Gestión de Compras has extensive experience in the design, development and manufacture rubber parts by compression and transfer.


Compression molding and transfer molding are two main methods for producing rubber parts. Meanwhile compression molding is useful for making large parts where tightest tolerances and flawless finishes are not required, transfer molding is widely used to enclose or encapsulate items.

Compression and transfer molding are similar processes, on the next diagram is possible to see the differences and similarities on the operations:

Compression-Transfer molding process 1

Compression molding advantages:

  • Low tooling costs
  • Make intricate products
  • Rapid production
  • Accept a large range of materials
  • Useful to make large parts
  • Least amount of waste
  • Short set up time
  • Accept high durometer materials

Transfer molding advantages:

  • Higher production rate
  • Low production costs
  • Complex products
  • Thicker walls
  • Good surface finish
  • Fast mold set up


In Gestión de Compras we have an extensive experience in the design, development and manufacture rubber parts by compression and transfer. We have the versatility forget parts of products according requirements and drawings of customer, but we also work with standard products.

We work with most of material and rubber molding processes because we have the support of factories equipped with state-of-the-art machines and tools to get the desired products.

The most used materials used on compression and transfer moulding are thermoset polymers. Also resin transfer molding allows for a composite material to be made by placing a fiber within the mold and subsequently injecting the thermosetting polymer. By these methods it’s also possible produce metal-rubber parts. Following some examples of materials used on these two methods:

  • Epoxy resins
  • Unsaturated polyester resins
  • Vinyl ester resins
  • Elastomers (Neoprene Rubber, Silicone Rubber, EPDM Rubber, Viton Rubber, Vinyl Rubber, etc.)

These two methods are useful to make oil rings, gaskets, seals, integrated circuits, plugs, connectors, air gauge guard, bumpers, solid tires, strain relief protectors, gaskets, grommets for vibration isolation, slit grommets, spools, isolators for automotive application.

Although these two methods can´t obtain narrow tolerances, transfer molding produces parts with better consistency that compression molding, allowing tighter tolerance and more intricate parts.


Our factories have the most demanding certifications for customers to ensure product quality as:

  • ISO 9001.
  • TS 16949.
  • ISO 14001.
  • ISO 295.
  • DIN EN 289.
