What Poplar Hill Machine does
Poplar Hill Machine, Inc. is a privately held precision CNC machining contract manufacturer founded in 2004 and headquartered in an 8,000 square foot AS9100D- and ISO 9001:2015-certified facility in Conway, Massachusetts. The company employs 16 highly skilled machinists plus a small named management team led by founder/President Michael Kurkulonis. Its core service is tight-tolerance, prototype-to-production CNC machining — run sizes from a single piece to tens of thousands — with a primary specialization in the Microwave RF industry, where components require micro end mills and tooling expertise. The customer base spans at least eight verticals: Microwave RF, Aerospace, Spectral Analysis, Medical, Alternative Energy, Shock Resistant Hardware, Optical and Ultrasound Imaging, and Firearms, with no named end-customer logos publicly disclosed.
The underlying technology platform is a multi-axis CNC fleet anchored by a Makino a51nx horizontal machining center, a Mori-Seiki NTX1000 SZM 11-axis/5-axis mill-turn, a Mori-Seiki NH4000 DCG HMC, an Okuma Space Center MA-400HA HMC with a 12-pallet pool, an Enshu GE580H, Brother Speedio R650X2, a Doosan DNM500II, a Brother TC-32BN QT, and a Star Lathe. CAM programming runs on Mastercam 2023 with UltraEdit/UltraCompare, and the firm accepts a broad range of 3D and 2D CAD formats (SolidWorks 2023, STEP, Parasolid 34, ACIS 2021, Solid Edge 2023, SpaceClaim 2022, Alibre V24, KeyCreator 2011, Rhino 5, AutoCAD 2024). In-house quality assurance is built around a Sheffield Discovery III D-8 coordinate measuring machine plus Brown & Sharpe, Mitutoyo, and Fowler digital height gauges and a Mitutoyo PH-3500 projector. Secondary operations include sawing, tumbling, ultrasonic cleaning, parts washing, and Telesis TMP 3000 pinstamping.
The business model is a direct, quote-based contract manufacturing service. Pricing is not publicly disclosed; customers submit specifications through a website Request-for-a-Quote form or by phone (413-369-4252) and receive a custom estimate from General Manager/Estimator Steve Dacyczyn. CAGE Code 4A5S1 enables U.S. federal and defense contract eligibility, and AS9100D/ISO 9001:2015 certification supports aerospace supply-chain revenue. The shop runs 'lights out' through nights and weekends to meet customer delivery schedules, and the firm is a privately controlled, owner-operated business with no disclosed institutional investors, subsidiaries, parent entities, or M&A activity.

- Hubs: Hubs (now part of the Protolabs Network) provides instant online quoting for CNC machining and other custom manufacturing services. It is a direct peer to PHM in the prototype and short-run precision machining segment.
Broad incumbents
- Precision Castparts Corp: Precision Castparts (a Berkshire Hathaway subsidiary) is a large diversified manufacturer of complex metal components and assemblies for aerospace and industrial markets. It overlaps with PHM as a precision components supplier to aerospace OEMs, but at vastly larger scale and broader product portfolio.
- Howmet Aerospace: Howmet Aerospace is a large global supplier of engineered aerospace components, including precision machined and finished parts. It is comparable to PHM as a precision aerospace components supplier, but operates at much greater scale and across a far broader product range.
Emerging players
- Plethora: Plethora (now part of the Protolabs Network) provides on-demand CNC machining and other fabrication services with software-driven quoting. It is comparable to PHM as a digitally-enabled custom machining supplier targeting industrial buyers.
