Rubber transfer moulding is a versatile manufacturing process used to produce precision rubber components with excellent dimensional stability and intricate designs. This process involves transferring pre-measured amounts of rubber material into a heated mould cavity under pressure, resulting in consistent and uniform parts with minimal wastage.

Here’s how the process works:

  1. Material Preparation:
    The rubber material, usually in sheet form is cut to the appropriate size using a slitter table or guillotine. Alternatively the material can come in preformed blanks which are extruded and cut to length and size. The rubber is then weighed out to a predetermined amount ready for loading into the transfer pot.
  2. Loading the Material:
    In transfer moulding, the rubber material is loaded into a chamber called the pot or transfer chamber located below the mould cavity. This chamber is equipped with a piston that will apply pressure and transfer the material into the mould cavity.
  3. Heating:
    The mould and the rubber material are heated to a specified temperature to soften the rubber and facilitate the moulding process. The temperature and heating duration are carefully controlled to ensure proper flow and curing of the rubber.
  4. Transfer and Compression:
    The piston applies pressure to transfer the material from the pot into the mould cavity. The rubber flows through channels or runners (sprues) into the cavity, filling it completely.
  5. Curing:
    After the mould cavity is filled with the rubber material, the entire mould assembly is subjected to heat and pressure to cure the rubber. Curing involves cross-linking the polymer chains within the rubber compound, resulting in the formation of a stable and durable rubber product.
  6. De-moulding:
    Once the curing process is complete, the mould is opened, and the finished rubber product is removed from the mould cavity. Any excess material, known as flash is removed from the mould ready to start the process over again. The product will receive a primary quality check then set aside too cool.
  7. Finishing procedures:
    Depending on the specific requirements of the product, additional post-processing steps such as surface finishing, trimming and secondary quality check will be performed, to ensure the final product meets the desired specifications and standards before being shipped to the client.
