Frequently Asked Questions (FAQ)

What makes a spring suitable for medical devices?

Medical-grade springs must meet strict performance, cleanliness, and quality standards. They are designed with tight tolerances, controlled forces, and biocompatible materials when required. At Tollman Spring, all components are manufactured under ISO 9001:2015 quality systems to ensure patient safety and regulatory compliance.

What is the difference between a constant force spring and a power spring?

A constant force spring delivers a nearly constant pull force throughout its range of motion, making it ideal for drug-delivery systems and wearable medical devices. A power spring, on the other hand, is housed between an inner shaft and casing and generates torque—commonly used in compact devices that require rotational energy.

Can Tollman Spring support early-stage medical device development?

Yes. Our engineering and design team works directly with OEMs at the concept stage to develop prototypes, improve existing designs, and shorten time-to-market. Early collaboration often reduces cost and ensures components meet performance requirements.

What materials are commonly used for medical springs?

Common materials include stainless steels (302, 304, 316), music wire, and specialty alloys depending on performance, corrosion resistance, and biocompatibility requirements. Tollman Spring offers flexible material capabilities to meet the needs of each device.

How does Tollman Spring ensure quality and compliance?

We are ISO 9001:2015 certified and utilize Statistical Process Control (SPC) on critical dimensions, as well as PPAP documentation where required. Our clean production environment and quality assurance program are designed to exceed the standards of top medical OEMs.

What delivery and packaging options are available?

We provide JIT and Kanban deliveries supported by 25,000 sq. ft. of climate-controlled warehouse space. Packaging is customized—using tacky boards, tubes, bundles, or pins—to prevent tangling or damage and ensure springs arrive in production-ready condition.
