Laser blanking service

Ⅰ. Advantages of laser blanking line

        1、Flexibility                        

            a) No die investment; Shorten project development cycle 
           b) No restrictions on sheet design and optimization
           c) Capable of producing different shapes simultaneously
           d) Capable of processing different materials, such as aluminum, high strength steel, and composites ,etc. 
           e) Quick change-over to produce different types of product
           
        2、Materials use
            a) Material consumption is reduced by 5% or more compared to traditional blanking
            b) Using more economical sized rolls

        3、Quality

Ⅲ. Greatly improve material utilization and reduce material consumption
        1. Layout optimization is highly flexible, reducing waste by optimizing layout 
        2. Material consumption is reduced by 5% or more compared to traditional blanking
        3. Using more economical sized rolls

        a、 Material utilization improvement case (B pillar)：

Traditional blanking		Laser blanking
Square plate area：1257*700=879900 Material utilization： 320330*2/879900=72.81%		Square plate area：1350*600=810000 Material utilization： 320330*2/810000=79.09%
Laser blanking increase 6.28 % in material utilization

        b、Material utilization improvement (A pillar)：

Traditional blanking		Laser blanking
Square plate area：1500*387=580500 Material utilization： 384908/580500=66.35%		Square plate area：1215*1770.5=2151157 Material utilization： 384908*4/2151157=71.57%
Laser blanking increase 5.22 % in material utilization

Ⅳ. Cutting quality

High strength steel and aluminum alloy materials in traditional stamping blanking process prone to sheet surface crush and cracks (as shown in the right) which eventually may lead to parts cracking .         Laser blanking works in a in contactless way, using high power density spot formed by laser beam focusing to heat the material quickly to vaporization temperature. After generating air holes, making the beam move relatively to material to obtain a narrow continuous slit. Finally obtain better edge cutting quality than stamping blanking.

Ⅴ. NPI Time and Cost Improvement

        Traditional stamping process requires a long die production cycle, normally it takes 3-6 months to develop a new set of blanking die. Considering the lead time of experiment and optimization, it also requires 2-4 more weeks to go into mass production after finishing experiments. The whole process is long and expensive. Normally speaking, opening a set of single process blanking die requires 15-20 million die cost, opening a set of progressive die requires roughly a million die cost.

        Laser blanking doesn’t have die request. Within only one day or even several hours, programming can be completed. If using die, even a small design change could cause plenty of work and higher cost. CAD software is used to draw up laser blanking design.
Expensive changes that took long time to complete are now almost inexpensive and can be easily achieved.
