What Chemtech Plastics does

Chemtech Plastics, Inc. is a privately held US precision injection molding company headquartered in Elgin, Illinois, founded in 1982 by Ragnar Korthase. The company operates a single 135,000 sq. ft. combined manufacturing and warehouse footprint with 54 injection molding machines, a 24/5 production schedule, two inspection and metrology labs, and a workforce of 300+ spanning engineering, tooling, automation, quality, and project management. It is DQS-certified to IATF 16949:2016 and ISO 9001:2015.

The company's technical offering centers on tight-tolerance precision molding, including straight molding, insert molding, 2K/3K multi-shot molding, overmolding, and in-mold assembly, supported by in-house precision toolmaking with a 1 million shot warranty, Moldex3D CAE simulation on every new program, APQP-based program management, certified Master Molders, and an in-house automation team. The equipment base includes TOYO Si-6/Si-7, ARBURG Allrounder 520 S, and Sodick GL 150 machines, with Zeiss ATOS Q blue-light scanning for mold qualification. Documented tolerances reach 0.0001 inch on junction relay box inserts.

Chemtech generates revenue through quote-based custom manufacturing contracts across four primary verticals: automotive (named customers Hella, BCS, Sumitomo, ZF), medical (Swiss Precision Machining, with capacity for ~40M parts/year on automated lines), industrial electronics, and optical lighting, the last relying on a proprietary runner and gating technique for clear plastics. Go-to-market is enterprise B2B with dedicated project managers per account, DFM-driven early-supplier involvement, and multi-year program relationships. No external funding, M&A, or geographic expansion is disclosed.

Emerging players

• Protolabs: Digital manufacturing platform offering rapid injection molding (including multi-shot) for low-volume and prototyping work; competes with Chemtech on speed and on-demand quoting but lacks Chemtech's dedicated high-volume production and toolmaking depth.

Direct peers

• Mack Molding: Vertically integrated custom molder combining tooling, molding, and assembly for medical and industrial customers; comparable to Chemtech's single-source, in-house toolmaking-plus-production model.
• R&D Plastics: Custom injection molder focused on precision, short-run, and engineered-material work for industrial and electronics customers; comparable in technical molding niche and toolroom integration.
• Plastic Molded Concepts (PMC): Custom injection molder specializing in insert molding, multi-shot, and tight-tolerance components for industrial and electronics OEMs — closely aligned with Chemtech's technical molding and insert/overmolding capabilities.
• D&M Plastics: Mid-market custom injection molder serving automotive, industrial, and consumer OEMs with a similar vertical mix to Chemtech and comparable in-house tooling and assembly offering.
• EVCO Plastics: Large US custom injection molder serving medical, industrial, and consumer end-markets with in-house tooling, automation, and multi-shot capabilities — directly comparable in scope, customer mix, and value proposition to Chemtech.
• Tessy Plastics: Mid-to-large custom injection molder with strong medical device franchise and high-volume automated assembly; comparable to Chemtech in medical regulatory capability, automated throughput, and tier-1 OEM customer profile.
• Medbio: Medical-focused precision injection molder with cleanroom molding and assembly, serving Class I–III device OEMs; comparable to Chemtech's medical segment in regulatory, tolerance, and program management depth.
• Matrix Tooling & Molding: US-based custom injection molder with in-house tool design/build and tight-tolerance expertise for automotive and industrial customers — directly comparable in toolmaking-plus-molding integration.

Broad incumbents

• Phillips Medisize: Much larger global contract manufacturer with extensive medical device molding/assembly footprint; competes with Chemtech in medical molding and finished device assembly but at materially greater scale and geographic reach.
