MASS

What MASS does

MASS GmbH, founded in 1987 and headquartered in Anröchte, Germany, designs and manufactures customized special-purpose machines for printed circuit board (PCB) production and thermal process engineering. The company operates across two core technology areas: vacuum plugging systems for PCB manufacturing — including the vertical VCP/VCPM+ vacuum chamber systems and the horizontal VHF vacuum via hole filling machines — and thermal process systems such as paternoster dryers (PD), magazine continuous dryers (MT), horizontal stack dryers, vertical dryers, and hot-wall furnaces (HWF) reaching up to 1600°C. Supporting the core product lines are complementary modules including lacquer casting machines, wet grinding systems, paste recycling units, cleaning devices, cooling modules, and flash-off systems, all engineered for integration into customer production lines with MES connectivity.

MASS sells predominantly to enterprise buyers in PCB manufacturing, automotive, defense and aerospace, fuel cell, battery, and thin-film solar verticals, with stated deployments in leading European and international defense, aerospace, and high-end electronics programs. The business model combines one-off capital equipment sales (quote-based, multi-year contracts for bespoke machines), a recurring after-sales service and spare-parts revenue stream supported by a 24/7 worldwide hotline, and a contract manufacturing service ('Lohnplugging') offered in partnership with Hofstetter. Go-to-market relies on direct enterprise field sales, technical consultation, an on-site Demo Center, webinars, trade fair presence (notably Productronica 2025), and channel partnerships (Adeon Technologies, Allog Engineering, Oktopuls).

Effective April 1, 2026, MASS GmbH's business operations were transferred to publicly-listed SINGULUS TECHNOLOGIES AG (Frankfurt ticker: SING), making MASS a wholly-owned subsidiary. The company is led by Executive Board members Markus Ehret and Lars Lieberwirth, and was originally co-founded by Dietmar Hellmold and Franz Klocke.

Revenue model

1. Capital Equipment Sales: MASS generates primary revenue from the design, manufacture, and sale of specialized capital equipment including vacuum plugging systems (VCP/VCPM+/VHF), thermal process systems (paternoster dryers, hot-wall furnaces), lacquer casting machines, and handling systems. These are customized machines sold as one-offs or small series to industrial manufacturers worldwide.
2. Contract Manufacturing / Plugging Service: MASS offers PCB plugging as a service ('Lohnplugging') in partnership with Hofstetter, allowing customers to outsource production peaks or process development without purchasing equipment.
3. After-Sales Service, Maintenance & Spare Parts: MASS operates a 24/7 worldwide service hotline and sells spare parts. Remote maintenance and online support are offered as part of the after-sales service ecosystem.

Core offering

MASS designs, manufactures, and sells customized capital equipment for printed circuit board (PCB) production, centered on vacuum chamber plugging systems (VCP, VCPM+, VHF) for bubble-free via filling and thermal process systems (paternoster dryers, magazine dryers, hot-wall furnaces up to 1600°C) for drying, curing, brazing, and sintering. The company also offers lacquer casting machines for solder resist coating, automated handling equipment with MES integration, and a contract PCB plugging service (Lohnplugging) in partnership with Hofstetter. All equipment is custom-built at the Anröchte, Germany facility.

Product overview

MASS develops and manufactures customized thermal process systems and machines for printed circuit board (PCB) manufacturing. The product portfolio centers on two core technology areas: (1) Vacuum plugging systems for PCB manufacturing, including the VCP vertical vacuum chamber plugging system and VHF horizontal vacuum via hole filling machine, plus associated equipment like lacquer casting machines (LC), wet grinding (SV 200 WV), paste recycling (PRS), and cleaning units (RE); and (2) Thermal processing systems including paternoster dryers (PD), magazine continuous dryers (MT), horizontal stack dryers (HST 200), vertical dryers (VDH), and hot wall furnaces (HWF) up to 1600°C. Additional offerings include cooling modules (KMQ 200), flash-off systems (ABL 30), and PCB plugging contract services. MASS also provides complete automation and MES integration, and has opened a Demo Center for process testing and validation. The company operates from Anröchte, Germany, and transferred business operations to SINGULUS TECHNOLOGIES AG effective April 1, 2026.
