Plastic Part Manufacturing in Chicago, IL
Accurate Products Inc. manufactures precision plastic parts for OEM and industrial distribution customers from its Chicago, IL facility at 4645 N. Ravenswood Ave. With over 65 years in operation and more than 50,000,000 standard parts sold last year, the company supports prototype through high-volume production runs using injection molding, die cutting, extrusion, and compression molding — all under one ISO-certified roof.
What Plastic Materials Does Accurate Products Work With?
Material selection determines part performance. Accurate Products manufactures components using thermoplastics and engineered resins chosen to match application requirements for strength, wear resistance, chemical exposure, and operating temperature. Commonly processed materials include ABS, polycarbonate (PC), polypropylene (PP), HDPE, nylon (PA66), acetal (POM/Delrin), PEEK, PVC, and TPE. For structural or high-load applications, glass-filled variants of nylon and polypropylene offer tighter dimensional control and reduced thermal drift — a critical factor when replacing metal components with plastic.
Process Capabilities: How Accurate Products Manufactures Plastic Parts
Each part design dictates the best production method. Accurate Products operates multiple plastic manufacturing processes from its Chicago facility.
Injection Molding
The most common process for high-volume plastic parts. Molten resin is injected into a steel or aluminum tool under pressure, then cooled and ejected. Typical tolerances range from ±0.005 to ±0.020 inches depending on resin and geometry. Accurate Products produces both standard catalog parts and custom-tooled components via injection molding.
Die Cutting
Ideal for flat plastic sheet components requiring precise, repeatable shapes. Accurate Products uses steel-rule and hard dies to cut profiles from sheet stock — common in gasket blanks, isolator pads, and protective inserts. Die cutting suits both small prototype quantities and large production volumes.
Extrusion and Compression Molding
Continuous plastic profiles — seals, edge trim, and tubing — are produced via extrusion. Compression molding handles thermoset and specialty resins where injection tooling costs are not justified. Both processes run out of the same Chicago plant, simplifying vendor management for multi-process programs.
Tolerances and Quality Standards for Plastic Parts
Tolerance capability depends on material, process, and geometry. For injection-molded acetal and PEEK parts, Accurate Products targets ±0.001 to ±0.005 inches on critical dimensions. ABS and polycarbonate components typically hold ±0.005 to ±0.010 inches. Softer materials like HDPE or PP require looser allowances to account for thermal expansion and shrink variation. Accurate Products is ISO-certified in the United States and TS-certified in China, providing a documented quality system behind every production run. Dimensional inspection is part of standard production — not an add-on.
Plastic vs. Rubber Manufacturing: Which Does Your Application Need?
Both materials are available from Accurate Products, and the right choice depends on the operating environment, not preference. Plastic parts — rigid, lightweight, and corrosion-resistant — suit applications requiring dimensional precision, electrical insulation, or cost-effective high-volume output. Cycle times for plastic injection molding are measured in seconds, which drives down per-piece cost at scale. Rubber parts, by contrast, excel where flexibility, vibration damping, dynamic sealing, or extreme-temperature exposure is required. Vulcanized rubber maintains shape across a wider temperature range than most thermoplastics. For programs requiring both material types — a bumper with an overmolded rubber face, for example — Accurate Products handles both from a single Chicago facility, eliminating split-vendor coordination.
Industries Served by Accurate Products Plastic Part Manufacturing
Accurate Products ships plastic components to OEM and MRO customers across multiple sectors. Current industry applications include automotive brake aftermarket (bumpers, grommets, isolators), HVAC and heating equipment (seals, extrusions, vibration mounts), commercial electronics and wiring (protective grommets, cable management parts), medical device manufacturing (precision molded components), gaming and recreational equipment, train and rail (vibration control, protective parts), and printing and paper handling (suction cups, roller components). Standard stocked parts typically ship within 48 hours from the Chicago warehouse. Custom parts are quoted based on drawing, sample, or performance specification.
Why Chicago Manufacturers Choose Accurate Products
Location matters for fast-turnaround programs. Operating from Chicago’s North Side since the company’s founding, Accurate Products serves industrial customers across the Chicago metro without adding freight days or minimum-order freight penalties common with out-of-state suppliers. The facility holds the largest variety of standard molded sizes and shapes in the U.S., with most stock items available for same-week shipment. For custom programs, the team works from customer drawings, CAD files, or physical samples. Just-in-Time (JIT) shipping arrangements are available for ongoing production programs.

Frequently Asked Questions
What types of plastic parts does Accurate Products manufacture?
Accurate Products manufactures bumpers, grommets, seals, gaskets, extrusions, suction cups, and custom-engineered components using thermoplastics and engineered resins including ABS, nylon, acetal, PEEK, HDPE, PP, PC, PVC, and TPE.
What tolerances can Accurate Products hold on plastic injection-molded parts?
Typical tolerances range from ±0.001 to ±0.020 inches depending on material and geometry. Acetal and PEEK hold the tightest tolerances; softer materials like HDPE or PP require more generous allowances to account for thermal expansion and shrink rate.
Does Accurate Products manufacture both plastic and rubber parts?
Yes. Accurate Products produces both plastic and rubber components from its Chicago, IL facility. Customers can source both material types from one supplier, which reduces purchasing complexity and simplifies project coordination.
What is the minimum order quantity for plastic parts?
Minimum order quantities vary by part type, material, and whether the part is standard or custom. Contact the team at (773) 878-2200 or sales@accurate-prod.com for specific quantities relevant to your project.
Does Accurate Products ship plastic parts outside of Chicago?
Yes. Accurate Products ships rubber and plastic products nationwide from Chicago, IL. International shipping is available on request, and Just-in-Time delivery arrangements can be made for ongoing production programs.
