CRG works extensively with automotive OEM’s and Tier 1-3 suppliers for the provision of non-marking automotive rubber bumpers. If non-marking is not a project requirement, CRG also has the capability to supply these types of profiles from the wide range of materials that we carry.
What are non-marking automotive rubber bumpers?
Rubber bumpers are used to protect bodywork, doors, and other finished surfaces on vehicles from damage. Rubber bumpers are also used as feet and stops; for example, rubber bumpers can restrict the range of motion of movable vehicle parts, such as trunk lids, seating, etc. For these types of applications, rubber bumpers are used to prevent metal-to-metal or surface-to-surface contact.
Rubber bumpers can be raised or recessed from the surface onto which they are mounted. They may be self-anchoring or secured to their mounting surface with a screw or rivet. For extra durability, some rubber bumpers are produced with a steel support bushing.
Non-marking automotive rubber bumpers are usually produced from materials which will not leave behind a mark when the bumper contacts or rubs against another surface. In contrast, bumpers produced from traditional rubbers, such as Natural Rubber, will tend to leave a mark should the bumper come into contact with another surface.
What types of materials are used to produce non-marking automotive rubber bumpers?
CRG produces rubber bumpers from a range of elastomeric materials. Depending upon the specific application, automotive grade rubbers such as EPDM are often used, while TPE (Thermoplastic Elastomers) such as Santoprene™ are sometimes employed for more demanding applications. TPE materials combine the best properties of rubber and thermoplastics. They offer advantages over standard grade rubbers by offering greater resistance to chemical attack and weathering from exposure to UV and ozone. In applications where a rubber bumper is likely to come into contact with aggressive automotive fluids and high temperatures, the use of advanced elastomers such as fluoroelastomers (FKM or Viton®), Vamac®, or Aflas® may be required.
What types of non-marking automotive rubber bumpers can CRG supply?
CRG can supply non-marking rubber bumpers in a variety of shapes and sizes to support specific vehicle programs and applications. Our rubber bumpers are molded using the highest quality materials and conform to all customer requirements. We can supply bumpers of almost any shape or size, including those of round, square, rectangular, elliptical, or other geometries. Because every non-marking rubber bumper we produce is purpose-built to support a specific application, our bumpers offer exceptional shock absorption, resistance to stress cracking, and non-marking properties.
In supplying non-marking automotive rubber bumpers, CRG works with each customer early in a project to assist with part design and material selection. Parts are developed to meet all quality standards using a Production Part Approval Process (PPAP).
In final part production, CRG uses proven processes while adhering to recognized quality standards, such as ISO 9001:2015, to ensure reliable and consistent part quality. In every project, we maintain our commitment to 100 percent on-time delivery, whether utilizing demand-pull replenishment or JIT scheduling.
CRG supplies parts which meet ASTM D1056 line call-outs, as well as the material specifications of major OEM’s, including those of General Motors, Ford, Chrysler, Nissan, Mazda, BMW, Honda, Toyota, Volvo, and Mercedes-Benz. Where a new specification is required, we work with our supply chain partners to develop an appropriate solution that meets or exceeds all requirements.
