About us
These years, We are working on various project of customers and long term working in rubber industry. We have faith in giving your professional advice on your particular project.
At present, our market have been expanded to more than 30 countries, and still growing.
First we will get drawing or sample from our client to check their design. If there is no drawing or sample, we will ask some question about product concept and design idea.
Then according to what application environment of rubber part, we will help design drawing and what raw material is best for rubber part. OEM parts are ok for us.
 We can meet your requirement of the design and use for different shapes and material,
 And high/low temperature, foam/sponge or solid rubber profile, fire resistance and special property of any rubber profile and molding rubber part
The advantage of the company
1.We have excellent complete production line with advanced production and test equipment
 Adding First-class technicians, so that we can  offer you the competitive price and high quality ,fast delivery time .
2.We have a special drawing design department to design the correct drawing data meeting your requirements. Then, we will use CAD or other format drawing to carry on tracking the production of tooling, sample ,mass goods. To avoid something wrong to each process. To make sure all of dimension are correct.
3.We also has special production supervision department. The engineer staff will Supervise  each process from the manufacture of tooling to the production of mass goods.
Reduce something wrong happened, finally offer you parts meeting your technology requirement.
4. All of Raw material are past quality certification,In the meantime, we will first delivery test report of rubber part when all of mass goods are finished. And make sure the quality meet your requirement, then make shipment

The different material of rubber sealing strip will cause different property.
EPDM/NBR/silicone/SBR/PP/PVC etc.

Item	EPDM	NR	silicone	PVC
Hardness (Sha)	30~85	30~90	20~85	50~95
Tensile strength (Mpa)	≥8.5MPa	> 20 Mpa	3~8	10~50
Elongation(%)	200~550	1000%	200~800	200~600
Specific Gravity	0.75-1.6	1.15-1.21	1.25~1.35	1.3~1.7
Temperature range	-40~+120°C	-50~70ºC.	-55~+350°C	-29°C - 65.

1. the property of NR
 It has good wear resistance, high elasticity, breaking strength and elongation, But in the air, it is easy to get age, and it is get sticky when it get in touch with heat, which is easy to expand and dissolve in mineral oil or gasoline, but it is resistant to strong acid, but not to Alkali . working temperature is -50~70ºC.
2. the property of EPDM
Weather ability, aging resistance, ozone resistance, chemical stability are excellent, and CFCS and a variety of refrigerants. Working temperature is -50~150
3. the property of silicone
It has excellent heat resistance, cold resistance, ozone resistance and atmospheric aging resistant.Good electrical insulation performance,The tensile strength and wear resistance are generally poor and has non- oil resistant. The working temperature is -55~250ºC
4. The property of NBR
Good oil resistance, heat resistance, abrasion resistance, solvent resistance and high - pressure oil,But it is not suitable for polar solvents, such as ketones, ozone, nitro-hydrocarbons, and chloroform. The working temperature is -40~120 ºC
5. the property of CR
It has good elasticity, wear resistance and atmospheric aging resistance. It is not afraid of violent distortion and flammability.Chemical stability. The working temperature is -40~100 ºC
6. The property of FKM
Excellent high temperature resistance,And have excellent chemical resistance, most oil and solvent (other than ketones and esters).cold resistance is not good.

• Answer:We didn't set the minimum order quantity,1~10pcs some client has ordered.
• If we can get sample of rubber product from you?
•  Answer:Of course, you can. Feel free to contact me about it if you need it.
• Do we need to charge for customizing our own products? And if it is necessary to make tooling?
• Answer: if we have the same or similar rubber part, at the same time, you satisfy it.
   Well, you don't need to open tooling
  New rubber part, you will charge tooling according to the cost of tooling.
  In additional,if the cost of tooling is more than 1000 USD, we will return all of them to you in the future when purchasing order quantity reach certain quantity our company rule
• How long you will get sample of rubber part?
• Answer: Usually it is up to complexity degree of rubber part. Usually it take 7 to 10work days.
• How many your company product rubber parts?
•  Answer:It is up to the size of tooling and the quantity of cavity of tooling. If rubber part is more complicate and much bigger, well maybe just make few, but if rubber part is small and simple, the quantity is more than 200,000pcs.
• Silicone part meet environment standard?
• Answer:Our silicone part are all high grade 100% pure silicone material. We can offer you certification ROHS and SGS, FDA .Many of our products are exported to European and American countries. Such as: Straw, rubber diaphragm, food mechanical rubber, etc.
