With the development of electric vehicles (EVs), the advancement of automobile industry technology, and the enhancement of people’s awareness of environmental protection, electric vehicles are becoming more and more popular.

At present, the materials used in the manufacture of automotive fluid pipelines can be divided into three types, metal, rubber, and nylon plastic.

The electric cooling system of EVs is particularly critical, liquid cooling is currently the main way for EVs cooling. As an important part of EVs, coolant fluid pipelines need to meet multiple requirements such as hydrolysis resistance, high temperature resistance, and lightweight.

In recent years, Thermoplastic Vulcanizate (TPV) has the characteristics of both rubber and plastic, and its application in fluid pipelines of EVs has become more and more extensive.

DEKUMA launched TPV Knitted Composite Hose Extrusion Line for EVs, which adopts the combination of TPV (inner layer) + knitted layer (polyester, aramid) + TPV (coating layer), which can simultaneously provide three product structures production solution of TPV knitted composite hose, TPV double-layer composite hose and TPV single-layer hose.

In full use of TPV material light weight, simple process, easy connecting, shockproof characteristics, while using the intermediate fiber knitted reinforcement layer to increase the compressive strength of the hose, improve the safety factor.

TPV can better combine the material characteristics of plastic and rubber, and has alternative advantages in the application of cooling pipeline of EVs in the future.

DEKUMA TPV Knitted Composite Hose Extrusion Line, the inner TPV hose body is accurately extruded by the inner TPV extrusion system, through customized knitted coating fiber reinforced layer, and then through the infrared heating system to make the knitted layer and the inner and outer layer materials perfectly bonded, forming a complete TPV knitted composite hose.

The acceptance samples have been tested and approved by a number of testing institutions in China and Overseas, and the products fully meet the requirements of EVs fluid management.

After nearly three years of development, the application of new materials has gradually extended from “hard” power to “soft” power.

DEKUMA self-developed the TPV Knitted Composite Hose Extrusion Line, which has accelerated the application process of new materials and new fields, and solved the core production problem of “bottleneck” in the development of the auto parts industry.

DEKUMA TPV Knitted Composite Hose Extrusion Line not only realizes the breakthrough in the supply of new materials for EVs, but also further realizes the foresight development of China made equipment, forming a new generation of products and a new line of industry leadership status.

In future, with the increasing application cases of new materials to pipelines, through the continuous exploration of different structure performance, DEKUMA will bring a new boost to the development and iteration of EVs fluid pipeline!

Decryption of DEKUMA’s “Outside Mold Decoration Technology”

 

With the continuous development,OMD technology has been deeply concerned and sought after by various industries for its unique product appearance decoration effect .

OMD technology can achieve decorative effects of various metals, simulation materials, complex curved surface locating patterns, light transmission, skin feeling, etc. It is widely used in automobile, household appliances, electronic 3C and other fields, and will gradually replace the traditional non-environmentally friendly surface treatment technologies in the future to produce richer decorative effects on the surface.

To fill the domestic technical vacancy and continuously achieve breakthroughs in the new technical field, DEKUMA has launched a new DOD (differential pressure overlay decoration) technology scheme through independent research and development and years of project practice, which s Solve the problem of China’s dependence on imported equipment and imported film materials, with the aim to provide customers with complete equipment-film-production solutions, so as to realize the localization.

 

01 Introduction of OMD process

 

DOD (Differential Pressure Overlay Decoration) is a new technology scheme of OMD (Out Mold Decoration) lauched by DEKUMA as well as an extension of IMD (In-Mold Decoration).

OMD uses heating, vacuum and high-pressure gas to realize product surface overlaying or transfer printing, and can realize 3D surface decoration process with higher quality appearance effect, and belongs to three-dimensional appearance decoration technology.

As an extension of IMD process, it combines texture effects such as color and texture, and perfectly combines printing technology, texture and metallization characteristics, so that it can make more three-dimensional and highly 3D curved surface products and achieve many appearance effects, including metal wire drawing, wood grain, stone grain, leather and etc.

 

02 Process characteristics of OMD

 

OMD process can be used to decorate the surfaces of various materials: plastic, glass, metal, wood, stone, etc., because the softening temperature of the film in the manufacturing process is lower than that of the in-mold decoration, and then the touch will be better preserved, and it will not be easily weakened or disappear. The touch has obvious concave-convex feeling, which can solve the overlaying problem and yield of complex products that cannot be handled by manpower.

 

03 Introduction of OMD process flow

 

OMD equipment process is a process where the vacuum and atmospheric pressure are used to make the film with adhesive layer heated and overlaid on the surface of the product and tightly attached.

The key point of manufacturing lies in the utilization of pressure difference. Through locating, evacuating, film heating, pressurizing and other operations, the mold can be opened and the product can be taken out after six steps.

 

04 Advantages of OMD process

 

● Fast and low-cost proofing. The surface overlaying process can be done just by placing and fixing the products, thus there is no need to open the mold and then process it like IMD;
● Good applicability and convenience. It can simultaneously put a variety of products with different shapes in the forming bin for product overlaying;
● The process is green and environmentally friendly, without considering the environmental impact assessment, and it is one of the best choices to replace the  painting, water transfer printing and electroplating;
● Large design freedom. It can be applied to various complex shapes for deeper processing. During the processing, it can be overlaid to the reverse hook part and the end of the product to meet the surface decoration requirement of complex shapes;
● Wide application. OMD process not only plays a role in decorating the appearance of products, but also improves the performance of products, which greatly stimulates the sensory needs of consumers. At present, it is mainly used in the automobiles, electronic 3C, medical treatment, sports equipment and household appliances, and has a broad market prospects.

 

05 Development of DEKUMA in OMD process

Owing to the continuous investment of DEKUMA in research and development of process technology, optimization of product design scheme and improvement of process level, DOD (differential pressure overlay decoration) technology has been highly recognized by the market.
It has already obtained a number of invention and utility model patents and national software copyrights in China and Hong Kong and also has successfully broken through the problem of relying on imported equipment and imported membrane materials in China, and it can provide customers with complete solutions of equipment-membrane materials-production.
Compared with the imported equipment, DOD (differential pressure overlay decoration) technology scheme is very competitive in terms of the quality, service and price. Advanced equipment technology, through the adjustment and coordination of technical parameters, can reduce the requirements for diaphragms, so that the most domestic diaphragms can be popularized and widely utilized. The supporting development of automatic production equipment and information collection and analysis system makes customers more efficient in production and worry-free in management.
The new breakthrough of DOD (differential pressure overlay decoration) technology scheme benefits from the rich foundation laid by technological progress and innovation. In the future, DEKUMA will strive to build a solid basis for “replacing the imports and the labors” with scientific and technological innovation and ingenuity, provide customers and consumers with more high-quality domestic products, and help the high-quality development of China’s manufacturing industry.
