Custom Rubber Mouldings

At DLR Elastomer, we pride ourselves on offering a bespoke custom rubber moulding service, understanding application requirements, designing the parts, tooling & process to deliver the product to the clients’ exact and demanding performance needs.

Our technical team is happy to advise on materials best suited for your application. Where necessary, we can modify the existing compound and/or develop new compounds keeping the service performance conditions of your product in mind. In addition, we monitor and apply current developments in polymer technology and we use this knowledge to develop even more advanced materials which will benefit our customers.

Rubber component design can be critical to its performance. We offer advice on all aspects of product design, helping to enhance performance & service life. Working from a sample, sketch or drawing, we can quickly select the materials required to provide a quotation for parts and associated tooling.

A key part of our offering is the ability to provide rubber to metal bonded components. In addition to this, some dynamic applications require textiles as an essential part of the design. These textiles impart strength & longevity to the part; polyester, polyamide, metal and carbon fibre are some of the textile materials used in rubber components.

Relevant Industries

Custom rubber mouldings are used in many industry sectors – the most demanding applications require bespoke solutions such as rubber to metal bonded parts for engine mounts and specialist rubber, fabric composites for the defence industry.

The well known under-bonnet temperature increase has been resolved mainly by using high-performance polymers with the capability of withstanding temperatures in excess of 200°C. Some of the rubber mouldings commonly encountered in a car include O-rings, seals and grommets. 

Rubber mouldings are required to resist oils and greases as well as dirt, water, and weathering. Many custom rubber moulding solutions are subject to dynamic loading, including engine mounts and exhaust hangers. Applications requiring the best oil and chemical resistance and good ageing in hot fuel vapours are accommodated using high-performance fluoro (FKM) and fluorosilicone (FVMQ) elastomers.

The bonding of rubber to other substrates is a crucial part of being able to offer novel solutions. DLR has a wealth of experience when it comes to the preparation of metal for rubber-to-metal bonding.

DLR is a supplier to all three arms of the UK Armed Services via the MoD and; other national armed forces and defence contractors. Supplying rubber products for the defence industry is demanding; quality and performance are paramount, specifications rigorous and reliability of supply vital. DLR is one of the Royal Navy’s oldest current suppliers.

The designs and products have had to keep pace with developments in the defence industry. Accordingly, we have adopted new material technologies & optimised our materials & processes to meet the specific demands placed on polymer-based products for a diverse range of military applications.

DLR manufactures high-temperature and high-pressure rubber seals and packers for the oil and gas (storage) industry for both wellhead or Christmas tree applications. We also manufacture vapour barrier materials that provide secondary sealing for large storage tanks to prevent vapour losses, along with packers for oil and gas applications.

We combine our rubber compounding expertise with our precision rubber moulding capabilities to produce high-performance that withstand extremes of temperature and pressure to American Petroleum Institute (API) standards. And in an environment where safety is a paramount concern, our products can be relied upon.

This industry requires careful selection of materials - purity is essential, as is the chemical nature of the products used. For example, polyisoprene rubber (IR) is used in applications due to the proteins present in natural rubber (NR). There are many impurities in general rubber compounding ingredients that must be avoided for use in these applications.

Medical applications require some products to undergo stringent cleaning regimes together with repeated steam sterilisation. When developing the rubber compound and part design, these considerations are taken into account - resistance to steam and cleaning products is essential.

Custom Rubber Moulding FAQs

CAN RUBBER BE BONDED TO METALS?

Many applications require that rubber be bonded to metals. Examples include engine mounts and bushes, whilst the aim in these two cases is to stop two metal surfaces rubbing together, this technique also ensures vibration isolation.

The rubber-to-metal interface is critical and requires particular attention when preparing the surfaces to be bonded for the application of any surface treatments, primers, or bonding agents.

Most substrates can be bonded together, some are more difficult than others and require specialist materials knowledge.

The bond is typically tested and deemed as good when the bond strength is greater than the strength of the rubber. This will result in the rubber breaking rather than the bond.
