FAQs About Custom Rubber Molding Companies & Services

What is custom rubber molding?

Custom rubber molding is the process of designing and manufacturing rubber parts tailored to specific applications, material requirements, unique resistances, and a range of forces, pressures, toughness, and appearances. Rubber molding companies employ methods such as compression, transfer, and injection molding, or a combination of these methods, to produce components including seals, gaskets, bumpers, isolators, and numerous other industrial and consumer goods.

Why choose a U.S.-based custom rubber molding company?

Working with a domestic custom rubber molding company offers faster lead times, reliable communication, stable supply chains, and the ability to collaborate more closely during the design and production process. It also reduces the risks associated with overseas shipping and quality control considerations, such as ISO 9001 or 13485 for medical applications.

How do I choose the best custom rubber molding company?

This choice greatly depends on several individual factors, including turnaround times, budgets, locations, and materials. It’s best practice to look for a company with:

• Proven experience in your industry or with specific rubber compounds
• ISO 9001, AS9100, ISO 13485, or other quality certifications
• In-house engineering and tooling support for material selection and design
• Competitive costs that do not sacrifice quality or efficiency
• Strong customer testimonials and case studies
