Epoxy resin material, suitable for casting PDMS chips, combines the precision of SU8 molds with the durability of conventional acrylic molds.
Resin molds are typically prepared by first creating PDMS chips using SU8 molds/pure silicon molds and then replicating them through PDMS molding. They offer several significant advantages:
> Epoxy resin molds can accurately replicate the microstructures of PDMS chips in a highly precise manner, maintaining the accuracy and clarity of fine features.
> Epoxy Resin molds are easy to demold, requiring no complex processing steps. They possess a reusable characteristic, greatly improving preparation efficiency and reducing costs. This feature is particularly beneficial for batch production and multiple experiments.
3、树脂模具的应用显著减少了SU8模具/纯硅模具的使用频率,有效延长了SU8模具/纯硅模具的使用寿命。
树脂模具与SU-8模具或纯硅模具相比,后者不仅制备成本高昂,而且一旦受损,无法修复。相较之下,树脂模具具备多次重复使用的能力,损坏后,可以通过PDMS芯片再次进行复制。
这一工艺简便,成本低廉,尤其对于需要大规模生产和多次复制高精度微结构的PDMS芯片制备,树脂模具凭借其卓越的经济性和可靠性,表现出明显的竞争优势。
> Possesses a certain degree of transparency, allowing for transillumination to inspect the mold effect and internal structure.
> Resembles the shape of a silicon wafer, with a circular form, smooth upper and lower surfaces, and beveled edges.
> No need for hydrophobic treatment, facilitating easy demolding.
> Resistant to easy fracturing
> Surface is easy to clean and can be reused.
