Global Leadership in
& Vibration Control

Pioneering the future of special rubber damping and sealing products for extreme environments.

As a dominant force in the rubber and plastics industry, our rubber cushion series represents the pinnacle of industrial damping technology. We leverage proprietary polymer compounding and precision molding to ensure that every component meets stringent international standards for durability and performance.

Our technical edge lies in the ability to customize Shore hardness and compression sets to match specific machinery frequencies. By integrating high-damping EPDM and Natural Rubber, we provide a rubber cushion that offers superior resistance to ozone, heat, and chemical exposure, ensuring zero-failure operation in the most demanding sectors.

Frequently Asked
Questions

Expert answers to common technical and commercial inquiries.

01

How do I choose the right hardness for my rubber cushion?

Selection depends on the load-to-surface-area ratio and the required resonance frequency. We provide a technical consultation to match the Shore A hardness to your machinery's specific vibration profile.

02

Which material is best for oily environments?

For oil-heavy applications, we recommend Nitrile (NBR) or Fluorocarbon (FKM). These materials prevent swelling and structural breakdown when exposed to synthetic oils and fuels.

03

Can you manufacture custom shapes based on CAD files?

Yes, we specialize in custom molding. You can provide STEP or IGES files, and our engineers will optimize the design for the molding process to ensure structural integrity.

04

How do you ensure the durability of cushions in extreme cold?

We use specialized EPDM or Silicone blends that maintain elasticity at low temperatures, preventing the "glass transition" effect where rubber becomes brittle.

05

What is the typical lead time for bulk orders?

Depending on the complexity and material, bulk production usually takes 15-25 business days after mold approval. We offer expedited shipping for critical replacement parts.

06

Are your rubber cushions compatible with high-voltage equipment?

Yes, we provide specialized dielectric-grade silicone cushions that offer high electrical resistance and prevent arcing in power transformer mounts.
