Design Guide

Wall Thickness / Radius

1× material thickness min hole diameter

Min Feature Size

2× material thickness (slots, tabs, bridges)

Surface Finish Options

As-cut, deburred, tumbled, brushed, powder coated

Design advice

1/ Keep holes away from edgesPlace holes at least 2× material thickness from any edge to prevent thermal blowout and deformation.

2/ Plan for bends after cuttingKeep cut features at least 2.5× thickness plus the bend radius away from bend lines to avoid oval stretching.

3/ Use nitrogen-cut edges for coatingRequest nitrogen assist on stainless steel and aluminum for an oxide-free edge that welds and powder coats cleanly.

Laser Cutting Materials

Our fiber lasers cut carbon steel, stainless steel, aluminum, copper and brass across standard thickness gauges.

Carbon Steel

Strong, low-cost and easy to weld. Oxygen-assist cutting gives fast, clean cuts on brackets, frames and base plates. Grades: Q235, SPCC, 1018.

Why Choose Us

Engineers and procurement teams choose Enstark laser cutting for parts that fit on the first try and arrive on schedule.

/01
High Quality Parts

Cutting accuracy holds ±0.1 mm with ±0.05 mm repeatability. Every batch is verified with calipers, pin gauges, and optical 2D measuring systems.

/02
Fast Lead Time

Simple flat parts ship in as little as 3 business days. Automatic nesting algorithms and 24/7 laser cutting cells keep orders moving.

/03
Engineering-Driven Support

Our engineers review your file within 24 hours, flagging undersized holes, tight edges, or kerf issues before cutting begins.

What is Laser Cutting?

Laser cutting is a CNC-controlled process using a high-power focused fiber laser beam to melt and vaporize metal along a programmed path. Pure assist gas (oxygen or nitrogen) expels the molten material, leaving a narrow kerf and clean edge without mechanical tool wear.

✓ISO-certified quality management system

✓High-power fiber lasers up to 12 kW

✓±0.1 mm cutting accuracy across sheets

✓Automatic nesting to reduce raw material waste

✓High-purity oxygen and nitrogen assist cutting

✓100% dimensional inspection prior to shipping

Pros and Cons of Laser Cutting

Pros of Laser Cutting

High Precision & Clean Edges

Holds ±0.1 mm with a narrow kerf, so fine slots, small holes and sharp corners need little or no rework.

No Tooling Cost

The laser follows your CAD file directly. Design changes cost nothing, making it ideal for fast prototypes.

Fast & Material-Efficient

Cuts thin sheet at high speed, and automatic tight nesting utilizes maximum material from every sheet.

Cons of Laser Cutting

Thickness Limits

Optimal below 20 mm steel and 12 mm aluminum. Thicker plate is better suited to waterjet or plasma cutting.

Heat-Affected Zone

A narrow heat-affected zone forms on steel, and oxygen cutting leaves an oxide layer that may need cleaning.

Reflective Metal Limits

Copper and brass reflect laser energy, capping practical cut thickness at about 5 mm.
