TECHNICAL RUBBER AND RUBBER-TO-METAL PARTS TO DRAWING

At Fabricats Mimsa we have been manufacturing technical rubber parts since 1974 at our plant in Rubí (Barcelona, Spain). We work with injection, compression and transfer moulding, and we also produce rubber-to-metal parts with metal inserts.

We manufacture to the customer’s drawing or develop the part to measure, in large or small series, using the latest machinery and technology.

The manufacturing process of rubber parts requires rigorous control, so we always use the latest technology which enables us to monitor the entire production process and achieve the best results.

Our wide experience as manufacturers enables us to provide advice on the ideal material for each application: EPDM, NBR, CR or Viton (FKM).

Our main market is the automotive industry, with IATF 16949:2016 certification. We also supply general industry, agriculture and railways, with ISO 9001:2015 certification. In 2025 we manufactured 1,924,970 rubber parts, 25% more than in 2024.

TYPES OF MATERIALS

At Fabricats Mimsa we have a wide range of materials and different types of rubber that we select for our clients according to the needs of each project.

TABLE OF MATERIALS

PRODUCT FAMILIES

Six families of technical rubber parts manufactured in series for the automotive industry and general industry, to drawing or custom-made.

Bellows

Rubber bellows that protect joints, shafts, cables and mechanisms from dust, water and dirt while allowing movement. We manufacture round bellows and gear-shift boots for the automotive industry and industrial machinery. Typical materials: EPDM and NBR, depending on exposure to weathering or oils.

Grommets

Rubber grommets for routing cables and tubes through sheet metal and panels, sealing the opening and protecting the cable from cuts and vibration. We make custom grommets to suit panel thickness, diameter and number of passages. Typical material: EPDM.

Seals and gaskets

Technical rubber seals that keep out water, air, dust, oils and fuels. We manufacture them to drawing, in the shape and hardness each application requires. We choose the material according to fluid and temperature: EPDM, NBR, CR or Viton (FKM).

Tank seals

Tank seals for leak-tight closure of tanks and their caps, including versions with an integrated bellows (soufflet). This is one of our families with the most series references for the automotive industry. Typical material: NBR, for its resistance to fuels and oils.

Dampers

Rubber dampers and bump stops that absorb vibration, impact and noise between metal or plastic parts. They are designed with the hardness and geometry each load requires. Typical material: EPDM.

Metal-insert parts

Rubber-to-metal parts in which the rubber is moulded and bonded directly to a metal insert, as a single part. They are used as mounts, anchored bellows and anti-vibration elements. We manufacture them by injection or compression moulding with the insert placed in the mould.

FREQUENTLY ASKED QUESTIONS

Lead times, materials, moulds and certifications: what customers ask us most before starting a project.

What types of parts do we manufacture?

Technical rubber parts: bellows, grommets, seals, tank seals, dampers and rubber-to-metal parts with metal inserts. We manufacture to drawing or custom-made.

Which materials do we work with?

EPDM, NBR, CR and Viton (FKM) rubbers. We help you choose the material according to temperature, fluids, weathering and hardness. See our materials table (PDF).

Which manufacturing processes do we use?

Injection moulding (including vertical injection presses), compression and transfer moulding. We also manufacture rubber-to-metal parts with metal inserts.

Can we manufacture from your drawing?

Yes. Send us the drawing or a sample and we will study the most suitable material, mould and process. If you have no drawing, our development team can design the part with you.

Do we produce short runs or only high volumes?

Both. We produce long series for the automotive industry as well as small batches for general industry. In 2025 we manufactured 1,924,970 rubber parts, 25% more than in 2024.

Which certifications do we hold?

IATF 16949:2016 for the automotive industry and ISO 9001:2015 for general industry. Every part goes through a final visual and dimensional inspection by machine vision.

Which sectors do we work for?

Mainly automotive, as well as general industry, agriculture and railways. We export to customers on five continents.

Who makes the mould?

An accredited external mould maker builds it from the drawing approved by the customer. We manage the whole process and the mould is owned by the customer.

How long do we take to deliver the first parts?

4 to 6 weeks from drawing approval to the first samples, depending on the complexity of the mould.
