Custom Metal Components: Precision Solutions for Modern Manufacturing

Custom metal components are the foundation of innovation. They power machines, enable technology, and help shape industries. From aerospace to electronics, precise and reliable parts are essential. That’s where TMN Etch steps in.

We specialize in photochemical etching—a process that transforms flat metal sheets into detailed, high-performance components. We serve clients who demand quality, speed, and accuracy. And we deliver every time.

What Are Custom Metal Components?

Custom metal components are metal parts designed to fit specific needs. Unlike standard or off-the-shelf parts, these are engineered for purpose. Each component is cut, shaped, and finished based on the requirements of the product or device it supports.

They vary in size, thickness, and material. Some are simple brackets. Others are intricate parts used in satellites or medical implants. No matter the complexity, custom parts offer one major benefit—fit-for-purpose precision.

Why Precision Matters

In industries like aerospace, even a fraction of a millimeter can impact performance. In electronics, tight spacing demands extremely accurate parts. The margin for error is near zero. Precision matters.

Custom components remove the guesswork. You get exactly what your design calls for. That precision boosts efficiency, reduces waste, and extends the life of your products.

Our Method: Photochemical Etching

At TMN Etch, we use photochemical etching to create custom parts. It’s clean, efficient, and precise. It also protects the integrity of the metal.

Here’s how it works:

1. We start with a flat sheet of metal.

2. We apply a light-sensitive material to it.

3. We expose the sheet to light through a patterned mask.

4. The exposed areas are then chemically etched away.

5. What’s left is your custom design.

This method works with many metals: stainless steel, aluminum, copper, and more. It also works for both prototypes and high-volume runs.

Benefits of Our Process

Photochemical etching offers advantages that traditional methods can’t match:

• No mechanical stress: Unlike stamping or machining, our process doesn’t bend or warp the metal.

• Complex shapes: We can create micro-holes, thin walls, and delicate structures.

• Fast turnaround: No tooling means we go from design to part in days—not weeks.

• Cost-effective: Especially for complex or low-to-mid volume projects.

These benefits translate into better results for our clients. They get parts that perform well and last long.

Who Needs Custom Metal Components?

Many industries depend on precision metal components. Let’s look at a few:

Aerospace

Aerospace applications require light, strong, and precise parts. Every ounce counts. Our etched parts include filters, sensors, shields, and connectors. These components perform under extreme conditions.

Medical Devices

Surgical tools and implants must meet high safety standards. Our process delivers clean, burr-free edges and exact specifications. We produce parts like catheter components, micro screens, and surgical blades.

Electronics

Modern electronics are smaller and more powerful. That requires detailed metal parts that fit into tight spaces. We create lead frames, EMI shields, connectors, and flexible circuit parts.

Automotive

From EV battery systems to transmission parts, automakers rely on custom metal solutions. We produce thin washers, gaskets, heat shields, and more.

Industrial Equipment

Machines need reliable moving parts. We make gears, spacers, screens, and housings that stand up to harsh conditions.

Materials We Work With

Different applications need different materials. At TMN Etch, we work with:

• Stainless steel: Strong, corrosion-resistant, and ideal for medical and food-grade parts.

• Copper: Great for electrical conductivity and used widely in electronics.

• Aluminum: Lightweight and strong. Perfect for aerospace and automotive use.

• Nickel alloys: High-performance and heat resistant. Used in energy and defense.

We help you choose the best material for your project. You’ll get parts that meet your needs without compromise.
