Applied
 to automobile engine cooling water assisted injection molding method, 
can realize one-piece processing, can achieve the expected one-time 
structure, greatly shorten the processing cycle, reduce cost and improve
 the quality of the product and quality than traditional steel pipes to 
reduce about 50% of the weight and the clamp and the tube body is in the
 process of a plastic injection produced at the same time, without 
antirust processing, low cycle time and stable quality
●Used in VW EA888 and EA211 engine cooling water pipes.
●Weight reduction 75%, saving 40% cost, recyclable materials.
●Lighter engine parts can reduce fuel consumption.
