When a tool isn’t running, production isn’t running.
That’s why we built a 24/5 staffed toolroom focused on keeping molds production ready.

If you’re dealing with a tool that:
-won’t hold tolerance,
-flashes, shorts, or sticks,
-can’t hit cycle time consistently, or “runs” — but only with constant babysitting…

…we can often take that transfer tool (when it’s the right fit) and turn it into a stable, production-ready mold through tooling expertise and disciplined process.

What makes the difference?
✅ Tooling resources available 24/5
✅ Deep troubleshooting + repair capability (not just “run it until it fails”)
✅ A culture of craftsmanship supported by our tool & die apprenticeship program — building the next generation of toolmakers while strengthening our shop every year
If you have a mold your current supplier is struggling to run, we’re happy to review it and tell you quickly whether it’s a fit.
Message us if you want to discuss a transfer tool situation.

Where Molded Parts Matter Most
Injection molding plays a critical role across industries where precision, durability, and consistency aren’t optional—they’re essential.
Here are just a few places it makes an impact:
🔷 Medical
The right manufacturer produces parts that are precise, durable, and consistent—key for medical components that support patient care and safety.
🔷 Building & Construction
From pipe and electrical fittings to window and door hardware, injection molded components deliver reliability where it counts.
🔷 Automotive
Once designs are dialed in, injection molding enables efficient, high-volume production of quality parts used across the automotive world.

If your parts need to perform without compromise, your molding partner matters.

The difference between a good part and a costly headache often comes down to one thing:

Who you trust to mold it.

If you’re evaluating injection molding partners—or questioning your current one—these questions are a great place to start.

When you’re ready to talk through your requirements, our team at JACO is always open to the conversation.

At Jaco, we are all personally committed to meet, and driven to exceed our customers' expectations, while continually improving our Quality Management System and satisfying applicable requirements.

Partnering with a supplier that has a robust quality system isn’t just about meeting specs — it’s about confidence.

Confidence that every measurement matters. Confidence that processes are documented, repeatable, and improving. Confidence that issues are prevented, not just corrected.

At Jaco, quality is never “done.” We continually evaluate, refine, and strengthen our Quality Management System so our customers can rely on consistent performance today — and even better results tomorrow.

If you’re looking for a partner who treats quality as a commitment, not a checkbox, let’s talk.

Every plastic part has a story behind it.
And usually… a lot of questions.

What material will hold up long-term?
How tight should the tolerances really be?
Will the tool run consistently at volume?
What happens when requirements change?

That’s where the right manufacturing partner matters.
We work alongside our customers to think through the details early, solve problems before they turn into delays, and engineer solutions that support production.

From design support and tooling to molding and ongoing production, our focus is simple:
make complex projects easier to manage and easier to scale.

If you’re looking for a team that asks the right questions, communicates clearly, and takes ownership from start to finish, we’d love to be part of your next project.

It’s easy to make good parts at startup. The challenge is making good parts thousands and eventually millions of cycles later.

The real test is running it day after day, month after month, year after year — while holding tolerances and keeping the process stable.

High‑volume molding demands more than machine capacity. It demands experience.

After 75+ years in plastics, we’ve learned that predictability comes from the details: tool condition, resin handling, controlled parameters, and disciplined, repeatable production habits.

If your part demand is growing, it’s worth choosing a partner built for long‑run consistency — not just output.

That’s why Jaco check valves are built for performance and trusted across both NPT (imperial) and BSPT (metric) applications.

What sets Jaco check valves apart:

• Zero leakage performance
• 100% tested before shipment
• 316 stainless steel ball & spring
• Viton O‑ring for excellent sealing
• PVDF construction for chemical and corrosion resistance
• Consistent cracking pressure (1–2.5 PSI)
• High temperature capability (180°F @ 220 PSI imperial / 82.22°C @ 220 PSI metric)
• Additional configurations available (Hastelloy springs, Teflon balls, specialty O‑rings)

If you’ve ever wondered how plastic parts take shape, here’s a simple step‑by‑step visual.

Injection molding can appear like a quick melt‑and‑shape process, but the real magic happens long before production starts.

Engineers carefully design the part geometry and validate how the material will flow and cool. Skilled toolmakers then build the precision mold that brings that design to life. Only after all of that work can the press run efficiently and reliably.

Here’s a quick look at the steps in the process once a mold is built and the part is ready for full‑production molding.

Businesses have been trusting Jaco for over 75 years with their plastic injection molding needs.
