Elk Grove, IL JBC - Chicago Formerly HST Materials, Inc.

JBC-Chicago – formerly HST Materials – is an ISO 9001:2015 certified material converter and precision die-cutting specialist with over 35 years in business. JBC-Chicago manufactures high-quality custom die-cut parts from a wide variety of thin, flexible materials for hundreds of customers and industry applications that range from automotive interiors and lighting to food service and consumer electronics.

JBC-Chicago offers various converting options, as well as a selection of value-added services that include custom packaging, bar-coding, and kitting. So whether you’re looking for rapid-turnaround prototypes, precision mass production of single or multi-layer die-cut parts, or tight-tolerance slit rolls of adhesive-backed foam, JBC-Chicago has you covered.

As part of the JBC Technologies network, we have the support and backing of an organization with manufacturing and inventory facilities in four states. 

As part of the JBC Technologies group, we specialize in converting flexible materials and the precision die-cutting of custom components from engineered materials like silicone sponge and PORON® urethane.

Our customers represent manufacturers all over the world, and the impact of what we do extends far beyond die-cut parts.

JBC-Chicago not only delivers high-quality, custom die-cut solutions, but we also offer supply chain and engineering innovations, manufacturing excellence, and solid industry partnerships to help our customers succeed.

Leading Manufacturers Look to JBC-Chicago for

Quick-Turnaround Prototyping Rapid Response

Using our Atom Flashcut dieless knife-cutting table and customer-supplied 2D CAD files, we can cut even relatively complex parts – with dimensions up to 4.8ft x 9.8ft (1.5m x 3m) - from a wide variety of thin, flexible materials.

We can often provide same-day turnaround on plastic films and adhesive tape parts.

  • Multi-Depth cutting of foams up to 5” (12.7-cm) thick
  • Routing
  • Kiss-cutting/Creasing
  • Punching
  • Drag KnifeMarking

High-Speed Rotary Precision Die-Cutting Flatbed/Platen

Our diverse selection of die-cutting presses lets us offer our customers die-cut parts made from one of the industry’s largest selections of non-metallic, flexible materials.

We can typically make your custom die-cut parts directly from your CAD files or part prints.

  • Servo-driven CNC stamping
  • State-of-the-art high-speed rotary die-cutting
  • Wide-web die-cutting of large-format parts
  • Traveling head die-cutting
  • Dieless cutting and rapid prototyping


Specialty Converting Spooling, Slitting & Laminating Thin, Flexible Materials

JBC-Chicago offers in- and offline lamination, slitting, and spooling of a wide selection of thin, flexible materials, including foam rubber and double-sided, single-sided & transfer adhesive tapes.

We can combine multiple rolls into single long-length spools to help reduce machine stoppage and increase efficiency and laminate adhesive tape to most common materials.

  • Slit to widths from 0.079in – 60in (2mm to 1,524mm)
  • FEBA, Rewind Slitting, and rotary gang knife slitting
  • Traverse-level wound spools of foam tape

Performance Material Testing Services Inspection

Making quality parts doesn’t stop at the die-cutting press. We use the latest automated inspection and performance testing equipment to perform mission-critical measurement and quality functions like

First-article Inspection • pK Studies • Gage Repeatability and Reproducibility (GR&R)

  • 90° and 180° peel adhesion tests
  • MicroVu Excel
  • Multiple substrate options
  • Precision-controlled laboratory-grade ovens
  • Adhesive force peel tester

Extruded Rubber Gaskets

We provide the highest quality extruded rubber profiles in sponge and dense rubber compounds through our partners Cooper Standard (formerly Lauren Manufacturing) and Clean Seal.

We can supply your extruded profile vulcanized, laminated with pressure-sensitive adhesive tape, die-cut, or fabricated as required for your exact application.
