These are the most frequently used processes for laser engraving

Deep engraving:


In the manufacture of tools and molds or also for vehicle identification numbers, deeper laser engraving up to the millimeter range must be used. To achieve the required depth, it is often necessary to carry out a treatment layer by layer.

Black engraving:

In laser personalized engraving of metals, the interaction between the molten base material and atmospheric oxygen generates oxides which are distinguished by their color. The usually quiet rough surface absorbs a lot of light and that is why the marking normally appears in black or, depending on the material, dark gray (aluminum) or dark brown (steel, brass, copper).

White engraving:

With white engraving, the surface is structured in such a way that the material is only slightly melted. This results in a smooth, highly reflective surface - in the case of materials such as galvanized steel, this appears as a white marking. Due to the shallow penetration depth, the coating remains intact and corrosion-resistant.

High contrast white engraving is particularly beneficial on dark metals such as hardened steel. When applying Data Matrix codes, a combination of black and white engraving is particularly suitable. The contrast is increased and the quality and readability of the code are improved.

If for some reason your hormone levels are disrupted, your ovulation may be affected. Most women will experience anovulatory menstrual cycles at some point in their reproductive life. This phenomenon is more common in young women who have just had their period, or in older women approaching menopause. However, anovulatory cycles can also occur in healthy women who have regular periods. Some women suffer from chronic anovulation; this may be an indication of an underlying hormonal condition, such as polycystic ovary syndrome (PCOS), which can make natural conception more difficult. An irregular or missing period can be a sign of potential ovulation problems. Many factors can be at the origin of the hormonal imbalance affecting ovulation. These include significant weight change, stre...
