FAQs:

【Stainless Steel Engraving】Engraving stainless steel only needs a small enough focus point and enough light power, F30130,A40640, A40630 and A30130 Compressed Spot Module, Support for Marking Metal engrave stainless steel.and N40620 and N40630 modules can engrave stainless steel by painted.

【Air Assist Sets】NEJE provide 2 types of air assist sets. One is specially designed for F30130 modules and requires a dry air compressor to provide support, the other is a fixed stainless steel tube that can support other NEJE modules. NEJE 3D printing drawings are provided, which can be downloaded at neje.wiki. These 2 air assist sets support 1.5mpa pressure, which can greatly improve the depth of engraving and cutting.

【What Does Standard for a Reliable Laser Module Have?】 Laser modules need to undergo an aging test to determine whether the heat di

ssipation of the module can match the requirements. The NEJE module has a built-in temperature sensing inside, and the 60mm threaded copper is attached with high thermal conductivity silicone grease, which can quickly export heat to make sure the temperature is controlled to keep a safe range. If the temperature and heat dissipation of the module cannot match the requirements, it can be screened out in the production process. At present, there is no module with temperature for sensing function to ensure a reliable service life in this industrial.

【How to Choose a Module?】Cutting – If you are only cutting applications within 6mm, NEJE recommends N40620 and N40630 are nice choice. These two modules can cut 2-3mm plywood under air assist mode. If you want to cut 6-12mm, you can choose A40630 and A30100 and A40640 module. If there is a requirement for cutting of speed, the A40640 module is recommended, F30130 is suitable for users who have requirements for work efficiency and air compressor equipment. This module can cut 2-4mm plywood at a time with a maximum thickness of 4mm, It adopts a very simple focusing method. The focal length of 5mm can block more than 95% of the light and safe to use. If you often engrave portraits, you just need one of the NEJE B40635 405mm modules, this module is the current 405mm maximum optical power module, the 405mm module has a very good grayscale outcome. If you are just for a simple engraving, N30610 or B30635 will perfect match for you.

【100% Satisfaction】NEJE factory are proud to provide the process of 48-hour temperature control for aging test to ensure the quality of each module and guaranteed 2 years (20,000 hours) free warranty.
