Our Story

MSR was set up in 1950 as a manufacturer of rubber parts for the automotive industry.
With an increase in demand for rubber, the Company embarked on an expansion programme and in 1969, the production was relocated to a larger factory built by Jurong Town Corporation.
In 1973, the Company expanded into the production of technical and precision parts for the OEM manufacturers as well as the marine and the heavy industries.

MSR collaborates with major MNCs providing our customers with high performance synthetic rubbers material like “Viton”, “Aflas”, and “Hypalon”.

MSR commitment is to deliver better quality, inventory, service and delivery. in 1996, we acquire a factory in Tuas, this adding up our operations for gasket sealing products, rubber molding, plastic injection, Polyurethane (PU) casting and rubber lining and raw rubber compounding.

To ensure a consistently high quality of goods produced, a laboratory was set up in 1995. We are consistently improving our testing facilities to ensure that quality is not compromised with better and better valued products. We are compounding the rubber material in-house (Silicone, Viton, Neoprene, etc ) to make the final finished product (O rings, gaskets, molded parts, etc). We always choose high quality raw materials ,chemicals, and polymer from quality suppliers so that you can be sure you will be getting the rubber material specification that is needed to make the final finished products.

Upon customer’s request, the company had also set-up a plastic injection department to service their needs.

For our standard and stocked items, we can provide the specification of our standard and stocked items.

For customised products, with our vast years of experience in manufacturing, we are able to produce according to your required specification. However, if upon requests by user, we can also send our products for certification by a third party for testing. We are confident of producing according to your specification/sample and quality is consistent with your required specification or your sample.
