Atek expanding Iowa plant, technical capabilities AFS Corporate Member ATEK

Metal Technologies (New Hamp- ton, Iowa) is expanding its plant and technical capabilities to keep up with demand. Te company has recently completed a significant expansion of its metalcasting, heat treatment and finished machining capabilities. “We added 40% to our low pres-

sure permanent mold casting capac- ity to keep up with our accelerating growth,” said Tom Christie, president,

ATEK Metal Technologies. “We also have added state-of-the-art precision machining capabilities to be able to provide our customers with cast and machined finished components.” ATEK has also invested in robotic de-gating and deburring of castings. Tis system will be operational in July. “We are applying automation where it makes sense for the safety of our people and to provide the best value possible for our customers,” Christie said.

Dotson Iron Castings honored with award

The Manufacturing Leader- ship Council announced that AFS Corporate Member Dotson Iron Castings (Mankato, Minnesota) has been recognized as a Manufactur- ing Leadership Awards winner for outstanding achievement in Col- laborative Innovation for its disaster recovery. Te award recognizes Dotson’s ef-

forts in recovering from a significant fire that took place in September 2017. As a result of the fire, three molding lines were lost, along with the conveyor

sand delivery system and all electrical, computer, pneumatic, and water lines in the molding and pouring area. Every piece of equipment in the plant had to be serviced due to the soot and residue. Dotson’s leadership team initi-

ated a comprehensive three-part plan focusing on employees, customers and rebuilding the foundry. Te leader- ship team and support individuals met twice daily on all aspects of recovery. Te Dotson philosophy going into this effort was to make sure every opportu- nity was taken to improve the opera-

ASTM makes foundry-related announcements

ASTM International made two an- nouncements related to standards that have implications in metalcasting.

Proposed standards support im- proved zinc diecasting alloys

ASTM International’s commit-

tee on nonferrous metals and alloys is proposing two new standards. One is for a zinc-aluminum-copper alloy with improved strength while the other seeks to determine the require- ments for die castings with thin walls which can help reduce industry costs. Te first proposed standard is

for an alloy that seeks to improve the elevated temperature strength compared to standard zinc die casting alloys while also improving castability. Creating the standard will involve

a review of the literature and data from work previously initiated by the International Lead Zinc Research Or- ganization (ILZRO) and the Council for Scientific and Industrial Research (CSIR). It will also include a review of data from other commercial alloys that are related to this work Te second proposed standard will

serve as a companion to an existing standard for high fluidity zinc alloy, (B989). It will provide composition requirements and consolidate the available physical and mechanical properties of these castings. “Te ability to produce strong zinc

castings with thin walls results in material savings and reduced secondary machining due to the superior net- shape capability of zinc casting,” said

member and committee chairman John Malmgreen, vice president, manufac- turing and quality, Eastern Alloys.

New ASTM International standard supports use of foundry sand in asphalt

A new standard will help the road and paving industry make better use of foundry sand in asphalt mixtures. Te new standard (D8140) was developed by the ASTM International commit- tee on road and paving material. Te guide covers the physical and

chemical requirements (grading, shape, density, toxicity) of virgin or recovered foundry sand used in asphalt mixtures. Contractors, foundry sand suppliers, and other relevant purchasers could benefit from the guide.

tions as the rebuilding took place. Dotson’s commitment to its em-

ployees and the community during the recovery process was especially notable. While continuing to pay employees, Dotson Iron Castings offered their services to various com- munity organizations in the Greater Mankato area while it worked to restore production facilities. While recovery efforts continue, in just over four weeks after the fire, with the help of countless people, Dotson was back pouring iron.

Te company is also planning a building expansion that’s scheduled to be completed in December. “We need additional plant space to

support growth,” Christie said. “Te new building will allow us to consoli- date our warehousing and shipping ar- eas and make room on the plant floor for ongoing expansion of operations.” Te entire plant expansion is

scheduled to be complete by the end of 2018.
