Injection molding is a widely used manufacturing process in which molten plastic is injected into a mold cavity to produce a wide variety of products, from small electronic components to large automotive parts.

Injection molding machines are the key equipment in this process and are available in different types, including hydraulic, electric, and hybrid machines.

Servo-Hydraulic Injection Molding Machine

 

A servo-hydraulic injection molding machine is a hybrid machine that combines the advantages of both hydraulic and electric machines. It uses a servo motor to drive the hydraulic pump, allowing for more precise and efficient control of the machine's movement.

 

Here are some of the advantages of using a servo-hydraulic injection molding machine:

 

Improved Product Quality

 

Servo-hydraulic machines can improve product quality by producing more consistent and accurate parts. This is especially important for products that require tight tolerances or have complex geometries.

 

Precision and Accuracy

 

Servo-hydraulic machines are more precise and accurate than traditional hydraulic machines. The servo motor allows for more precise control of the machine's movement, resulting in more consistent and accurate parts.

 

Faster Cycle Times

 

Servo-hydraulic machines can achieve faster cycle times than traditional hydraulic machines. This is due to the fast response time of the servo motor, which allows for quicker injection and clamp movements.

 

Reduced Noise Levels

 

Servo-hydraulic machines are generally quieter than traditional hydraulic machines. This is because the servo motor operates at a lower RPM and produces less noise.

 

Longer Machine Life

 

Servo-hydraulic machines have a longer machine life than traditional hydraulic machines. The precise control of the machine's movement reduces wear and tear on the machine's components, resulting in longer machine life.

 

Energy Efficiency

 

One of the biggest advantages of using a servo-hydraulic injection molding machine is its energy efficiency. Compared to traditional hydraulic machines, servo-hydraulic machines can save up to 60% of energy consumption, resulting in significant cost savings.

 

Reduced Maintenance Costs

 

Servo-hydraulic machines require less maintenance than traditional hydraulic machines. The precise control of the machine's movement reduces the need for regular maintenance, resulting in reduced maintenance costs.

 

What Industries Are Servo-Hydraulic Machines Commonly Used In?

 

Servo-hydraulic machines are commonly used in industries such as automotive, medical, electronics, and consumer goods.

They are suitable for producing a wide range of products, from small precision parts to large structural components.

 

Can Servo-Hydraulic Machines Be Used for All Types of Plastics?

 

Servo-hydraulic machines can be used for all types of plastics, including thermoplastics and thermosetting plastics. The key is to select the appropriate machine size and configuration for the specific material being used.

 

Are Servo-Hydraulic Machines More Expensive Than Traditional Hydraulic Machines?

 

Servo-hydraulic machines tend to be more expensive than traditional hydraulic machines.

However, the cost savings from improved energy efficiency and reduced maintenance costs can make up for the higher initial investment over time.

In a word, servo-hydraulic injection molding machines offer significant advantages over traditional hydraulic machines. These machines are more energy-efficient, precise, and accurate, with faster cycle times and reduced noise levels.

They also have a longer machine life and reduced maintenance costs, while improving product quality. If you are looking to invest in an injection molding machine, a servo-hydraulic machine is definitely worth considering.
