Modern car’s front and rear
bumpers adopt plastic as raw material, not only can keep the function of
protection, but also has with the harmony and unity of the body shape,
lightweight, reduce fuel consumption, etc.Sino auto bumper mould
Bumper plastic choice,must satisfy the several aspects like a good use of performance requirements, process performance requirements and reasonable cost requirements.When choosing modified PP materials, shall meet the following four basic characteristics:
First, good heat resistance, then this range (80-100 ℃)
Second, the impact strength should be controlled in （0.3-4）J*cm²
Third, the scope of the tensile strength by 29 Mpa
Fourth, good formability and weather resistance.
Chinese mould made by sino-Bumper thickness range is generally (3 +) 0.25
mm - (3.5 + 0.25) mm. The design, with enough variation in thickness transition
zone to avoid impact parts surface quality of the thickness of the change of purpose.Ejection
Angle should be greater than zero.Car front bumper is a safety device, capable
of absorbing and buffer the impact to protect the front car body.The bumper is
a safe, and decoration, its structure design is closely related to the vehicle
safety, not only the vehicle quality perception.
