Lomont Molding

What Lomont Molding does

Lomont Molding LLC is a privately-held custom plastic molder founded in 1982 and headquartered in Mount Pleasant, Iowa, operating as a top-100 North American injection molder with 251-500 employees. The company runs six in-house molding competencies — injection molding, blow molding, structural foam, over-molding, nitrogen gas-assist molding, and in-mold decorating — supported by an in-house tool room, IQMS ERP-driven traceability, robotics automation, full secondary operations (sonic welding, hot stamping, painting, assembly, kitting), and engineering services spanning SOLIDWORKS/KeyCreator/Mastercam CAD, mold flow simulation, and rapid prototyping via CNC, RTV silicone, and 3D printing. Press capacity ranges from 30 to 2,700 tons following a 2025 facility expansion.

The company operates three proprietary sub-brands alongside its core molding services: Lomont IMT (In-Mold Technologies), which leverages a patented In-Mold Decorating process to produce durable industrial tags, OSHA/ANSI/GHS-compliant safety signage, and metal/X-ray detectable products for food-safety environments; Paragon Products, supplying concrete and rebar accessories to the highway, ready-mix, precast, and test-lab markets; and R&D Molders Canteens, a legacy blow-molded military-grade canteen line acquired in 2017. A second warehouse/distribution footprint in Texas supports blow molding operations serving medical, consumer, electronics, and energy end markets.

Lomont generates revenue through enterprise field sales using an Early Supplier Development engagement model — embedding engineers at the OEM design phase to drive design-for-manufacturability, tooling risk reduction, and accelerated timelines — supplemented by a quote-based Request a Quote system. Named enterprise customers span Trane, Hussmann, Thermo-King, Ingersoll Rand, EcoLab, Kinze, Sears Manufacturing, Tennant, and Leprino Foods across HVAC, refrigeration, transportation, industrial, cleaning, agriculture, and food processing verticals. Lomont IMT additionally operates a self-serve webstore with Pick & Pack fulfillment for repeat industrial tag and safety signage orders. The company is ISO 9001:2015 certified, holds no external private equity backing, and is led by CEO, President and Board Member Jason Bender alongside founder Jerry Schimmelpfennig.

Products and services

• Injection Molding High-pressure plastic injection molding producing complex, precise thermoplastic parts with consistent quality and repeatability for production runs of any size, served by ISO 9001 certified presses up to 2,700 tons.
• Blow Molding Custom blow molding of hollow plastic components and containers using continuous, accumulating head, and reciprocating screw configurations, supporting up to 7-pound shot sizes and 4-cavity designs for medical, consumer, electronics, and energy markets.
• Structural Foam Molding Low-pressure molding process producing lightweight, rigid parts with a solid outer shell and cellular foam core, providing high strength-to-weight ratios, impact resistance, and cost savings on large, thick-walled components.
• Over-Molding Injection molding process where TPE or other plastics are molded onto rigid plastic substrates using heat, pressure, and silicone to create strong bonds without primers or adhesives, enabling multi-material designs with soft-touch or protective overlays.
• Nitrogen Gas-Assist Molding Low-pressure injection molding using pressurized nitrogen to form hollow sections inside thick areas, displacing material to reduce part weight while maintaining structural integrity; eliminates sink marks and warp and enables faster cycle times.
• In-Mold Decorating (IMD) Patented process that integrates vibrant, durable graphics directly into molded parts by placing a printed film or label into the mold cavity before injection, creating tamper-proof, fade-proof branding with metallic finishes, gradients, textures, and transparent overlays.
• Assembly and Secondary Operations In-house post-molding services including sonic welding, hot stamping, insert loading, post-production forming, date coding, labeling, custom packaging, and a full paint line with booth for high-volume and precision painting.
• Tooling Services In-house toolroom services for tool management, maintenance, repairs, and engineering changes, including advanced machining, polishing, and EDM capabilities for preventative maintenance and full tool repairs, supporting presses from 30 to 2,700 tons.
• Engineering and Robotics Services In-house engineering and automation capabilities including CAD/CAM/CAE design with SOLIDWORKS, KeyCreator, and Mastercam, mold flow simulation, rapid prototyping via CNC machining, RTV silicone molding, and 3D printing, plus automated insert loading, pick-and-place, snap lids, label application, and tray loading.
• Early Supplier Development Design for Manufacturability (DFM) guidance, material selection consulting, mold-flow simulation, prototyping, and tooling risk reduction services delivered through Early Supplier Development engagement starting at the design or pre-tooling phase.
• Lomont IMT Safety Signage and Industrial Tags Proprietary brand line of advanced safety signage and identification products using patented In-Mold Technology, including custom-molded industrial tags for chemical ID, process labeling, and asset tracking, OSHA/ANSI Z535/GHS-compliant safety signs, and metal/X-ray detectable products for HACCP/FSMA food-safety compliance.
• Paragon Products (Concrete and Rebar Accessories) Proprietary brand of concrete and rebar accessories including hole covers, cable caps, and rebar supports serving the commercial highway, concrete test lab, Ready-Mix, and pre-cast construction markets.
• R&D Molders Canteens Rugged, field-tested blow-molded plastic canteens originally developed for military, government, and field-use applications, now produced exclusively by Lomont Molding.
