Comparing Different Types of Plastic Injection Moulding Machines: Pros and Cons

Plastic injection moulding is a versatile manufacturing process widely used in various industries such as machinery, automobile, electronics, and electrical. The choice of the right injection moulding machine plays a crucial role in achieving high-quality, cost-effective production. In this article, we will delve into the pros and cons of different types of Plastic Injection Moulding Machine, with a focus on the sliding table injection machine.

Understanding Plastic Injection Moulding Machines

Plastic injection moulding machines come in various types, each designed for specific applications. The common types include hydraulic, electric, and hybrid machines. Each type has its own set of advantages and disadvantages, influencing their suitability for different manufacturing needs.

Hydraulic Injection Moulding Machines


  • Cost-Effective: Hydraulic machines are generally more affordable than their electric counterparts.
  • High Clamping Force: These machines can provide high clamping forces, making them suitable for molding large and complex parts.
  • Low Maintenance: Hydraulic machines are known for their simplicity, resulting in lower maintenance costs.


  • Energy Inefficiency: Hydraulic machines consume more energy compared to electric ones, leading to higher operational costs.
  • Limited Precision: They may have limitations in precision and accuracy, affecting the quality of intricate parts.

Electric Injection Moulding Machines


  • Energy Efficiency: Electric machines are more energy-efficient, resulting in lower operating costs over time.
  • High Precision: These machines offer precise control, making them ideal for intricate and small parts.
  • Cleaner Operation: Electric machines produce less noise and have a cleaner operation, contributing to a better working environment.


  • Higher Initial Cost: Electric machines tend to have a higher upfront cost, which may be a deterrent for some businesses.
  • Limited Clamping Force: They may have limitations in providing high clamping forces for larger parts.

Hybrid Injection Moulding Machines


  • Energy Efficiency: Hybrid machines combine the energy efficiency of electric machines with the high clamping force of hydraulic ones.
  • Versatility: They offer versatility in terms of applications, making them suitable for a wide range of manufacturing needs.
  • Lower Noise Levels: Hybrid machines produce less noise compared to traditional hydraulic machines.


  • Complexity: Hybrid machines can be more complex than purely hydraulic or electric machines, potentially leading to higher maintenance costs.
  • Moderate Initial Cost: While not as expensive as electric machines, hybrids still have a moderate upfront cost.

Sliding Table Injection Machine for Specialized Applications

In addition to the common types mentioned above, there are specialized machines like the sliding table injection machine. This type of machine is particularly suitable for industries such as machinery, automobile, electronics, and electrical.

Pros of Sliding Table Injection Machine:

  • Enhanced Precision: The sliding table design allows for precise and repeatable movements, ensuring high precision in molding.
  • Efficient Production of Complex Parts: It excels in efficiently producing complex parts with varying geometries.
  • Improved Access: The sliding table provides better access to the mold, simplifying the setup and maintenance processes.

Cons of Sliding Table Injection Machine:

  • Specific Applications: While highly effective for certain applications, the sliding table design may not be suitable for all types of plastic molding.


Choosing the right Plastic Injection Moulding Machine involves weighing the pros and cons of each type based on the specific requirements of the manufacturing process. The sliding table injection machine, with its focus on precision and efficiency, proves to be a valuable choice for industries like machinery, automobile, electronics, and electrical. As technology continues to advance, manufacturers must carefully evaluate their production needs to make informed decisions that lead to optimal outcomes in terms of cost, quality, and efficiency.
