Silicon Based Chip
·Product Description
Silicon-based microfluidic chips are miniaturized fluid control systems fabricated from silicon materials, designed to handle and manipulate microfluids (volumes down to nanoliters) within micro-scale channels (tens to hundreds of micrometers). These chips enable highly integrated and automated chemical, biological, and medical analyses. Thanks to silicon's excellent chemical stability, thermal resistance, and mechanical strength, it serves as an ideal substrate for demanding applications such as microreactions and biosensing. Building on the core advantages of microfluidic technology and leveraging semiconductor manufacturing processes, silicon-based chips allow for the fabrication of complex structures with high precision and consistency, making them suitable for harsh biochemical environments and long-term implantable applications.
· Technical Features and Application Areas
Silicon-based chips offer unique capabilities in controlling fluid behavior at the micro-scale, such as laminar flow and droplet formation, enabling high-throughput screening, cell culture, drug synthesis, and single-molecule analysis that are challenging with conventional methods. Key application areas include:
1. Medical Diagnostics: Rapid disease detection, gene sequencing (DNA analysis), and point-of-care testing devices
2. Pharmaceuticals and Synthesis: Used as microreactors for drug screening and chemical synthesis, resistant to high temperatures and corrosive conditions
3. Implantable Devices: With excellent biocompatibility and stability, silicon is suitable for long-term implantable bio-monitoring and drug delivery systems
4. Compared to common polymer materials, silicon offers superior reliability, service life, and precision, especially under extreme conditions.

1.Customers' demand for mass production of microfluidic chips
The customer put forward the demand for batch production of microfluidic chip injection molding:
1) The customer provides microfluidic chip design drawings. According to the chip design drawings and the purpose of the customer's chip design, technicians evaluate the chip design drawings and determine the chip design drawings with the customer.
2) The customer provides the functions to be realized by the chip. Hanhao technicians design the chip according to the functions, evaluate the realization of the chip functions, and determine the chip design drawings with the customer.
2.Feasibility evaluation of injection mold opening
According to the chip drawings, the technical evaluation of the development of the injection mold is carried out, such as the appearance, material, total thickness, channel size, depth width ratio, dimensional accuracy, tolerance, surface finish of the microfluidic chip, the way of the mold inlet, the arrangement of the product in the mold, the arrangement of the product removal thimble, and the subsequent sealing of the chip. The feasibility of open mold injection molding is evaluated in all aspects.
3.Sign sales contract
After the evaluation, it is determined that the injection mold can be opened according to the customer's needs, and a contract can be signed with the customer.
4.Mold design and development
According to the requirements of customers, based on the experience of microfluidic chip injection molding batch production, a comprehensive pre evaluation of mold design was carried out. According to the mold evaluation data in the early stage, the technical team carried out mold cooling water path design, product gate layout design, product removal design in the mold, mold two or three plate mold design, mold slider design, and exhaust slot design.
5.Mold processing
The imported Makino v331 and v56i high-speed CNC machining centers and other imported equipment are used for mold processing to ensure the processing accuracy of mold parts.
