For such work, Raycus/IPG cannot mark black color, so you have to choose MOPA laser if you need marking black color on Iphone housing.

# Marking colors on stainless steel
Some people told me only MOPA laser can mark colors on SS. It is a mistake. Raycus laser/IPG laser also can mark colors on SS, just their pulse width is fixed, the parameters are not so easy to get for new beginner.
MOPA laser pulse width can be adjusted, so it is a little easier to get color marking parameters compare with Raycus/IPG laser. But it also need time. As my opinion, it is not necessary to buy one MOPA laser which only for marking colors on SS. Because marking colors speed is lower, most of seller only use color marking sample for get customer’s attention. But if you have to do such work, then  you choose MOPA laser. The choices are yours.

# Marking PVC card with more smooth results.
Same as above mentioned, Raycus/IPG/MOPA laser all can do PVC card, just if you use MOPA laser, when your finger touch the results, you may cannot feel the marking outline; but if you touch the results made by Raycus/IPG laser, you may can feel it is indeed existed. (Plastic is a complex material, some content is different, results are different, sometimes you need UV or green laser. Here i cannot promise you fiber laser can mark your PVC card in best results.)

So if your 80% work is in same range as above information, then you choose MOPA laser. Or you choose standard Raycus/IPG laser.
