DSB and Tundra Announce Partnership

Enabling Large Part Production in MIM With New Feedstock System

JANESVILLE, WI. July 19, 2021

DSB Technologies, a leading metallurgical solutions provider, and Tundra Technologies LLC, a leading polymer additives, coatings, and composites company, today announced a partnership that will enable high-volume production of large, complex metal injection molding (MIM) components. Beginning immediately, DSB will operate as the preferred production partner for parts made with Tundra's Dynamik® materials platform, including metal composite feedstocks and powders.

By leveraging DSB's metallurgical production expertise and Tundra's successful track record in coating materials, customers can produce larger and more complex parts previously not possible in MIM.

"It takes a strong partnership between dedicated materials and engineering experts to solve the challenging obstacles that are present in the injection molding space today," said Paul Hauck, Chief Operating Officer at DSB Technologies. "Partnering with Tundra, a company with a background in leveraging advanced technical insights to reinvent what's possible advances our strategy to design and produce MIM components with properties and possibilities that the market has never seen before."

With traditional MIM materials, the uncertainty of isotropic shrinkage significantly increases with larger parts, often creating high part variability, low dimensional stability, and expensive material processing. These obstacles have kept most MIM components around the size of 25 grams or less. Dynamik® offers high particle concentration materials that can be processed on established equipment which enables large, complex part production in MIM - including part sizes greater than 100 grams. Other beneficial material characteristics include:

  • High dimensional stability, producing near-wrought properties and reduced part variability
  • Average isotropic shrinkage of 10-12%, compared to traditional shrinkage of 16-20%
  • Improved particle packing - up to 87% by volume - allows for lower sintering temperatures and improved isotropic characteristics
  • Competitively priced powders and feedstocks in multiple alloys

"MIM has had a successful history in delivering very complex metal parts for demanding applications, but its scope has been limited to small parts," Hauck said. "Our partnership with Tundra enables us to address a broader range of applications that were not economically possible with traditional MIM operations, expanding how our customers can leverage the technology for their applications."

DSB's growing Technology Center offers the largest capacity of high-temperature sintering in North America and continues to grow its investments in MIM technology through new talent and equipment. DSB recently announced the addition of an ELNIK high temperature refractory metal lined vacuum furnace and an Arburg automated molding press to its fleet of MIM equipment, offering customers the metallurgical expertise needed to lead the development of non-traditional MIM applications.

This partnership reinforces DSB's commitment to market diversification as a crucial element of its growth strategy to bring new technology to a range of markets, applications, and customers. With Tundra's specialty additives and composite materials expertise, DSB offers a scalable approach to large-volume MIM production with greater dimensional control and large part-size possibilities at a competitive cost.
