FAQ

Looking to find out more about Martin’s Rubber and our capabilities? Ever wondered what the actual design process entails and the advantages of certain moulding processes? Look no further. Read through some of our most frequently asked questions below.

Can bespoke rubber products be supplied by Martin’s Rubber?

Yes, at Martin’s Rubber we look to create the most effective rubber solution to meet your project requirements, whatever they may be. It is important to remember that the customer remains responsible for warranting the effectiveness, safety and performance of any industrial rubber design or any alternative proposed by Martin’s Rubber, as well as the proving of samples or production parts in service.

What does the design process entail?

The design stage of rubber and elastomeric components can vary from the creation or modification of 3D files to the provision of 2D drawings for parts, as well as Finite Element Analysis. Although we do not offer design services to generate original parts from scratch, we do work with customers to refine the design of their product.

The optimal approach is to involve our technical team from the very start of a project. This is important, as it prevents wasting design time or incorrect material selections. Customers have often approached us with high-cost products already in use that do not work. In such cases, we can reverse engineer a solution to help them solve their problem.

Will Martin’s Rubber assist in the design process?

Yes, our staff have the technical expertise to help guide you on specific projects. Although we do not directly design rubber products ourselves, we can offer a consultation service to designers, where we make suggestions regarding:

  • Product design
  • Material selection
  • Tolerance bands
  • Intangible factors such as feel and smell

What are the benefits of compression moulding?

Compression moulding can be used for large or intricate parts where a flat gasket would not be suitable. Compression moulding can offer a lower cost than other types of moulding processes, as the process does not require an injection or transfer cycle.

Compression moulding is also perfect for large parts that require a significant amount of material for manufacturing. The material can be directly loaded into the mould cavity so there is less limitation on the weight of part they can produce.

What are the benefits of injection moulding?

Some of the benefits that injection moulding offers include the fact that it can be used to produce very small parts, therefore it is perfect for both high-output production or fast production. You can also rest assured that injection moulding offers a good level of product consistency, so you can be sure your product will perform as expected.

General rubber information

 

What is rubber made of?

Natural rubber is made from a liquid substance that oozes from some plants when you cut into them. This substance is called latex and it is commonly found in dandelions. For example, if you snap off a dandelion stem you will be able to see the latex dripping from the bottom. There are also several species of trees that produce rubber, including the Hevea Brasiliensis and those from the mulberry and fig families.

What are the properties of elastomers?

  1. Withstands extreme temperature
  2. Endures multiple complex chemicals
  3. Electrical insulator or conductor
  4. Excellent rebound characteristics
  5. Exceptional damping & thermal conductivity

How to bond rubber to steel parts

  1. Cut the profile of the rubber material to form the most robust bond. A dovetail joint is often the most effective solution.
  2. Prepare the material using a mechanical buffing technique.
  3. Apply a liquid compound to the joint in preparation for vulcanisation.
  4. Place the joint under heat and pressure to cure the rubber
  5. This method will provide a different type of bond than adhesive alone

How was vulcanised rubber made?

Vulcanised rubber was made reputedly by accident. Charles Goodyear dropped a sheet of fabric infused with rubber, sulphur and white lead onto a hot stove. Rather than melting, the fabric hardened into a permanent flexible state, and was far less affected by extreme heat than it had been. When placed in a steam oven under pressure, the combined rubber and sulphur cured to form a stable material that had good mechanical properties.
