What tennmax united does

TennMax America, Inc. is a privately held specialty manufacturer of EMI (electromagnetic interference) shielding and thermal management solutions for electronic and industrial applications. Founded over 20 years ago and headquartered in Vancouver, Washington, the company operates a multi-country manufacturing footprint spanning one US facility and four wholly-owned Asian subsidiaries in Taiwan (TennVac Technology Co., Ltd.), Shenzhen (TennVac Technology (Shenzhen) Co., Ltd.), Kunshan (TennMax Electronic Material (Kunshan) Co., Ltd.), and Zhongshan (TennVac Technology (Zhongshan) Co., Ltd.). The company serves customers in aerospace and defense, automotive and electric vehicles, medical devices, telecommunications, and industrial controls, and holds ISO 9001, AS 9100, ITAR, CMMC/SP NIST 800-171, and RoHS certifications.

TennMax's core product portfolio is built around six integrated technology lines: Vacuum Metallization (PVD) for depositing metallic coatings on plastic housings; Form-In-Place (FIP) dispensed conductive elastomer gaskets, including proprietary MaxEEC and MaxTEC combo materials; Thermal Interface Materials (gap filler pads and dispensable jellies); custom Thermal Modules and Assemblies with embedded heat pipes or water cooling cold plates; RF and Microwave Absorbers offered in dispensable epoxy, fluorosilicone, and silicone pad formats; and Turnkey/End-to-End Solutions that combine metal housing, FIP gasket, thermal module, and TIM into a single integrated assembly. The company's stated differentiator is vertical integration, offering PVD, FIP, RF absorbers, and thermal management under one roof, which is rare in the industry. TennMax's website also signals an ongoing facility relocation for its US headquarters.

TennMax operates on a B2B direct sales model targeting enterprise customers with custom-engineered requirements. Pricing is quote-based and not publicly disclosed, with quotes valid for 90 days, Net 30 payment terms, and FOB Factory/Ex-Works shipping. Revenue is generated from custom manufacturing orders plus one-time non-recurring engineering charges invoiced upon first shipment, with TennMax retaining ownership of production tooling and masks. The go-to-market motion is consultative and technical, with direct engagement with customer engineering teams, rapid prototyping, and content marketing through technical articles and product selection guides on the company website.

Core offering

TennMax United designs and manufactures EMI shielding and thermal management products, including vacuum metallization (PVD) coatings on plastic housings, form-in-place (FIP) conductive elastomer gaskets, thermal interface materials, thermal modules and heat sinks, RF and microwave absorbers, and turnkey end-to-end assemblies. Products are custom-engineered for aerospace and defense, automotive and electric vehicles, telecommunications infrastructure, medical devices, and industrial control applications. The company integrates PVD, FIP, RF absorber, and TIM production with downstream injection molding, machining, and assembly under one roof across US and Asian facilities.

Product overview

TennMax offers a unified portfolio of EMI shielding and thermal management solutions for mission-critical electronics across aerospace, automotive, telecommunications, and medical industries. The core offerings include: Vacuum Metallization (PVD) for applying metallic coatings to plastic housings; Form-In-Place (FIP) Gaskets for automated dispensed conductive elastomer seals; Thermal Interface Materials (TIM) including gap filler pads and dispensable jellies; Thermal Modules & Assembly for custom thermal management design; RF & Microwave Absorbers for signal absorption; and Turnkey/End-to-End Solutions integrating multiple technologies into comprehensive assemblies. The company's differentiation lies in its vertically integrated approach, combining vacuum metallization with FIP gaskets and RF absorbers under one roof—a rare capability in the industry—enabling customers to source complete shielding and thermal management solutions from a single partner.

Products and services

• Vacuum Metallization (PVD) Physical Vapor Deposition process that deposits metallic layers (including Cu/Ni, Cu/Cr, Cu/NiCr, Cu/Ti, Cu/SS, Cu/SiO2, Cu/Ag, Cu/Al, Cu/Sn, Cu/AF, Pure Al, Pure Ag) on non-metallic substrates for cost-effective EMI shielding of plastic housings. Used by aerospace, defense, automotive, telecom, and medical electronics manufacturers seeking lightweight alternatives to metal enclosures.
• Form-In-Place (FIP) Gaskets Automated dispensing of conductive elastomer gaskets on metal or plastic housings with pinpoint four-axis accuracy, achieving beads as small as 0.3mm. Includes EMI shielding gaskets with nickel/graphite fillers, environmental sealing gaskets, and combo materials MaxEEC and MaxTEC for integrated shielding and thermal performance.
• Thermal Interface Materials (TIM) Thermally conductive gap filler pads and dispensable silicone and non-silicone jellies engineered for thermal transfer between surfaces such as microprocessors and heat sinks. Includes GP-series thermally conductive pads, T-CIP-series dispensable jellies, and GPF-series products for thermal management in power-dense electronics.
• Thermal Modules and Assembly Custom thermal management designs for early-stage product development, using thermal software simulation to create heat sinks with embedded heat pipes or water-cooling cold plates. Provides assembled thermal modules tailored to specific power and form-factor requirements.
• RF and Microwave Absorbers RF absorbing materials supplied as automated dispensing epoxies and cavity resonance pads, including CR-DE dispensable epoxy, CR-DFS dispensable fluorosilicone, and CR-SS silicone absorber pad formats. Designed for cavity resonance and standing wave suppression with low outgassing properties; epoxy absorbers meet NASA outgassing requirements and cavity resonance pads are RoHS-compliant and halogen-free.
• Turnkey / End-to-End Solutions Comprehensive integrated assembly combining metal housing, form-in-place EMI gasket, thermal module, and thermal interface material into a single advanced functional gasket with reliable environmental seals.
