Custom injection molding since 1972

We make the parts nobody thinks about.

Small-to-mid plastic parts and assemblies — made right, made responsive. The screen key in your window, the latch in your RV door, the spacer your guitar hangs on. Somebody has to make those. For over 50 years, that's been us.

The whole idea

We'll take care of it.

It's the sign on our wall, and it's the reason customers stay. In an industry where nobody picks up the phone, we do. Here's what that means for you:

We answer

Real people, same day. Call us in an emergency and we make it happen.

We stock for you

We keep partials and hardware on hand — so a supply crunch doesn't stop your line.

We save the regrind

We reuse your regrind instead of throwing it away — and that saves you money.

Fair price, first time

You get our best price up front — no gouging, no games. That's been the rule since day one.

What we make

The small plastic parts that hold bigger things together.

From a few thousand pieces to a few million a year — in nylon, styrene, acetal, polycarbonate, polypropylene, and PVC.

Window & screen keys

Radius and corner keys by the million — our styrene workhorse.

Weep plugs & covers

PVC plugs that keep the rain out of every extrusion — we make millions.

Egress & latch handles

Full assemblies — handle, catch, keeper — built and kitted in-house.

Housings & mounts

Detector housings, TV hangers, instrument mounts — the parts you never notice.

Spacers & small parts

The unglamorous pieces, in the right material, at the right tolerance.

Built assemblies & kits

Rivets, springs, foam, wool pile — assembled, bagged, and ready to install.

Industries we serve

We know your parts because we've been making them for decades.

Capabilities at a glance

Right-sized for the work that needs a real partner.

We're built for small-to-mid parts, honest tolerances, and runs from a few thousand to a few million. Not the biggest shop — the most responsive one.

Are we the right shop for your part?

We're a great fit for loose-to-moderate tolerance plastic parts and assemblies. We're not a medical or tight-tolerance house — and we'll tell you straight if your part belongs somewhere else. That honesty is why our customers trust us with everything else.

Why it matters

When the supply chain broke, we didn't.

In 2020 and 2021, builders couldn't get parts because their molders couldn't get hardware. We could — because we keep months of it on hand. We didn't just keep up. We gained business, and we kept every promise we made.

The shop

The people who'll take care of it.

A small, cross-trained crew — so someone always knows your parts, and someone always picks up. When you call Security Molding, you're talking to one of them, not a call center.
