Product overview

Based on the existing corrugation types and their generation mechanisms, Rail Corrugation Suppressor is proposed to develop special products corresponding to corrugation types (frequencies) that are common at present based on the original development experience.

A mass spring damper can be obtained by adding elastic layer, main resonance mass block and secondary resonance mass block on the rail web and rail wing of existing lines, to effectively suppress or reduce abnormal rail corrugation caused by wheel-rail friction-induced self-excited vibration in special frequency bands. Rail Corrugation Suppressor can be used in sections with abnormal rail corrugation of existing lines to effectively improve or suppress line corrugation.

What we do & Why choose us?

Changmei Technology has been designing, manufacturing, and exporting Rail Corrugation Suppressor / Rail Grinding Mitigator for about 10 years.

Our rail corrugation suppressor is a highly customized product. Every unit is designed based on the customer’s own rail corrugation measurements. This isn’t off-the-shelf — it takes expertise. And that’s where we come in. With years of experience in custom manufacturing, we know how to deliver solutions that actually fit the problem. So if you’re dealing with corrugation and need something built specifically for your track conditions, we’re probably your best choice.

Production Capacity & Delivery

Our production capacity

We run a 9,000 m² manufacturing facility with:

22 injection molding machines

5 compression molding machines

20 pieces of auxiliary equipment

Yearly output:

15 million nylon and polyester products

100,000 rail power protection units

500,000 vibration & noise damping products

Lead time for custom orders

Custom work takes a bit longer — and that’s because we build it right. Once we have all your technical data, we’ll get back to you within three weeks with a solution, after confirmation with you we’ll starting production process. After that, production time runs 1 to 3 weeks, depending on how many pieces you need.
