Custom Rubber Molding

Controlled Elastomer Forming for Functional Components

Rubber Molding as a Manufacturing Capability

Rubber molding is not about producing soft parts.
It is about controlling elasticity, sealing behavior, durability, and long-term performance under real working conditions.

Our rubber molding capability is focused on functional rubber components used for protection, sealing, vibration control, and environmental resistance in manufactured products.

Material Selection Based on Application

Different rubber materials behave very differently in use.

We work with a range of elastomer materials, selected based on application requirements such as:

  • Elastic recovery and compression set
  • Chemical and environmental resistance
  • Temperature stability
  • Mechanical durability

Commonly used materials include natural rubber, EPDM, NBR, silicone, fluorocarbon (Viton®), and other engineered elastomers.

Material choice is driven by performance needs, not availability.

Molding Processes Chosen for Stability

Different rubber components require different molding approaches.

We apply rubber molding processes based on part geometry, material behavior, and production volume, including:

  • Liquid silicone rubber (LSR) injection molding
  • Compression molding
  • Transfer molding
  • Rubber-to-metal bonding

Each process is selected to achieve stable dimensions, consistent material properties, and reliable repeatability in production.

Liquid Silicone Rubber (LSR) Injection Molding

LSR injection molding is used for high-precision rubber components that require clean surfaces, tight tolerances, and consistent material properties.

This process is well suited for:

  • Precision sealing components
  • Protective parts with complex geometry
  • Applications requiring stable mechanical and thermal performance

Process control focuses on contamination prevention, dimensional consistency, and repeatable curing behavior.

Compression and Transfer Molding

Compression molding is typically applied to low- to medium-volume production and larger rubber components where material efficiency and tooling simplicity are important.

Transfer molding is selected when:

  • More complex geometries are required
  • Improved dimensional control is needed
  • Rubber-to-metal bonding is involved

Both processes are evaluated based on part function, material characteristics, and long-term production stability.

Tooling and Mold Design for Rubber Parts

Rubber molding quality depends heavily on mold design.

We design rubber molds with attention to:

  • Parting line control
  • Venting and material flow
  • Consistent curing conditions
  • Ease of maintenance and service life

Tooling is developed to support repeatable production, not just initial sampling.

From Prototyping to Production

Rubber components are often critical to product performance.

During development and trial stages, we validate:

  • Fit and sealing behavior
  • Compression characteristics
  • Durability under repeated use

This approach reduces risk before full-scale production and ensures rubber components perform as intended over time.

What You Can Expect From Our Rubber Molding Capability

  • Functional rubber parts with predictable performance
  • Materials selected for real application conditions
  • Stable molding processes
  • Smooth transition from tooling to production

Rubber molding delivers value only when material, tooling, and process are aligned.
That is how we approach it.

Good rubber components are rarely noticed.

They simply keep products working.

That is the role we design for.
