Custom New Product Rubber Molded Parts

The Art of Material Selection

A custom molded part is only as good as the compound used to create it. One of the primary values we offer our clients is our expertise in material science. Rubber is not a monolith; it is a vast family of polymers, each with distinct characteristics.

In our facility, we work extensively with a wide range of elastomers to match the specific environment your part will inhabit:

Silicone: For applications requiring extreme temperature resistance (from -60°C to 230°C) and biocompatibility, we mold medical-grade and food-grade silicone. It is ideal for healthcare devices and kitchenware.

FKM (Viton®): When chemical resistance is non-negotiable, such as in fuel systems or aggressive chemical processing, our FKM compounds provide superior stability.

Neoprene & NBR: For general-purpose industrial parts requiring a balance of oil resistance and durability, these remain our workhorse materials.

EPDM: The go-to choice for outdoor applications due to its resistance to ozone, weathering, and water.

We do not just buy off-the-shelf rubber. We formulate and mix our own compounds in-house. This allows us to adjust the durometer (hardness), tensile strength, and color to meet your exact specifications. If you need a part that is soft to the touch but rigid under compression, or one that is conductive or flame-retardant, we can tailor the chemistry to make it happen.

Precision Tooling: The Foundation of Quality

The difference between a "rough" rubber part and a "precision" part lies in the mold. We operate a state-of-the-art tooling department where our engineers design and build molds with micron-level accuracy.

We specialize in complex geometries that other factories might shy away from. Whether your design requires intricate undercuts, tight tolerance bores, or multi-cavity configurations, our tooling team ensures that the mold flow is optimized to prevent defects like air traps or incomplete cures.

By controlling the tooling process, we can also offer rapid prototyping. We understand that in the product development phase, speed is currency. We can move from a CAD file to a physical sample in a matter of days, allowing you to test fit and function before committing to full-scale production.

Molding Capabilities: Compression, Transfer, and Injection

Different parts require different molding methods. Our factory floor is equipped to handle the full spectrum of rubber molding technologies, giving us the flexibility to choose the most cost-effective and efficient method for your project.

Compression Molding: Ideal for lower volume runs or large, heavy-duty parts. This traditional method involves placing a pre-form of rubber into a heated mold cavity and applying pressure. It is cost-effective and excellent for simple shapes.

Transfer Molding: A middle ground that offers better precision than compression. The rubber is heated in a pot and then forced into the mold cavities. This is perfect for parts with delicate inserts or complex shapes.

Injection Molding: For high-volume production runs requiring tight tolerances and minimal flash (excess rubber), injection molding is our premier choice. It allows for faster cure times and the ability to mold rubber bonded to metal inserts with high precision.

Quality Assurance You Can Trust

In industries like medical and automotive, failure is not an option. Our Quality Control lab is equipped to perform the tests that validate our parts. We conduct routine checks for hardness (Shore A/D), tensile strength, elongation, and compression set. For critical components, we can perform chemical compatibility testing and aging tests to simulate years of wear in a matter of weeks.

We are ISO-certified and committed to maintaining a production environment that prioritizes consistency. When you order 10,000 parts, the first one and the last one will be identical in form and function.
