How to Prevent Heat-Induced Deformation in Laser Machining

Laser processing of highly reflective materials—such as copper, gold, and aluminum—presents unique challenges due to their high thermal conductivity. Heat is quickly dispersed throughout the material, enlarging the heat-affected zone (HAZ), altering mechanical properties, and often resulting in edge burrs and thermal deformation. These issues can compromise precision and overall product quality. However, several strategies can effectively mitigate these thermal challenges.

1. Optimize Laser Parameters

Adopting short-pulse lasers, such as picosecond or femtosecond lasers, can significantly reduce thermal impact. These ultra-short pulses act like precision scalpels, delivering energy in concentrated bursts that limit heat diffusion. However, determining the ideal combination of laser power and scanning speed requires thorough experimentation. Excessive power or slow scanning may still cause heat accumulation. Careful calibration of parameters ensures better control over the process, reducing unwanted thermal effects.

2. Apply Supporting Techniques

Local Cooling: Using industrial laser chillers for localized cooling can rapidly dissipate surface heat and limit heat spread. Alternatively, air cooling offers a gentler and contamination-free solution, especially for delicate materials.

Sealed Chamber Processing: Conducting high-precision laser machining in vacuum or inert gas environments within a sealed chamber reduces thermal conduction and prevents oxidation, further stabilizing the process.

Pre-Cooling Treatment: Lowering the material's initial temperature before processing helps absorb some of the heat input without exceeding thermal deformation thresholds. This technique minimizes heat diffusion and improves machining accuracy.

By combining laser parameter optimization with advanced cooling and processing strategies, manufacturers can effectively reduce thermal deformation in highly reflective materials. These measures not only enhance laser processing quality but also extend equipment longevity and improve production reliability.

Laser drilling in ceramics of electronics and semiconductor components

The laser technique used in ceramics of electronics and semiconductor components mainly includes laser drilling.

Aluminium oxide ceramics and aluminum nitride ceramics feature high heat conduction, high insulation and high temperature resistance, so they have wide applications in electronics and semiconductor areas. However, these ceramics materials are very hard and brittle, so the machine-shaping process is not easy. The micro hole is particularly hard to form. Since laser features high power density and good directivity, it is often used to perform drilling on ceramics. The laser beam is focused on the workpiece through a optical system. The high power density laser light will melt and evaporate the materials and then an air current coming from the laser head will blow away the melted materials and it will form a hole. 

As we know, electronics and semiconductor components have small size and high density, so laser drilling on them is expected to be highly precise and efficient. The common laser source used in laser drilling on ceramics is UV laser. It features very small heat affecting zone and doesn’t damage the materials, which makes it the ideal tool to perform drilling on the ceramics materials of the electronics and semiconductor components. 

To maintain the superior effect of UV laser, it is suggested to add an industrial laser chiller. S&A Teyu CWUL-05 laser water chiller is ideal for cooling UV laser from 3W to 5W. It has properly designed pipeline which can avoid the generation of the bubble. In addition, this industrial laser chiller features ±0.2°C temperature stability, so it is doing a good job in controlling the temperature of the UV laser.

A Canadian Laser Cleaning Machine Supplier Entered a Partnership with S&A Industrial Laser Chiller

 Last week, Mr. Smith, who is the boss of Canada based laser cleaning machine supplier, signed the partnership agreement with us online. And we now enter a partnership for the following 5 years. The partnership specifies that we supply 200 units of air cooled chiller system CW-6200 annually. According to Mr. Smith, those industrial laser chillers will go with their laser cleaning machines as the standard accessories.

As an experienced laser supplier, he deeply knows that how important an industrial laser chiller is to the laser cleaning machine. Since laser cleaning machine uses high energy laser beam to remove the rust, plaint and other unpleasant stuff, the stability of the laser output is the top priority and proper cooling can help maintain the laser output. Therefore, he decided to select S&A air cooled chiller system CW-6200 to cool the laser cleaning machine.

Air cooled chiller system CW-6200 is characterized by 5100W cooling capacity and ±0.5℃ temperature stability. As we know, the higher the temperature stability, the smaller water temperature fluctuation will be. This is crucial to the stability of the laser output of the laser cleaning machine. Equipped with a water level check on the rear, this chiller enables easy-to-read water level when it comes to water filling, which is very user-friendly.

A Korean Client Will Integrate S&A Industrial Water Cooling System RMFL-1000 in His Handheld Laser Welding Machine in the Coming Laser Fair

Last week, a Korean handheld laser welding machine manufacturer left a message in our website, saying that he wanted to purchase several industrial water cooling systems that will cool the handheld laser welding machines in the coming laser fair. Since his booth in the fair is not big, those cooling systems are expected to be small and will be more terrific if they can be integrated into their welding machines. Well, we recently developed a new chiller model that is specially designed for cooling handheld laser welding machine - RMFL-1000.

S&A industrial water cooling system RMFL-1000 can be integrated into the handheld welding machine because of its compact design, which is great for the users who have limited space. It is the newly developed industrial water cooling system of S&A and it is equipped with water pump of high pump lift & pump flow and compressor of famous brands. In addition, industrial water cooling system RMFL-1000 has dual temperature control system applicable to cool the laser source and the welding head, which is very convenient.

Why the acrylic laser engraving machine industrial chiller system has the E1 alarm?

S&A industrial chiller system which cools acrylic laser engraving machine indicates different alarm codes for different situations. We now list them below:

E1 - ultrahigh room temperature;
E2 - ultrahigh water temperature;
E3 - ultralow water temperature;
E4 - faulty room temperature sensor;
E5 - faulty water temperature sensor;

E6 - water flow alarm

When the alarm code shows up, there also will be beeping. In this case, press any button and the beeping will stop. However, the alarm code won’t be disappear until the related problem is solved.

E1 alarm stands for ultrahigh room temperature. Therefore, users are suggested to put the industrial chiller system in the well-ventilated place with the ambient temperature below 40 degree Celsius.

After 17-year development, we establish rigorous product quality system and provide well-established after-sales service. We offer more than 90 standard water chiller models and 120 water chiller models for customization.

Can laser marking machine work normally when it is overheated?

Laser marking machine is not supposed to run in high temperature. Otherwise, breakdown problem is likely to occur which will damage the inner components. Therefore, it is necessary to add an external cooling unit to the laser marking machine. Based on the cooling method that the laser marking machine requires, users can select air cooling or water cooling. For water cooling, it is suggested to use industrial chiller unit which can regulate the water temperature for the laser marking machine.

After 17-year development, we establish rigorous product quality system and provide well-established after-sales service.
