Microfluidic Plastic Chips是一种在微尺度上进行流体操控和分析的创新性技术,广泛应用于生物医学、化学分析和实验室研究等领域。
为了实现对这些微型芯片的批量生产,注塑技术被广泛采用,为其生产提供了高效、精确和经济的解决方案。
注塑是一种通过将熔融塑料注入模具中,然后冷却固化成形的制造过程。在微流控塑料芯片的生产中,该方法具有诸多优势。
首先,注塑技术能够在较短的时间内完成大规模生产,提高生产效率。其次,通过模具设计和优化,可以确保微流控芯片的精准尺寸和形状,保证了芯片在实际应用中的可靠性和稳定性。
此外,注塑还具有较低的生产成本,有利于大规模生产中的经济效益。
微流控塑料芯片的注塑生产过程通常包括以下几个关键步骤。
首先,选择合适的塑料原料,这可能涉及到对原料性能的详细了解和筛选。
其次,设计和制作精密的注塑模具,模具的设计直接影响了最终产品的质量和性能。
然后,将选定的塑料原料在高温下熔化,注入模具中,并通过冷却系统迅速冷却和固化。
最后,取出成形的微流控塑料芯片,进行后续的检测、包装和质量控制。
In bulk production, establishing a scientific production plan and management process is crucial. Continuous monitoring and adjustment of parameters during the production process ensure product consistency and stable quality. Additionally, effective coordination and cooperation with the supply chain are key factors in ensuring production efficiency and product quality.
In summary, adopting injection molding for the mass production of microfluidic plastic chips is an efficient, controllable, and cost-effective manufacturing method. Through precise process control and sound production management, large-scale production of microfluidic chips can be achieved, providing stable and reliable experimental tools for both research and practical applications.
During the functional verification stage, machining is employed to process channels on the material surface. This method is time-efficient, cost-effective, and enhances efficiency while saving on verification costs.
Processing capabilities:
> Achievable channel width: ≥30um
> Processable materials: PMMA, COC (can provide the required sheets for processing), PS, PC
>Aspect ratio (depth to width ratio): 1:1~1:3
Once chip validation is complete and before entering the mass production phase, mold injection is conducted for further product structure verification. In this stage, injection molding is used. In the early stages of mold preparation,we can provide standard mold bases, allowing customers to design and process channels within our specified mold cavity dimensions. We have a mature process matching, and customers only need to focus on the chip structure itself.。This way, customers only need to prepare the mold core, use our standard mold base, saving time and costs.
Mold processing capabilities:
1)Mold materials: S136, Borofuse special materials
2)Line size: ≥30um
3)Surface finish: <Ra20nm
4)Mold hardness: HRC40
5)CNC: Achieves 4-axis, 5-axis, 6-axis machining with an accuracy of up to ±5um
6)Achievable mold cycles: ≥300,000 times
We have a 2000m2 clean workshop equipped with 20 German-imported injection molding machines, ensuring the fulfillment of customer requirements.
