Recommended Plastic Laser Engraving Machine For Metals
There are several plastic laser engraving machines you can use depending on the plastic polymer you are working with. Generally, the most common machines used are CO2 and UV laser markers due to their compatibility. Two common plastic laser markers you can consider include:
HS-UV03 UV Laser Marking Machine

The HS-UV03 plastic laser marking machine is suitable for plastic material that requires low heat. Aside from being a cold laser, it has a fiber laser marking frame of small size and compactness. Features of the machine include:
- Output laser beam power: 3W / 5W
- Marking Speed: up to 9000mm/s
- Marking Area: 100mm x 100mm (other options are available)
- Marking Depth: ≤0.2 mm
HS-CL30 CO2 Plastic Laser Engraving Machine

The HS-CL30 is a CO2 Laser Engraver suitable for deep engraving or big area marking on plastic such as ABS and polycarbonate. Features of the machine include:
- Output laser beam power: 30W
- Marking Speed: up to 7000mm/s
- Marking Area: 100mm x 100mm (other options are available)
- Marking Depth: ≤0.5 mm

How Plastic Laser Engraving Machine Works
The laser engraving plastic machine emits a high-energy light beam which the plastic material absorbs. Afterward, energy conversion to heat occurs, which is responsible for the marking.
The imprints or markings left are accomplished by different techniques, including etching, foaming, color changing, engraving, or combining those methods. However, the method’s choice depends on the material’s peculiarities and the desired result.
Challenges for Plastic Laser Marking Machine Manufacturers
Laser engraving plastic demands both a scientific and creative approach. Different material types behave differently while progressing with laser marking plastic, and there are lots of them: polypropylene, polyethylene, polyamide, acrylic, nylon, silicone and many more. Moreover, manufacturers add various additives and fillers to improve the material’s qualities, resulting in an even bigger range of types. This means not any solution can ensure quality results on your product.
If you have decided to buy a laser etching machine for plastic, make sure the chosen one handles all material sorts, natural, colored, or transparent, with different additives, like HeatSign’s solutions, do. And before you buy the marking machine, it’s better to test the device against the sample of your material.
Choosing Laser over Inkjet for Plastic Marking
Before the rise in the use of laser engraving plastic machines, inkjet marking machines were the most preferred marking machine for plastics. As of today, inkjet has long lost the competition to the laser method (except for several very specific applications) due to some uncomfortable disadvantages:
- Needs post-production
- Requires consumables and disposal of wasted resources
- Easily wears off in time or upon exposure
Laser marking technology has several advantages due to the following:
- Easy and comfortable inscribing process
- It requires only the power supply
- It produces zero waste and emission
- The imprints are very precise and permanent
- The processed plastic part is ready to be used at once.
