150m/min! Dekuma Sets New Record for Microduct Extrusion Speed

 

Recently, the high-speed testing of the DEKUMA microduct production line has achieved a complete success, achieving the expected goal of a stable production speed of 150 m/min.
This microduct production line test was a comprehensive demonstration carried out in conjunction with European customers visiting the factory for inspection. The configuration of the production line was upgraded in multiple directions according to customer needs. The original production line had achieved a stable production speed of 80-100 m/min.
Through cooperation with customers, DEKUMA deeply understands that the rapid development of global communication technology in recent years has driven the explosive growth of demand for fiber optic networks. Therefore, customers’ requirements for the production efficiency of microducts are increasing.
In order to meet customers’ urgent needs for high output and reduced labor costs, DEKUMA has optimized the original microduct production line.
After continuous testing and adjustment, the DEKUMA technical team has finally achieved a significant increase in production efficiency in recent months, raising the target speed of the production line to over 150 m/min. The newly designed automatic double station winder also passed the test smoothly.
After a series of technical research, DEKUMA launched the microduct production line in 2011. The product has been continuously iterated and upgraded, creating three major advantages for users:

1, Optimize production processes and increase production capacity.

The highest production speed of this line when producing 14mm microtubes can reach 100m/min.

During the entire line test process, the highest production speed of 7mm microtubes reached the expected goal of 150m/min, and the real-time detection of various product indicators met the requirements of the European customers who visited the site.

 

2, Automated configuration and efficient winding.

The entire line integrates automated control and is equipped with a dual-position automatic rewinder, greatly improving the degree of automation.

 

3, Provide a complete set of production solutions to save time and effort.

DEKUMA provides users with a complete turnkey solution, with production line plans for all specifications of microducts and various structural bundle tubes.

 

DEKUMA insists on survival through quality and development through innovation, providing users with better products and services.

The technology of DEKUMA’s microduct production line has reached the leading level in the industry and can meet users’ requirements for high output, high speed, and high efficiency equipment.

At the same time, automated control realizes convenient operation of equipment, reduces dependence on manual labor, and provides a one-stop service for users with a complete set of production solutions, making it the first choice for project investment and equipment upgrades for domestic and foreign customers.

Dekuma’s solution to composite insulator production issues

 

With the emergence of polymer materials, ceramics and glass are no longer the preferred insulation materials. European and American countries have started to research polymer insulators, studying the physical and electrical properties, long-term reliability, and optimal shapes of electric insulators, leading to continuous improvement in productivity.

 

Among the polymer materials that can replace ceramics and glass, silicone rubber has more advantages than other polymers. Composite insulators, which are made of silicone rubber, are used as insulators for power lines and are mainly used in substations.

Dekuma not only has many years of experience in independently researching and developing machines, but also has an experienced team that understands the product manufacturing process. This special machine, which was developed by our over 25 years of experience engineering and technical team and adheres to German manufacturing standards for insulator production, is highly recognized by customers in the niche market due to its high efficiency, stability, and wide applicability.

“Composite insulator rubber machine”

production of finished products

 

What exactly makes the performance of this special machine for composite insulators so powerful?

 

1、Low-platform designed for easy operation

 

The low-platform design provides comfortable operating height, facilitates equipment operation and layout, and eliminates the need for foundation pits. The fully automatic injection system eliminates tedious steps such as material weighing and filling, reducing labor intensity. The professional design of the cold runner system saves materials and improves production efficiency.

 

 

2、Stability and durability

 

The bolster is thick, with good anti-deformation performance and durability, resulting in small burrs on the produced items. Equipped with imported electrical and hydraulic components, enhances the stability and reliability.

 

 

3、Multi-purpose machine with wide range of applications

 

Developed specifically for insulators, it can cover all specifications from 10kV to 550kV, and is a multi-purpose machine with a wide range of applications.

 

 

Dekuma has always focused on “technological innovation” as its development direction, continuously deepening its presence in niche markets, and improving its brand influence and industry competitiveness.

 

At the same time, Dechom will continue to strengthen communication and cooperation with users, deeply understand their needs, improve user satisfaction and trust, and provide users with higher quality, intelligent, and environmentally friendly products and services, making greater contributions to the development of the insulator industry.
