Introduction：
Since 2015, our company has started to support auto manufacturers with rubber parts such as exhaust system hook, mainly supporting auto manufacturers such as saic, baic, chery and byd. Have the ability to develop and design synchronously with customers.
Our hooks are mainly divided into pure rubber hooks and rubber and skeleton hooks. The main materials used are silicone and EPDM rubber.
Classification:
1.Pure rubber Hook: generally used in passenger cars and vehicles with smaller exhaust system.
2.Hook with skeleton and rubber combination: it is generally used for SUV or MPV and other large vehicles. The exhaust system is of relatively high quality and the Hook strength is required.
Material Selection Principle of Rubber:
Main performance parameters: static stiffness, dynamic stiffness, durability and high temperature resistance.
Main materials: VMQ, EPDM.
1.Features of VMQ:
● It has a good high temperature resistance, working temperature range of -60℃~250℃;
● Silicone hook compared to EPDM, high temperature resistance is more excellent;
● Silicone hook generally arranged in the hot end of the body parts.
2.Features of EPDM:
● It has good damping property and metal bonding property;
● Operating temperature can reach -40℃~150℃;
● EPDM rubber hook are generally arranged in the middle and back of the cold end of the body.
Quality Control Method
● Test and Record for Each Batch of Compound
● Each Shift Product Dimensions, Hardness, Stiffness Test
● Quarterly Product Durability Testing
● Rubber Physical Property Test Every Quarter
● 100% Inspection for Dimension,Appearance,Hardness before Delive
