PDMS-specific CO₂ laser cutting and engraving machine: A high-precision solution for microfluidic chip manufacturing

PDMS-specific CO₂ laser cutting and engraving machine — a high-precision solution for microfluidic chip manufacturing

With the rapid development of microfluidic technology, PDMS (polydimethylsiloxane) has become the core material for manufacturing microfluidic chips due to its excellent biocompatibility, transparency and plasticity. However, traditional PDMS processing relies on mold forming and manual cutting, which has pain points such as low efficiency, poor precision and high cost. In response to this industry demand, we have launched a PDMS-specific CO₂ laser cutting and engraving machine. Taking non-contact laser processing technology as the core, we provide efficient and precise microfluidic chip processing solutions for scientific research institutions and biomedical enterprises.

Core technical advantages of the product
High-precision and damage-free cutting
Equipped with a 10.6μm wavelength CO₂ laser, specially optimized for organic materials such as PDMS, it features high cutting accuracy with a minimum line width of 30μm, easily realizing one-time forming of complex structures such as microchannels and chambers, avoiding edge tearing or deformation caused by traditional die processing.

Intelligent processing system
It is equipped with high-speed galvanometers and professional PDMS cutting software, supports direct import of design files from AutoCAD, CorelDraw and other software, automatically optimizes the processing path, and ensures efficient restoration of complex graphics. The optional CCD visual positioning system realizes automatic material alignment to meet the needs of mass production.

Clean and pollution-free processing technology
Laser non-contact processing does not require physical molds, eliminating the risk of impurity introduction; there is no dust residue during the cutting process, and the edge is smooth and burr-free, ensuring the cleanliness of the chip, which can be directly used in biological experiments such as cell culture and drug screening.

Multi-functional compatible design
In addition to PDMS, it can also process auxiliary materials such as PET films and PI flexible circuit boards, supports multiple processes such as cutting, punching and surface micro-engraving, and adapts to the entire process requirements of chip packaging, electrode integration and other aspects. The working area of the equipment ranges from 700×500mm to 1000×600mm, meeting different scenarios from scientific research grade to industrial grade.

Application scenarios and values
Scientific research and innovation: Accelerate the iteration of microfluidic chip prototype design, with a single processing time of only a few minutes, helping laboratories quickly verify new structures such as fluid mixing and droplet generation.

Precision medicine: Provide high-consistency processing services for organ chips and portable diagnostic equipment, reducing the impact of batch differences on test results.

Industrial mass production: Preset parameters through automated software to achieve 24-hour continuous and stable production, with a comprehensive cost reduction of more than 40% compared with traditional processes.
