What MAC Engineering & Equipment does

MAC Engineering & Equipment Company, Inc. is a privately held, Michigan-incorporated manufacturer of custom automated manufacturing equipment for the lead-acid battery industry, founded in 1965 by Charles McAlpine and operating from Benton Harbor, Michigan. The company designs and builds purpose-built machinery spanning the full battery production workflow — feeders, pasters (cast grid and continuous strip), flash dry ovens, parters, stackers, cast-on-strap (COS) machines, heat sealers, acid surfacers, and rack handling systems — under multiple product brands including optaMAC, dynaMAC, flowMAC, supraMAC, and MACvac, plus the Tiegel sub-brand for dry charge and water filtration. Equipment integrates on Allen-Bradley Control/Compact Logix PLCs with Panel View Plus HMIs and incorporates proprietary technologies such as MAC Thick Wall Hopper paste dispensing and FCC double-sided pasting.

The company operates a direct enterprise field-sales model: each customer is assigned a dedicated sales person and project engineer from consult through delivery, with field technicians for installation and ongoing after-sale support. Pricing is quote-based, with each machine purpose-built to customer specifications; the company does not publish list pricing. Beyond new equipment, MAC generates recurring revenue through spare parts (it is a certified supplier for CMWTEC in USA/Canada and Kustan in USA) and field service contracts.

MAC's geographic footprint combines a US headquarters with a wholly-owned India subsidiary (Pune) and a channel partnership with Sorfin Yoshimura providing sales coverage in USA (NY), France, China, Mexico, Thailand, Brazil, and Japan. The company maintains leadership continuity through founder-family Chairman Julie McAlpine McClure (succeeding original founder), President Doug Bornas, and an executive team including VP-level sales, engineering, and plant management roles. The company celebrated its 60th anniversary in April 2025.

Broad incumbents

• Manz AG: German automation specialist serving lithium-ion battery cell production, electronics, and other industries. Represents the type of larger, well-capitalized automation competitor that MAC would face if it pivots from lead-acid to lithium-ion production equipment.
• Digatron Systems: Global supplier of battery formation and test equipment, predominantly for lead-acid and lithium cells. Sells to many of the same battery manufacturers as MAC but focuses on the formation/testing stage rather than plate making.
• Bitrode (a Sovema brand): Manufacturer of battery formation, testing, and charging equipment for lead-acid and lithium batteries. Serves many of the same OEM customers as MAC for downstream testing processes, making it an adjacent incumbent in the broader battery production equipment space.

Direct peers

• Wirtz Manufacturing: US-based manufacturer of continuous grid casting and battery plate production equipment for lead-acid batteries. Direct competitor in the same product categories (pasters, casters, plate processing) and similar customer base of North American battery manufacturers.
• Kustan GmbH: German manufacturer of battery production equipment including COS (cast-on-strap), assembly, and plate processing lines. While MAC is a certified spare parts supplier for Kustan in the USA, the two companies compete in core equipment categories globally.
• Sovema Group: Italian manufacturer of lead-acid and lithium battery production equipment including curing chambers, plate processing, and formation. MAC already co-brands a 'Sovema by MAC Curing Chamber' product, confirming tight product overlap and channel relationship in the same niche.
• CMWTEC (CMW Teknik): Chinese/German battery equipment manufacturer with broad coverage of lead-acid battery production lines including plate making, formation, and assembly. Direct competitor to MAC with global installed base; MAC is a certified spare parts supplier for CMWTEC in USA/Canada.

Others

• Sorfin Yoshimura: Global sales representative network for battery production equipment. While technically a channel partner to MAC, Sorfin also represents competing equipment lines in some markets, making it a strategic dependency as well as an adjacent ecosystem player.
