How to Get Custom Metal Parts Made Online in Australia

Getting Custom Metal Parts Made Has Changed

Ordering custom metal parts used to mean finding a local fab shop, emailing drawings, waiting days for a quote, negotiating on the phone, and hoping the parts matched your design. For a one-off bracket or a short run of mounting plates, the process was slow and the setup costs often made small orders uneconomical.

Online manufacturing has changed this completely. You can now upload a CAD file, get a price in seconds, pay online, and have parts delivered to your door — all without a single phone call. The technology behind instant quoting analyses your geometry, calculates cutting time from real machine parameters, and prices material automatically.

This guide walks through the full process — from preparing your design to receiving finished parts — so you know exactly what to expect.

Step 1: Prepare Your Design File

The quality of your parts starts with the quality of your file. Online quoting systems work with standard CAD formats:

DXF tips:

• Export as a 2D profile (plan view), not a 3D wireframe
• Check that all geometry is closed (no gaps between lines and arcs)
• Remove construction lines, dimensions, and text layers
• Set units to millimetres — the quoting system reads the file at face value

STEP tips:

• For bent sheet metal, model as a sheet metal part (not a solid block). The system unfolds the bends to calculate the flat pattern
• Keep wall thickness uniform — variable thickness confuses automated analysis

If you don't have CAD software, you can sketch your part on paper and send it for a manual quote, or use our DXF templates as a starting point. Our free DXF viewer lets you check your file before uploading.

For detailed DFM advice, read the Laser Cutting Design Guide.

Step 2: Choose Your Material

Material selection depends on your application. Here are the most common choices for laser-cut parts:

Mild Steel — The workhorse. Strong, weldable, affordable. Best for structural brackets, frames, enclosures, and anything that will be painted or powder coated. Available from 1mm to 16mm.

Stainless Steel 304 — Corrosion resistant, food-safe, good appearance. Costs more than mild steel but doesn't rust. Best for kitchen equipment, outdoor fixtures, marine hardware, and anything exposed to moisture.

Stainless Steel 316 — Superior corrosion resistance to 304. Use for coastal environments, chemical exposure, and marine applications. Higher cost but necessary where 304 isn't enough.

Aluminium 5052 — Lightweight, corrosion resistant, easy to form. Best for panels, enclosures, brackets where weight matters. About one-third the weight of steel.

Galvanised Steel — Mild steel with a zinc coating for corrosion protection. Cheaper than stainless but not as durable. Good for outdoor structural parts.

Not sure which material to use? Our material comparison tool shows properties side by side, and our material weight calculator helps you estimate weight and cost.

Step 3: Get a Price

There are two ways to get pricing:

Option A: Instant Quote (Recommended)

Upload your DXF or STEP file to the instant quote tool. The system analyses your geometry and returns a price in seconds. You can adjust material, thickness, and quantity and watch the price update in real time.

The price includes:

• Cutting time — calculated from your exact cut length and real laser parameters
• Material cost — based on the sheet area your part requires
• Handling — loading, unloading, deburring, basic quality check
• Setup — file preparation and machine setup, amortised across quantity

Option B: Cost Estimator (No File Needed)

Don't have a CAD file yet? Our sheet metal cost estimator gives you a rough price from basic dimensions (width, height, material, thickness, number of holes and bends). It uses the same pricing engine as the instant quote — just with estimated geometry instead of exact measurements.

This is useful for budgeting before you commit to a full design.

Step 4: Optimise for Cost

Before placing your order, consider these cost-reduction strategies:

Order more parts. Setup and handling costs are fixed per order. Going from 1 to 10 parts typically reduces the per-unit price by 40-60%. The instant quote shows pricing at different quantities.

Simplify your geometry. Every internal cut-out, hole, and slot adds cutting time. If a decorative slot doesn't serve a structural purpose, removing it saves money.

Choose the right thickness. Thicker material costs more and cuts slower. A 2mm bracket is often strong enough where someone specified 3mm out of habit. Use our K-factor calculator to check bend feasibility at different thicknesses.

Consider mild steel. If your part doesn't need corrosion resistance, mild steel is significantly cheaper than stainless or aluminium. You can always powder coat it for weather protection.

Watch your nesting. The quoting system automatically nests parts on standard 3000 x 1500mm sheets. Parts that nest efficiently (rectangular, consistent orientation) use less material waste.

Step 5: Place Your Order

Once you're happy with the price:

1. Add to cart — you can add multiple different parts to a single order
2. Enter your shipping address — delivery is calculated automatically based on weight and destination
3. Choose payment — credit/debit card or PayID bank transfer. Card payments are processed instantly through Stripe. PayID orders go through a quick manual confirmation.
4. Submit — you'll receive an order confirmation email immediately

Step 6: Production and Delivery

After payment, your order enters the production queue:

1. File review — your files are checked for any issues that could affect quality
2. Nesting — parts are arranged on sheets to minimise material waste
3. Cutting — your parts are laser cut on a 3kW fibre laser with a 3m x 1.5m bed
4. Deburring — edges are cleaned and deburred
5. Bending (if applicable) — parts with bends are formed on a CNC press brake
6. Quality check — dimensions and edge quality are verified
7. Packing and shipping — parts are securely packed and shipped via courier

Standard turnaround is 5-7 business days from payment to dispatch. Express (2-3 business days) is available at checkout for urgent jobs.

You'll receive email updates when your order enters production and when it ships with tracking information.

When to Use Online vs Local

Online quoting works best for:

• Standard sheet metal parts (laser cutting, bending)
• Parts where you have a CAD file ready
• Short runs (1-100 parts)
• When you need a quick price to budget or compare options

A local shop may be better for:

• Complex assemblies requiring welding and fitting
• Very large or heavy parts that are expensive to ship
• Jobs where you need to discuss engineering details face-to-face
• Production runs of 1000+ where setup time is a small fraction of total cost

That said, many customers use both — online quoting for the straightforward parts and a local relationship for complex assemblies.

Frequently Asked Questions

How much does custom laser cutting cost in Australia?

It depends on material, thickness, complexity, and quantity. A simple 200 x 100mm bracket in 3mm mild steel starts around $15-20 for a single part and drops to $5-8 each at quantity 10+. Use our cost estimator for a quick estimate or upload your file for an exact price.

What's the minimum order?

There is no minimum order. You can order a single part. The minimum charge for sheet metal is $47.25 ex-GST, which covers machine setup and handling regardless of part size.

Can I order without a CAD file?

Yes. You can use our cost estimator for a rough price, download a DXF template to customise, or contact us with a sketch or description for a manual quote.

What tolerances can I expect?

Laser cutting: ±0.1mm. CNC press brake bending: ±0.5°. These are standard tolerances for fibre laser cutting and CNC forming. See our tolerance guide for detailed specifications by process.

Do you ship Australia-wide?

Yes. We ship to all Australian states and territories via courier. Shipping is calculated by weight and destination at checkout.

What if my parts aren't right?

If parts don't match your file specifications, we remake them at no charge. Contact us at 07 5616 4988 or [email protected] and we'll sort it out.
