In the domestic market for teaching aids, the core of Punett ' s ability to maintain a competitive advantage is not just brand marketing, but the continuous accumulation of deep-tilled technologies. Since the establishment of the Technology Research and Development Centre in 2010, the team has invested approximately 120 million yuan a year in materials development, digital modelling and process optimization, with a cumulative total of 45 patented inventions and 28 new and practical patents, creating a closed-ring technology chain from concept to product.
The R & D team uses the "two-track parallel" model: one orbit focuses on the geometric accuracy of the bio-understanding anatomical model and another orbit focuses on the simulation of functional material. The introduction in 2021 of a polykinetic simulation platform brought the skeletal joint model down to 0.3 per cent in the stress test, well below the industry average of 1.2 per cent. The platform ' s core algorithm is based on the United States MIT ' s limited meta-analysis framework, which has been improved by localization and is retrofitted in real time.
In material selection, Punet insists on the use of a combination formulation of medically grade polyurethane and biocompatible resins. The Low Temperature Convergence Process, completed in 2022, allows for solidification at 20°C, both to ensure the complete preservation of the details of the model and to control the hardness fluctuations at 5%. In the same year, in conjunction with the high-precision FDM printer of Ultimaker S5 Pro in Germany, the thickness of the layer achieved a μm resolution of 0.05 mm and the vascular branch details of the single heart model increased from the original 5 mm thick line to 0.8 mm thin.
In order to meet the cross-cutting needs of health care, life sciences and engineering education, the "modularized assembly platform" was installed in Punet. For example, the Experimental Respiratory Package, developed in cooperation with a university in Shanghai in 2023, integrates pulmonary elastic materials with visualized air current sensors, and students can read resistance curves in real time in simulated respiratory cycles. Experimental data show that the average score of students using the package was 18 points higher in the CPR test.
Quality management is no longer a sample test, but a full-process data tracking. Each of the products out of the plant is equipped with a 2-D code, which shows production batches, material matching, 3D print parameters and a 3-D coordinate deviation report. Internal audits in the first quarter of 2024 showed that the rate of back-up based on large-data early warning had decreased from 2.4 per cent in the previous year to 0.9 per cent. This transparent quality closure remains rare in the field of teaching aids in the country.
The fall of technology has made every one of Punett's trajectories look like a precise conversation about the teaching landscape. Standing in front of the lab's workstation, seeing a hand holding a just printed neurological model, and feeling the dark lights behind dozens of engineers?
Participation in discussions
That's a good number. Forty-five invention patents.
It's kind of cold in here, and I can't believe that companies are willing to spend so much on research and development.
120 million years... how do you figure out the size of this input?
The anatomy model of their home, which was previously represented, was indeed one step higher than that of their peers.
The 0.9 per cent return rate is a bit false, too much.
Can anyone read this technical article?
Half a day, I remember that 0.05 mm thick, and the rest is digital.
Do you know which hospital they work with?
That's good.
