1.Good sealing performance:
Waterproof and anti-seepage: It can effectively block the entry of moisture, whether it is to prevent rain from seeping into the car, or to resist the erosion of wind and rain on doors and windows, it can keep the room dry.
Dustproof: It can prevent fine particles such as dust and sand from entering the equipment, vehicles or buildings, and keep the internal environment clean. For example, in some industrial equipment, the sealing strip can prevent dust from entering the equipment, reducing equipment wear and failure.
Good airtightness: It can reduce air leakage. For places that need to maintain airtightness, such as aircraft cabins, submarines, high-airtightness laboratories, etc., the role of the sealing strip is crucial. It can ensure the stability of the internal gas and maintain the required air pressure and gas environment.
2.Sound insulation and noise reduction:
Sealing strips can absorb and block the spread of sound and reduce the transmission of noise. In cars, sealing strips can reduce the noise generated by engine operation, tire friction with the road, etc., and provide a quiet driving environment for drivers and passengers; in buildings, sealing strips installed on doors and windows can effectively isolate the noise from the outside world and improve the quietness of the room.

3. Shock absorption and buffering:
When equipment, vehicles or buildings are subjected to vibration or impact, the sealing strip can play a buffering role and reduce the damage to the components caused by vibration. For example, during the driving of a car, the sealing strip can reduce the vibration and collision between the doors, windows and other parts, reduce noise and extend the service life of the parts; on the doors and windows of a building, the sealing strip can alleviate the impact force when closing doors and windows, making the closing of doors and windows more stable.
4. Energy saving and environmental protection:
Through good sealing performance, the sealing strip can reduce the transfer of heat and reduce energy consumption. In buildings, doors and windows with high-quality sealing strips can better insulate and heat, reduce the energy demand for heating in winter and cooling in summer, and achieve energy saving and emission reduction; in cars, the good sealing effect of the sealing strip can reduce the energy consumption of the air conditioner in the car and improve the economy of fuel.
5. Aging resistance and corrosion resistance:
High-quality sealing strips are made of aging-resistant and corrosion-resistant materials, such as EPDM rubber, and have a long service life. Even under harsh environmental conditions, such as high temperature, low temperature, ultraviolet radiation, chemical corrosion, etc., it can maintain good performance and is not prone to aging, deformation, cracking and other problems.

6. Easy installation:
Sealing strips usually have a certain degree of elasticity and flexibility, can adapt to gaps of different shapes and sizes, and the installation process is relatively simple. Whether it is installed on the automobile production line or installed later on the doors and windows of a building, it can be completed quickly and conveniently.
7. Beautiful decoration:
The design of some sealing strips focuses on the aesthetics of the appearance, which can match the overall style of the equipment, vehicle or building and play a decorative role. For example, on some high-end doors and windows, the color and shape of the sealing strips complement the design of the doors and windows, which enhances the overall aesthetics.

Our Advantages
Why us
1.Design advantages:
We conducted a systematic analysis of each parts, and the establishment of a complete parts database. On the basis of this, the paper puts forward the design scheme with excellent using effect, and uses CAD, PRO-E and self-developed rubber product design software to carry on the comprehensive tracking to the mold, sample and mass production. Of the design reached the international professional standards.2.Mold advantages:
We prefer the extremely wear-resistant, imported professional mold material to produce the mold, so that the die life can be greatly extended, thus ensuring the product size consistent. Through the high-precision slow wire machine cutting mold to ensure that the product mold in full compliance with the design and grinding requirements of the small R-angle and small-scale manufacturing excellence in the mold finishing also follow the modern enterprise storage management.3.Process Advantages:
Rubber products manufacturing is a complex process, the process of the complex process, in order to ensure consistency of product quality, adhere to the operation of each process to ensure quality standards, do not care about the cost increase, the enterprise has always uphold the quality of the first concept, strengthen the process control methods and methods to continuously improve product quality and progress.4.Size control:
We use the most advanced size management mode, to ensure that the product size and sample size consistent, this means is a comprehensive, systematic control model, reached the advanced level in developed countries.
