Microfluidic Chip Plastic Moulding
1. We build different kind of microfluidic chips with different function.
2. There are many micro feature on the part, so the mold design, Precision of processing equipment is very critical. The injection machine need to keep the same machine for mold testing and mass production.
3. The flatness, consistency and sharp angle is difficult to control. But they are very important for the part function. We've got a lot of experiencein molding this kind of parts.
- Fast Delievery

Successful Experience
34 years focusing in plastic injection molds
1. The parts is used for COVID-19, genetic, infectious and epidemic disease detection.
2. The flatness what we can achieved is 0.05mm.
3. Minimum size of microarray: 100um
4. Test the mold as per scientific mold trial like checking viscosity, filling balance, gate freezing, cooling etc. These injection parameter will be applied to the process validation.
5. Run validation before mass production. The machine, parameter, resin, location will never change easily once validated.


Quality Control
Quality is always the first
1. Use special quality tools to analysis and solve quality problem in production process, such as PPK/CPK, MSA, SPC, PPAP, APQP, FMEA, Control Plan, DOE, QFD etc.
APQP&PPAP&Quality Tools:

2. SJ Group factory has the certificates of ISO9001, IATF16949 and ISO13485.

Class 8 Clean Room
Promise the quality
Class 8 clean room with 89 sets fully imported high precision injection machine. The brand is Sumitomo, Toshiba, Fanuc, TOYO etc. The environment and quality system is controlled strictly by ISO13485.
