What Sigma Engineering does

SIGMA Engineering GmbH is a German software company headquartered in Aachen that develops SIGMASOFT® Virtual Molding, a 3D injection molding simulation platform launched at the K 2013 trade show. The software performs coupled, multi-cycle 3D simulation of the complete injection molding process — including platens, cores, slides, ejectors, hot runners, and cooling channels with their physical material properties — using Navier-Stokes flow equations for filling and true 3D calculations for post-pressure and cooling phases. The platform is extended by specialized application modules covering thermoplast, elastomer, liquid silicone rubber (LSR), thermoset, compression molding, and metal/ceramic injection molding (MIM/CIM), plus add-on modules for autonomous optimization, collaborative results sharing (SIGMAinteract®), economic analysis (SIGMAecon), CAD integration (SIGMAcad), and downstream FEA export (SIGMAlink).

The company generates revenue through subscription-based licensing of the SIGMASOFT® software, supplemented by engineering consulting services (Virtual Thermoplastics, Engineering) and the Academy of Virtual Molding training program. Pricing is not publicly disclosed and is sold through direct enterprise field sales. SIGMA maintains wholly-owned regional subsidiaries in Germany (Aachen HQ), USA, Singapore, China, India, and Korea, with localized websites and language support serving major global plastics manufacturing clusters. The firm is a privately-held GmbH (HRB 7468, Aachen) operating as a subsidiary of MAGMA Gießereitechnologie GmbH, which also owns the SIGMASOFT and SIGMA trademarks; Thomas Klein serves as managing director. Headcount is reported at 11–50 employees, and the company has no disclosed external funding rounds. Customers include enterprise manufacturers and mold makers across automotive, electronics, optical components, silicone, rubber, and additive-manufactured tooling, with case studies reporting outcomes such as 90% concordance between simulated and measured distortion, 52% scrap reduction via virtual runner optimization, and 90% reduction in axial deformation of precision automotive gear wheels through virtual DoE.

Core offering

Sigma Engineering develops and licenses SIGMASOFT Virtual Molding, a 3D injection molding simulation software that models the complete mold (platens, cores, slides, ejectors, hot runners, cooling channels) with their physical material properties. The software performs multi-cycle analysis simulating transient heat transfer between melt, mold, and cooling systems to predict filling, packing, cooling, shrinkage, warpage, and part quality outcomes before physical production. Specialized modules extend coverage to thermoplastics, elastomers, liquid silicone rubber (LSR), thermosets, compression molding, and metal/ceramic injection molding (MIM/CIM).

Product overview

Sigma Engineering offers SIGMASOFT® as a unified simulation platform built around the core SIGMASOFT® Virtual Molding engine. The platform is extended by specialized application modules for different materials and processes — including Thermoplast, Elastomer, LSR (Silicone), Thermoset, Compression Molding, and MIM/CIM — as well as the Autonomous Optimization module (for automated DoE-based optimization), SIGMAinteract® (for collaborative results sharing), and SIGMAecon (for economic analysis). Connectivity add-ons include SIGMAlink (for exporting results to external FEA tools) and SIGMAcad (for CAD import). The portfolio also includes professional services (Virtual Thermoplastics, Engineering) and the Academy of Virtual Molding for training. The software is owned by MAGMA Gießereitechnologie GmbH and marketed under the SIGMA brand.

Emerging players

• Stratasys: Stratasys is a 3D printing leader whose simulation tools (e.g., GrabCAD Print, partner integrations) increasingly serve injection-molded plastics workflows, positioning it as an adjacent competitor in digital manufacturing for plastics.
• ESI Group: ESI Group provides virtual prototyping software for manufacturing processes including polymer and composite processing, positioning it as an adjacent simulation competitor serving similar industrial customers.

Direct peers

• Moldex3D: CoreTech System's Moldex3D is the most direct competitor to SIGMASOFT, offering 3D injection molding simulation for filling, packing, cooling, and warpage across thermoplastics, with overlapping application areas in automotive, electronics, and optics.
• CoreTech System Co., Ltd. CoreTech System is the parent company of Moldex3D and the most direct comparable to SIGMA as a focused Taiwanese/German competitor dedicated specifically to injection molding simulation technology.

Broad incumbents

• ANSYS: ANSYS (including Polyflow) is a broad multiphysics CAE platform with polymer flow and injection molding capabilities. While not a pure-play molding tool, it competes for enterprise CAE budgets in the same customer accounts as SIGMA.
• Dassault Systèmes (3DEXPERIENCE): Dassault's 3DEXPERIENCE platform offers plastic injection and manufacturing simulation within its broader PLM ecosystem, competing for enterprise simulation and design platform budgets alongside SIGMA's specialized tools.
• Siemens Digital Industries Software (Simcenter): Siemens' Simcenter platform includes mold-flow and plastics simulation tools integrated with NX CAD, competing with SIGMA on bundled CAD/CAE deals in large industrial enterprises.
• Hexagon (MSC Software): Hexagon (formerly MSC Software) provides manufacturing and engineering simulation software, including solutions used by plastics and automotive customers that overlap with SIGMA's injection molding use cases.
• Autodesk Moldflow: Autodesk's Moldflow is an incumbent injection molding simulation suite integrated into its broader CAD/CAE ecosystem (Fusion 360, Inventor), targeting the same plastics converter and mold designer customer base as SIGMA.

Others

• MAGMASOFT (MAGMA Gießereitechnologie): MAGMASOFT is the casting simulation software of SIGMA's parent company MAGMA. While focused on metal casting rather than plastics, it operates under the same Aachen-based ownership and shares technical heritage and customer overlap in advanced manufacturing simulation.
