In the manufacturing of LED cutting equipment, the granite base is a key component that ensures cutting accuracy. Some enterprises choose low-grade granite bases to reduce initial investment, but they are unaware that this decision may bring about hidden costs far exceeding expectations. These hidden costs are like "financial black holes", quietly eroding corporate profits.
High rework costs caused by precision loss
The mineral structure of low-grade granite is loose, and its coefficient of thermal expansion is unstable. It is prone to deformation under the influence of environmental temperature. During the LED cutting process, the local high temperature brought by the laser energy will cause slight deformation of the low-grade granite base, resulting in a shift of the cutting focus. This leads to an increase in the size error of the cut LED chips and a decrease in the yield rate. According to industry data statistics, using low-grade granite bases may increase the size deviation rate of LED chips by 15% to 20%. The resulting rework and scrapping costs may cause enterprises to spend hundreds of thousands of yuan more each year. If customers return goods or claim compensation due to precision issues, the losses will be incalculable.
Frequent maintenance drives up operating costs
Low-grade granite has poor hardness and wear resistance. Under the vibration and impact of long-term operation of the equipment, the surface of the base is prone to wear and scratches. To ensure the cutting accuracy, enterprises need to calibrate, grind and repair the base more frequently. Compared with the calibration cycle of 1 to 2 years for high-quality granite bases, low-grade bases may need maintenance every 3 to 6 months, with each maintenance cost ranging from several thousand to tens of thousands of yuan. At the same time, frequent maintenance will also lead to increased equipment downtime, reduced production efficiency, and the indirect losses should not be underestimated either.
The replacement cost caused by the shortened service life of the equipment
Due to the poor physical properties of low-grade granite, it cannot effectively attenuate the vibration during equipment operation, which will accelerate the wear of other key components of the LED cutting equipment, such as guide rails, motors, and laser heads. The core components of the equipment age prematurely, significantly shortening their service life. Originally, cutting equipment that could be used for 5 to 8 years may need to replace key components every 3 to 5 years due to quality issues with the base, or even replace the entire equipment ahead of schedule. The procurement cost of an LED cutting device can be as high as several million yuan. The huge expenditure brought about by replacing the equipment in advance will impose a heavy economic burden on the enterprise.
The potential costs that affect a company's reputation
Long-term use of low-grade granite bases leads to unstable product quality, which will affect the image and reputation of the enterprise in the minds of customers. Once customers develop a trust crisis in the enterprise due to product quality issues, not only may existing orders be lost, but it will also affect the cooperation intentions of potential customers. The time and cost required to rebuild an enterprise's reputation are difficult to quantify, which may put the enterprise at a disadvantage in market competition and cause it to miss development opportunities.
Choosing low-grade granite bases can reduce the initial procurement cost, but in the long run, the hidden costs such as precision loss, frequent maintenance, equipment replacement and reputation damage will bring huge economic pressure to the enterprise. In the field of LED cutting equipment manufacturing, to ensure product quality and the economic benefits of the enterprise, choosing high-quality granite bases is a wise choice.
