw turns, it conveys the molten plastic forward towards the mold.

3. Injection - Once the plastic reaches the molten state and the desired amount is accumulated, the injection process begins. The screw continues to rotate, pushing the molten plastic through a nozzle into the mold cavity. Injection occurs at high pressure to ensure the plastic fills the mold completely and accurately replicates the mold's geometry.

4. Cooling - As soon as the mold cavity is filled with molten plastic, the cooling phase begins. Cooling channels within the mold facilitate the rapid transfer of heat from the molten plastic to the mold steel. This rapid cooling solidifies the plastic into the shape defined by the mold cavity. The cooling process is critical for achieving the desired part quality and cycle time efficiency.

5. Ejection - Once the plastic has sufficiently cooled and solidified, the mold opens. The ejection mechanism, typically a system of pins or ejector plates, pushes the finished part out of the mold cavity. The mold then closes again, ready for the next injection cycle.

Each step in the injection molding process plays a crucial role in ensuring the quality, consistency, and efficiency of manufacturing plastic parts. From material feeding to ejection, precise control and optimization are essential to meet the demands of various industries and applications.

What are the different types of injection machines?

Injection machines come in various types, each suited to specific applications and requirements.

Hydraulic Injection Machines

Hydraulic injection molding machines utilize hydraulic systems to power the injection process. These machines are known for their robustness and capability to handle large-scale production with high force requirements.

Electric Injection Machines

Electric injection molding machines are driven by electric motors rather than hydraulic systems. They offer superior energy efficiency, precise control over injection speeds and pressures, and reduced maintenance requirements compared to hydraulic machines. YIZUMI's FF Series Electric Injection Molding Machine?exemplify this technology, providing exceptional accuracy and repeatability. They are ideal for high-precision molding of thin-wall parts, medical components, and consumer electronics where precision and cleanliness are paramount.

Hybrid Injection Machines:

Hybrid injection molding machines combine hydraulic and electric systems to leverage the strengths of both technologies. These machines use electric servo motors for injection and hydraulic power for core functions such as mold closing and ejection.

Servo-Hydraulic Injection Machines:

Servo-hydraulic injection molding machines integrate servo motors with hydraulic systems to enhance energy efficiency and control. By using servo-driven hydraulic pumps, these machines adjust power consumption based on actual demand during the injection process, reducing energy wastage and operational costs.

Multi-Component Injection Machines:

Multi-component injection molding machines enable the simultaneous injection of multiple materials or colors into a single mold. This capability is essential for producing complex parts with varying material properties or for over-molding processes where different materials are bonded together. YIZUMI's CE-P Series High-end Electric Multi-component Injection Molding Machines are engineered for flexibility and precision. They support advanced molding techniques such as co-injection and sequential injection, allowing manufacturers to produce sophisticated parts for automotive interiors, electronics, and medical devices efficiently, ideal for auto parts, medical, and 3C electronics, offers advanced technology and efficiency. With refined control, quiet operation, and energy efficiency, it maintains YIZUMI's versatility and reliability.
