Griner Engineering

What Griner Engineering does

Griner Engineering, Inc. is a precision turned parts contract manufacturer founded in 1978 in Bloomington, Indiana, operating from a 54,000 sq ft facility housing 13 Hydromat rotary transfer machines, 18 Acme-Gridley multi-spindle screw machines, and 14 CNC/Swiss-style lathes. The company produces high-volume sensor bodies (including airbag and ABS pressure sensors), mechanical components (brake mechanisms, EV cooling pumps), fluid handling parts, and construction equipment components for North American OEMs in transportation, aerospace, medical, and electronics end-markets, with a documented 4 million-part-per-year zero-defect capability for safety-critical ABS solenoid sensor bodies.

The business operates three divisions: a core precision parts manufacturing segment (quote-based, multi-year contracts, 100,000+ piece minimums for Hydromat pricing competitiveness), a Heavy Rental Forklifts division offering 15,000-80,000 lb capacity equipment in South Central Indiana, and a Machinery Movers division handling loads up to 100,000 lbs. GTM is sales-led and relationship-based, with orders initiated through direct contact ([email protected], phone) and quote request forms. Pricing for the manufacturing segment is opaque and negotiated; pricing for the equipment rental and machinery moving segments is publicly listed with daily, weekly, and monthly rate cards. Quality credentials include Ford QS 9000 (1998) and TS16949 (2006) certifications and long-standing PMPA membership.

In late 2024, Griner was acquired by OHM Advisors (a Livonia, MI-based architecture and engineering firm) alongside THY Inc. in Memphis, Tennessee, with Viking Mergers & Acquisitions advising. The deal is positioned to expand OHM's engineering services footprint into Florida and Tennessee. Following the change of control, Griner's three operating divisions continue to function under the Griner Engineering umbrella as part of OHM Advisors' infrastructure and civil engineering capabilities.

Scale indicators5 records

Recent moves6 records

Expansion highlights5 records

Broad incumbents

• Hyster-Yale Materials Handling: Public manufacturer of forklifts and material handling equipment, comparable to Griner's Heavy Rental Forklifts division and overlapping customer base for industrial lift equipment.
• Shiloh Industries: Public automotive supplier of precision components including engineered metal products, providing overlap with Griner's automotive sensor and mechanical component work but at much larger scale and broader scope.
• Barnes Group Inc. Diversified industrial manufacturer with precision components, engineered parts, and fluid control businesses. Comparable as a broader industrial-machined-components incumbent serving aerospace and industrial markets.
• Manitowoc Company: Established manufacturer of cranes and construction equipment with a significant machined components supply chain. Comparable through Griner's construction equipment parts segment.

Direct peers

• Dynacast: Global precision metal component manufacturer using high-volume multi-slide and screw machining processes for automotive, industrial, and consumer markets. Highly comparable in production technology and end-market exposure.
• Hydraforce: Manufacturer of hydraulic valves, manifolds, and fluid power components for mobile and industrial equipment. Directly comparable to Griner's fluid handling and construction-equipment precision parts.
• Cox Manufacturing Company: Long-standing US screw machine products manufacturer producing high-volume precision turned parts for automotive and industrial customers. Directly comparable in process mix (multi-spindle screw and CNC turning) and customer profile.
• Metalex Manufacturing: Mid-sized US precision machining shop producing turned and milled components for automotive, fluid power, and industrial customers using multi-spindle screw and CNC equipment — closely mirrors Griner's process stack.

Emerging players

• Tegra Medical: Medical device contract manufacturer specializing in precision machining and assembly for surgical instruments, implants, and diagnostics. Overlaps with Griner's medical segment and superfinishing capability.

Others

• Hydromat Inc. OEM of Hydromat rotary transfer machines — the same equipment platform Griner operates at scale. Highly relevant as an enabling supplier rather than a competitor, and a signal of where Griner's core technology comes from.
