Manufacturing tailored Rubber Moulded components to exacting specifications.

Working with our Client’s to provide optimal custom moulded rubber solutions.

Utilising injection, compression and transfer moulding methods, our rubber moulding capability ranges from micro moulding (precision rollers for credit card readers) to large bowl liners used in the gold mining industry. Synapco’s rubber production spans a wide range of materials – Nitrile, Viton, Silicone, Natural Rubber, Neoprene, and other specialised rubber polymers – all available in various hardnesses. We produce a variety of parts which are bonded to metal base components. Rubber grades are available to meet environmental extremes or for food or dairy, and other specific applications. Synapco has its own rubber mixing facility, so we can custom blend polymers to meet customers’ exact requirements.

Rubber Compression Moulding

Our plastics manufacturing facility is staffed by a team of experienced and dedicated operators. We have a full range of the latest ancillary equipment to ensure best industry practices and efficiencies are used – these include dehumidifier material drying systems, stainless lined batch mixers, mould coolers/heaters, and low/high speed granulators. We take great pride in our carefully controlled preventative maintenance system for all our production equipment and factory services, (including electrical, compressed air, and water cooling systems) which guarantee on time delivery to our customers.

This process is most suitable for:

  • low volume parts
  • price sensitive parts (less material waste than other processes)
  • large parts
  • basic forms.

Transfer Moulding

Transfer moulding involves a process where the rubber material is placed into a transfer pot, which fits tightly with a plunger plate. The material is then transferred through pressure and temperature from the transfer pot through sprues into the mould cavities. The advantages of transfer moulding include: ability to mould precision tolerances; less flash during the moulding process; ability to insert mould or over-mould metal, plastic, fabric, or rubber inserts; and increased tooling lifetime.

This process is most suitable for:

  • medium- to high-volume production
  • insert or over-moulding
  • high precision.

Rubber Injection Moulding

Injection moulding involves a process where the rubber is introduced into the mould through an injection nozzle and then injected into each cavity through a runner system, gates, or transfer sprues. The injection process is semi-automated and requires the least amount of material handling of any of the three rubber moulding processes. The advantages of injection moulding include: tighter tolerances; ability to utilise faster cycle times; and semi-automation to reduce part costing.

This process is most suitable for:

  • high volume production
  • fastest possible cycle time
  • price sensitive parts (less labour required than other processes)
  • high precision parts.
