Injection Molding Tip:

𝐖𝐡𝐲 𝐔𝐧𝐢𝐟𝐨𝐫𝐦 𝐖𝐚𝐥𝐥 𝐓𝐡𝐢𝐜𝐤𝐧𝐞𝐬𝐬 𝐌𝐚𝐭𝐭𝐞𝐫𝐬

When designing a plastic part, it can be tempting to add material wherever additional strength is needed.

But thicker isn't always better.

Significant wall thickness variations can contribute to:

• Sink marks
• Warpage
• Longer cooling times
• Increased cycle times
• Dimensional variation

In many applications, designers can achieve the required strength through properly designed ribs and gussets rather than simply increasing wall thickness.

Good part design isn't just about creating a functional part.

It's about creating a part that can be produced consistently and efficiently.

A well-designed part can help support better quality, lower manufacturing costs, and more repeatable production.

At Jaco, we enjoy working with customers early in the design process to help identify opportunities that can improve manufacturability while supporting application requirements.

JACO compression tube fittings have built a strong reputation of their own over the years.

They are trusted across a wide range of tubing applications where fit, function, material performance, and reliability matter.

But not every application fits neatly into a standard catalog size or configuration.

That is where custom support can make a difference.

We have worked with customers to develop custom JACO-style compression fittings for their specific applications — keeping the proven JACO compression nut design on one end while creating tooling for the thread, geometry, or connection style needed on the other.

This allows customers to benefit from the familiar JACO compression fitting design while getting a part better suited for their specific system.

These types of custom fitting solutions are where our product experience and custom molding capabilities come together.

If your application requires something beyond a standard fitting, we would be happy to review it with you and see where we may be able to help build the right solution.

Standard products solve a lot of problems.

But sometimes the right solution requires taking what already works and adapting it to the customer’s application.

Reliable connections shouldn't be something you have to think about.

That's exactly the point.

Molten plastic gets pushed into a precision steel mold, cools into shape, and pops out as a finished part. It’s a simple process on the surface and may even look simple at first glance. The fact is, it takes careful decision‑making, expertise, and dedication to go from just an idea to full production and make the parts right.
There’s something interesting about watching raw material turn into a part you can actually hold — especially at production‑level volume and efficiency, where these machines can run millions of parts.

Some supply chain risks are obvious.

Others do not show up until a part is late, a tool needs attention, or communication slows down when production needs to keep moving.

For molded plastic components, having the right supplier support in place can make a real difference.

That might mean reviewing an existing tool.
It might mean qualifying a second source.
It might mean moving a program closer to home.
Or it might simply mean having a manufacturer ready to help when needs change.

At Jaco, we support custom injection molding programs, transfer tools, and long-term production needs from our facility in Berea, Ohio.

For customers with critical molded parts, the value is not just in making the part.

It is in helping reduce risk, improve communication, and keep programs moving.

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.
👉 Let’s talk about your next project.

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.
