Acrylic microfluidic channels available from a single unit

Customer's Challenge

Customer would like to have a microfluidic channel bonded with an acrylic cover manufactured starting from a single unit.

CSTEC's Proposal

The acrylic microfluidic channel requested this time was manufactured using cutting processes such as plotter machining and laser processing.
The double-sided adhesive tape used to bond the cover to the channel was die-cut into the same pattern as the microchannel grooves, and then applied for bonding.
When manufacturing microfluidic channels through acrylic machining, adhesives are commonly used to bond the channel and the cover. However, there is a risk of the adhesive seeping into the microchannels, which can make it difficult to maintain stable quality. In contrast, using double-sided tape eliminates the risk of adhesive overflow into the channels.
At CSTEC, we are capable of die-cutting and laser processing adhesive tapes with dimensions nearly identical to the microchannels, enabling highly accurate bonding between the channel and the cover.
In addition to acrylic, we can also apply this tape-bonding method to other plastic molded products. We welcome small-lot prototyping, so please feel free to contact us.

(A sales representative, Mr. S, came to the factory's cleanroom for the launch of a new product and to ask a difficult process to Mr I.)
Mr. S： "This is quite a challenging lamination...how do you think, Mr. I?"

Mr. I： "This is tough, though… I think it would be better if the customer could relax the standards a little."

Mr. S： "Is there any way to achieve this work? Please!"

(Thanks to Mr.I's efforts, we managed to meet the standards - but the next process will be tough... Let's ask Mr.T's help!)
Mr. S： "I would like to ask your help to overcome this level of precision..."

Mr. T： "That is really pushing it, however, I will do my best!"

Thanks to the factory's hard work, we were able to deliver a product that satisfied the customer.

At CSTEC, we have a culture of never giving up on difficult processing challenges. Before saying "No", we always try to take on the challenge. So please feel free to ask us!
