ISO 9001 & AS9100D certified precision plastic injection molding for medical, aerospace, pharmaceutical, and industrial applications. American-made quality, boutique precision, personal service.
While large offshore competitors struggle with communication, lead times, and accountability — Comet Tool Company delivers personal service, American-made quality, and the certifications your regulated-industry project demands.
We stand behind every tool and part with a full 12-month warranty — longer than any competitor. Our confidence comes from our craftsmanship.
In-stock mold frames and a streamlined DFM process mean your tool is qualified and producing parts faster than overseas alternatives — without the risk.
ISO 9001:2015 and AS9100 Rev D certified. When your application is medical, aerospace, or pharmaceutical, certification isn't optional — it's the baseline.
From design support and mold build to injection molding, assembly, and packaging — Comet Tool Company manages your entire program so you manage one partner, not five.
High-volume and precision low-volume production across a full range of engineering resins — from commodity plastics to high-performance polymers.
In-house tool design and fabrication with a 12-month warranty on all tooling. We build molds that last — single-cavity to complex multi-cavity configurations.
Our engineers review your designs for manufacturability before a single chip is cut — reducing tooling cost, cycle time, and first-article failures.
100% inspection capability, PPAP documentation, SPC charting, and full traceability — essential for FDA-regulated, aerospace, and defense programs.
We handle sourcing, sub-assembly, and secondary operations so you receive a finished product — not a component requiring more work downstream.
PEEK, Ultem, Nylon, Acetal, Polysulfone — we process a wide range of engineering and specialty resins for the most demanding application requirements.
Founded in 1983 in Pitman, New Jersey, Comet Tool Company has grown from a regional mold maker into a full-service precision injection molding partner trusted by engineers designing components where zero failures are acceptable.
We're not the largest. We're the most precise — and our customers in the medical, aerospace, and pharmaceutical sectors choose us for exactly that reason.

Our engineers design the optimal mold — balancing part quality, cycle time, and tool longevity.
Precision CNC machining and EDM produce a mold built to our exacting in-house standards.
T1 samples are measured, documented, and submitted for your approval with full PPAP package.
Approved tools enter production with SPC monitoring, 100% inspection, and on-time delivery.

FDA-compliant components for diagnostic, surgical, and drug delivery applications.

Closures, dispensing systems, and packaging components for pharma manufacturers.

Mission-critical plastic components where first-time quality is non-negotiable.

Enclosures, housings, and connector components for demanding electronic applications.

Precision plastic housings and structural components for telecom infrastructure.

Child-resistant, tamper-evident, and specialty closures for consumer and industrial products.
Comet Tool Company has been our sole source for surgical instrument housings for over eight years. Their AS9100-backed quality process and zero-defect track record give us confidence that no offshore supplier ever could.
We moved our closure program to Comet Tool Company after quality issues with a larger supplier. Their DFM team caught wall-thickness issues that would have cost us six figures in rework. They've been a true engineering partner.
AS9100D certification was the baseline — but Comet Tool Company's responsiveness is what keeps us coming back. Prototype to production in weeks, not months. For defense subcontract work, that speed is a competitive advantage.
