Project Overview
EPDM compression seals are widely used in bridge expansion joints, metro systems, and infrastructure sealing applications.
This project involves custom EPDM extrusion seals manufactured for Thailand infrastructure, with strict hardness control and stable batch production.
The seals are designed to provide reliable sealing performance under demanding outdoor conditions, including temperature variation, vibration, and long-term exposure.
EPDM material offers excellent resistance to weather, UV, and temperature variation, making it ideal for long-term outdoor sealing applications.
This is a long-term repeat order with stable demand, demonstrating consistent product performance and supply capability.
Due to confidentiality requirements, the end customer information is not disclosed.

Production & Delivery
This project has been produced multiple times, with each order typically around 1000 meters of extrusion length.
For this shipment, the goods were packed into two pallets with defined dimensions, quantities, and weights to ensure safe transportation.
Hardness Control & Sample Approval
Hardness control is one of the most critical requirements for this project.
Before mass production, samples were manufactured and sent to the customer for testing and approval. After confirmation, the hardness range was finalized at 56–60 Shore A.
During production, each batch was tested using Shore hardness testers to ensure consistency and compliance with the approved sample.
Manufacturing Process
The seals are produced using rubber extrusion, ensuring continuous profile consistency and dimensional stability.
